Class Description

Fixture for debugging and testing a component.

Constructor

constructor(componentRef: ComponentRef<T>, ngZone: NgZone, _autoDetect: boolean)

Class Details

debugElement : DebugElement

The DebugElement associated with the root element of this component.

componentInstance : T

The instance of the root component class.

nativeElement : any

The native element at the root of the component.

elementRef : ElementRef

The ElementRef for the element at the root of the component.

changeDetectorRef : ChangeDetectorRef

The ChangeDetectorRef for the component

componentRef : ComponentRef<T>

ngZone : NgZone

detectChanges(checkNoChanges?: boolean) : void

Trigger a change detection cycle for the component.

checkNoChanges() : void

Do a change detection run to make sure there were no changes.

autoDetectChanges(autoDetect?: boolean)

Set whether the fixture should autodetect changes.

Also runs detectChanges once so that any existing change is detected.

isStable() : boolean

Return whether the fixture is currently stable or has async tasks that have not been completed yet.

whenStable() : Promise<any>

Get a promise that resolves when the fixture is stable.

This can be used to resume testing after events have triggered asynchronous activity or asynchronous change detection.

destroy() : void

Trigger component destruction.
