TestBed

TestBed is the primary api for writing unit tests for Angular applications and libraries.

initTestEnvironment(ngModule: Type<any>, platform: PlatformRef) : TestBed

Initialize the environment for testing with a compiler factory, a PlatformRef, and an angular module. These are common to every test in the suite.

This may only be called once, to set up the common providers for the current test suite on the current platform. If you absolutely need to change the providers, first use resetTestEnvironment.

Test modules and platforms for individual platforms are available from '@angular//testing'.

resetTestEnvironment()

Reset the providers for the test injector.

resetTestingModule() : typeof TestBed

configureCompiler(config: {providers?: any[]; useJit?: boolean;}) : typeof TestBed

Allows overriding default compiler providers and settings which are defined in test_injector.js

configureTestingModule(moduleDef: TestModuleMetadata) : typeof TestBed

Allows overriding default providers, directives, pipes, modules of the test injector, which are defined in test_injector.js

compileComponents() : Promise<any>

Compile components with a templateUrl for the test's NgModule. It is necessary to call this function as fetching urls is asynchronous.

overrideModule(ngModule: Type<any>, override: MetadataOverride<NgModule>) : typeof TestBed

overrideComponent(component: Type<any>, override: MetadataOverride<Component>) : typeof TestBed

overrideDirective(directive: Type<any>, override: MetadataOverride<Directive>) : typeof TestBed

overridePipe(pipe: Type<any>, override: MetadataOverride<Pipe>) : typeof TestBed

get(token: any, notFoundValue?: any)

createComponent(component: Type<T>) : ComponentFixture<T>
