Classes

ComponentFixture

Fixture for debugging and testing a component.

InjectSetupWrapper
TestComponentRenderer

An abstract class for inserting the root test component element in a platform independent way.

Functions

async

Wraps a test function in an asynchronous test zone. The test will automatically complete when all asynchronous calls within this zone are done. Can be used to wrap an inject call.

discardPeriodicTasks

Discard all remaining periodic tasks.

fakeAsync

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.
flush

Simulates the asynchronous passage of time for the timers in the fakeAsync zone by draining the macrotask queue until it is empty. The returned value is the milliseconds of time that would have been elapsed.

flushMicrotasks

Flush any pending microtasks.

inject

Allows injecting dependencies in beforeEach() and it().

resetFakeAsyncZone

Clears out the shared fake async zone for a test. To be called in a global beforeEach.

tick

Simulates the asynchronous passage of time for the timers in the fakeAsync zone.

withModule

Structures
