+
+## Vite 8 Support
+
+This release adds support for the new Vite 8 version. Additionally, Vitest now uses the installed `vite` version instead of downloading a separate dependency, if possible. This makes issues like type inconsistencies in your config file obsolete.
+
+## Test Tags
+
+[Tags](/guide/test-tags) let you label tests to organize them into groups. Once tagged, you can filter tests by tag or apply shared options - like a longer timeout or automatic retries - to every test with a given tag.
+
+To use tags, define them in your configuration file. Each tag requires a `name` and can optionally include test options that apply to every test marked with that tag. For the full list of available options, see [`tags`](/config/tags).
+
+```ts [vitest.config.js]
+import { defineConfig } from 'vitest/config'
+
+export default defineConfig({
+ test: {
+ tags: [
+ {
+ name: 'db',
+ description: 'Tests for database queries.',
+ timeout: 60_000,
+ },
+ {
+ name: 'flaky',
+ description: 'Flaky CI tests.',
+ retry: process.env.CI ? 3 : 0,
+ },
+ ],
+ },
+})
+```
+
+With this configuration, you can apply `flaky` and `db` tags to your tests:
+
+```ts
+test('flaky database test', { tags: ['flaky', 'db'] }, () => {
+ // ...
+})
+```
+
+The test has a timeout of 60 seconds and will be retried 3 times on CI because these options were specified in the configuration file for `db` and `flaky` tags.
+
+Inspired by [pytest](https://docs.pytest.org/en/stable/reference/reference.html#cmdoption-m), Vitest supports a custom syntax for filtering tags:
+
+- `and` or `&&` to include both expressions
+- `or` or `||` to include at least one expression
+- `not` or `!` to exclude the expression
+- `*` to match any number of characters (0 or more)
+- `()` to group expressions and override precedence
+
+Here are some common filtering patterns:
+
+```shell
+# Run only unit tests
+vitest --tags-filter="unit"
+
+# Run tests that are both frontend AND fast
+vitest --tags-filter="frontend and fast"
+
+# Run frontend tests that are not flaky
+vitest --tags-filter="frontend && !flaky"
+
+# Run tests matching a wildcard pattern
+vitest --tags-filter="api/*"
+```
+
+## Experimental `viteModuleRunner: false`
+
+By default, Vitest runs all code inside Vite's [module runner](https://vite.dev/guide/api-environment-runtimes#modulerunner) — a permissive sandbox that provides `import.meta.env`, `require`, `__dirname`, `__filename`, and applies Vite plugins and aliases. While this makes getting started easy, it can hide real issues: your tests may pass in the sandbox but fail in production because the runtime behavior differs from native Node.js.
+
+Vitest 4.1 introduces [`experimental.viteModuleRunner`](/config/experimental#experimental-vitemodulerunner), which lets you disable the module runner entirely and run tests with native `import` instead:
+
+```ts [vitest.config.ts]
+import { defineConfig } from 'vitest/config'
+
+export default defineConfig({
+ test: {
+ experimental: {
+ viteModuleRunner: false,
+ },
+ },
+})
+```
+
+With this flag, **no file transforms are applied** — your test files, source code, and setup files are executed by Node.js directly. This means faster startup, closer-to-production behavior, and issues like incorrect `__dirname` injection or silently passing imports of nonexistent exports are caught early.
+
+If you are using Node.js 22.18+ or 23.6+, TypeScript is [stripped natively](https://nodejs.org/en/learn/typescript/run-natively) — no extra configuration needed.
+
+Mocking with `vi.mock` and `vi.hoisted` is supported via the Node.js [Module Loader API](https://nodejs.org/api/module.html#customization-hooks) (requires Node.js 22.15+). Note that `import.meta.env`, Vite plugins, aliases, and the `istanbul` coverage provider are not available in this mode.
+
+Consider this option if you run server-side or script-like tests that don't need Vite transforms. For `jsdom`/`happy-dom` tests, we still recommend the default module runner or [browser mode](/guide/browser/).
+
+Read more in the [`experimental.viteModuleRunner` docs](/config/experimental#experimental-vitemodulerunner).
+
+## Configure UI Browser Window
+
+Vitest 4.1 introduces [`browser.detailsPanelPosition`](/config/browser/detailspanelposition), letting you choose where the details panel appears in Browser UI.
