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` Parameters There are no parameters. Returns `void`

resetTestingModule()
`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>` 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.

overrideProvider()

Overwrites all providers for the given token with the given provider definition.

`overrideProvider(token: any, provider: { useValue: any; }): TestBedStatic`

Parameters

`token`	`any`
`provider`	`{ useValue: any; }`

Returns

TestBedStatic

`overrideProvider(token: any, provider: { useFactory?: Function; useValue?: any; deps?: any[]; }): TestBedStatic`

Parameters

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

Returns

TestBedStatic

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

get()

deprecated from v8.0.0 use Type or InjectionToken This does not use the deprecated jsdoc tag on purpose because it renders all overloads as deprecated in TSLint due to https://github.com/palantir/tslint/issues/4522.

`get(token: any, notFoundValue?: any): any`

Parameters

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

Returns

any

createComponent()

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

Parameters

component Type

Returns

ComponentFixture<T>
