Ensuring that test modules and packages adhere to Python’s naming conventions is critical for successful execution and maintainability. A module or package name must start with a letter or underscore, and consist only of letters, numbers, and underscores. Invalid names can lead to import errors and prevent tests from being discovered by test runners. For example, a module named “1test.py” would violate this rule, whereas “test_1.py” would be valid.
Adhering to established naming conventions promotes code clarity, reduces debugging time, and facilitates collaboration within development teams. Furthermore, many testing frameworks rely on these conventions to automatically identify and execute tests. Historically, inconsistencies in naming practices have been a common source of errors in Python projects, underscoring the ongoing importance of this seemingly simple rule. Failure to comply can impact the entire testing process, leading to inaccurate or incomplete results.
