How to: :clap: Ensuring that on network failures, the circuit breaker can save the day
```javascript
  test('When users service replies with 503 once and retry mechanism is applied, then an order is added successfully', async () => {
  //Arrange
  nock.removeInterceptor(userServiceNock.interceptors[0])
  nock('http://localhost/user/')
    .get('/1')
    .reply(503, undefined, { 'Retry-After': 100 });
  nock('http://localhost/user/')
    .get('/1')
    .reply(200);
  const orderToAdd = {
    userId: 1,
    productId: 2,
    mode: 'approved',
  };

  //Act
  const response = await axiosAPIClient.post('/order', orderToAdd);

  //Assert
  expect(response.status).toBe(200);
});
```
