Estimation of code coverage

• estimate code coverage of unit tests
• report this estimate

Most IDEs will report how much of the code is covered. Most notably, non-enterprise editions of Visual Studio use a plug-in OpenCover to do so.

OpenCover is Microsoft and seems a "code coverage tool [only] for .NET 2 and above (Windows OSs only - no MONO)".

I would favor a solution that would integrate well with a CI. What do you think about using coveralls? I set it up for our rSOILWAT2 repository badge - via travis CI. They appear to integrate with c/c++ github repositories and travis.

I am just realizing that the OpenCover repository is using coveralls for themselves as well!

[Zachary-Kramer]

Coveralls looks like a nice tool and appears to integrate well with GitHub. I don't see any better option.

I noticed that for rSOILWAT2, code coverage takes into account the src folder. Do we want this? As a side note, when you click a file within src, coveralls cannot find the file.

I opened an issue for that in rSOILWAT2.

However, it is to be expected that https://coveralls.io cannot find the source files from SOILWAT2 within the src/ folder in the rSOILWAT2 repository. This is because SOILWAT2 is only a submodule in rSOILWAT2. No?

[Zachary-Kramer]

Yes I assume it's because of the submodule, though GitHub can access submodule files just fine, so it's probably just coveralls not being able to access the SOILWAT2 repo (or a lack of submodule support).
