Incorrect Cobertura file sources generated

Consider the following snippet.

Observe <source>/Users/arcivanov/Documents/src/cschcs/cschcs-manager

Observe filename="another_api/models.py" line-rate="1" name="models.py"

The problem is, this is pyb and the sources are actually located in src/main/python.

Unfortunately, coverage simply uses current directory for sources for unknown reason (https://github.com/nedbat/coveragepy/blob/master/coverage/xmlreport.py#L146) -files.relative_directory() is always current dir and disregards Coverage(source=['src/main/python'])

The expected result would, naturally, be <source>/Users/arcivanov/Documents/src/cschcs/cschcs-manager/src/main/python

I will submit a PR on GH

[nedbat]

Can you provide me with a reproducible scenario?

1. Create a Python Builder project (pybuilder > v0.11.0)
2. Have some source files and unit tests
3. Run a build.
4. Inspect target/reports/unittest_coverage.xml

Let me see if there are any public projects available you can look at (all mine are private).

Another place where "relative path" is used relative to current directory and not the config.source relative to which the file was found https://github.com/nedbat/coveragepy/blob/master/coverage/python.py#L114

[nedbat]

@arcivanov Hmm, I'm afraid I need a considerably greater level of detail in the instructions in order to duplicate your issue.

I have submitted the fix here #5
Please let me know if the nature of the fix is unclear

[nedbat]

If you could use Python Builder to make a small project, and attach a zip file here, it'll be easier for me to assess the problem and the solution. Or perhaps if the pull request had some tests?

Sample project

Original comment by Arcadiy Ivanov (Bitbucket: arcivanov, GitHub: arcivanov)

#!bash

pip install --pre pybuilder
tar -xf issue_439.tar.gz
cd issue_439
pyb
less target/reports/coverage.xml

Observe <source>issue_439 and not issue_430/src/python</source>

@nedbat did the provided example work for you?

[nedbat]

Yes, thanks, this reproduces the behavior. I need to understand what's happening at the API level now.

@nedbat see the PR I sent: the code change is tiny and demonstrates the problem - the sources are assumed to be in "." always for whatever reason

[nedbat]

@arcivanov just to be clear: your PR doesn't demonstrate the problem, it contains a fix. I want to see and understand the problem for myself. This is on my list, I will get to it soon.

Got it. Thanks!
