tomcat - Jacoco 代码覆盖率在 Tomcat 上收集 0% : JDK 7 + Gradle 1. 5 + Jacoco 0.6.2 + Tomcat 7.0.29

Question

我有以下环境:JDK 7 + Gradle 1.5 + Jacoco 0.6.2 + Tomcat 7.0.29(我的 GIST 中的完整代码 https://gist.github.com/marcellodesales/5496686 )。

以下 build.gradle 是我当前的构建脚本，我尝试从中运行以 Rest-Assured 为 Restful API 编写的集成测试的代码覆盖率。我尝试了 Jacoco 插件 (org.ajoberstar:gradle-jacoco:0.3.0)，我尝试使用 Jars 中的 Jacoco 并尝试使用 Agent，但它甚至没有启动(https://stackoverflow.com/a/16035811/433814)。

尝试使用插件后，我决定从 Jars 手动运行 Jacoco。可以在 https://github.com/marcellodesales/gradle-rest-assured-selenium-jacoco 下载完整的应用程序.这是添加 JVM 选项以添加 JVM 选项的更改的脚本片段:

task integrationTest(type: Test, dependsOn: jar, description: 'Runs the integration tests.', group: 'verification') {
  testClassesDir = sourceSets.integrationTest.output.classesDir
  classpath = sourceSets.integrationTest.runtimeClasspath
  systemProperties['jar.path'] = jar.archivePath

  // use JaCoCo agent to record execution coverage data
  jvmArgs "-javaagent:$configurations.jacoco.asPath=destfile=$buildDir/jacoco-int.exec"
}
check.dependsOn integrationTest

integrationTest.doFirst {
  println 'Starting the embedded tomcat server'
  tasks.tomcatRun.daemon = true
  tasks.tomcatRun.execute()
}

integrationTest.doLast {
  println 'Stopping the embedded tomcat server'
  tasks.tomcatStop.execute()
}

Answer 1

在您的示例代码中，您将构建脚本配置为运行 integTests 的覆盖率而不是生产代码。是要为与tomcat服务器通信的API收集覆盖率数据，还是要为tomcat上运行的代码收集覆盖率数据。对于后者，您必须检测在 tomcat jvm 中执行的代码，而不是 integTest 代码。因此，您必须将 javaagent 设置添加到“tomcatRun”任务。

希望对您有所帮助，
