How do I test Vue.js components that use Axios?
You can use libraries like Jest and Vue Test Utils to test Vue components. Mocking Axios is essential for isolating tests.
Can you show me an example of mocking Axios in a test?
Sure! You can use jest.mock('axios')
to mock Axios. Then, in your test, you can define the response you want to return.
What if I want to test error handling in my component?
You can simulate an error response by using axios.mockImplementationOnce
to throw an error, and then assert how your component handles it.
Are there any best practices for testing with mocks?
Yes! Keep your tests isolated, avoid testing implementation details, and ensure your mocks reflect real API behavior.
