使用gradle从android测试代码覆盖到声纳

Question

i have to set up code coverage report on my android tests and then publish them in sonar. I have read that there are no tools and plugins which can do it. I am using gradle scripts and i try jacoco plugin, cobertura, but no results. Is it any ways to resolve it? Also i tried to do like here Gradle jacoco code coverage - Then publish/show in Jenkins

Example of build.gradle with code-coverage and sonar

apply plugin: 'com.android.application'

    android {

        compileSdkVersion 20
        buildToolsVersion '20.0.0'
        defaultConfig {
            applicationId 'com.example.coverage'
            minSdkVersion 11
            targetSdkVersion 19
            versionCode 1
            versionName '1.0'
            testHandleProfiling true
            testFunctionalTest true

        }
        buildTypes {
            debug {
                testCoverageEnabled true
            }
            release {
                runProguard false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
        compileOptions {

            apply plugin: 'sonar-runner'
        }

        packagingOptions {
            exclude 'META-INF/DEPENDENCIES.txt'
            exclude 'META-INF/LICENSE.txt'
            exclude 'META-INF/NOTICE.txt'
            exclude 'META-INF/NOTICE'
            exclude 'META-INF/LICENSE'
            exclude 'META-INF/DEPENDENCIES'
            exclude 'META-INF/notice.txt'
            exclude 'META-INF/license.txt'
            exclude 'META-INF/dependencies.txt'
            exclude 'META-INF/LGPL2.1'
            exclude 'META-INF/services/javax.annotation.processing.Processor'
            exclude 'LICENSE.txt'
        }
    }

    sonarRunner {

        sonarProperties {

            property "sonar.projectKey", "coverage-example"
            property "sonar.projectName", "Coverage Example"
            property "sonar.projectVersion", "1.0"

            property "sonar.sources", "src/main/java"
            property "sonar.binaries", "build"
            property "sonar.test", "src/androidTest/java"

            property "sonar.profile", "Sonar way"
            property "sonar.language", "java"
            property "sonar.sourceEncoding", "UTF-8"

            property "sonar.dynamicAnalysis", "reuseReports"

            property "sonar.junit.reportsPath", "build/outputs/reports/coverage/debug"
            property "sonar.cobertura.reportPath", "build/outputs/reports/coverage/debug/cobertura.xml"
            property "sonar.java.coveragePlugin", "cobertura"

            property "sonar.host.url", "http://localhost:9099"
        }
    }

Now run

gradlew clean assembleDebug createDebugCoverageReport

Now you will be able to see a xml containing the code coverage report in this directory

app/build/outputs/reports/coverage/debug/report.xml

Now before we run the sonar task, we have to convert the report.xml something that sonar can read, it will use this done in python script that performs the conversion of this file to the format that the plugin sonar cobertura can use it.

Link the script on github

python cover2cover.py app/build/outputs/reports/coverage/debug/report.xml src/main/java > app/build/outputs/reports/coverage/debug/cobertura.xml && cp app/build/outputs/androidTest-results/connected/* app/build/outputs/reports/coverage/debug/

Now run

gradlew sonarRunner
