inside a path's string, like "/a-configs-folder". JEST_JUNIT_ADD_FILE_ATTRIBUTE: addFileAttribute: Add file attribute to the output. If a file matches the specified glob pattern, coverage information will be collected for it even if no tests exist for this file and it's never required in the test suite. Jest's configuration can be defined in the package.json file of your project, or through a jest.config.js, or jest.config.ts file or through the --config option. With this option, you can overwrite this behavior and include otherwise ignored files in code coverage. babel or typescript) to perform transformation. We’re going to add a globalSetup reference in our jest.config.js file. Note: Setting this option overwrites the default values. Beware: Jest uses node-notifier to display desktop notifications. The module must export a class with setup, teardown and runScript methods. To use my-serializer-module as a serializer, configuration would be as follows: În cele din urmă testul ar arăta după cum urmează: Pentru a face o dependenţă explicită, nu implicită, puteţi apela expect.addSnapshotSerializer pentru a adăuga un modul pentru un fişier individual de test, în loc de adăugarea sa în configurarea snapshotSerializers. If custom reporters are specified, the default Jest reporters will be overridden. Equivalent to calling jest.resetAllMocks() before each test. Automatically reset mock state between every test. Thresholds can be specified as global, as a glob, and as a directory or file path. Component.test.js or Component.spec.js). The transform config just tells jest to use ts-jest for ts / tsx files. Note: Setting this option overwrites the default values. statements: -10 implies that no more than 10 uncovered statements are allowed. This config option lets you customize where Jest stores snapshot files on disk. Test environment options that will be passed to the testEnvironment. This processor must be a node module that exports a function expecting an object with the following structure as the first argument and return it: This option allows the use of a custom test runner. I’ve named mine jest.setup.js and it lives right alongside the Jest config file. Whether to use watchman for file crawling. Because this retrofits all executed files with coverage collection statements, it may significantly slow down your tests. Jest's configuration can be defined in the package.json file of your project, or through a jest.config.js, or jest.config.ts file or through the --config option. If you want to use it to compile JavaScript code it has to be explicitly defined. A list of reporter names that Jest uses when writing coverage reports. Math). There are times where you only want Jest to search in a single sub-directory (such as cases where you have a src/ directory in your repo), but not the rest of the repo. Component.test.js or Component.spec.js). displayName defaults to white when its value is a string. It is reflected in properties such as location.href. Directorul rădăcină în care Jest ar trebui să caute teste şi module. By default, Jest runs all tests and produces all errors into the console upon completion. Make calling deprecated APIs throw helpful error messages. If you put your Jest config inside your package.json and want the root directory to be the root of your repo, the value for this config param will default to the directory of the package.json. This option allows you to use a custom runner instead of Jest's default test runner. Exclude/ignore file from Jest coverage at the file level. In-depth Explanation on Jest config ‘setupFiles’ Prior before we running every test file, we will be running all the path that declare in setupFiles . See babel-jest plugin. your package.json to store Jest's config, the "jest" key should be used on the additional locations to search when resolving modules. Use the string token to include the path to your project's root directory to prevent it from accidentally ignoring all of your files in different environments that may have different root directories. If you are building a node service, you can use the node option to use a node-like environment instead. It's generally a best practice to keep this list as small as possible and always use explicit jest.mock()/jest.unmock() calls in individual tests. Notă: În mod implicit, roots are o singură intrare , dar există cazuri în care v-ați dori să aveţi mai multe rădăcini într-un proiect, de exemplu roots: [" /src/", "< rootDir>/tests/"]. The test runner module must export a function with the following signature: An example of such function can be found in our default jasmine2 test runner package. Note that using '' as a string token in any other path-based config settings will refer back to this value. Acest instrument de rezolvare trebuie să fie un modul Node care exportă o funcţie ce aşteaptă ca prim argument un şir de caractere pentru calea de rezolvat şi un obiect cu următoarea structură ca al doilea argument: Funcţia ar trebui să returneze fie calea către modulul care ar trebui să fie rezolvat sau să arunce o eroare în cazul în care modulul nu poate fi găsit. Here are sample valid values. [jt]sx?