Jacoco Gradle中的最小代码覆盖率阈值

Question

如何在Jacoco Gradle中设置最小代码覆盖率？

如果不满足,我希望构建失败.

Answer 1

该功能现已推出.您只需要应用Gradle JaCoCo插件并定义覆盖验证,如下所示:

apply plugin: 'jacoco'

jacocoTestCoverageVerification {
    violationRules {
        rule {
            limit {
                minimum = 0.7
            }
        }
    }
}

// to run coverage verification during the build (and fail when appropriate)
check.dependsOn jacocoTestCoverageVerification

最后一行非常重要,因为除非您明确运行jacocoTestCoverageVerification任务,否则构建将不会失败.

有关您可能添加的检查类型的更多信息,请参阅插件的文档.

在 Android 应用程序中，此配置有效：

项目：构建.gradle

buildscript {
    repositories {
        google()
        jcenter()
        maven { url 'https://plugins.gradle.org/m2/' }
    }
    dependencies {
        classpath "com.android.tools.build:gradle:3.1.4"
        classpath "org.jacoco:org.jacoco.core:0.8.2"
    }
}

应用程序：构建.gradle

ext.jacoco_version = '0.8.2'
def configDir = "${project.rootDir}/config"
def reportDir = "${project.buildDir}/reports"
def mainSrc = "$project.projectDir/src/main/java"
def fileFilter = ['**/R.class', '**/R$*.class', '**/BuildConfig.*', '**/Manifest*.*', '**/*Test*.*', 'android/**/*.*']
def debugTree = fileTree(dir: "$project.buildDir/intermediates/classes/debug", excludes: fileFilter)
//Jacoco jacocoTestReport
apply plugin: 'jacoco'
jacoco.toolVersion = jacoco_version
task jacocoTestReport(type: JacocoReport, dependsOn: 'testDebugUnitTest') {
    reports {
        xml.enabled = false
        html.enabled = true
    }
    sourceDirectories = files([mainSrc])
    classDirectories = files([debugTree])
    executionData = fileTree(dir: project.buildDir, includes: [
            'jacoco/testDebugUnitTest.exec', 'outputs/code-coverage/connected/*coverage.ec'
    ])
}
task jacocoTestCoverageVerification(type: JacocoCoverageVerification, dependsOn: 'jacocoTestReport') {
    sourceDirectories = files([mainSrc])
    classDirectories = files([debugTree])
    executionData = files("${buildDir}/jacoco/testDebugUnitTest.exec")
    violationRules {
        failOnViolation = true
        rule {
            limit {
                minimum = 0.7
            }
        }
    }
}

我们可以在命令行中执行它：

./gradlew jacocoTestCoverageVerification

我使用了 gradle 包装器 4.4。

gradle Jacoco插件目前不支持此功能.见悬而未决的问题在这里.

但是,可以编写一个自定义任务来解析Jacoco报告,并根据coverage覆盖构建失败.请参阅此处了解实现此目的的一种方法.
