Question

我试图让茉莉花测试在Karma中运行Aurelia项目，该项目需要自定义配置启动配置。这是测试

it("dreams to be a plugin", async () => {
        const component = StageComponent.withResources();
        component.configure = (aurelia) => {
            return aurelia.use.standardConfiguration();
        };
        await component.create(bootstrap);
        expect(true).toBeTruthy();
    });

不幸的是测试失败了，因为对component.create()的调用没有返回，并且jasmine超时并且测试失败。

Here是一个显示问题的回购。

我错过了什么？

Answer 1

component.create()会返回Promise吗？ async / await如果是Promise，则应该有效。

it("should support async/await tests", async () => {
  let flag = false;
  flag = await asyncSetFlagToTrue();
  expect(flag).toBeTruthy();
});

function asyncSetFlagToTrue() {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve(true);
    }, 1000);
  });
}

<强>更新

我从GitHub克隆并向component-tester.spec.ts添加了两个测试。两人都过去了。

it('should test async call using done', (done) => {
  component.configure = (aurelia) => {
    return aurelia.use.standardConfiguration();
  };
  component.create(bootstrap).then(() => done());
  expect(true).toBeTruthy();
});

it('should test async call using async/await', async () => {
  component.configure = (aurelia) => {
    return aurelia.use.standardConfiguration();
  };
  await component.create(bootstrap);
  expect(true).toBeTruthy();
});

对component.create（）的异步调用不返回
