In a Go application, how would you handle mocking in a situation where third-party API interactions are involved?
- Create mock implementations of the third-party API's functions.
- Use the actual third-party API for testing.
- Disable network connectivity during testing.
- Rewrite the third-party API's code for testing purposes.
When dealing with third-party API interactions in a Go application, you should create mock implementations of the third-party API's functions. These mock implementations simulate the API's behavior and allow you to control the responses, making your tests independent of the actual API, which may have rate limits, data changes, or downtime. Using the actual third-party API for testing can lead to unpredictable results and is not recommended for unit tests. Disabling network connectivity during testing may be impractical and doesn't provide fine-grained control. Rewriting the third-party API's code for testing purposes is generally not feasible and introduces maintenance challenges.
