在android studio 2.3中使用espresso和ui automator生成测试覆盖率报告

Question

应用程序级别的Build.Gradle

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
apply plugin: 'jacoco'
jacoco {
    toolVersion = "0.7.6.201602180812"
    reportsDir = file("$buildDir/customJacocoReportDir")
}
def coverageSourceDirs = [
        'src/main/java',
]
task jacocoTestReport(type: JacocoReport, dependsOn: "connectedDebugAndroidTest") {
    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'

            ])
    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('$$', '$'))
            }
        }
    }
}

可以在build.gradle文件中将testCoverageEnabled参数设置为true来生成测试覆盖率报告：

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

然后使用：

./gradlew connectedCheck

./gradlew createDebugCoverageReport

/build/outputs/reports/coverage/debug/