$": "babel-jest"} to the transform property. În general este o bună practică pentru a păstra această listă cât mai scurtă posibil şi folosirea explicită a jest.mock() / jest.unmock() în teste individuale. If enabled, the module registry for every test file will be reset before running each individual test. Example: ["/build/", "/node_modules/"]. Add "text" or "text-summary" to see a coverage summary in the console output. You can create your own module that will be used for setting up the test environment. În cazul în care calea de fişier se potriveşte cu oricare dintre modele, atunci când acesta este actualizat, nu se va declanşa o re-rulare a testelor. elements. along with any other options: ["node_modules", "bower_components"]. Example: see the examples/typescript example or the webpack tutorial. Acest lucru va conduce la eliminearea implementării false pentru toate dublurile, dar nu restaurează implementarea lor iniţială. Allowed values are babel (default) or v8. With this option you can specify extra properties to be defined inside the vm for faster lookups. This is true for arrays of module names as well. GitHub Gist: instantly share code, notes, and snippets. If the test path matches any of the patterns, it will not be transformed. Indicates whether the coverage information should be collected while executing the test. Default: The root of the directory containing the package.json or the pwd if no package.json is found. E.g. This option allows comments in package.json. If the test path matches any of the patterns, it will not be transformed. Exemplu: ["/build/"]. A pattern that is matched against file paths to determine which folder contains manual mocks. Utilizaţi cuvântul cheie pentru a include calea către directorul rădăcină din proiectul vostru pentru a preveni ignorarea accidentală a fișierelor în medii diferite, care pot avea diferite directoare rădăcină. We recommend placing the extensions most commonly used in your project on the left, so if you are using TypeScript, you may want to consider moving "ts" and/or "tsx" to the beginning of the array. Note: A global teardown module configured in a project (using multi-project runner) will be triggered only when you run at least one test from this project. Oftentimes, you'll want to set this to 'src' or 'lib', corresponding to where in your repository the code is stored. În cazul în care calea unui modul se potriveşte cu oricare dintre modele, acesta nu va fi require()-uit în mediul de testare. // Use packageFilter to process parsed `package.json` before the resolution (see https://www.npmjs.com/package/resolve#resolveid-opts-cb), // Alter the value of `main` before resolving the package, // Example test path, used for preflight consistency check of the implementation above, // Will trigger if docblock contains @my-custom-pragma my-pragma-value. The relevant options depend on the environment. import * as React from "react"; import * as renderer from "react-test-renderer"; import { ChartTitle } from "Components/ That module can also contain a getCacheKey function to generate a cache key to determine if the logic has changed and any cached artifacts relying on it should be discarded. Read more about watch plugins here. O listă de tipare RegExp care sunt comparate cu toate căile fişierelor sursă înainte de a re-rula testele în modul de veghe. Deseori, veţi dori să setați această valoare la "src" sau "lib", corespunzător locației unde stocați codul sursă. invalid configuration). This code: Reads the JSON found in root/config.json file. Use the string token to include the path to your project's root directory. See also testMatch [array], but note that you cannot specify both options. See it in action at Exclude file(s) from Jest coverage using configuration on GitHub. By default it looks for .js and .jsx files Any docblock pragmas in test files will be passed to the environment constructor and can be used for per-test configuration. relay will replace all modules which contain relay as a substring in its name: relay, react-relay and graphql-relay will all be pointed to your stub. It will also find files called test.js or spec.js. Utilizaţi pentru a vă referi la valoarea rootDir, dacă doriţi să utilizaţi căi de fişier. If the test path matches any of the patterns, it will be skipped. Acesta va fi utilizat pentru a configura pragul minim de acoperire. To overcome this, you may use transformIgnorePatterns to allow transpiling such modules. For example, if you have tests in source files named with .t.js extension as following: You can collect coverage from those files with setting forceCoverageMatch. If you wanted to add even more jasmine plugins to the mix (or if you wanted some custom, project-wide matchers for example), you could do so in these modules. Aceste reguli sunt comparate față de calea completă. // Set reference to mongod in order to close the server during teardown. Use the string token to include the path to your project's root directory to prevent it from accidentally ignoring all of your files in different environments that may have different root directories. For example, if you wanted to be able to use a new language feature in your modules or tests that isn't yet supported by node, you might plug in one of many compilers that compile a future version of JavaScript to a current one. Additionally, you can substitute captured regex groups using numbered backreferences. Thresholds, when specified as a positive number are taken to be the minimum percentage required. If the field is empty, PyCharm looks for a package.json file with a jest key. If you require modules without specifying a file extension, these are the extensions Jest will look for. Babel has two parallel config file formats, which can be used together, or independently. These pattern strings match against the full path. Thresholds for globs are applied to all files matching the glob. 1. An array of file extensions your modules use. If you want to use it to compile JavaScript or Typescript, it has to be explicitly defined by adding {"\\. testPath: // https://github.com/facebook/jest/blob/6b8b1404a1d9254e7d5d90a8934087a9c9899dab/packages/jest-runner/src/types.ts#L17-L21, relative to the root directory of your project, Every remaining file combined has less than 50% coverage (. This will lead to any mocks having their fake implementations removed and restores their initial implementation. The preset loads configuration that tells jest to look for.ts files and a few other things. All errors will also still be shown on the bottom after execution. So, for example, if you want your setupFiles config entry to point at the env-setup.js file at the root of your project, you could set its value to ["/env-setup.js"]. (x)" ]). The search is performed in the file system upwards from the working directory. Indicates whether each individual test should be reported during the run. Utilizaţi această opţiune de configurare pentru a adăuga tipuri