JaCoCo不适用于Robolectric测试

Question

我想在我的android项目中生成我的JUnit测试的代码覆盖率报告,所以我添加了JaCoCo gradle插件.这是我的项目级build.gradle文件:

apply plugin: 'jacoco'

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-beta6'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

subprojects { prj ->
    apply plugin: 'jacoco'

    jacoco {
        toolVersion '0.7.6.201602180812'
    }

    task jacocoReport(type: JacocoReport, dependsOn: 'testDebugUnitTest') {
        group = 'Reporting'
        description = 'Generate Jacoco coverage reports after running tests.'

        reports {
            xml {
                enabled = true
                destination "${prj.buildDir}/reports/jacoco/jacoco.xml"
            }
            html {
                enabled = true
                destination "${prj.buildDir}/reports/jacoco"
            }
        }

        classDirectories = fileTree(
                dir: 'build/intermediates/classes/debug',
                excludes: [
                        '**/R*.class',
                        '**/BuildConfig*',
                        '**/*$$*'
                ]
        )

        sourceDirectories = files('src/main/java')
        executionData = files('build/jacoco/testDebugUnitTest.exec')

        doFirst {
            files('build/intermediates/classes/debug').getFiles().each { file ->
                if (file.name.contains('$$')) {
                    file.renameTo(file.path.replace('$$', '$'))
                }
            }
        }
    }
}

jacoco {
    toolVersion '0.7.6.201602180812'
}

task jacocoFullReport(type: JacocoReport, group: 'Coverage reports') {
    group = 'Reporting'
    description = 'Generates an aggregate report from all subprojects'

    //noinspection GrUnresolvedAccess
    dependsOn(subprojects.jacocoReport)

    additionalSourceDirs = project.files(subprojects.jacocoReport.sourceDirectories)
    sourceDirectories = project.files(subprojects.jacocoReport.sourceDirectories)
    classDirectories = project.files(subprojects.jacocoReport.classDirectories)
    executionData = project.files(subprojects.jacocoReport.executionData)

    reports {
        xml {
            enabled = true
            destination "${buildDir}/reports/jacoco/full/jacoco.xml"
        }
        html {
            enabled = true
            destination "${buildDir}/reports/jacoco/full"
        }
    }

    doFirst {
        //noinspection GroovyAssignabilityCheck
        executionData = files(executionData.findAll { it.exists() })
    }
}

它运行起来很棒./gradlew jacocoFullReport.但遗憾的是,没有报告使用的测试报告(测试RobolectricTestRunner中明显调用的指令未报告为覆盖).没有@RunWith注释的测试或运行MockitoJUnitTestRunner报告覆盖率就好了.

任何帮助将不胜感激,以解决这个问题.

更新1:我注意到我应该使用RobolectricGradleTestRunner.但它没有帮助.

已知问题可能的解决方法 - https://github.com/jacoco/jacoco/pull/288

或者将jacoco版本降级为0.7.1.201405082137

UPDATE

不再需要解决方法.您必须使用gradle版本2.13和jacoco版本0.7.6.201602180812.

更新根目录build.gradle:

buildscript {
    dependencies {
        classpath 'org.jacoco:org.jacoco.core:0.7.6.201602180812'
    }
}

task wrapper( type: Wrapper ) {
  gradleVersion = '2.13'
}

跑 ./gradlew wrapper

更新项目build.gradle:

apply plugin: 'jacoco'

android {
  testOptions {
    unitTests.all {
      jacoco {
        includeNoLocationClasses = true
      }
    }
  }
}

Answer 2

接受的答案有点过时了。这是我们刚刚实施的类似修复。在模块（即 app）build.gradle 中添加：

apply plugin: 'jacoco'

tasks.withType(Test) {
    jacoco.includeNoLocationClasses = true
}

这确实需要 JaCoCo 7.6+，但您可能已经在使用它。

工作室注意事项：

1. 这仅修复了 CLI。如果您使用 JaCoCo 从 Studio 运行覆盖率，则仍不会报告 Robolectric 覆盖率。默认的 IntelliJ Coverage Runner 似乎工作正常。
2. 除非我将 -noverify 添加到 Android JUnit -> VM 选项，否则 Studio 中的测试会间歇性崩溃
