How can I mock APIs in different frameworks?
You can use libraries like Mockito for Java, Jest for JavaScript, and unittest.mock for Python to mock APIs.
Can you give me an example of mocking an API in Jest?
Sure! In Jest, you can use jest.mock()
to mock a module. For example:
import axios from 'axios';
jest.mock('axios');
test('fetches successfully data from an API', async () => {
axios.get.mockResolvedValue({ data: 'some data' });
const data = await fetchData();
expect(data).toEqual('some data');
});
What about mocking in Python with unittest?
In Python, you can use unittest.mock
like this:
from unittest.mock import patch
@patch('module_name.function_name')
def test_function(mock_function):
mock_function.return_value = 'mocked value'
result = function_call()
assert result == 'mocked value'
Are there any tools for mocking in Ruby?
Yes! In Ruby, you can use RSpec with the allow
method to mock methods. For example:
allow(SomeClass).to receive(:some_method).and_return('mocked value')
