fakeAsync

function

Wraps a function to be executed in the fakeAsync zone:

  • Microtasks are manually executed by calling flushMicrotasks().
  • Timers are synchronous; tick() simulates the asynchronous passage of time.
  
    function fakeAsync(  fn: Function,  options?: { flush?: boolean | undefined; } | undefined): (...args: any[]) => any;

(...args: any[]) => any

Wraps a function to be executed in the fakeAsync zone:

  • Microtasks are manually executed by calling flushMicrotasks().
  • Timers are synchronous; tick() simulates the asynchronous passage of time.

Can be used to wrap inject() calls.

@paramfnFunction

The function that you want to wrap in the fakeAsync zone.

@paramoptions{ flush?: boolean | undefined; } | undefined
  • flush: When true, will drain the macrotask queue after the test function completes. When false, will throw an exception at the end of the function if there are pending timers.
