Coverage per Test - Gradle Plugin

Collect coverage reports per test case execution instead of the entire test suite.

This is a gradle plugin that works with JUnit 5 and Jacoco.

Getting Started

• Add this plugin (and Jacoco) to the plugins section of your Gradle.

  Kotlin:

  plugins {
      jacoco
      id("io.testaxis.coveragepertest") version "1.0.0"
  }

  Groovy:

  plugins {
      id 'jacoco'
      id "io.testaxis.coveragepertest" version "1.0.0"
  }

• Set the tool version of Jacoco to the version below or higher.

  Kotlin/Groovy:

  jacoco {
      toolVersion = "0.8.6"
  }

• Set JUnit's extension autodetection property to true to enable the runtime.

  Kotlin:

  tasks.withType<Test> {
      systemProperty("junit.jupiter.extensions.autodetection.enabled", "true")
      useJUnitPlatform()
  }

  Note that the runtime interferes with regular coverage reports. Enable the runtime dynamically if you want to generate a regular coverage report for your entire test suite.

• Optionally, configure any of the options of the plugin below. You can leave the configuration block out if you do not want to set any custom options.

  Kotlin:

  coveragePerTestConfig {
      inputDirectory.set(file("/custom-reports-input-directory"))
      outputDirectory.set(file("/custom-reports-output-directory"))
  }

Tasks

Run tests and generate coverage reports per test:

$ gradlew test coveragePerTest

By default, the reports will be located in build/coveragepertest/xml.

Development

The plugin consists of two parts: the actual Gradle plugin (plugin-build/) and the runtime library (runtime/).

Run the tests and static analysis tools:

$ gradlew preMerge
