   🚨 Breaking Changes

• Throw an error, if the module cannot be resolved  -  by @​sheremet-va in https://github.com/vitest-dev/vitest/issues/3307 (1ad63)
  • Vitest used to fall back to the original import when it could not resolve it to the file path or the virtual module. This leads to hard-to-find module graph mismatches if you had incorrect alias or relied on relative imports to be resolved to the project root (which is usual behavior in TypeScript) because the code accidentally "worked". With this release, Vitest will now throw an error if it cannot resolve the module - there are possible edge cases that are not covered yet, so if you have any problems with this, please open a separate issue with reproduction.
• Improve globs  -  by @​nickmccurdy in https://github.com/vitest-dev/vitest/issues/3392 (19ecc)
  • Vitest now has glob patterns similar to Jest for better compatibility. It's possible that some files will be considered test files when previously they were not. For example, Vitest now considers test.js to be a test file. Also any file in __tests__ is now considered to be a test, not just files with test or spec suffix.
• Add @vitest/coverage-v8 package  -  by @​AriPerkkio in https://github.com/vitest-dev/vitest/issues/3339 (82112)
  • Vitest now uses v8 code coverage directly for better performance. @vitest/coverage-c8 is deprecated as Vitest no longer uses c8 package for coverage output. It will not be updated anymore, and Vitest will fail in the next version if the user has c8 as their coverage provider. Please, install the new @vitest/coverage-v8 package if you previously used @vitest/coverage-c8.
• mocker: Don't restore mock to the original if the module is automocked  -  by @​sheremet-va in https://github.com/vitest-dev/vitest/issues/3518 (c1004)
  • spy.mockRestore on auto-mocked named exports will no longer restore their implementation to the actual function. This behavior better matches what Jest does.

   🚨 Breaking Changes

• Remove browser from allowed pools inside poolMatchGlob config option. Please, use Vitest workspaces for running tests in the browser.

• Move assertion declarations to expect package  -  by @​sheremet-va in https://github.com/vitest-dev/vitest/issues/3294 (cf3af)

  • The change should be minor:

  - declare namespace Vi {
  + declare module 'vitest' {
     interface Assertion<T = any> extends CustomMatchers<T> {}
     interface AsymmetricMatchersContaining extends CustomMatchers {}
  }

   🚀 Features

• Update mock implementation to support ESM runtime, introduce "vi.hoisted"  -  by @​sheremet-va in https://github.com/vitest-dev/vitest/issues/3258 (0c09a)
  • Bypass ESM import order restriction with vi.hoisted to run code before imports are executed:

  vi.hoisted(() => vi.setSystemTime(new Date(2022, 1, 1)))

  You can also use it to pass variables to vi.mock:

  const { mockedMethod } = vi.hoisted(() => {
    return { mockedMethod: vi.fn() }
  })   
  vi.mock('./path/to/module.js', () => {
    return { originalMethod: mockedMethod }
  })

This release makes some significant changes to how tests are running. If you were using --no-threads before, you might consider enabling --single-thread instead (because your tests are now running in child_process instead of a worker thread) or try our new performance optimization feature (discussed later). If you were relying on API that was not available inside a worker (like process.chdir(), you can now use this option.

One of the potential breaking bug fixes is that environments do not share the same global scope anymore if you run them with --no-isolate, --no-threads or --single-thread - you might need to update your setup files if you were relying on a global variable before.

If you had performance issues on large code bases before, try the new deps.experimentalOptimizer option instead of disabling threads. Feedback is welcome!

One of the breaking changes includes adding a link to snapshots inside snapshot files, meaning you will need to update all your snapshots.

   🚨 Breaking Changes

• Vitest as peer dependency for coverage packages  -  by @​AriPerkkio in https://github.com/vitest-dev/vitest/issues/2836 (94247)
• Coverage-c8 to use V8 profiler directly instead of NODE_V8_COVERAGE  -  by @​AriPerkkio in https://github.com/vitest-dev/vitest/issues/2786 (095c6)
• Add a link to the comment at the top of the snapshot file  -  by @​btea in https://github.com/vitest-dev/vitest/issues/2867 (615e1)
• Always run separate environments in isolation  -  by @​sheremet-va in https://github.com/vitest-dev/vitest/issues/2860 (1f858)
  • Tests with node and jsdom (and other environments) now don't share the same global scope, if you run them with --no-isolate or --no-threads flag. Vitest doesn't provide a way to restore the previous behavior as it is considered a bug.
• Use child_process when --no-threads is used  -  by @​sheremet-va in https://github.com/vitest-dev/vitest/issues/2772 (7bf54)
  • Tests inside chid_process might run longer due to the communication overhead. If you want to restore the previous behavior, use --single-thread.
