typescript - 我如何模拟 angular-auth-oidc 客户端以返回假数据

Question

我如何模拟 Angular-auth-oidc-client 以使用 karma-jasmine 返回一些假 token 。下面是我需要编写单元测试用例的代码。

getToken() {
    return this.oidcSecurityService.getToken();
}

Answer 1

Here is my article which covers all such basic testing scenarios首先。 There is another article which specifically talks about this case 。请随时提供您的反馈

您需要创建一个 stub 来模拟oidcSecurityService的行为，

export class OidcSecurityServiceStub{
   getToken(){
      return 'some_token_eVbnasdQ324';
   }
   // similarly mock other methods "oidcSecurityService" as per the component requirement

}

然后在spec文件中，使用useClass，如下在TestBed中:

TestBed.configureTestingModule({
     declarations: [ WhateverComponent],
     providers:    [ {provide: OidcSecurityService(or whatever the name is), useClass: OidcSecurityServiceStub} ]
  });
