根因分析

通过 @ExtendWith 使用自定义 JUnit 扩展，但未正确注册或类未找到。

English

Custom JUnit extension is used via @ExtendWith but not properly registered or class not found.

generic

解决方案

  1. 90% 成功率 Register extension with @RegisterExtension 
    @RegisterExtension
static MyExtension extension = new MyExtension();
  2. 85% 成功率 Ensure extension class is public and has no-arg constructor 
    public class MyExtension implements BeforeEachCallback {
    public MyExtension() { }
}

无效尝试

常见但无效的做法:

  1. Removing @ExtendWith annotation 60% 失败

    Extension functionality is lost; tests may fail.

  2. Adding extension as a dependency in build file 40% 失败

    Extension is already available; registration issue is different.
