Question

我有以下异步函数返回Promise。

static getAccessToken(env: DeploymentEnv, username: string, password: string): Promise<AccessToken>;

现在，这是我为它写的单元测试。

it("should be able to get access token",async ()=>{
    let accessToken = await IModelHubServiceBusClient.getAccessToken('QA',
                      'abc@xyz.com',
                      'abc')!;

    assert.exists(accessToken);
});

运行时，它未通过测试说出以下错误：

should be able to get access token:
 Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

我做错了什么，任何建议都将受到赞赏。提前致谢。

如果您测试异步代码

，则需要使用done回调

it("should be able to get access token",async (done)=>{
    let accessToken = await IModelHubServiceBusClient.getAccessToken('QA',
                      'bistroDEV_pmadm1@mailinator.com',
                      'pmadm1')!;

    assert.exists(accessToken);
    done();
});
