only

Creates a new test scope that’s run exclusively.

static

only(name: string, f: (scope: TestScope) => void): void

Notes

• Multiple exclusive test scopes can be added at the same time. Only the tests in those scopes will run, and none of the others.
• The function argument is still invoked for other describe(...) calls, even if tests won’t be run.

Parameters

• name — The name of the test scope
• f — A function that’s run immediately, which should add tests using the test() function. The new TestScope instance is passed as the only argument.

Example

// only tests in the first scope are run
describe.only("Run these only", () => {
  test("Foo", () => {});
  // ...
})
describe("Not run", () => {
  test("Bar", () => {});
  // ...
})
