testNamePattern

• Type: string | RegExp
• CLI: -t <pattern>, --testNamePattern=<pattern>, --test-name-pattern=<pattern>

Run tests with full names matching the pattern. If you add OnlyRunThis to this property, tests not containing the word OnlyRunThis in the test name will be skipped.

import { expect, test } from 'vitest'

// run
test('OnlyRunThis', () => {
  expect(true).toBe(true)
})

// skipped
test('doNotRun', () => {
  expect(true).toBe(true)
})

The pattern is matched against the test's full name: the enclosing suite names and the test name joined with ' > ' (the same string shown in the reporter output). For example, the test below has the full name math > adds, so it is matched by -t 'math > adds' or -t adds:

import { describe, expect, test } from 'vitest'

describe('math', () => {
  test('adds', () => {
    expect(1 + 1).toBe(2)
  })
})

WARNING

Before Vitest 5, the segments were joined with a single space (math adds) to mirror Jest. See the migration guide for details.
