Fixture for debugging and testing a component.

Configures and initializes environment for unit testing and provides methods for creating components and services in unit tests.

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

Deprecated: use waitForAsync(), (expected removal in v12)

Discard all remaining periodic tasks.

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.

Flushes any pending microtasks and simulates the asynchronous passage of time for the timers in the fakeAsync zone by draining the macrotask queue until it is empty.

Flush any pending microtasks.

Returns a singleton of the TestBed class.

Allows injecting dependencies in beforeEach() and it(). Note: this function (imported from the @angular/core/testing package) can only be used to inject dependencies in tests. To inject dependencies in your application code, use the inject function from the @angular/core package instead.

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

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

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.

Configures the test module teardown behavior in TestBed.

Static methods implemented by the TestBed.

Type used for modifications to metadata
