我已经为不同的域类和服务类（Webservice）编写了单元测试。现在我想使用JoCoCo生成代码覆盖率报告。 因此我们的想法是在我们执行某些操作（例如手动使用网站或启动Junit测试）时，了解我在weblogic上运行的代码的代码覆盖率。 我已在我的weblogic服务器中部署了ear文件。如何将JoCoCo连接到weblogic服务器？ 你能不能告诉我如何用weblogic服务器配置JaCoCo并生成报告。

如果您需要获取针对Java代码的测试的代码覆盖率，那么JaCoCo是一个非常好的选择，因为您不需要事先检测代码，它将在测试期间即时执行
将JaCoCo附加到Weblogic JVM：
JaCoCo收集器将其自身作为代理附加到JVM并持续收集代码覆盖工具。我们需要添加JVM参数来设置它。
步骤1： 为此，请编辑 setDomainEnv.cmd 或 setDomainEnv.sh 文件以添加以下参数：
set JACOCO_PROPERTIES=-javaagent:c:/tools/jacoco-0.7.1-20140326.062324-3/lib/jacocoagent.jar=destfile=c:/temp/jacoco.exec,output=file,address=,includes=com.package
在同一文件中，将其添加到EXTRA_JAVA_PROPERTIES环境变量：
set
EXTRA_JAVA_PROPERTIES=-Dcommon.components.home=%COMMON_COMPONENTS_HOME%
-Djrf.version=11.1.1 -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.Jdk14Logger
-Ddomain.home=%DOMAIN_HOME% -Djrockit.optfile=%COMMON_COMPONENTS_HOME%\modules\oracle.jrf_11.1.1\jrocket_optfile.txt
-Doracle.server.config.dir=%ORACLE_DOMAIN_CONFIG_DIR%\servers\%SERVER_NAME%
-Doracle.domain.config.dir=%ORACLE_DOMAIN_CONFIG_DIR% -Digf.arisidbeans.carmlloc=%ORACLE_DOMAIN_CONFIG_DIR%\carml -Digf.arisidstack.home=%ORACLE_DOMAIN_CONFIG_DIR%\arisidprovider -Doracle.security.jps.config=%DOMAIN_HOME%\config\fmwconfig\jps-config.xml
-Doracle.deployed.app.dir=%DOMAIN_HOME%\servers\%SERVER_NAME%\tmp_WL_user
-Doracle.deployed.app.ext=- -Dweblogic.alternateTypesDirectory=%ALT_TYPES_DIR% -Djava.protocol.handler.pkgs=%PROTOCOL_HANDLERS% %WLS_JDBC_REMOTE_ENABLED% %**JACOCO_PROPERTIES**%
%EXTRA_JAVA_PROPERTIES%
步骤2： 重新启动Weblogic Server 因为JaCoCo将自己附加到JVM，所以您需要重新启动Weblogic服务器。使用startWeblogic.sh或startWeblogic.cmd再次启动JVM后，您将看到将创建destfile = c：/temp/jacoco.exec列出的文件位置。最初它将为空，但在关闭JVM时它将被填充。
第3步：测试您的应用程序 连接JaCoCo代理后，部署应用程序并运行集成测试。 JaCoCo将即时检测代码并收集指令级和分支级覆盖信息。
第4步：生成报告

单元测试不在应用程序服务器上运行。事实上，Application Server资源被认为是单元测试的外部依赖，应该使用模拟框架进行模拟。因此，只有在单元测试运行时才能生成代码覆盖率报告。
您所指的可能是自动功能测试。我不知道这种测试的覆盖率报告工具。