personalizate de raportări Jest. Jest attempts to scan your dependency tree once (up-front) and cache it in order to ease some of the filesystem raking that needs to happen while running tests. When using Jest, we can achieve this task in two flavours: A. Acest lucru este util pentru proiecte monolit sau atunci când se lucrează pe mai multe proiecte în acelaşi timp. This can be done programmatically using jest.resetModules(). You can retrieve Jest's default options to expand them if needed: This option tells Jest that all imported modules in your tests should be mocked automatically. // The platform to use as the default, e.g. This option allows you to use a custom sequencer instead of Jest's default. When a threshold is specified as a negative number it represents the maximum number of uncovered entities allowed. top level so Jest will know how to find your settings: When using the --config option, the JSON file must not contain a "jest" key: These options let you control Jest's behavior in your package.json file. **/node_modules/** or **/vendor/**. A list of paths to snapshot serializer modules Jest should use for snapshot testing. That is caused by backward compatibility reasons and process.on('unhandledRejection', callback) signature, but that usually should not be a problem for most of the use cases. Această opţiune de configurare vă permite să particularizaţi unde Jest stochează datele pe disc. The order in which the mappings are defined matters. For example, this preset foo-bar/jest-preset.js will be configured as follows: Presets may also be relative to filesystem paths. Examples of runners include: Note: The runner property value can omit the jest-runner- prefix of the package name. If the pragma is not present, it will not be present in the object. A list of paths to directories that Jest should use to search for tests in. Useful for easing the upgrade process. Sets environment config to corresponding environment node found in config.json based on NODE_ENV environment variable value (which itself defaults to development if null). Thresholds specified as a negative number represent the maximum number of uncovered entities allowed. If the file path matches any of the patterns, coverage information will be skipped. Code of Conduct • Report abuse. The pattern or patterns Jest uses to detect test files. Using enzyme with Jest Configure with Jest. Any istanbul reporter can be used. If any keys which are in .env.sample but not in the evironment used, it is immediately reported in console. The projects feature can also be used to run multiple configurations or multiple runners. An array of regexp pattern strings that are matched against all source file paths before transformation. The default is jasmine2. Note that if there is only one test file being run it will default to true. Since every test runs in its own environment, these scripts will be executed in the testing environment immediately before executing the test code itself. This is useful to isolate modules for every test so that the local module state doesn't conflict between tests. cfg/default ; And if the configuration menu depends on other configuration items, they are also downloaded. Acest lucru se poate face programatic folosind jest.resetModules(). If you are introducing Jest to a large organization with an existing codebase but few tests, enabling this option can be helpful to introduce unit tests gradually. Read more about Babel7 + preset-typescript vs TypeScript (and ts-jest). Example: ["/bower_components/", "/node_modules/"]. Any istanbul reporter can be used. Thresholds specified as a positive number are taken to be the minimum percentage required. environment: Environment, The path to a module that runs some code to configure or set up the testing framework before each test. For example, if you wanted to be able to use a new language feature in your modules or tests that aren't yet supported by node, you might plug in one of many compilers that compile a future version of JavaScript to a current one. This will be used to configure the behavior of jest-haste-map, Jest's internal file crawler/cache system. Since setupFiles executes before the test framework is installed in the environment, this script file presents you the opportunity of running some code immediately after the test framework has been installed in the environment. If the field is empty, IntelliJ IDEA looks for a package.json file with a jest key. Component.test.js or Component.spec.js). For example, if your class is stored in my-custom-environment.js in some subfolder of your project, then the annotation might looke like this: Note: TestEnvironment is sandboxed. To use my-serializer-module as a serializer, configuration would be as The default environment in Jest is a browser-like environment through jsdom. Utilizaţi cuvântul cheie pentru a include calea către directorul rădăcină din proiectul vostru pentru a preveni ignorarea accidentală a fișierelor în medii diferite, care pot avea diferite directoare rădăcină. If you wanted to add even more jasmine plugins to the mix (or if you wanted some custom, project-wide matchers for example), you could do so in this module. Jest's configuration can be defined in the `package.json` file of your project, or through a `jest.config.js` file or through the `--config ` option. De exemplu, dacă doriţi configurarea setupFiles să indice către fișierul env-setup.js din rădăcina proiectul vostru, puteți seta valoarea sa la ["/env-setup.js"]. If you are not using jest’s default configuration file naming convention (i.e. Create config.js in root/config folder like below. A custom test runner can be provided by specifying a path to a test runner implementation. For example, imagine we want to use the field "module" if it is present, otherwise fallback to "main": Automatically restore mock state before every test. An array of file extensions your modules use. E.g. : __mocks__/lodash.js). It is possible to override this setting in individual tests by explicitly calling jest.mock() at the top of the test file.

