如何在没有外部通信的情况下将PHPUnit测试保持在内部？

Question

Is it possible to ensure that no tests communicate with an external source? While I think all of my tests take care of mocking out any external dependencies, I'd like to know if there is any sort of catch all to ensure my test suite does not have any unintended communication with third party APIs et cetera.

Answer 1

Since this is tagged as Laravel, I'm going to assume that you'd prefer an answer based on Laravel.

Assuming that you're not testing communication with an external API (which is worth doing at some point), you're going to want to approach it in the same way that you approach anything else.

Mocking.

Both your models and your API library are communicating with a data source. To test your models you mock them, so that you aren't interacting with the database. You need to do the same for your API, mock the class that returns the result, or skip it entirely and throw in an example response.

It all depends entirely on what you are testing. If you don't wish to test how you handle data from the API, simply don't call anything that interacts with the API.
