Root Cause

A test tries to open a file that does not exist in the current working directory or specified path.

generic

中文

测试尝试打开当前工作目录或指定路径中不存在的文件。

Workarounds

  1. 95% success Use relative path with proper test directory 
    import os; filepath = os.path.join(os.path.dirname(__file__), 'test_data.csv')
  2. 90% success Create test data using pytest fixture 
    @pytest.fixture
def test_data():
    return {'key': 'value'}

Dead Ends

Common approaches that don't work:

  1. Creating an empty file with same name 70% fail

    Empty file may cause parsing errors or incorrect test results.

  2. Hardcoding absolute path 50% fail

    Absolute paths break portability across different environments.
