#48407 Add test coverage module for lib389 repo
Closed: wontfix None Opened 8 years ago by spichugi.

We need some module that will show us how much lines of code is covered by tests. Also, we need to show this information somewhere.

Let's discuss it and implement after that.


There are two factors to consider in this.

We can cover lines in the python code very easily with something like coverage [0]

I think what's more important is to find a way to determine code coverage in the main body of ns-slapd C code. But this ticket I believe is more about lib389.

[0] https://pypi.python.org/pypi/pytest-cov

I've tested '''pytest-cov''' and it works perfectly.

All we need is to:
install '''python-pytest-cov''' package from Fedora or EPEL repos (for CI we should add "pytest-cov" line to requirements.txt);
create '''.coveragerc''' file at the root of the repo
{{{
[run]
omit = lib389/tests/
}}}
add "--cov-config .coveragerc --cov=lib389" to our py.test command

And then we will have coverage report printed in the end of the test run.

The issue that we should resolve is RHEL compatibility, because there is no package in default RHEL repos.

What do you think, team? Should we set up all these steps anyway, even there is no RHEL package with pytest-cov?

I have no issue with that because we would likely run this on our local machines or controlled dev systems.

This is just checking coverage of what we test internal to lib389. We can't easily add test coverage to the C code base.

Take a look at #48399 because we may be able to add the test-with-coverage or similar as a make target to help us in the team out too.

Can you add the .coveragerc as a patch?

Can you provide an example of the current output?

Thanks for your work on this!

This is how test coverage output looks like.

I had a look on #48399. Viktor works on that now and he plans to provide some script that related to this issue soon.

P.S. I will continue to search some ways to cover our 389-ds the C code base.

I'm happy with this, ack.

So can we close this ticket?