+
+
+ 
+ 
+
+ An example of UI with the details panel at the bottom.
+
+
+This is especially useful on smaller screens, where switching to a bottom panel leaves more horizontal space for your app:
+
+```ts [vitest.config.ts]
+import { defineConfig } from 'vitest/config'
+
+export default defineConfig({
+ test: {
+ browser: {
+ enabled: true,
+ detailsPanelPosition: 'bottom', // or 'right'
+ },
+ },
+})
+```
+
+You can also switch this directly from the UI via the new layout toggle button.
+
+## Enhanced Browser Trace View
+
+Vitest 4.1 brings major improvements to the [Playwright Trace Viewer](/guide/browser/trace-view) integration in browser mode. Browser interactions like `click`, `fill`, and `expect.element` are now automatically grouped in the trace timeline and linked back to the exact line in your test file.
+
+
+ 
+ 
+
+ An example of trace view with `expect.element` assertion failure highlighted.
+
+
+Framework libraries are also integrating with the trace. For example, [`vitest-browser-react`](https://github.com/vitest-community/vitest-browser-react)'s `render()` utility now automatically appears in the trace with rendered element highlighted.
+
+For custom annotations, the new [`page.mark`](/api/browser/context#mark) and [`locator.mark`](/api/browser/locators#mark) APIs let you add your own markers to the trace:
+
+```ts
+import { page } from 'vitest/browser'
+
+await page.mark('before sign in')
+await page.getByRole('button', { name: 'Sign in' }).click()
+await page.mark('after sign in')
+```
+
+You can also group a whole flow under one named entry:
+
+```ts
+await page.mark('sign in flow', async () => {
+ await page.getByRole('textbox', { name: 'Email' }).fill('john@example.com')
+ await page.getByRole('textbox', { name: 'Password' }).fill('secret')
+ await page.getByRole('button', { name: 'Sign in' }).click()
+})
+```
+
+Read more in the [Trace View guide](/guide/browser/trace-view).
+
+## Type-Inference in `test.extend` - New Builder Pattern
+
+Vitest 4.1 introduces a new [`test.extend`](/guide/test-context) pattern that supports type inference. You can return a value from the factory instead of calling the `use` function - TypeScript infers the type of each fixture from its return value, so you don't need to declare types manually.
+
+```ts
+import { test as baseTest } from 'vitest'
+
+export const test = baseTest
+ // Simple value - type is inferred as { port: number; host: string }
+ .extend('config', { port: 3000, host: 'localhost' })
+ // Function fixture - type is inferred from return value
+ .extend('server', async ({ config }) => {
+ // TypeScript knows config is { port: number; host: string }
+ return `http://${config.host}:${config.port}`
+ })
+```
+
+For fixtures that need setup or cleanup logic, use a function. The `onCleanup` callback registers teardown logic that runs after the fixture's scope ends:
+
+```ts
+import { test as baseTest } from 'vitest'
+
+export const test = baseTest
+ .extend('tempFile', async ({}, { onCleanup }) => {
+ const filePath = `/tmp/test-${Date.now()}.txt`
+ await fs.writeFile(filePath, 'test data')
+
+ // Register cleanup - runs after test completes
+ onCleanup(() => fs.unlink(filePath))
+
+ return filePath
+ })
+```
+
+In addition to this, Vitest now passes down `file` and `worker` contexts to `beforeAll`, `afterAll` and `aroundAll` hooks:
+
+```ts
+import { test as baseTest } from 'vitest'
+
+const test = baseTest
+ .extend('config', { scope: 'file' }, () => loadConfig())
+ .extend('db', { scope: 'file' }, ({ config }) => createDatabase(config.port))
+
+test.beforeAll(async ({ db }) => {
+ await db.migrateUsers()
+})
+
+test.afterAll(async ({ db }) => {
+ await db.deleteUsers()
+})
+```
+
+::: warning
+This change could be considered breaking - previously Vitest passed down undocumented `Suite` as the first argument. The team decided that the usage was small enough to not disrupt the ecosystem.
+:::
+
+## New `aroundAll` and `aroundEach` Hooks
+
+The new `aroundEach` hook registers a callback function that wraps around each test within the current suite. The callback receives a `runTest` function that **must** be called to run the test. The `aroundAll` hook works similarly, but is called for every suite, not every test.
