Android Studio中的Jacoco代码覆盖范围

2 回答

  在花了一整天追逐这个问题后，我发现's the problem. Contrary to the examples i'看到testDebug构建生成的文件不是.exec文件@991768_ .

  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的测试覆盖率报告：

  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（默认为应用程序）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> jacoco.gradle

  • Step 2 ：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要理解

  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终端下面运行命令来构建应用程序

  ./gradlew清洁组装

  • 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）

  ./gradlew testFreeDebugUnitTestCoverage

  • Step 5 :

  它应该在终端给出成功消息，现在转到目录

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

  • Step 6: 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！
