Nodejs 中的单元测试

Question

I have this simple hello world app, I want to write a test for it. I am new to Nodejs so want help in getting started

const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => {
  res.send('Hello World!')
})

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`)
})

Answer 1

您可以使用 jest 和 supertest 编写测试。

Answer 2

in terminal;

npm i supertest
npm i chai

then sample api test is below ;

describe('Hello World Api Test', () => {
    it('should return 200', (done) => {
        request(app)
            .get('/')
            .expect(200)
            .end(function (err, res) {
                if (err) throw err;
                console.log(res);
                expect(res.text).to.equal('Hello world!');
                done()
            });
    });
});
