jest config file

If you are using TypeScript this should be ["js", "jsx", "json", "ts", "tsx"], An array of directory names to be searched recursively up from the requiring module's location. If you are building a node service, you can use the node option to use a node-like environment instead. An array of regexp pattern strings that are matched against all test paths before executing the test. Jest încearcă să scaneze arborele de dependenţe o dată şi îl memorează pentru a ușura lucrul cu sistemul de fişiere care trebuie să se întâmple în timp ce rulează teste. This function gets Jest's globalConfig object as a parameter. 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. A list of reporter names that Jest uses when writing coverage reports. [jt]sx?$": "babel-jest"} to the transform property. Indicates which provider should be used to instrument code for coverage. Exemplu: ["/node_modules/"]. This function gets Jest's globalConfig object as a parameter. If the test path matches any of the patterns, it will be skipped. Any istanbul reporter can be used. By default it looks for .js and .jsx files For example, Jest ships with several plug-ins to jasmine that work by monkey-patching the jasmine API. statements: -10 implies that no more than 10 uncovered statements are allowed. Make calling deprecated APIs throw helpful error messages. If you want to use it to compile JavaScript code it has to be explicitly defined. An array of glob patterns ... /node_modules/ and our 2 project config files (add/remove more exclusions to this list to match your Expo app needs). Use it in your Jest config file like this: Default timeout of a test in milliseconds. config: ProjectConfig, Utilizaţi pentru a vă referi la valoarea rootDir, dacă doriţi să utilizaţi căi de fişier. Fake timers are useful when a piece of code sets a long timeout that we don't want to wait for in a test. To overcome this, you may use transformIgnorePatterns to allow transpiling such modules. Additionally, you can substitute captured regex groups using numbered backreferences. babel.config.js We use babel-jest for ts transpilation, and so I had to figure out a way to let babel use the babelrc files in individual project directories. Note: a transformer is only run once per file unless the file has changed. Component.test.js or Component.spec.js). 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. If the value is modern, @sinonjs/fake-timers will be used as implementation instead of Jest's own legacy implementation. If the test path matches any of the patterns, it will not be transformed. A number limiting the number of tests that are allowed to run at the same time when using test.concurrent. Each setupFile will be run once per test file. On Windows, it creates a new start menu entry on the first use and not display the notification. This is useful to isolate modules for every test so that the local module state doesn't conflict between tests. This visually tells which project a test belongs to. Normally, jest-circus test runner would pause until a promise returned from handleTestEvent gets fulfilled, except for the next events: start_describe_definition, finish_describe_definition, add_hook, add_test or error (for the up-to-date list you can look at SyncEvent type in the types definitions). 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 will collect coverage information for all the files inside the project's rootDir, except the ones that match An alternative API to setting the NODE_PATH env variable, modulePaths is an array of absolute paths to additional locations to search when resolving modules. Add "text" or "text-summary" to see a coverage summary in the console output. Directorul unde Jest ar trebui să salveze fişierele sale de acoperire. For example, you can override options given to jsdom such as {userAgent: "Agent/007"}. Here are sample valid values. Using enzyme with Jest Configure with Jest. 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. 1. All errors will also still be shown on the bottom after execution. De exemplu, Jest este livrat cu mai multe plug-in-uri jasmine, care modifică API-ul jasmine. An array of regexp pattern strings that are matched against all modules before the module loader will automatically return a mock for them. Examples of runners include: Note: The runner property value can omit the jest-runner- prefix of the package name. Setting this option will override the default, if you wish to still search node_modules for packages include it along with any other options: ["node_modules", "bower_components"], Default: ["js", "json", "jsx", "ts", "tsx", "node"]. 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. We've told Jest to ignore files matching a stylesheet or image extension, and instead, require our mock files. // Whether to throw on error on module collision. Note that using v8 is considered experimental. An array of regexp pattern strings that are matched against all source file paths before transformation. Thresholds, when specified as a positive number are taken to be the minimum percentage required. Component.test.js or Component.spec.js). Este posibilă suprascrierea aceastei setări în teste individuale prin apelul explicit jest.mock() în partea de sus a fişierului de testare. Indicates whether each individual test should be reported during the run. 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. Thresholds specified as a positive number are taken to be the minimum percentage required. A list of paths to snapshot serializer modules Jest should use for snapshot Modules that are mapped to an alias are unmocked by default, regardless of whether automocking is enabled or not. 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. If you set this to false, you should import from @jest/globals, e.g. jest.config.js is not shown in the file tree. Jest's configuration can be defined in the package.json file of your project 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. This is useful for some commonly used 'utility' modules that are almost always used as implementation details almost all the time (like underscore/lo-dash, etc). This can be done programmatically using jest.resetModules(). 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 (. Exemplu: ["/build/"]. For example, to run both tests and ESLint (via jest-runner-eslint) in the same invocation of Jest: Note: When using multi-project runner, it's recommended to add a displayName for each project. (default: [ "**/__tests__/**/*.[jt]s? Sets the path to the prettier node module used to update inline snapshots. By default safe is set to false. We can use istanbul pragmas to ignore files using the following comment at the top of any file: 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. The path to a module that can resolve test<->snapshot path. They can be mocked explicitly, like jest.mock('fs'). All errors will also still be shown on the bottom after execution. Un astfel de modul trebuie să exporte o funcţie cu următoarea semnătură: Un exemplu de astfel de funcţie poate fi găsită în modulul nostru implicit jasmine2. If a file matches Modele glob pe care Jest le utilizează pentru a detecta fişiere de test. will override the default, if you wish to still search node_modules for packages include it Each test suite will trigger setup/teardown in their own TestEnvironment. Note: A global setup module configured in a project (using multi-project runner) will be triggered only when you run at least one test from this project. E.g. (e.g. In line with k3s, it is fairly straightforward.
