根因分析
测试尝试打开当前工作目录或指定路径中不存在的文件。
English
A test tries to open a file that does not exist in the current working directory or specified path.
解决方案
-
95% 成功率 Use relative path with proper test directory
import os; filepath = os.path.join(os.path.dirname(__file__), 'test_data.csv')
-
90% 成功率 Create test data using pytest fixture
@pytest.fixture def test_data(): return {'key': 'value'}
无效尝试
常见但无效的做法:
-
Creating an empty file with same name
70% 失败
Empty file may cause parsing errors or incorrect test results.
-
Hardcoding absolute path
50% 失败
Absolute paths break portability across different environments.
