Google test for integration tests?

[Brett Thomas]

Hi all,

Apologize for the really basic question here, I'm just getting started. I need to add tests to an existing code base, and exploring whether Google Test is a good choice. It looks great for unit tests, but what about testing program execution end to end? (Not sure if you prefer to call these integration tests/system tests/etc)

For example, our program has a "startproject" command, which creates and initializes 4 files. Without a testing framework, I'd just write a python script that executes a system call and validates a hash of each of the files. Do you all usually use Google Test for this, or do you maintain a separate integration test suite? If Google Test is the answer, could anybody point me to documentation of best practices for integration tests?

Thanks for the help, and sorry again for the noob question,
Brett

For any "black box" testing (system/acceptance) I'm not sure there's
any advantage to using a C++ based test system. Python would be much
quicker/easier. Once I'm actually testing objects (unit/integration)
then Google Test/Mock are very helpful.

I agree.

Note that Google Test itself uses Python for some of its end-to-end tests.
