Tests and project in two modules

[Kwestor]

We have following infrastructure in our company:

• parentProject
  • projectA
  • projectA-tests
  • projectB
  • projectB-tests
  • ...

We would like to check coverage of projectA with projectA-tests etc.

Do you have any plans to support such setup? Or how could I hack such solution (or maybe implement it in scoverage)?

[maiflai]

I think we managed to cover this in a separate thread - scoverage/gradle-scoverage#33 (comment)

If you're using Gradle, please could you test the following?

configure(subprojects.findAll { it.name.endsWith('-tests') }) {
  def mainProject = project(":${project.name.minus('-tests')}")
  dependencies {
    testCompile mainProject
  }
  scoverage {
    sources = mainProject.extensions.scoverage.sources
    dataDir = mainProject.extensions.scoverage.dataDir
    reportDir = mainProject.extensions.scoverage.reportDir
  }
  testScoverage {
    classpath = mainProject.sourceSets.scoverage.runtimeClasspath + sourceSets.test.runtimeClasspath
  } 
}

You might also need to configure the 'main' projects to skip the testScoverage and reportScoverage tasks.

subprojects {
    testScoverage { onlyIf { project.name.endsWith('-tests') }  }
    reportScoverage { onlyIf { project.name.endsWith('-tests') } }
}

I'll test this next Friday, as I'm busy with something else till then. Thanks!

Hi,

I tested sample from https://github.com/scoverage/gradle-scoverage-sample and have some problems with generating report:

It looks like wrong path is generated.

testScoverage works ok.

Thanks - this appears to be a duplicate of #80. I'm not sure I agree with the diagnosis there, but I'll take a look upstream.

[Kwestor]

Maybe, but here I did not run aggregate task, only report. I'll look into that.

[Kwestor]

Problem lies in ScoverageHtmlWriter.writeFile. It calculates relative paths like this:

private def relativeSource(src: String): String =
  src.replace(sourceDirectory.getCanonicalPath + File.separator, "")

And in this case (tests in separate module) values looks like this:

src = "C:\Users\Jerzy\Workspaces\GitHub\scoverage\gradle-scoverage-sample\separate-tests\a\src\main\scala\Hello.scala"
sourceDirectory.getCanonicalPath = "C:\Users\Jerzy\Workspaces\GitHub\scoverage\gradle-scoverage-sample\separate-tests\a-tests\src\main\scala"

Second one is not a prefix of first, and this generates incorrect paths.

@sksamuel do you have some idea about how to handle this problem?

[sksamuel]

We need to handle both the location of the source and the package name
seperately when generating the statement coverage I assume.

@sksamuel @maiflai I now have version that work if you have all main sources in one project, and all test sources in another (this commit).

Unfortunately, as soon as you add something to main source set in test project, html report generation fails relativeSource method assumes both sourceDirectory.getAbsolutePath is a prefix of measured file path.

On windows this fails immediately, as you cannot have to c:\ in your path, on unix it just generates wrong paths to html files and report is broken (see this commit for repro).

I can fix this (we really like to include scoverage in our project) and contribute a fix, but some guidance on how you want to tackle this problem will be helpful.
