1.  trait ScoverageModule extends Module with ScalaModule

   Adds targets to a mill.scalalib.ScalaModule to create test coverage reports.

   Adds targets to a mill.scalalib.ScalaModule to create test coverage reports.

   This module allows you to generate code coverage reports for Scala projects with Scoverage via the scoverage compiler plugin.

   To declare a module for which you want to generate coverage reports you can Extends the mill.contrib.scoverage.ScoverageModule trait when defining your Module. Additionally, you must define a submodule that extends the ScoverageTests trait that belongs to your instance of ScoverageModule.

   // You have to replace VERSION
   import $ivy.`com.lihaoyi::mill-contrib-buildinfo:VERSION`
   import mill.contrib.scoverage.ScoverageModule
   
   Object foo extends ScoverageModule  {
     def scalaVersion = "2.12.9"
     def scoverageVersion = "1.4.0"
   
     object test extends ScoverageTests {
       def ivyDeps = Agg(ivy"org.scalatest::scalatest:3.0.5")
       def testFrameworks = Seq("org.scalatest.tools.Framework")
     }
   }

   In addition to the normal tasks available to your Scala module, Scoverage Modules introduce a few new tasks and changes the behavior of an existing one.

   - mill foo.scoverage.compile # compiles your module with test instrumentation # (you don't have to run this manually, running the test task will force its invocation)

   - mill foo.test # tests your project and collects metrics on code coverage - mill foo.scoverage.htmlReport # uses the metrics collected by a previous test run to generate a coverage report in html format - mill foo.scoverage.xmlReport # uses the metrics collected by a previous test run to generate a coverage report in xml format

   The measurement data by default is available at out/foo/scoverage/dataDir/dest/, the html report is saved in out/foo/scoverage/htmlReport/dest/, and the xml report is saved in out/foo/scoverage/xmlReport/dest/.

2.  trait ScoverageReport extends define.Module

   Allows the aggregation of coverage reports across multi-module projects.

   Allows the aggregation of coverage reports across multi-module projects.

   Once tests have been run across all modules, this collects reports from all modules that extend mill.contrib.scoverage.ScoverageModule. Simply define a module that extends mill.contrib.scoverage.ScoverageReport and call one of the available "report all" functions.

   For example, define the following scoverage module and use the relevant reporting option to generate a report:

   object scoverage extends ScoverageReport {
     override def scalaVersion     = "<scala-version>"
     override def scoverageVersion = "<scoverage-version>"
   }

   - mill .test # run tests for all modules - mill scoverage.htmlReportAll # generates report in html format for all modules - mill scoverage.xmlReportAll # generates report in xml format for all modules - mill scoverage.consoleReportAll # reports to the console for all modules

   The aggregated report will be available at either out/scoverage/htmlReportAll/dest/ for html reports or out/scoverage/xmlReportAll/dest/ for xml reports.
