根据昨天网上百度到的东西之中，发现了一个maven插件也能够实现生成测试覆盖率maven-surefire-plugin插件。这个插件是运用于maven生命周期的测试阶段，通过maven-surefire-plugin插件来执行Junit或者TestNG的测试用例 。可以称之为测试运行器。
使用这个插件pom.xml配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>se.thinkcode</groupId>
<artifactId>one-module-example</artifactId>
<version>1.0</version>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.5</version>
<configuration>
<includes>
<include>**/*Test.java</include>
</includes>
</configuration>
</plugin>
</plugins>
</build>
</project>
include设置的是包含的测试源文件，在默认情况下会自动扫描符合以下要求的测试类
**/Test*.java
**/*Test.java
**/*TestCase.java
测试截图：

这个插件还能跳过测试
<configuration>
<skipTests>true</skipTests>
</configuration>
跳过某些用例
<configuration>
<excludes>
<exclude>**/*Test.java</exclude>
</excludes>
</configuration>
这样就把所有以Test为后缀的测试类忽略掉。
测试结果：
写的唯一一个测试类，也没有被测试到。

覆盖率结果：
因为没有被执行，所以覆盖率为0。
