Question

我一直试图在一段时间内安静地进行Jacoco测试覆盖。我已经尝试过在这些主题中报告的几种可能的解决方案：

Android test code coverage with JaCoCo Gradle plugin

How do I get a jacoco coverage report using Android gradle plugin 0.10.0 or higher?

我正在使用genymotion在emulatated设备中运行测试。这是我添加到build.gradle：

apply plugin: 'jacoco'

android{       
    jacoco {
        version "0.7.1.201405082137"
    }        
    buildTypes{
        debug{
                    testCoverageEnabled = true
        }
    }
}

jacoco {
    toolVersion "0.7.1.201405082137"
}

要运行它，我会使用

之类的东西

./gradlew clean
./gradlew createFLAVOR_NAMEDebugCoverageReport

相关生成的文件/文件夹是：

/build/intermediates/coverage-instrumented-classes
/build/intermediates/jacoco
/build/outputs/code-coverage/connected/flavors/MyFlavor/coverage.ec

但是，没有@ build / reports / jacoco / test / html / index.html或任何html页面/代码覆盖率报告@ / build / outputs。

我还尝试创建专门的任务来构建覆盖率报告：

def coverageSourceDirs = [
    'src/main/java',
]

task jacocoTestReport(type: JacocoReport, dependsOn: "connectedAndroidTestFLAVOR_NAMEDebug") {
    group = "Reporting"
    description = "Generate Jacoco coverage reports after running tests."
    reports {
        xml.enabled = true
        html.enabled = true
    }
    classDirectories = fileTree(
        dir: './build/intermediates/classes/debug',
        excludes: ['**/R*.class',
                   '**/*$InjectAdapter.class',
                   '**/*$ModuleAdapter.class',
                   '**/*$ViewInjector*.class'
        ])
    sourceDirectories = files(coverageSourceDirs)
    executionData = files("$buildDir/jacoco/connectedAndroidTestMyFlavorDebug.exec")
    // Bit hacky but fixes https://code.google.com/p/android/issues/detail?id=69174.
    // We iterate through the compiled .class tree and rename $$ to $.
    doFirst {
       new File("$buildDir/intermediates/classes/").eachFileRecurse { file ->
            if (file.name.contains('$$')) {
                file.renameTo(file.path.replace('$$', '$'))
            }
        }
    }
}

然后 ./ gradlew clean 和 ./ gradlew jacocoTestReport 。输出与上面相同，因此，没有带覆盖报告的html页面或任何其他覆盖文件。

我目前正在使用带有最新gradle版本的Android Studio v1.0.2。我相当陌生，所以我可能会遗漏一些基本的东西。

Answer 1

在花了一整天追逐这个问题后，我发现了什么问题。与我看到的示例相反，testDebug构建生成的文件不是.exec文件@ $ buildDir / jacoco / testDebug.exec 。

使用我的gradle和studio版本生成的文件是.ec @ build / outputs / code-coverage / connected / flavors / myFlavor / coverage.ec

我没有找到任何与此相关的相关信息。然而，这可能是最近的更改，通过创建自定义JacocoReport任务并相应地更改executionData变量我已经解决了问题。这是我的实施：

task jacocoTestReport(type: JacocoReport) {

  def coverageSourceDirs = [
        'src/main/java'
  ]

  group = "Reporting"
  description = "Generates Jacoco coverage reports"
  reports {
      xml{
          enabled = true
          destination "${buildDir}/reports/jacoco/jacoco.xml"
      }
      csv.enabled false
      html{
          enabled true
          destination "${buildDir}/jacocoHtml"
      }
  }

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

  sourceDirectories = files(coverageSourceDirs)
  additionalSourceDirs = files(coverageSourceDirs)
  executionData = files('build/outputs/code-coverage/connected/flavors/smartcompanion/coverage.ec')
}

使用Jacoco和Android Flavors测试覆盖率报告：

让我们考虑一下名为“免费”和“付费”的口味

Step1 ：在项目模块目录（默认为app）中创建文件jacoco.gradle，其中存在build.gradle，它应该在build.gradle文件旁边。目录结构如下图所示

app＆gt; jacoco.gradle
第2步：在我们在步骤1中创建的文件中粘贴下面的代码，代码有自解释的注释以便理解

apply plugin: 'jacoco'

jacoco {
    toolVersion = "0.7.5.201505241946"
}
project.afterEvaluate {
    // Grab all build types and product flavors
    def buildTypes = android.buildTypes.collect { type ->
        type.name
    }
    def productFlavors = android.productFlavors.collect { flavor ->
        flavor.name
    }
    // When no product flavors defined, use empty
    if (!productFlavors) productFlavors.add('')

    //iterate over the flavors

    productFlavors.each {

        productFlavorName ->
//iterate over build types like debug,release,prod etc.
        buildTypes.each {

            buildTypeName ->
                //sourceName — e.g. freeDebug ,sourcePath — e.g. free/debug
            def sourceName, sourcePath
            if (!productFlavorName) {
                sourceName = sourcePath = "${buildTypeName}"
            } else {
                sourceName = "${productFlavorName}${buildTypeName.capitalize()}"
                sourcePath = "${productFlavorName}/${buildTypeName}"
            }
                // testTaskName —  e.g. testFreeDebugtest task that the coverage task depends on,
            def testTaskName = "test${sourceName.capitalize()}UnitTest"
            // Create coverage task of form 'testFlavorTypeCoverage' depending on 'testFlavorTypeUnitTest'
            task "${testTaskName}Coverage" (type:JacocoReport, dependsOn: "$testTaskName") {
                group = "Reporting"
                description = "Generate Jacoco coverage reports on the ${sourceName.capitalize()} build."
                classDirectories = fileTree(
                        dir: "${project.buildDir}/intermediates/classes/${sourcePath}",
                        excludes: [
                                '**/R.class',
                                '**/R$*.class',
                                '**/*$ViewInjector*.*',
                                '**/*$ViewBinder*.*',
                                '**/BuildConfig.*',
                                '**/Manifest*.*'
                        ]
                )
                def coverageSourceDirs = [
                        "src/main/java",
                        "src/$productFlavorName/java",
                        "src/$buildTypeName/java"
                ]
                additionalSourceDirs = files(coverageSourceDirs)
                sourceDirectories = files(coverageSourceDirs)
                executionData = files("${project.buildDir}/jacoco/${testTaskName}.exec")
                reports {
                    //enables and disable the type of file you need
                    xml.enabled = false
                    html.enabled = true
                }
            }
        }
    }
}

步骤3：在android studio终端的命令下运行以构建应用程序

./ gradlew clean assemble
步骤4：on build sucessfull，运行以下命令生成测试报告（将字符串“testFreeDebugUnitTestCoverage”更改为您的特定flavor / build类型，例如对于付费版本命令将为./gradlew testPaidDebugUnitTestCoverage）< / p>
./ gradlew testFreeDebugUnitTestCoverage
第5步：

它应该在终端中给出成功消息，现在转到目录

>app > build > reports >jacoco >${testName} >look for html or xml file report file

第6步：现在您可以在浏览器中打开并查看html测试覆盖率文件

最好的运气!!!
