Root Cause

The test file contains Python syntax errors (e.g., missing colon, unmatched parentheses) that prevent it from being parsed.

中文

测试文件包含 Python 语法错误（例如缺少冒号、括号不匹配），导致无法解析。

Workarounds

  1. 90% success Check the test file for syntax errors using Python's compile function or a linter. 
    Run 'python -m py_compile test_file.py' to identify syntax errors.
  2. 80% success Use a code formatter like black to automatically fix syntax issues. 
    black test_file.py

Dead Ends

Common approaches that don't work:

  1. Running only specific tests without fixing syntax errors in the file 90% fail

    TestLoader imports the entire module; syntax errors prevent any test from running.

  2. Adding try-except blocks around test code to handle syntax errors 95% fail

    Syntax errors occur at compile time, not runtime; try-except cannot catch them.
