Tests

Every module should have a separate test module. The test module has the name, prepended with test_. e.g. authentication.py and test_authentication.py. All test modules are located in the test package, where they are located in the real project (server_side, client_side, general).

In tests often a special setup is needed. Because some setups are needed in multiple different modules, the setups may be written as separate helper functions. These helper functions may be located in the test file or in separate modules. A helper function should be located in a higher level, the more general it is and the more often it is used.

Helper functions are prepended with h_ to signal, that this is not executed in the real program, but only in tests.

Network vs normal tests

Some functions call functions over the network. For them a server/client process needs to be running.

Rules

• functions that would make a call over the network are always mocked. The other side implementation is out of scope
• functions that are called over the network can be mocked depending on the config
