I'm testing using sinon with axios.
// index.js
{
.. more code
const result = await axios.get("http://save")
const sum = result.data.sum
}
And I made a test code by sinon and supertest for e2e test.
// index.test.js
describe('ADMINS GET API, METHOD: GET', () => {
it('/admins', async () => {
sandbox
.stub(axios, 'get')
.withArgs('http://save')
.resolves({sum: 12});
await supertest(app)
.get('/admins')
.expect(200)
.then(async response => {
expect(response.body.code).toBe(200);
});
});
});
But when I test it, it gives me this result.
// index.js
{
.. more code
const result = await axios.get("http://save")
const sum = result.data.sum
console.log(sum) // undefined
}
I think I resolved response. But it doesnt' give any response.
It just pass axios on supertest.
How can I return correct data in this case?
Thank you for reading it.
The resolved value should be { data: { sum: 12 } }.
E.g.
index.js:
const express = require('express');
const axios = require('axios');
const app = express();
app.get('/admins', async (req, res) => {
const result = await axios.get('http://save');
const sum = result.data.sum;
res.json({ code: 200, sum });
});
module.exports = { app };
index.test.js:
const supertest = require('supertest');
const axios = require('axios');
const sinon = require('sinon');
const { app } = require('./index');
describe('ADMINS GET API, METHOD: GET', () => {
it('/admins', async () => {
const sandbox = sinon.createSandbox();
sandbox
.stub(axios, 'get')
.withArgs('http://save')
.resolves({ data: { sum: 12 } });
await supertest(app)
.get('/admins')
.expect(200)
.then(async (response) => {
sinon.assert.match(response.body.code, 200);
sinon.assert.match(response.body.sum, 12);
});
});
});
test result:
ADMINS GET API, METHOD: GET
