[erlang-questions] covertool for eunit without CT? Is that possible?

[Motiejus Jakštys]

Hi,
I want code coverage data to be visible on Jenkins CI using cobertura
plugin. This part of HOWTO[1] is unclear:
"""
Configure cover to export data. Sample cover.spec for Common Test:
{incl_app, app0, details}.
{export, "all.coverdata"}.
"""

Of course, after ./rebar eunit, no relevant XML files are created
(neither all.coverdata is).

How do I configure covertool without CT?

Thanks,
Motiejus Jakštys

Hi Motiejus

I did this a while ago and unfortunately I have no access for that
CI-server anymore so not sure if my information are (still) valid. I
have installed the covertool rebar plugin as described in
https://github.com/idubrov/covertool. Then you must configure the
plugin in your rebar.config file.
So:
"""
plugins, [rebar_covertool]}. % Enable covertool rebar plugin
{covertool_eunit, "eunit.coverage.xml"}. % Output report file name
{covertool_ct, {"ct.coverdata", "ct.coverage.xml"}}. % Source file
name, output report file name
"""
I guess you are referring to line 3 where you configure the covertool
for common test, however if you are not using common test at all you
can omit that line.
I think that is it.

Cheers
Andre

Hi André,

Yes, I did. I set up a very tiny sample project for this:
https://github.com/Motiejus/covertest

Testing on Erlang R15B and rebar binary is copied from your project.

Thanks for your help,
Motiejus

Figured it out, it's rebar fault. If all tests pass, covertool works
as expected.

However, if any of tests fail while running ./rebar eunit, it halts
the VM on the first opportunity and hence does not call
rebar_covertool:eunit/2. I created a trivial patch for rebar and now
working on a test suite which is less trivial. Will submit a patch to
rebar in next couple of days.

Best,
