Methods

construct signature

      
      new (...args: any[]): TestBed

Parameters

args any[]

Returns

TestBed

initTestEnvironment()

      
      initTestEnvironment(ngModule: Type<any> | Type<any>[], platform: PlatformRef, aotSummaries?: () => any[]): TestBed

Parameters

`ngModule`	`Type \| Type[]`
`platform`	`PlatformRef`
`aotSummaries`	`() => any[]`	Optional. Default is `undefined`.

Returns

TestBed

resetTestEnvironment()
Reset the providers for the test injector.
resetTestEnvironment(): void `resetTestEnvironment(): void` Parameters There are no parameters. Returns `void`

resetTestingModule()
resetTestingModule(): TestBedStatic `resetTestingModule(): TestBedStatic` Parameters There are no parameters. Returns `TestBedStatic`

configureCompiler()

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

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

Parameters

config object

Returns

TestBedStatic

configureTestingModule()

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

      
      configureTestingModule(moduleDef: TestModuleMetadata): TestBedStatic

Parameters

moduleDef TestModuleMetadata

Returns

TestBedStatic

compileComponents()
Compile components with a `templateUrl` for the test's NgModule. It is necessary to call this function as fetching urls is asynchronous.
compileComponents(): Promise<any> `compileComponents(): Promise<any>` Parameters There are no parameters. Returns `Promise<any>`

overrideModule()

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

Parameters

`ngModule`	`Type`
`override`	`MetadataOverride`

Returns

TestBedStatic

overrideComponent()

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

Parameters

`component`	`Type`
`override`	`MetadataOverride`

Returns

TestBedStatic

overrideDirective()

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

Parameters

`directive`	`Type`
`override`	`MetadataOverride`

Returns

TestBedStatic

overridePipe()

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

Parameters

`pipe`	`Type`
`override`	`MetadataOverride`

Returns

TestBedStatic

overrideTemplate()

      
      overrideTemplate(component: Type<any>, template: string): TestBedStatic

Parameters

`component`	`Type`
`template`	`string`

Returns

TestBedStatic

overrideTemplateUsingTestingModule()

Overrides the template of the given component, compiling the template in the context of the TestingModule.

      
      overrideTemplateUsingTestingModule(component: Type<any>, template: string): TestBedStatic

Parameters

`component`	`Type`
`template`	`string`

Returns

TestBedStatic

Note: This works for JIT and AOTed components as well.

Parameters

`token`	`any`
`provider`	`object`

Returns

TestBedStatic

Note: This works for JIT and AOTed components as well.

`notFoundValue`	`any`	Optional. Default is `undefined`.

Returns

any

createComponent()

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

Parameters

component Type

Returns

ComponentFixture<T>
