异步等待Node.js单元测试代码使用Chai和mocha

Question

我对节点和表达式还很陌生。并且一直在尝试使用mocha、chai编写测试代码。这是源代码的一部分。

googleService.js:

const axios = require('./axios');
exports.hitGoogle = async (requestUrl, payload) => {
let response = {};
await axios.post(`${requestUrl}`, payload)
.then((resp) => {
response = resp;
console.log(response);
})
.catch((err) => {
console.error(err);
});
return response;
};

readGoogle.js

const googleService = require('./googleService');
exports.execute = async (data) => {
console.log(`data ${JSON.stringify(data)}`);
console.log(`Name ${data.name}`);
console.log(`Salary ${data.salary}`);
console.log(`Age ${data.age}`);
const payload = { name: data.name, salary: data.salary, age: data.age };
await googleService.hitGoogle('http://dummy.restapiexample.com/api/v1/create', payload)
.then((response) => {
if (response.status === 200 || response.status === 201) {
console.log(response.status);
return true;
}
return false;
})
.catch((err) => {
console.log(err);
});
return true;
};

这是我的单元测试文件：

const readGoogle = require('./readGoogle');
const jmsPayload = { age: '23', name: 'test', salary: '123' };
describe('Google ', () => {
it('POST: Google.', async () => {
readGoogle.execute(jmsPayload).then((result) => {
results = result;
console.log(`Final Result : ${results.toString()}`);
});
});

当我执行这个测试文件时，post是成功的，

hitGoogle url=http://dummy.restapiexample.com/api/v1/create
hitGoogle payload=[object Object]
{ status: 200,
statusText: 'OK',

从测试类传递到readGoogle.js的输入值也在其中读取，

data {"age":"23","name":"test","salary":"123"}
Name test
Salary 123
Age 23
**But I am getting Promise as output.** 
**SO I have rendered the promised value to a normal string and getting 'true' as final output.**

此外，

• 1(这是测试异步等待模块的正确方法吗？

  2( 我们需要在这个测试代码中添加其他东西吗，比如Settimeout还是beforeEach或afterEach块？

  3( 我们需要使用Sinon进行间谍活动还是在"有效载荷"中添加存根在谷歌服务.js中？

有人能帮我或建议我走正确的路吗？

尝试异步方式逐个执行测试用例，顺序如下，

const readGoogle = require('./readGoogle');
const jmsPayload = { age: '23', name: 'test', salary: '123' };
const common = require('./common');
const chaiHttp = common.chaiHttp;
common.chai.use(chaiHttp);
describe('Google ', () => {
common.mocha.before((done) => {
// Wait for the server to start up
setTimeout(() => {
done();
}, 1000);
});
it('POST: Google.', async () => {
const result = readGoogle.execute(jmsPayload);
console.log(`Final Result : ${result.toString()}`);
});
it('POST: Google.', async () => {
const result = readGoogle.execute(jmsPayload);
console.log(`Final Result : ${result.toString()}`);
setTimeout(() => {
}, 1000);
});
it('POST: Google.', async () => {
const result = readGoogle.execute(jmsPayload);
console.log(`Final Result : ${result.toString()}`);
});
it('POST: Google.', async () => {
const result = readGoogle.execute(jmsPayload);
console.log(`Final Result : ${result.toString()}`);
});
it('POST: Google.', async () => {
const result = readGoogle.execute(jmsPayload);
console.log(`Final Result : ${result.toString()}`);
});
it('POST: Google.', async () => {
const result = readGoogle.execute(jmsPayload);
console.log(`Final Result : ${result.toString()}`);
});
it('POST: Google.', async () => {
const result = readGoogle.execute(jmsPayload);
console.log(`Final Result : ${result.toString()}`);
});
});

但我得到了，

错误：超时时间超过2000ms。对于异步测试和钩子，请确保调用"done(("；如果返回Promise，请确保其解决

提前感谢

Answer 1

您可以使用以下两种解决方案：

1(回调约定：

describe('Google ', () => {
it('POST: Google.', (done) => {
readGoogle.execute(jmsPayload).then((result) => {
results = result;
console.log(`Final Result : ${results.toString()}`);
done();
}).catch((e) => {
done();
});
});
});

2(异步/等待约定

describe('Google ', () => {
it('POST: Google.', async () => {
const results = await readGoogle.execute(jmsPayload);
console.log(`Final Result : ${results.toString()}`);
});
});