jest config file

Note: Node modules are automatically mocked when you have a manual mock in place (e.g. // Public methods of `utils` are now mock functions, // You can provide them with your own implementation, Lines : Unknown% ( 0/0 ) By default, each test file gets its own independent module registry. It's also worth noting that setupFiles will execute before setupFilesAfterEnv. Note: a transformer is only ran once per file unless the file has changed. Default: (/__tests__/.*|(\\.|/)(test|spec))\\.jsx?$. Contribute to aelbore/esbuild-jest development by creating an account on GitHub. An array of glob patterns Aceste tipare sunt comparate față de calea completă. An alternative API to setting the NODE_PATH env variable, modulePaths is an array of absolute paths to Note: Core modules, like fs, are not mocked by default. Allows for a label to be printed alongside a test while it is running. Deoarece fiecare test se execută în propriul său mediu, aceste module vor fi executate în mediul de testare imediat înainte de execuția codului de testare în sine. indicating a set of files for which coverage information should be collected. This option sets the URL for the jsdom environment. On Windows, it creates a new start menu entry on the first use and not display the notification. json to store Jest's config, the "jest" key should be used on the top level so Jest. Note: To use this, a sample env file .env.sampleshould be placed i… Patterns are checked one by one until one fits. Un set de variabile globale care trebuie să fie disponibile în toate mediile de testare. This function gets Jest's globalConfig object as a parameter. Sets the path to the prettier node module used to update inline snapshots. Placing your files in the folder above will work every single time. Setting this value to fake allows the use of fake timers for functions such as setTimeout. relay will replace all modules which contain relay as a substring in its name: relay, react-relay and graphql-relay will all be pointed to your stub. File-relative configuration 1. Directorul unde Jest ar trebui să salveze fişierele sale de acoperire. Note: if you are using the babel-jest transformer and want to use an additional code preprocessor, keep in mind that when "transform" is overwritten in any way the babel-jest is not loaded automatically anymore. If you'd like to use your `package.json` to store Jest's config, the `"jest"` key should be used on the top level so Jest will know how to find your settings: The most specific rule should be listed first. (default: [ "**/__tests__/**/*.[jt]s? A transformer is a module that provides a synchronous function for transforming source files. În cazul în care dezvoltați un serviciu nodejs, utilizaţi opţiunea node pentru a folosi un mediu similar cu nodejs. The pattern Jest uses to detect test files. You can pass configuration to a transformer like {filePattern: ['path-to-transformer', {options}]} For example, to configure babel-jest for non-default behavior, {"\\.js$": ['babel-jest', {rootMode: "upward"}]}. Item Description; Configuration file : In this field, optionally specify the jest.config file to use: select the relevant file from the list, or click and select it in the dialog that opens, or just type the path in the field. The search is performed in the file system upwards from the working directory. În plus, puteţi înlocui grupuri capturate cu regex folosind referințe numerotate. If a given module's path matches any of the patterns, it will not be require()-able in the test environment. : The extract function should return an iterable (Array, Set, etc.) ts-jest. All errors will also still be shown on the bottom after execution. By adding a @jest-environment docblock at the top of the file, you can specify another environment to be used for all tests in that file: Puteţi crea propriile module care vor fi folosite pentru configurarea mediul de testare. Notes. 'my-custom-reporter.js reported an error'. By default it looks for .js, .jsx, .ts and .tsx files inside of __tests__ folders, as well as any files with a suffix of .test or .spec (e.g. Each test suite will trigger setup/teardown in their own TestEnvironment. Any test above this limit will be queued and executed once a slot is released. By default, Jest runs all tests and produces all errors into the console upon completion. See the micromatch package for details of the patterns you can specify. with the dependencies found in the code. Atunci când configuraţia projects este completată cu o serie de căi sau tipare glob, Jest va rula testele în toate proiectele specificate, în acelaşi timp. Notifications will be properly displayed on subsequent runs. This option allows you to use custom watch plugins. If you'd like to use If you want a path to be relative to the root directory of your project, please include inside a path's string, like "/a-configs-folder". JEST_JUNIT_ADD_FILE_ATTRIBUTE: addFileAttribute: Add file attribute to the output.

