根因分析

Mockito 默认无法模拟或间谍化最终类（需要 mockito-inline 或 Mockito 5+）。

English

Mockito cannot mock or spy on final classes by default (requires mockito-inline or Mockito 5+).

generic

解决方案

  1. 90% 成功率 Use Mockito 5+ which supports mocking final classes by default 
    // Upgrade to Mockito 5.x in build.gradle
// testImplementation 'org.mockito:mockito-core:5.0.0'
  2. 85% 成功率 Add mockito-inline dependency 
    // Add to build.gradle
// testImplementation 'org.mockito:mockito-inline:5.2.0'

无效尝试

常见但无效的做法:

  1. Removing final keyword from production code 50% 失败

    Changes production code design; may not be allowed.

  2. Using PowerMockito 40% 失败

    Adds heavy dependency and may cause compatibility issues.
