Python Django Testing

What problem does it solve?

This Skill enforces robust Django testing practices by standardizing function-based tests, providing deterministic data patterns, and embedding best practices (pytest, Factory-Boy, Given/When/Then) to achieve reliable, fully covered test suites.

Core Features & Use Cases

• 100% test coverage mandate for all new code, with clear guidance on enforcing coverage in CI.
• Function-based tests only with explicit naming conventions to improve readability and discovery.
• Fixture-in-file patterns to keep test setup colocated with tests, reducing conftest complexity.
• Factory-Boy for test data to generate realistic, related model instances consistently.
• Given/When/Then structure for complex scenarios to document intent and outcomes.
• Deterministic data practices using fixed dates and time-freezing to avoid flaky tests.
• Django-specific patterns including pytest-django usage, overridable settings, and N+1 query patterns.

Quick Start

Create and run pytest-based tests for your Django app, using test_<function><scenario><assertion> naming, in-file fixtures, and 100% coverage enforcement:

• Write tests as standalone functions (no test classes).
• Use Factory-Boy to generate models, e.g., UserFactory().
• Run with coverage: pytest --cov=yourapp --cov-fail-under=100 --cov-report=term-missing
