离子2业力-茉莉花单元测试

Question

我在因果报应中做测试用例时有问题--茉莉。配置已经完成，但我发现在构建测试用例时存在困难。离子的提供者被发现的问题。

app.component.spec.ts

import { UsersProvider } from '../providers/users/users';
import { TestBed, inject } from '@angular/core/testing';
import { HttpClientTestingModule, HttpTestingController } from '@angular/common/http/testing';
import { Http } from '../../node_modules/@angular/http';

let zone: any;
describe("TEST 1", () => {
let service: UsersProvider;
    let httpMock: HttpTestingController;
    beforeEach(() => {
        TestBed.configureTestingModule({
            providers: [UsersProvider]
        });
        service = TestBed.get(UsersProvider);
    });

    afterEach(() => {
        httpMock.verify();
    });

    describe('#registerUser tests', () => {
        it("Equality Test", function () {
        expect("Hello").toEqual("Hello");
        });
    });
});

通过将随机设置为假，我们再也看不到这些问题了。我们通过在karma.conf.js:中添加此设置来做到这一点。

config.set({
    client: {
      jasmine: {
        random: false
      }
    }
  });

试试看。