+
+You should use `aroundEach` when your test needs to run **inside a context** that wraps around it, such as:
+- Wrapping tests in [AsyncLocalStorage](https://nodejs.org/api/async_context.html#class-asynclocalstorage) context
+- Wrapping tests with tracing spans
+- Database transactions
+
+```ts
+import { test as baseTest } from 'vitest'
+
+const test = baseTest
+ .extend('db', async ({}, { onCleanup }) => {
+ // db is created before `aroundEach` hook
+ const db = await createTestDatabase()
+ onCleanup(() => db.close())
+ return db
+ })
+
+test.aroundEach(async (runTest, { db }) => {
+ await db.transaction(runTest)
+})
+
+test('insert user', async ({ db }) => {
+ // called inside a transaction
+ await db.insert({ name: 'Alice' })
+})
+```
+
+## Helper for Better Stack Traces
+
+When a test fails inside a shared utility function, the stack trace usually points to the line inside that helper - not where it was called. This makes it harder to find which test actually failed, especially when the same helper is used across many tests.
+
+[`vi.defineHelper`](/api/vi#vi-definehelper) wraps a function so that Vitest removes its internals from the stack trace and points the error back to the call site instead:
+
+```ts
+import { expect, test, vi } from 'vitest'
+
+const assertPair = vi.defineHelper((a, b) => {
+ expect(a).toEqual(b) // 🙅♂️ error code block will NOT point to here
+})
+
+test('example', () => {
+ assertPair('left', 'right') // 🙆 but point to here
+})
+```
+
+This is especially useful for custom assertion libraries and reusable test utilities where the call site is more meaningful than the implementation.
+
+## `--detect-async-leaks` to Catch Leaks
+
+Leaked timers, handles, and unresolved async resources can make test suites flaky and hard to debug. Vitest 4.1 adds [`detectAsyncLeaks`](/config/detectasyncleaks) to help track these issues.
+
+You can enable it via CLI:
+
+```sh
+vitest --detect-async-leaks
+```
+
+Or in config:
+
+```ts [vitest.config.ts]
+import { defineConfig } from 'vitest/config'
+
+export default defineConfig({
+ test: {
+ detectAsyncLeaks: true,
+ },
+})
+```
+
+When enabled, Vitest uses `node:async_hooks` to report leaked async resources with source locations. Since this adds runtime overhead, it is best used while debugging.
+
+## `vscode` Improvements
+
+The official [vscode extension](https://vitest.dev/vscode) received a large number of fixes and new features:
+
+- The extension no longer keeps a running process in the background unless you explicitly enable continuous run manually or via a new config option `watchOnStartup`. This reduces memory usage and eliminates the `maximumConfigs` config option.
+- The new "Run Related Tests" command runs tests that import the currently open file.
+- The new "Toggle Continuous Run" action is now available when clicking on the gutter icon.
+- The extension now supports [Deno runtime](https://deno.com/).
+- The extension cancels the test run sooner after clicking "Stop", when possible.
+- The extension displays the module load time inline next to each import statement, if you are using Vitest 4.1.
+
+
+ 
+ An example of import breakdown in vscode.
+
+
+## GitHub Actions Job Summary
+
+The built-in [`github-actions` reporter](/guide/reporters#github-actions-reporter) now automatically generates a [Job Summary](https://github.blog/news-insights/product-news/supercharging-github-actions-with-job-summaries/) with an overview of your test results. The summary includes test file and test case statistics, and highlights flaky tests that required retries — with permalink URLs linking test names directly to the relevant source lines on GitHub.
+
+
+ 
+ 
+
+ An example of the job summary with flaky test details.
+
+
+The summary is enabled by default when running in GitHub Actions and writes to the path specified by `$GITHUB_STEP_SUMMARY`. No configuration is needed in most cases. To disable it or customize the output path:
+
+```ts [vitest.config.ts]
+import { defineConfig } from 'vitest/config'
+
+export default defineConfig({
+ test: {
+ reporters: [
+ ['github-actions', {
+ jobSummary: {
+ enabled: false, // or set `outputPath` to customize where the summary is written
+ },
+ }],
+ ],
+ },
+})
+```
+
+## New `agent` Reporter to Reduce Token Usage
+
+As AI coding agents become a common way to run tests, Vitest 4.1 introduces the [`agent` reporter](/guide/reporters#agent-reporter) — a minimal output mode designed to reduce token usage. It only displays failed tests and their errors, suppressing passed test output and console logs from passing tests.
