Support for multi-project builds

[elbiczel]

It would be great to add support for multi-project builds. Currently I haven't found a way to aggregate all test coverage data from multiple modules into a single report.

Hi @elbiczel

If you are using Sonar to consume your reports it can be done easily :

Hi @D-Roch
Thanks for a fast reply.
I was thinking about using coveralls.io and sbt-coveralls plugin. If it's not supported in the coveralls plugin I would be willing to contribute either to scalac-scoverage-plugin or to sbt-coveralls if you give me some initial guidance where to begin.

If you are looking for a sample project using Scoverage + coveralls you should check :
https://github.com/scoverage/sbt-coveralls
I have never done a multi-project report using coveralls but I just checked at the sourcecode and it looks like it's on hold since we moved from SCCT to Scoverage :
https://github.com/scoverage/sbt-coveralls/blob/master/src/main/scala/CoverallsPlugin.scala#L45

I have some work that isn't checked in that will aggregate the results together. I need to sit down and work out how to add it to SBT as a next step. Let's say we'll have this ready within 2 weeks.

That's awesome news! Thank you @sksamuel

I, too, would appreciate multi-project support. As usual, keeping config/set-up as simple to get going as possible would be a real win. Needing to mess with scoverage or SonarQube is a real disincentive. I have many other problems to solve without setting up those tools!

Thanks for your work in moving scct to be statement-oriented. Much appreciated.

Hi @sksamuel,
do you have any update on this?

[elbiczel]

Hi @sksamuel, @D-Roch, are you planning to implement this feature? I'm really stuck on that, so I could implement it on my own, but I just think it would be a waste of time if we were both doing the same thing.

I also miss this... it would be especially useful when single project is forced to become split due to macros sub-project

[yardena]

Any news on this? We migrated to scoverage from scct and miss the combined HTML reports...

Any documentation on how to get this set up? I've been trying the latest version of scoverage on my multi-module project and can't get the scoverage reports to merge.

Thanks

Trying to figure out if my coverage is something this would fix or a separate edge case.

As part of a multi-project sbt build, I have a bunch of case classes, support types, etc. in a separate library project that under the current scoverage:test command end up with 0% coverage because they are all covered in tests in another project. Would multi-project coverage catch those omissions or is multi-project just about aggregating the multiple report files into a single one?

thanks!
