说明
TestBed is the primary api for writing unit tests for Angular applications and libraries.
Note: Use TestBed in tests. It will be set to either TestBedViewEngine or TestBedRender3 according to the compiler used.
方法
|
|---|
Initialize the environment for testing with a compiler factory, a PlatformRef, and an angular module. These are common to every test in the suite. |
initTestEnvironment(ngModule: Type<any> | Type<any>[], platform: PlatformRef, aotSummaries?: () => any[]): void
initTestEnvironment(ngModule: Type<any> | Type<any>[], platform: PlatformRef, aotSummaries?: () => any[]): void
参数返回值void
|
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/<platform_name>/testing'. |
|
|---|
Reset the providers for the test injector. |
