根因分析

使用 when() 定义的桩代码在测试执行过程中从未被使用。

English

Stubs defined with when() but never used during the test execution.

generic

解决方案

  1. 85% 成功率 Use lenient() for specific stubs 
    lenient().when(mock.method()).thenReturn(value);
  2. 90% 成功率 Remove unused stubs 
    // Remove the stub line that is never used
// when(mock.method()).thenReturn(value);

无效尝试

常见但无效的做法:

  1. Removing all stubs blindly 50% 失败

    May cause test to fail if stubs were actually needed but not triggered.

  2. Adding @MockitoSettings(strictness = Strictness.LENIENT) globally 40% 失败

    Hides real issues, may lead to false positives.
