v1.0.0-beta.0

This is a beta release for upcoming 1.0.0 version. Use beta dist-tag when installing Vitest: npm install --save-dev vitest@beta.

   🚨 Breaking Changes

• Support multiple parallel child_process  -  by @AriPerkkio in #3925 (8b4a4)
  • If you have to disable threads (if you use canvas package, for example), this should improve your speed tremendously.
  • useFakeTimers() no longer automatically mocks process.nextTick. Users can still mock it by explicitly specifying useFakeTimers({ toFake: ['nextTick'] })
• Add support for pool and poolOptions, remove old flags  -  by @AriPerkkio in #4172 (114a9)
  • This removes a lot of configuration options to make it easier to configure the runner to your needs. Please, have a look at migration examples if you rely on --threads or other related flags.
    • --threads is now --pool=threads
    • --no-threads is now --pool=forks
    • --single-thread is now --poolOptions.threads.singleThread
    • --experimental-vm-threads is now --pool=vmThreads
    • --experimental-vm-worker-memory-limit is now --poolOptions.vmThreads.memoryLimit
    • --isolate is now --poolOptions.<pool-name>.isolate and browser.isolate
    • test.maxThreads is now test.poolOptions.<pool-name>.maxThreads
    • test.minThreads is now test.poolOptions.<pool-name>.minThreads
    • test.useAtomics is now test.poolOptions.<pool-name>.useAtomics
    • test.poolMatchGlobs.child_process is now test.poolMatchGlobs.forks
    • test.poolMatchGlobs.experimentalVmThreads is now test.poolMatchGlobs.vmThreads
• Make snapshots more visually pleasing by @sheremet-va in #3961
  • This will probably cause a lot of test mismatches. Quotes in snapshots are no longer escaped, and all snapshots use backtick quotes (`) even if the string is just a single line. Please, read the PR description for a way to use the previous behavior if you have problems upgrading.
• runner: Correctly process custom tasks, update runner hooks naming by @sheremet-va in #4076
  • This PR updates the names for most of the methods on a custom runner (Test -> Task).
  • It also improves the flow for creating your custom tasks like benchmarks using createTaskCollector utility. This is primarily an advanced API for library authors.
  • If you use @vitest/snapshot separately, you will also need to update its usage. You no longer need to extend SnapshotClient to override equalityCheck method - just pass it down as an isEqual option. Also some of the public API methods were renamed for clarity.
  • If you have any questions, please, read the PR description first.
