test-file-compaction

To reduce pytest test duplication, you can refactor test files by parametrizing identical test bodies, extracting shared setup into fixtures, and introducing shared assertion helpers. This consolidates repeated code while preserving every test case, assertion, and edge-case coverage.

Parametrizing pytest tests consolidates duplicate test bodies by collapsing multiple tests with identical logic into a single data-driven test. This refactoring extracts varying inputs into parameters, reducing line count while maintaining the exact same test semantics and execution coverage.

Yes, you can refactor test suites to extract fixtures and hoist constants without changing test order. The refactoring process explicitly preserves test IDs, execution order, and markers, ensuring debuggability and behavior remain identical while producing a runnable, refactored module.

The best way to eliminate code smells from repeated assertions in pytest is to introduce shared assertion helpers. By consolidating multi-assert checks into reusable functions, you flatten single-test classes and reduce inline repetition without dropping any validation logic.

Yes, test file compaction works with existing pytest markers and test IDs. The refactoring conforms to strict transformation rules that preserve all markers, test IDs, and execution order, ensuring the refactored module remains fully runnable and debuggable without semantic loss.
