I'm not sure why the GET request can't send me back the data
Basically, my GET request looks like:
router.get('/', (req, res) => {
res.set('Content-Type', 'text/html')
res.status(200).send(Buffer.from('<p>some html</p>'))
});
Then I use supertest to test this route.
test('test', async () => {
const res = await request(app)
.get('/')
expect(res.statusCode).toBe(200);
expect(res.body.toString()).toBe("<p>some html</p>");
});
Then I console.log(res.body), it returns me the empty{}
I'm not sure why the route return give me the empty obj.
The response data should be get from res.text not res.body.
app.js:
const app = require('express')();
app.get('/', (req, res) => {
res.set('Content-Type', 'text/html');
res.status(200).send(Buffer.from('<p>some html</p>'));
});
module.exports = app;
app.test.js:
const app = require('./app');
const request = require('supertest');
describe('71328567', () => {
test('should pass', async () => {
const res = await request(app).get('/');
expect(res.type).toBe('text/html');
expect(res.text).toBe('<p>some html</p>');
});
});
Test result:
PASS stackoverflow/71328567/app.test.js