The relevant options depend on the environment. import * as React from "react"; import * as renderer from "react-test-renderer"; import { ChartTitle } from "Components/ That module can also contain a getCacheKey function to generate a cache key to determine if the logic has changed and any cached artifacts relying on it should be discarded. Read more about watch plugins here. O listă de tipare RegExp care sunt comparate cu toate căile fişierelor sursă înainte de a re-rula testele în modul de veghe. Deseori, veţi dori să setați această valoare la "src" sau "lib", corespunzător locației unde stocați codul sursă. invalid configuration). This code: Reads the JSON found in root/config.json file. Use the string token to include the path to your project's root directory. See also testMatch [array], but note that you cannot specify both options. See it in action at Exclude file(s) from Jest coverage using configuration on GitHub. By default it looks for .js and .jsx files Any docblock pragmas in test files will be passed to the environment constructor and can be used for per-test configuration. relay will replace all modules which contain relay as a substring in its name: relay, react-relay and graphql-relay will all be pointed to your stub. It will also find files called test.js or spec.js. Utilizaţi pentru a vă referi la valoarea rootDir, dacă doriţi să utilizaţi căi de fişier. If the test path matches any of the patterns, it will be skipped. Acesta va fi utilizat pentru a configura pragul minim de acoperire. To overcome this, you may use transformIgnorePatterns to allow transpiling such modules. For example, if you have tests in source files named with .t.js extension as following: You can collect coverage from those files with setting forceCoverageMatch. If you wanted to add even more jasmine plugins to the mix (or if you wanted some custom, project-wide matchers for example), you could do so in these modules. Aceste reguli sunt comparate față de calea completă. // Set reference to mongod in order to close the server during teardown. Use the string token to include the path to your project's root directory to prevent it from accidentally ignoring all of your files in different environments that may have different root directories. For example, if you wanted to be able to use a new language feature in your modules or tests that isn't yet supported by node, you might plug in one of many compilers that compile a future version of JavaScript to a current one. Additionally, you can substitute captured regex groups using numbered backreferences. Thresholds, when specified as a positive number are taken to be the minimum percentage required. If the field is empty, PyCharm looks for a package.json file with a jest key. If you require modules without specifying a file extension, these are the extensions Jest will look for. Babel has two parallel config file formats, which can be used together, or independently. These pattern strings match against the full path. Thresholds for globs are applied to all files matching the glob. 1. An array of file extensions your modules use. If you want to use it to compile JavaScript or Typescript, it has to be explicitly defined by adding {"\\. testPath: // https://github.com/facebook/jest/blob/6b8b1404a1d9254e7d5d90a8934087a9c9899dab/packages/jest-runner/src/types.ts#L17-L21, relative to the root directory of your project, Every remaining file combined has less than 50% coverage (. This will lead to any mocks having their fake implementations removed and restores their initial implementation. The preset loads configuration that tells jest to look for.ts files and a few other things. All errors will also still be shown on the bottom after execution. So, for example, if you want your setupFiles config entry to point at the env-setup.js file at the root of your project, you could set its value to ["/env-setup.js"]. (x)" ]). The search is performed in the file system upwards from the working directory. Indicates whether each individual test should be reported during the run. Utilizaţi această opţiune de configurare pentru a adăuga tipuri personalizate de raportări Jest. Jest attempts to scan your dependency tree once (up-front) and cache it in order to ease some of the filesystem raking that needs to happen while running tests. When using Jest, we can achieve this task in two flavours: A. Acest lucru este util pentru proiecte monolit sau atunci când se lucrează pe mai multe proiecte în acelaşi timp. This can be done programmatically using jest.resetModules(). You can retrieve Jest's default options to expand them if needed: This option tells Jest that all imported modules in your tests should be mocked automatically. // The platform to use as the default, e.g. This option allows you to use a custom sequencer instead of Jest's default. When a threshold is specified as a negative number it represents the maximum number of uncovered entities allowed. top level so Jest will know how to find your settings: When using the --config option, the JSON file must not contain a "jest" key: These options let