Я создаю приложение реакции с CRA, написал тестовый файл example.test.js. Этот файл содержит:
import axios from 'axios';
axios.get('http://localhost:3000/coins')
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error.response);
});
test('adds 1 + 2 to equal 3', () => {
expect(3).toBe(3);
});
Запустите тест, у меня есть:
PASS src/Api/Coins.test.js
✓ adds 1 + 2 to equal 3 (3ms)

Чтобы убедиться, что API работает, я сделал запрос с curl:
~/Desktop/react-reason/cockpit$ curl http://localhost:3000/coins
[
{
"coinSymbol": "BTC",
"amount": 8.8
},
{
"coinSymbol": "ETH",
"amount": 12.4
},
{
"coinSymbol": "XRP",
"amount": 3412.48
},
{
"coinSymbol": "ETH",
"amount": 0.004
}
Почему он не приносит никаких данных при запуске теста?
