我的拦截器是：
@Injectable()
export class ErrorInterceptor implements HttpInterceptor {
constructor(private _ngbModal: NgbModal) {}
intercept(request: HttpRequest<any>,next: HttpHandler): Observable<HttpEvent<any>> {
return next.handle(request)
.catch((err) => {
let componentInstance = this._ngbModal.open(ErrormodalComponent,{size: 'sm',backdrop: 'static' }).componentInstance
switch(err.status) {
case 401:
componentInstance["message"] = "User session lost,please logout and log back in."
break;
case 404:
componentInstance["message"] = "API Route Not found"
break;
default:
componentInstance["message"] = "API Currently Unavailable. Please try again."
break;
}
return Observable.throw(err);
})
}
}
我想编写一个测试,检查模式是否已根据状态使用适当的消息打开.
谢谢
解决方法
我会嘲笑_ngbModal并使用open方法并返回一个组件实例并检查componentInstance上的消息键.
由于_ngbModal是第三方并已经过测试,因此需要实际测试模态.
希望这可以帮助.
