问题描述
当我运行一些 JUnit 5 测试时(在同一个项目中也有 JUnit 4 测试,因为我们正在向 JUnit 5 迁移),我看到这个错误:
No tests were executed
...
Caused by:
java.lang.classNotFoundException: org.junit.jupiter.api.extension.ReflectiveInvocationContext
如何解决?
解决方法
确保您的 pom.xml
中有这些依赖项:
- org.junit.jupiter:junit-jupiter-engine
对于 JUnit 4:
- junit:4.12+
- org.junit.vintage:junit-vintage-engine(仅支持 JUnit 4.12+)
如果你想使用@ParameterizedTest:
- org.junit.jupiter:junit-jupiter-api
- org.junit.jupiter:junit-jupiter-params
org.junit.platform:junit-platform-launcher
不是必需的,即使您想在 Intellij 中运行测试。也许你可以试试不加它。
