Variable TestClock

Type Declaration

• advance: (ms: number) => IO<TestClock, never, void>

  Creates an IO that advances the TestClock.

• context: () => { clock: TestClock; context: Context<TestClock> }

  Creates a context with a TestClock for testing.

• make: () => TestClock

  Creates a new TestClock instance

• setTime: (ms: number) => IO<TestClock, never, void>

  Creates an IO that sets the TestClock time.

• tag: Tag<TestClock>

  Tag for dependency injection

• test: <A>(f: (clock: TestClock) => Promise<A>) => Promise<A>

  Creates a test environment with a TestClock and runs the test function.

  Example

  await TestClock.test(async (clock) => {
    const result = await IO.sleep(100).map(() => "done")
      .pipe(clock.runWithClock)
    expect(result).toBe("done")
  })
  Copy

• get get(): IO<TestClock, never, TestClock>

  Creates an IO that accesses the TestClock from the environment.

• get runAll(): IO<TestClock, never, void>

  Creates an IO that runs all pending tasks.
