jacoco - jacoco-maven-plugin 不排除测试类

问题描述

该项目的 Jacoco 报告包含测试类的行覆盖率，尽管尝试如下排除测试

        <plugin>

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

上面的 pom 基本上是我们用现有 StackOverflow 问题的解决方案对配置进行射击，但它们都不起作用。

任何反馈将不胜感激！

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为什么它们会显示在报告中，因为jacoco-maven-plugin默认情况下不会在报告中显示测试类 - 这是证明：

对于以下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：

试图盲目猜测，可以假设您的项目具有非标准结构，其中上述Example.java和ExampleTest.java驻留在同一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mvn clean verify确实执行将产生以下报告，其中包含ExampleTest.java

但是在这种情况下，以下排除**/*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>
