vitest 2.1.0

v2.1.0

on Node.js Yarn

This release makes another big change to the Browser Mode by introducing locators API:

test('renders blog posts', async () => {
  const screen = page.render(<Blog />)

  await expect.element(screen.getByRole('heading', { name: 'Blog' })).toBeInTheDocument()

  const [firstPost] = screen.getByRole('listitem').all()

  await firstPost.getByRole('button', { name: 'Delete' }).click()

  expect(screen.getByRole('listitem').all()).toHaveLength(3)
})

You can use either vitest-browser-vue, vitest-browser-svelte or vitest-browser-react to render components and make assertions using locators. Locators are also available on the page object from @vitest/browser/context.

Potential Breaking Change

• workspace:
  • Correctly resolve workspace globs and file paths  -  by @sheremet-va in #6316 (afdcb)
  • This changes how the custom glob pattern in the workspace config is treated. Any file matching the glob is considered a Vitest config file. Any folder matching the glob pattern is treated as a workspace project and is subject to the regular config resolution (single vitest.config.ts or vite.config.ts inside the folder)
  • For example, projects/* will match anything inside the projects folder. If it's a folder, we try to find the config inside that folder (if there is none, it is still treated as a project with the default config). If it's a file, it will be treated as a Vitest config. projects/**/* previously would assume that you only wanted to have folders as projects, but now it will match every single file insideprojects.
  • This change doesn't affect non-glob usage.
