JaCoCo 提供该功能。
定义JaCoCo插件使用配置规则COVEREDRATIO的LINE和BRANCH：
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.7.201606060606</version>
<executions>
<execution>
<id>default-prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>check</id>
<goals>
<goal>check</goal>
</goals>
<configuration>
<rules>
<rule>
<element>CLASS</element>
<limits>
<limit>
<counter>LINE</counter>
<value>COVEREDRATIO</value>
<minimum>0.80</minimum>
</limit>
<limit>
<counter>BRANCH</counter>
<value>COVEREDRATIO</value>
<minimum>0.80</minimum>
</limit>
</limits>
<excludes>
<exclude>com.xyz.ClassToExclude</exclude>
</excludes>
</rule>
</rules>
</configuration>
</execution>
</executions>
</plugin>
支持的counter选项有：
我相信INSTRUCTION您可以进行一般检查（例如，验证整个项目的覆盖率至少为0.80）。
本示例要求整个指令的覆盖率为80％，并且不得错过任何课程：
<rules>
<rule implementation="org.jacoco.maven.RuleConfiguration">
<element>BUNDLE</element>
<limits>
<limit implementation="org.jacoco.report.check.Limit">
<counter>INSTRUCTION</counter>
<value>COVEREDRATIO</value>
<minimum>0.80</minimum>
</limit>
<limit implementation="org.jacoco.report.check.Limit">
<counter>CLASS</counter>
<value>MISSEDCOUNT</value>
<maximum>0</maximum>
</limit>
</limits>
</rule>
</rules>
如果覆盖范围不符合预期，它将失败并显示以下消息：
[WARNING] Rule violated for class com.sampleapp.SpringConfiguration: lines covered ratio is 0.00, but expected minimum is 0.80
[WARNING] Rule violated for class com.sampleapp.Launcher: lines covered ratio is 0.33, but expected minimum is 0.80
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
在上面的示例中，我设置了<exclude>com.xyz.ClassToExclude</exclude>。我认为您会发现需要添加许多排除项。项目通常包含许多无法测试/测试的类（Spring Configuration，Java Bean …）。您也许也可以使用正则表达式。
