Root Cause

A test takes longer than the specified timeout, often due to infinite loops, slow I/O, or blocking calls.

generic

中文

测试花费的时间超过指定的超时时间，通常是由于无限循环、慢速 I/O 或阻塞调用。

Workarounds

  1. 85% success Add debugging output to identify where the test hangs. 
    Insert print statements or use logging to trace execution.
  2. 90% success Use pytest-timeout plugin to set a timeout and catch hanging tests. 
    pytest --timeout=60 test_file.py

Dead Ends

Common approaches that don't work:

  1. Increasing the timeout value without investigating the cause 70% fail

    The underlying issue (e.g., infinite loop) will cause the test to hang indefinitely.

  2. Removing the timeout decorator to avoid failure 80% fail

    The test may still hang indefinitely, blocking the test suite.
