Question

您想在我的角度组件中测试真实服务。但我得到低于错误。 没有服务blservice的提供商

    def __OnClickSaveLoginButton(self):
    id = self.idEditLine.GetText()
    pwd = self.pwdEditLine.GetText()
    if (len(id) == 0 or len(pwd) == 0):
        self.PopupNotifyMessage("ID and Password required",self.SetIDEditLineFocus)
        return
    file_object  = open("account.cfg", "w")
    file_object.write(id+"\n"+pwd)
    self.PopupNotifyMessage("Saved.",self.SetIDEditLineFocus)
    file_object.close()

错误：

以这种方式解决：

import {async} from '@angular/core/testing';


beforeEach(async(() => {
  TestBed.configureTestingModule({
    providers: [BlService]
  });
}));

Karma：Angular 4没有服务提供商