you control Jest's behavior in your package.json file. **/node_modules/** or **/vendor/**. A list of paths to snapshot serializer modules Jest should use for snapshot testing. That is caused by backward compatibility reasons and process.on('unhandledRejection', callback) signature, but that usually should not be a problem for most of the use cases. Această opţiune de configurare vă permite să particularizaţi unde Jest stochează datele pe disc. The order in which the mappings are defined matters. For example, this preset foo-bar/jest-preset.js will be configured as follows: Presets may also be relative to filesystem paths. Examples of runners include: Note: The runner property value can omit the jest-runner- prefix of the package name. If the pragma is not present, it will not be present in the object. A list of paths to directories that Jest should use to search for tests in. Useful for easing the upgrade process. Sets environment config to corresponding environment node found in config.json based on NODE_ENV environment variable value (which itself defaults to development if null). Thresholds specified as a negative number represent the maximum number of uncovered entities allowed. If the file path matches any of the patterns, coverage information will be skipped. Code of Conduct • Report abuse. The pattern or patterns Jest uses to detect test files. Using enzyme with Jest Configure with Jest. Any istanbul reporter can be used. If any keys which are in .env.sample but not in the evironment used, it is immediately reported in console. The projects feature can also be used to run multiple configurations or multiple runners. An array of regexp pattern strings that are matched against all source file paths before transformation. The default is jasmine2. Note that if there is only one test file being run it will default to true. Since every test runs in its own environment, these scripts will be executed in the testing environment immediately before executing the test code itself. This is useful to isolate modules for every test so that the local module state doesn't conflict between tests. cfg/default ; And if the configuration menu depends on other configuration items, they are also downloaded. Acest lucru se poate face programatic folosind jest.resetModules(). If you are introducing Jest to a large organization with an existing codebase but few tests, enabling this option can be helpful to introduce unit tests gradually. Read more about Babel7 + preset-typescript vs TypeScript (and ts-jest). Example: ["/bower_components/", "/node_modules/"]. Any istanbul reporter can be used. Thresholds specified as a positive number are taken to be the minimum percentage required. environment: Environment, The path to a module that runs some code to configure or set up the testing framework before each test. For example, if you wanted to be able to use a new language feature in your modules or tests that aren't yet supported by node, you might plug in one of many compilers that compile a future version of JavaScript to a current one. This will be used to configure the behavior of jest-haste-map, Jest's internal file crawler/cache system. Since setupFiles executes before the test framework is installed in the environment, this script file presents you the opportunity of running some code immediately after the test framework has been installed in the environment. If the field is empty, IntelliJ IDEA looks for a package.json file with a jest key. Component.test.js or Component.spec.js). For example, if your class is stored in my-custom-environment.js in some subfolder of your project, then the annotation might looke like this: Note: TestEnvironment is sandboxed. To use my-serializer-module as a serializer, configuration would be as The default environment in Jest is a browser-like environment through jsdom. Utilizaţi cuvântul cheie pentru a include calea către directorul rădăcină din proiectul vostru pentru a preveni ignorarea accidentală a fișierelor în medii diferite, care pot avea diferite directoare rădăcină. If you wanted to add even more jasmine plugins to the mix (or if you wanted some custom, project-wide matchers for example), you could do so in this module. Jest's configuration can be defined in the `package.json` file of your project, or through a `jest.config.js` file or through the `--config ` option. De exemplu, dacă doriţi configurarea setupFiles să indice către fișierul env-setup.js din rădăcina proiectul vostru, puteți seta valoarea sa la ["/env-setup.js"]. If you are not using jest’s default configuration file naming convention (i.e. Create config.js in root/config folder like below. A custom test runner can be provided by specifying a path to a test runner implementation. For example, imagine we want to use the field "module" if it is present, otherwise fallback to "main": Automatically restore mock state before every test. An array of file extensions your modules use. E.g. : __mocks__/lodash.js). It is possible to override this setting in individual tests by explicitly calling jest.mock() at the top of the test file.
