Feedback

Test code that can’t be safely imported

• Both reliability issues come from test definitions that will raise at import/collection time (undefined Mixin, top-level undefined names). The Flake8 cases are syntactically valid but not runnable.
• For this style of “lint-only” tests, it’s helpful to keep them import-safe even if execution is never intended.

Signal vs. noise in test fixtures

• The hygiene issues (unused imports, empty function bodies) are all in these same test files, where the goal is to exercise a linter rule.
• When tests are intentionally “weird” to trigger diagnostics, small comments or minimal cleanup can help future readers distinguish deliberate oddities from accidental ones.

Instance method without `self` wastes memory and CPU

The method concrete_method does not utilize its self parameter, meaning it doesn't rely on instance state. Python currently creates a bound method for each instance, which consumes extra memory and CPU time unnecessarily. This inefficiency can be avoided by removing self and marking the method as a @staticmethod.

Apply the @staticmethod decorator to the method and remove the self parameter to prevent Python from creating bound method wrappers and optimize both memory and performance.

Empty function body causes confusion without explanation

The function my_function is defined but has no implementation or explanation such as a comment or docstring. This makes it unclear whether the function is intentionally left blank, incomplete, or forgotten, which can confuse developers or maintainers.

Add a comment explaining why the function is empty, include a docstring if appropriate, or raise an explicit exception such as NotImplementedError to clarify the intent and prevent silent omissions.

Empty function body causes confusion without explanation

Function another_function is defined but has no body implemented or explanation provided. This creates ambiguity around whether the function is intentionally left empty or simply incomplete, which can confuse maintainers or lead to unexpected runtime behavior.

Add a comment explaining the reason for the empty body, a descriptive docstring, or raise a NotImplementedError to communicate intent explicitly and prevent misuse.

Use of undefined `some_value` causes runtime error

The variable some_value is referenced in the condition expression but is not defined or imported in the visible code context, causing a runtime NameError. This breaks code execution and must be resolved before deployment.
Define or import some_value properly before its usage, or correct any typing mistakes in the variable name to ensure it is recognized by the interpreter.

Undefined `other_value` causes runtime error

The variable other_value is referenced without being defined or imported, causing a runtime NameError that interrupts program flow. This can occur due to typos or missing declarations.

Define or import other_value properly before use to avoid runtime failures and ensure correct program execution.

Undefined `Mixin` causes runtime NameError

The symbol Mixin appears on line 254 but lacks any definition or import, causing a NameError at runtime. This prevents the program from correctly utilizing or instantiating it and crashes execution.

Define Mixin in the current scope or import it properly from its module to resolve the undefined reference error and ensure smooth runtime behavior.

[deepsource-development]

Undefined name causes runtime error

The code snippet shows an incomplete statement or use of a name without definition, which will cause a runtime NameError or syntax failure preventing execution.

Review the statement or variable usage to ensure all names are properly defined or imported, and correct any typos or incomplete code statements.

[deepsource-development]

Undefined variable causes runtime NameError

The variable used in the assert statement at line 264 is not defined anywhere in the current scope, causing a runtime NameError when the code executes. This interrupts program flow and causes crashes. Define or import the variable properly before usage to ensure it exists at runtime.

Check for typos or missing imports and declare or import the variable before the assert statement to fix the issue.

[deepsource-development]

Undefined variable `error` causes runtime failure

The variable error is referenced without any prior assignment or import, leading to a NameError at runtime. This halts execution and prevents the program from functioning as intended.

Define or assign a value to error before using it, or ensure it is imported if it comes from another module to fix the issue.

Top-level expressions with undefined names crash test collection

This file is named as a test module, but most sample snippets are executable top-level code. During collection, import will fail on unresolved names, blocking the entire test run and masking real failures.

Move snippets into non-executed text fixtures or rename the file so pytest does not import it
