@returnsvoid

autoDetectChanges

2 overloads

Set whether the fixture should autodetect changes.

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

@deprecated

For autoDetect: true, use autoDetectChanges(). We have not seen a use-case for autoDetect: false but changeDetectorRef.detach() is a close equivalent.

@paramautoDetectboolean

Whether to autodetect changes. By default, true.

@returnsvoid

Enables automatically synchronizing the view, as it would in an application.

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

@returnsvoid

isStable

boolean

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

@returnsboolean

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.

@returnsPromise<any>

whenRenderingDone

Promise<any>

Get a promise that resolves when the ui state is stable following animations.

@returnsPromise<any>

destroy

void
