Android将单元测试覆盖率添加到声纳中

Question

我有Sonar分析的Android项目.我看到了所有问题但没有通过单元测试覆盖.我尝试了很多东西,但仍然无法使其正常工作.当我调用'gradlew createDebugCoverageReport'时,它将在build/reports/coverage/debug中创建包含大量文件(如report.xml和index.html)的目录,其中包含测试覆盖率数据.但在Coars的Coverage下,我得到的信息是"此组件没有覆盖详细信息".我怎样才能让它发挥作用？

命令序列:

gradlew clean assemble
gradlew createDebugCoverageReport
gradlew sonarRunner

的build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "cz.meteocar.unit"
        minSdkVersion 16
        targetSdkVersion 20
        versionCode 3
        versionName "1.0.2"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

            }
            debug {
                debuggable true
                testCoverageEnabled = true
            }


        }
    }


apply plugin: 'sonar-runner'

sonarRunner {
      sonarProperties {
        property "sonar.host.url", "http://localhost:9000" // Address of Sonar         server
        property "sonar.sources", "src/main/java" // Sources
        property "sonar.projectName", "Meteocar" // Name of your project
        property "sonar.projectVersion", "1.0.2" // Version of your project
        property "sonar.projectDescription", "Sonar" // Description of your project
        property "sonar.junit.reportsPath", "build/reports/coverage/"
    }
}

Answer 1

您可以使用Jacoco覆盖结果.它适用于sonar:

1.安装Android插件SonarQube

2.添加jacoco plugin并创建一个gradle taskon Gradle来生成coverage文件,如:

apply plugin: 'jacoco'

jacoco {
    version "0.7.1.201405082137"
}

task jacocoTestReport(type: JacocoReport, dependsOn: "testDebugUnitTest") {
    group = "Reporting"
    description = "Generate Jacoco coverage reports after running tests."
    reports {
        xml.enabled = true
        html.enabled = true
    }
    classDirectories = fileTree(
            dir: 'build/intermediates/classes/debug/com/yourapppackagename',
            excludes: ['**/R.class',
                       '**/R$*.class',
                       '**/BuildConfig.*',
                       '**/Manifest*.*'])
    sourceDirectories = files('src/main/java')
    executionData = files('build/jacoco/testDebugUnitTest.exec')
    doFirst {
        files('build/intermediates/classes/debug').getFiles().each { file ->
            if (file.name.contains('$$')) {
                file.renameTo(file.path.replace('$$', '$'))
            }
        }
    }
}

3. sonar.properties在根目录上创建文件并包含 coverage文件路径:

sonar.jacoco.reportPath=sdk/build/jacoco/testDebugUnitTest.exec
sonar.junit.reportsPath=sdk/build/test-results/debug

4.Run jacoco gradle task:

 ./gradlew clean assembleDebug jacocoTestReport

5.Run sonar analyses
