Jacoco考试不及格覆盖范围始终为0

问题描述

Jacoco插件丢失了JUnit测试，始终报告0％，但该测试存在。我认为问题是我的pom.xml。帮我找出错误。

Pom.xml on GitHub

也许与checkstyle插件冲突？

具有Jacoco设置的零件：

解决方法

没有执行测试，因此没有覆盖范围。

---

您在build log中拥有

[INFO] Tests are skipped.

这可能是由于您的.github/workflows/build.yml中的-DskipTests

run: mvn -B clean package -DskipTests

---

执行mvn test会产生

[INFO] --- maven-surefire-plugin:2.22.2:test (default-test) @ bridge ---
[INFO]
[INFO] -------------------------------------------------------
[INFO]  T E S T S
[INFO] -------------------------------------------------------
[INFO]
[INFO] Results:
[INFO]
[INFO] Tests run: 0,Failures: 0,Errors: 0,Skipped: 0

因为您有junit-jupiter依赖项， 但没有junit-vintage-engine（请参阅mvn dependency:tree的输出）， 而您的测试是使用JUnit 4编写的。

---

在删除以下junit-vintage-engine

之后，

             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-starter-test</artifactId>
             <scope>test</scope>
+            <!--
             <exclusions>
                 <exclusion>
                     <groupId>org.junit.vintage</groupId>
                     <artifactId>junit-vintage-engine</artifactId>
                 </exclusion>
             </exclusions>
+            -->

执行mvn test会产生

[INFO] Tests run: 47,Skipped: 0
