Android的测试code覆盖率JaCoCo摇篮插件 [英] Android test code coverage with JaCoCo Gradle plugin

问题描述

我是新来的摇篮和Android测试，但我已经将我的Andr​​oid项目建立与摇篮。

I'm new to Gradle and Android testing but I've already converted my Android project to build with Gradle.

现在我想执行与摇篮的JaCoCo插件的Andr​​oid项目的测试覆盖率。

Now I'm trying to perform test coverage of an Android project with Gradle's JaCoCo plugin.

我添加以下到我的build.gradle文件：

I've added the following to my build.gradle file:

apply plugin: 'jacoco'

当我运行摇篮jacocoTestReport以下错误：

And when I run "gradle jacocoTestReport" the following error:

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

从文档我应该也适用插件的Java，但它的插件'机器人'冲突。

From the documentation I'm supposed to also apply plugin 'java' but it conflicts with plugin 'android'.

有没有解决的办法吗？

在此先感谢。

推荐答案

下面是我如何使用 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
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
  }
  jacoco {
    version "0.7.1.201405082137"
  }
  packagingOptions {

}

robolectric {

  exclude '**/espresso/**/*.class'

  maxHeapSize "2048m"
}

jacoco {

}

// Define coverage source.
// If you have rs/aidl etc... add them here.
def coverageSourceDirs = [
    'src/main/java',
]

task jacocoTestReport(type: JacocoReport, dependsOn: "testDebug") {
  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/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: 'maven-artifact'
    exclude module: 'maven-artifact-manager'
    exclude module: 'maven-error-diagnostics'

    exclude module: 'wagon-http-shared'
    exclude module: 'wagon-provider-api'
    exclude group: 'com.android.support', module: 'support-v4'
  }
}

以上code还含有一种变通方法<一href="https://$c$c.google.com/p/android/issues/detail?id=69174">https://$c$c.google.com/p/android/issues/detail?id=69174.
