jacoco-maven-plugin 不排除测试类

Question

此项目的 Jacoco 报告包含测试类的行覆盖率，尽管试图排除如下测试

        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>

                </execution>
            </executions>
        </plugin>

上面的 pom 基本上是我们使用现有 Whosebug 问题的解决方案对配置进行射击，但其中 none 有效。

如有任何反馈，我们将不胜感激！

在没有 Minimal Complete Reproducible Example 的情况下，只能猜测您的测试文件是如何放置在您的项目中以及它们为什么显示在报告中，因为 jacoco-maven-plugin 不显示测试类默认情况下在报告中 - 这是证明：

以下pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>org.example</groupId>
  <artifactId>example</artifactId>
  <version>1.0-SNAPSHOT</version>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

  <build>
    <plugins>
      <plugin>
        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
        <version>0.8.3</version>
        <executions>
          <execution>
            <goals>
              <goal>prepare-agent</goal>
              <goal>report</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

</project>

src/main/java/Example.java

class Example {
    void sayHello() {
        System.out.println("Hello, World!");
    }
}

和src/test/java/ExampleTest.java

import org.junit.Test;

public class ExampleTest {
    @Test
    public void test() {
        new Example().sayHello();
    }
}

执行

mvn clean verify

生成以下报告，如您所见，不包含 src/test/java/ExampleTest.java:

尝试盲目猜测，可以假设您的项目具有非标准结构，其中上述 Example.java 和 ExampleTest.java 位于相同的 src 目录中，并且您有以下 pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>org.example</groupId>
  <artifactId>example</artifactId>
  <version>1.0-SNAPSHOT</version>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
    </dependency>
  </dependencies>

  <build>
    <sourceDirectory>${project.basedir}/src</sourceDirectory>
    <testSourceDirectory>${project.basedir}/src</testSourceDirectory>

    <plugins>
      <plugin>
        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
        <version>0.8.3</version>
        <executions>
          <execution>
            <goals>
              <goal>prepare-agent</goal>
              <goal>report</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

</project>

然后执行 mvn clean verify 确实会生成以下包含 ExampleTest.java

的报告

然而在这种情况下排除 **/*Test.*

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>org.example</groupId>
  <artifactId>example</artifactId>
  <version>1.0-SNAPSHOT</version>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
    </dependency>
  </dependencies>

  <build>
    <sourceDirectory>${project.basedir}/src</sourceDirectory>
    <testSourceDirectory>${project.basedir}/src</testSourceDirectory>

    <plugins>
      <plugin>
        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
        <version>0.8.3</version>
        <executions>
          <execution>
            <goals>
              <goal>prepare-agent</goal>
              <goal>report</goal>
            </goals>
            <configuration>
              <excludes>
                <exclude>**/*Test.*</exclude>
              </excludes>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

</project>
