Android将单元测试覆盖率添加到声纳中

Question

我有一个由 Sonar 分析的 Android 项目。我看到了所有问题，但单元测试没有覆盖。我尝试了很多东西，但仍然无法正常工作。当我调用“gradlew createDebugCoverageReport”时，它会在 build/reports/coverage/debug 中创建目录，其中包含许多文件，例如 report.xml 和 index.html，其中包含测试覆盖率数据。但是在覆盖范围下的声纳中，我收到类似“此组件没有覆盖详细信息”的消息。我怎样才能让它工作？

命令序列：

gradlew clean assemble
gradlew createDebugCoverageReport
gradlew sonarRunner

构建.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/"
    }
}



dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')

Answer 1

您可以使用Jacoco 获取覆盖结果。它适用于sonar：

1.在SonarQube上安装Android插件

2.添加jacoco plugin并在Gradle上创建gradle task以生成coverage文件，smth like：

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.在你的根目录下创建sonar.properties文件并include覆盖文件路径：

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

4.运行jacoco gradle task:

 ./gradlew clean assembleDebug jacocoTestReport

5.运行sonar analyses
