我有一个maven多模块项目。
root:
moduleA/ # no unit tests
moduleB/ # no unit tests
moduleC/ # no unit tests
tests/ # All unit tests, since depends on modules A, B and C
所有测试都在单个模块中,称为tests /,所有代码都在单独的模块中。
我有办法获得代码覆盖吗?

有一种方法可以实现这一目标。神奇的是创建一个组合的jacoco.exec文件并分两步完成。我的pom:
<properties>
...
<jacoco.overall.exec>${maven.multiModuleProjectDirectory}/target/jacoco_analysis/jacoco.exec</jacoco.overall.exec>
</properties>
<build>
<pluginManagement>
<plugins>
...
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.8</version>
<configuration>
<destFile>${jacoco.overall.exec}</destFile>
<dataFile>${jacoco.overall.exec}</dataFile>
</configuration>
</plugin>
...
</plugins>
</pluginManagement>
</build>
<profiles>
<profile>
<id>runTestWithJacoco</id>
<activation>
<property>
<name>runTestWithJacoco</name>
<value>true</value>
</property>
</activation>
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<executions>
<execution>
<id>default-prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<append>true</append>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
<profile>
<id>createJacocoReport</id>
<activation>
<property>
<name>createJacocoReport</name>
<value>true</value>
</property>
</activation>
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<executions>
<execution>
<id>default-report</id>
<phase>validate</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
</profiles>
将此添加到您的父pom并执行mvn clean install -DrunTestWithJacoco
而不是mvn validate -DcreateJacocoReport
。现在您可以完全覆盖一个类,并且无论哪个测试覆盖它都无关紧要。神奇的是使用maven.multiModuleProjectDirectory
创建一个组合的jacoco.exec文件。此属性从maven 3.3.1开始可用,并指向您启动maven构建的文件夹。

我认为jacoco
或cobertura
中的任何一个都无法报告跨模块的代码覆盖率。您可能希望在运行测试覆盖率报告之前尝试检测已编译的类,而不是依赖于即时检测。
请参阅此jacoco
maven goal以执行离线检测。

自Jacoco版本:0.7.7起,您可以使用report-aggregate
。

如果您使用Jenkin,则可以使用jacoco插件和<goal>report</goal>
,而无需其他新功能。
