Allure - Aggregate Unit Test Reports

Question

I've got a multi-module android project, with unit tests distributed out amongst the various library modules. I've added the io.qameta.allure-adapter plugin to my app module, and all my library modules, and my top-level module has the io.qameta.allure-aggregate-report plugin applied. When I run :allureAggregateReport however I get a bunch of errors about missing configurations:

> Could not resolve all task dependencies for configuration ':allureGenerateCategories'.
   > Could not resolve project :core.
     Required by:
         project :
      > No matching configuration of project :core was found. The consumer was configured to find attribute 'io.qameta.allure' with value 'COPY_CATEGORIES' but:
          - None of the consumable configurations have attributes.
   > Could not resolve project :feature.
     Required by:
         project :
      > No matching configuration of project :feature was found. The consumer was configured to find attribute 'io.qameta.allure' with value 'COPY_CATEGORIES' but:
          - None of the consumable configurations have attributes.
   > Could not resolve project :onscene.
     Required by:
         project :
      > The consumer was configured to find attribute 'io.qameta.allure' with value 'COPY_CATEGORIES'. However we cannot choose between the following variants of project :onscene:
          - devDebugRuntimeElements
          - devReleaseRuntimeElements
          - flankDebugRuntimeElements
          - prodDebugRuntimeElements
          - prodReleaseRuntimeElements
          - qaDebugRuntimeElements
          - qaReleaseRuntimeElements
        All of them match the consumer attributes:
....

Is there any way to get this working?

Answer 1

So, aggregation appears to not be the way to go here.

With allure already working in my test module, I added allure to my library projects. When I run the tests, it generates build/allure-results for each of my modules.

I then finalize the testDebugUnitTest task in my library projects with a task that renames the build/allure-results to add the module as a prefix.

project.tasks.register("copyAllureResults", Copy::class) {
    from(project.layout.buildDirectory.dir("allure-results"))
    into(project.layout.buildDirectory.dir(
        "${project.path.substring(1).replace(":","_")}-allure-results"
    ))
}

project.afterEvaluate {
    tasks.getByName("testDebugUnitTest") {
        finalizedBy("copyAllureResults")
    }
}

Then in my test project, in my dependencies {}, I do:

    Files.walk(
        Paths.get(project.rootProject.projectDir.absolutePath)
    ).filter {
        it.isDirectory() && it.name.endsWith("-allure-results")
    }.forEach {
        logger.debug("Adding Allure Suite: ${it.name}")
        allureRawResultElements(files("${it.absolutePathString()}"))
    }

This adds the results for each module as a separate suite when I run :test:allureReport. The only downside is that testDebugUnitTest has to be run as a separate ./gradlew command, so that the -allure-results folders exist during the configuration when :test:allureReport is run.
