Gradle：如何使用jacoco为集成测试生成覆盖报告

Question

我是格雷德尔的新手。我正在使用下面的代码。但是它会生成单元测试用例的覆盖率。但它不是为集成测试用例生成的。我在src/test/java包中有测试类。

test {
    dependsOn jettyRunWar
    ignoreFailures true
    finalizedBy jettyStop
}

apply plugin: 'jacoco'

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

Answer 1

使用Gradle 5.4.1（现在是5.5.1)，我能够在任何测试任务后获得报告，目前我有test和integrationtest任务。

Edit3:修正了只执行部分测试任务时的潜在bug

• 不要在dolast/doFirst块中配置ExecutionData，这是我的错误。欲了解更多信息，请查看此gradle github Ticket
• 添加了更谨慎的替代方法（同样不在dolast/doFirst块中）executiondata{tasks.withtype（Test）.findall{it.jacoco.destinationfile.exists（）}*.jacoco.destinationfile}

Edit2:解决方案是一样的，我只是调整了一下

null

jacocoTestReport {
    // The JaCoCo plugin adds a JacocoTaskExtension extension to all tasks of type Test.
    // Use task state to include or not task execution data
    // https://docs.gradle.org/current/javadoc/org/gradle/api/tasks/TaskState.html
    // This declaration will be used as a closure, notice there no wrapping parenthesis
    executionData tasks.withType(Test).findAll { it.state.executed }

    // If the above instruction really don't work, there maybe some things that intervene in the process, in this case, you may be a bit more lucky with this instruction
    // executionData { tasks.withType(Test).findAll { it.jacoco.destinationFile.exists() }*.jacoco.destinationFile }

    reports {
        xml.enabled true
        xml.destination(file("${jacoco.reportsDir}/all-tests/jacocoAllTestReport.xml"))
        html.enabled true
        html.destination(file("${jacoco.reportsDir}/all-tests/html"))
    }
}

同样的技巧也可以应用于Sonarqube任务：

sonarqube {
    group = "verification"
    properties {
        // https://jira.sonarsource.com/browse/MMF-1651
        property "sonar.coverage.jacoco.xmlReportPaths", jacocoTestReport.reports.xml.destination
        properties["sonar.junit.reportPaths"] += integrationTest.reports.junitXml.destination
        properties["sonar.tests"] += sourceSets.integrationTest.allSource.srcDirs
        // ... other properties
    }
}

更老但很管用的答案。同样，使用上述知识(Test的任务由JacoCotaskExtension扩展），可以用Test.jacoco.destinationFile和IntegrationTest.jacoco.destinationFile替换ExecutionData的手动文件配置。

// Without it, the only data is the binary data, 
// but I need the XML and HTML report after any test task
tasks.withType(Test) {
    finalizedBy jacocoTestReport
}

// Configure the report to look for executionData generated during the test and integrationTest task
jacocoTestReport {
    executionData(file("${project.buildDir}/jacoco/test.exec"),
                  file("${project.buildDir}/jacoco/integrationTest.exec"))
    reports {
        // for sonarqube
        xml.enabled true
        xml.destination(file("${project.buildDir}/reports/jacoco/all-tests/jacocoAllTestReport.xml"))
        // for devs
        html.enabled true
        html.destination file("${project.buildDir}/reports/jacoco/all-tests/html")
    }
}


sonarqube {
    group = "verification"
    properties {
        // https://jira.sonarsource.com/browse/MMF-1651
        property "sonar.coverage.jacoco.xmlReportPaths", ${project.buildDir}/test-results/integrationTest"
        properties["sonar.junit.reportPaths"] += "${project.buildDir}/test-results/integrationTest"
        properties["sonar.tests"] += sourceSets.integrationTest.allSource.srcDirs
        // ... other properties
    }
}

project.tasks["sonarqube"].dependsOn "jacocoTestReport"
