Methods

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

Parameters
args any[]
Returns

TestBed

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

Reset the providers for the test injector.

resetTestEnvironment(): void

Parameters

There are no parameters.

Returns

void

resetTestingModule(): TestBedStatic

Parameters

There are no parameters.

Returns

TestBedStatic

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

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

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

Parameters
ngModule Type
override MetadataOverride
Returns

TestBedStatic

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

Parameters
component Type
override MetadataOverride
Returns

TestBedStatic

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

Parameters
directive Type
override MetadataOverride
Returns

TestBedStatic

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

Parameters
pipe Type
override MetadataOverride
Returns

TestBedStatic

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

Parameters
component Type
template string
Returns

TestBedStatic

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.

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.

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

deprecatedOverrideProvider(token: any, provider: { useValue: any; }): void

Parameters
token any
provider { useValue: any; }
Returns

void

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

Parameters
token any
provider object
Returns

TestBedStatic

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

Parameters
token any
notFoundValue any

Optional. Default is undefined.

Returns

any

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

Parameters
component Type
Returns

ComponentFixture<T>
