Root Cause

The fixture's finalizer (teardown) raises an exception, often because the database connection is still in use or locked when trying to close it.

generic

中文

fixture 的 finalizer（teardown）抛出异常，通常是因为在尝试关闭数据库连接时，连接仍在使用中或被锁定。

Workarounds

  1. 90% success 
    Ensure all database transactions are committed or rolled back before teardown: `yield db; db.close()`
  2. 95% success 
    Use a context manager for the database connection to guarantee proper cleanup.

Dead Ends

Common approaches that don't work:

  1. 70% fail

    This is unreliable; the lock might persist longer, and sleeping wastes time.

  2. 85% fail

    This hides potential resource leaks and can cause issues in subsequent tests.
