使用JaCoCo Gradle插件的Android測試代碼覆蓋率

Question

我是Gradle和Android測試的新手，但我已經將我的Android項目轉換為使用Gradle構建。

現在，我正在嘗試使用Gradle的JaCoCo插件執行Android項目的測試覆蓋。

我已將以下內容添加到build.gradle文件中：

apply plugin: 'jacoco'

當我運行“gradle jacocoTestReport”時出現以下錯誤：

Task 'jacocoTestReport' not found in root project '<project name>'.

從文檔我應該也應用插件'java'但它與插件'android'沖突。

有沒有解決的辦法？

提前致謝。

以下是我使用Jacoco ：

buildscript {
  repositories {
    mavenLocal()
    mavenCentral()
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:0.12.+'
    classpath 'org.robolectric:robolectric-gradle-plugin:0.11.+'
  }
}

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

android {
  compileSdkVersion 20
  buildToolsVersion "20.0.0"

  defaultConfig {
    applicationId "YOUR_PACKAGE_NAME"
    minSdkVersion 10
    targetSdkVersion 20
    testHandleProfiling true
    testFunctionalTest true
  }
  buildTypes {
    debug {
      testCoverageEnabled false
    }
    release {
      runProguard false

robolectric {

jacoco {

}

// Define coverage source.
// If you have rs/aidl etc... add them here.
def coverageSourceDirs = [

task jacocoTestReport(type: JacocoReport, dependsOn: "connectedDebugAndroidTest") {
  group = "Reporting"
  description = "Generate Jacoco coverage reports after running tests."
  reports {
    xml.enabled = true
    html.enabled = true
  }

                 '**/*$InjectAdapter.class',
                 '**/*$ModuleAdapter.class',
                 '**/*$ViewInjector*.class'
      ])
  sourceDirectories = files(coverageSourceDirs)
  executionData = files("$buildDir/jacoco/testDebug.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('$$', '$'))
      }
    }
  }
}


dependencies {
  androidTestCompile('junit:junit:4.11') {
    exclude module: 'hamcrest-core'
  }
  androidTestCompile('org.robolectric:robolectric:2.3') {
    exclude module: 'classworlds'

    exclude module: 'wagon-http-shared'
    exclude module: 'wagon-provider-api'

  }
}

上述代碼還包含https://code.google.com/p/android/issues/detail?id=69174的解決方法。

我正在使用JaCoCo進行使用RoboGuice，Butterknife和Robolectric的項目。 我能夠使用@Hieu Rocker的解決方案來設置它，但是有一些小缺點，即在我們的項目中，我們使用flavor並對這些flavor進行一些額外的測試以及每個的額外java代碼。 我們還使用不同的構建類型。 因此，依賴“testDebug”任務的解決方案還不夠好。 這是我的解決方案：在app模塊中的build.gradle中添加

apply from: '../app/jacoco.gradle'

然后在app模塊中創建一個jacoco.gradle文件，其中包含以下內容：

apply plugin: 'jacoco'

    jacoco {
        toolVersion "0.7.1.201405082137"
    }

    def getFlavorFromVariant(String variantName) {
        def flavorString = variantName.replaceAll(/(.*)([A-Z].*)/) { all, flavorName, buildTypeName ->
           flavorName
        }
        return flavorString;
    }

    def getBuildTypeFromVariant(String variantName) {
        def buildTypeString = variantName.replaceAll(/(.*)([A-Z].*)/) { all, flavorName, buildTypeName ->
            "${buildTypeName.toLowerCase()}"
        }
        return buildTypeString;
    }

    def getFullTestTaskName(String variantName) {
        return "test${variantName.capitalize()}UnitTest";
    }

    android.applicationVariants.all { variant ->
        def variantName = variant.name;
        def flavorFromVariant = getFlavorFromVariant("${variantName}");
        def buildTypeFromVariant = getBuildTypeFromVariant("${variantName}");
        def testTaskName = getFullTestTaskName("${variantName}")

        task ("jacoco${variantName.capitalize()}TestReport", type: JacocoReport, dependsOn: testTaskName) {
            group = "Reporting"
            description = "Generate JaCoCo coverage reports after running tests for variant: ${variantName}."
            reports {
                xml.enabled = true
                html.enabled = true
            }

            classDirectories = fileTree(
                    dir: "./build/intermediates/classes/${flavorFromVariant}/${buildTypeFromVariant}",
                    excludes: ['**/R*.class',
                               '**/*$InjectAdapter.class',
                               '**/*$ModuleAdapter.class',
                               '**/*$ViewInjector*.class'
                    ]
            )

            logger.info("Configuring JaCoCo for flavor: ${flavorFromVariant}, buildType: ${buildTypeFromVariant}, task: ${testTaskName}");

            def coverageSourceDirs = [
                    '../app/src/main/java',
                    "../app/src/${flavorFromVariant}/java"
            ]
            sourceDirectories = files(coverageSourceDirs)
            executionData = files("$buildDir/jacoco/${testTaskName}.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('$$', '$'))
                    }
                }
            }
        }
    }

您可以從命令行執行它，如下所示：

.gradlew jacocoFlavor1DebugTestReport

要么

.gradlew jacocoOtherflavorPrereleaseTestReport

在我們的項目中，我們使用一個約定，不要在flavor和build類型名稱中使用大寫字母，但如果你的項目不遵循這個約定，你只需更改getFlavorFromVariant（..）和getBuildTypeFromVariant（..）函數

希望這有助於某人

您可以嘗試使用此Gradle插件： https ： //github.com/arturdm/jacoco-android-gradle-plugin

這里的答案還有一點https://stackoverflow.com/a/32572259/1711454 。

Answer 4

您是否嘗試添加以下內容：

jacocoTestReport {
   group = "Reporting"
   description = "Generate Jacoco coverage reports after running tests."
   additionalSourceDirs = files(sourceSets.main.allJava.srcDirs)
}

然后運行./gradlew jacocoTestReport而不是運行./gradlew test jacocoTestReport 。

如果一切順利，您應該在build/reports/jacoco/test/html/index.html找到測試結果。