+
+Vitest automatically enables this reporter when it detects it's running inside an AI coding agent. The detection is powered by [`std-env`](https://github.com/unjs/std-env), which recognizes popular agent environments out of the box. You can also set the `AI_AGENT=copilot` (or any name) environment variable explicitly. No configuration needed — just run Vitest as usual:
+
+```sh
+AI_AGENT=copilot vitest
+```
+
+If you configure custom reporters, the automatic detection is skipped, so add `'agent'` to the list manually if you want both.
+
+## New `mockThrow` API
+
+Previously, making a mock throw required wrapping the error in a function: `mockImplementation(() => { throw new Error(...) })`. The new [`mockThrow`](/api/mock#mockthrow) and [`mockThrowOnce`](/api/mock#mockthrowonce) methods make this more concise and readable:
+
+```ts
+const myMockFn = vi.fn()
+myMockFn.mockThrow(new Error('error message'))
+myMockFn() // throws Error<'error message'>
+```
+
+## Strict Mode in WebdriverIO and Preview
+
+Locating elements is now strict by default in `webdriverio` and `preview`, matching Playwright behavior.
+
+If a locator resolves to multiple elements, Vitest throws a "strict mode violation" instead of silently picking one. This helps catch ambiguous queries early:
+
+```ts
+const button = page.getByRole('button')
+
+await button.click() // throws if multiple buttons match
+await button.click({ strict: false }) // opt out and return first match
+```
+
+## Chai-style Mocking Assertions
+
+Vitest already supports chai-style assertions like `eql`, `throw`, and `be`. This release extends that support to mock assertions, making it easier to migrate from Sinon-based test suites without rewriting every expectation:
+
+```ts
+import { expect, vi } from 'vitest'
+
+const fn = vi.fn()
+
+fn('example')
+
+expect(fn).to.have.been.called // expect(fn).toHaveBeenCalled()
+expect(fn).to.have.been.calledWith('example') // expect(fn).toHaveBeenCalledWith('example')
+expect(fn).to.have.returned // expect(fn).toHaveReturned()
+expect(fn).to.have.callCount(1) // expect(fn).toHaveBeenCalledTimes(1)
+```
+
+## Coverage `ignore start/stop` Ignore Hints
+
+You can now completely ignore specific lines from code coverage using `ignore start/stop` comments.
+In Vitest v3, this was supported by the `v8` provider, but not in v4.0 due to underlying dependency changes.
+
+Due to the community's request, we've now implemented it back ourselves and extended the support to both `v8` and `istanbul` providers.
+
+```ts
+/* istanbul ignore start -- @preserve */
+if (parameter) { // [!code error]
+ console.log('Ignored') // [!code error]
+} // [!code error]
+else { // [!code error]
+ console.log('Ignored') // [!code error]
+} // [!code error]
+/* istanbul ignore stop -- @preserve */
+
+console.log('Included')
+
+/* v8 ignore start -- @preserve */
+if (parameter) { // [!code error]
+ console.log('Ignored') // [!code error]
+} // [!code error]
+else { // [!code error]
+ console.log('Ignored') // [!code error]
+} // [!code error]
+/* v8 ignore stop -- @preserve */
+
+console.log('Included')
+```
+
+See [Coverage | Ignoring Code](/guide/coverage.html#ignoring-code) for more examples.
+
+## Coverage For Changed Files Only
+
+If you want to get code coverage only for the modified files, you can use [`coverage.changed`](/config/coverage.html#coverage-changed) to limit the file inclusion.
+
+Compared to the regular [`--changed`](/guide/cli.html#changed) flag, `--coverage.changed` allows you to still run all test files, but limit the coverage reporting only to the changed files.
+This allows you to exclude unchanged files from coverage that `--changed` would otherwise include.
+
+## Coverage in HTML Reporter and Subpath Deployments
+
+Coverage HTML viewing now works reliably across UI mode, HTML reporter, and browser mode — including when deployed under a subpath. For custom coverage reporters, the new [`coverage.htmlDir`](/config/coverage#coverage-htmldir) option can be used to integrate their HTML output.
