SSH 的单元测试还是集成测试？

Question

I am currently using phpseclib to allow me to connect to SSH.

I will be using phpseclib quite a lot to connect to many servers via SSH and execute some commands.

I have created a SecureShell class (like a adaptor pattern) with a few methods such as login() and exec() . These method will execute the server via phpseclib object.

I am trying to work out what is a good way to test the login and execute a command a server - should I mock it SecureShell class or do Integration testing which mean I need a separate real testing server (not development local server?)

Answer 1

Ultimately, you would want both.

You would want unit tests with a mocked SecureShell so that you know that your code is asking to run the correct commands. You would also want to have some sort of integration tests that you can verify that your connection is setup correctly and will work in production.

Tests are so that you are confident that there are no problems with your code and that everything will work correctly. So you want whatever tests will provide you with that confidence.
