首页 > 解决方案 > JUnit 5 迁移 - 如何解决 java.lang.ClassNotFoundException: org.junit.jupiter.api.extension.ReflectiveInvocationContext

问题描述

当我运行一些 JUnit 5 测试时(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?

解决方案


确保您的pom.xml:

  • org.junit.jupiter:junit-jupiter-engine

对于 JUnit 4:

  • 六月:4.12+
  • org.junit.vintage:junit-vintage-engine(这只支持 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不需要,即使您想在 Intellij 中运行测试。也许你可以试试不带它。
