Root Cause

Test method took longer than specified timeout due to infinite loops, blocking calls, or slow performance.

generic

中文

测试方法执行时间超过指定的超时时间，原因可能是无限循环、阻塞调用或性能缓慢。

Workarounds

  1. 85% success Debug with stack trace on timeout 
    // Add @Timeout annotation and check thread dump on failure
@Timeout(5)
@Test
void slowTest() {
    // code
}
  2. 90% success Use assertTimeout with preemptive flag 
    assertTimeoutPreemptively(Duration.ofSeconds(5), () -> {
    // test code
});

Dead Ends

Common approaches that don't work:

  1. Increasing timeout value without investigation 70% fail

    May hide performance bugs or infinite loops.

  2. Removing @Timeout annotation 60% fail

    Test may run indefinitely in CI.
