jacocoTestReport任务未生成

Question

Android Studio 3.1 Canary 8
Build #AI-173.4529993, built on January 6, 2018
JRE: 1.8.0_152-release-1024-b01 amd64

我正在尝试使用jacoco来生成代码覆盖率.但是,当我运行命令时,./gradlew tasks我看不到任何调用的任务jacocoTestReport.

我尝试运行任务时遇到以下错误./gradlew jacocoTestReport:

在根项目'EnumSample'中找不到任务'jacocoTestReport'

这是我的build.gradlew文件:

apply plugin: 'com.android.application'
apply plugin: 'jacoco'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "me.androidbox.enumsample"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            testCoverageEnabled true
        }
    }
}

jacoco {
    toolVersion "0.8.0"
}

task jacocoTestReport(type: JacocoReport) {
    executionData fileTree(project.rootDir.absolutePath).include("**/build/jacoco/*.exec")

    subprojects.each {
        sourceSets it.sourceSets.main
    }

    reports {
        xml.enabled true
        html.enabled false
        csv.enabled false
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.0.2'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

我试图清理并重建项目.但是,报告任务不存在.

非常感谢任何建议.

有两件事：

• 您需要为要测试的构建类型启用代码覆盖支持。您build.gradle应该包括以下内容（您已经包括在内）：

  android { 
      ... 
      buildTypes { 
          debug { 
              testCoverageEnabled = true 
          } 
          ... 
      } 
      ... 
  }
  

  • 要生成报告，请运行gradle testBlueDebugUnitTestCoverage，您将在“build/reports/jacoco/testBlueDebugUnitTestCoverage/”中看到它们
  • 这是一个gitHub 示例

• 使用生成 JaCoCo 报告的Gradle 插件：

  像这样设置它：

  buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.vanniktech:gradle-android-junit-jacoco-plugin:0.11.0'
      }
  }
  
  apply plugin: 'com.vanniktech.android.junit.jacoco'
  

此处报告的另一个问题解决方案：

task jacocoTestReport(type: JacocoReport, dependsOn: "testDebug") { 
    group = "Reporting" 
    description = "Generate Jacoco coverage reports after running tests." 
    reports { 
        xml.enabled = false 
        html.enabled = true 
    } 
    classDirectories = fileTree( 
            dir: './build/classes/debug', 
            excludes: ['**/R.class', 
                       '**/R$*.class', 
                       '**/*$InjectAdapter.class', 
                       '**/*$ModuleAdapter.class', 
                       '**/*$ViewInjector*.class' 
            ]) 
    sourceDirectories = files(coverageSourceDirs) 
    executionData = files('build/jacoco/testDebug.exec') 

    renamedFilesMap = [:] 

    // Hacky fix for issue: https://code.google.com/p/android/issues/detail?id=69174. 
    // Rename files with '$$' before generating report, and then rename back after 
    doFirst { 
        new File('build/classes/debug').eachFileRecurse { file -> 
            if (file.name.contains('$$')) { 
                oldPath = file.path 
                newPath = oldPath.replace('$$', '$') 
                file.renameTo(newPath) 
                renamedFilesMap[newPath] = oldPath 
            } 
        } 
    } 
    doLast { 
        renamedFilesMap.each() { 
            newPath, oldPath -> 
                new File(newPath).renameTo(oldPath) 
        } 
    } 

}

Answer 2

您正在搜索要执行的错误任务。通过执行，./gradlew tasks您将能够找到创建Flavor CoverageReport任务：

执行./gradlew createDevDebugCoverageReport了您在问题中提到的设置后，我能够在/app/build/reports/dev/debug目录中找到生成的报告。

Answer 3

使用jacoco报告时,我们需要注意以下几点:

在app/build.gradle中启用测试覆盖率

android {
    ...
    buildTypes {
        debug {
            testCoverageEnabled true
        }
        ...
    }
}

为jacoco报告创建任务

apply plugin: 'jacoco'

task jacocoTestReport(type: JacocoReport, dependsOn: 'testDebugUnitTest') {

    reports {
        xml.enabled = true
        html.enabled = true
    }

    def fileFilter = ['**/R.class', '**/R$*.class', '**/BuildConfig.*', '**/Manifest*.*', '**/*Test*.*', 'android/**/*.*']
    def debugTree = fileTree(dir: "${buildDir}/intermediates/classes/debug", excludes: fileFilter)
    def mainSrc = "${project.projectDir}/src/main/java"

    sourceDirectories = files([mainSrc])
    classDirectories = files([debugTree])
    executionData = files("${buildDir}/jacoco/testDebugUnitTest.exec")
}

jacoco报告的Gradle命令

./gradlew clean jacocoTestReport

在这里找到jacoco报告

成功执行jacocoTestReport后生成的jacoco报告路径.

应用程序/编译/报告/报道/调试/ index.html的

此外,我已经创建了一个Android jacoco相关的示例存储库,您可以在其中查看.

https://github.com/jiteshmohite/JacocoAndroidSample

另外,请确保您在应用程序目录中运行Gradle命令.

尝试上述示例存储库以供参考.我创造了这个没有复杂性的东西,所以每个人都可以去使用它.
