SYSTEM DOCUMENTATION & REQUIREMENTS

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

Frequently Asked Questions about Python Django Testing

FAQPage Schema
How do I achieve 100% test coverage in Django with pytest?▼

Test coverage in Django reaches 100% by writing function-based tests with pytest, using Factory-Boy for deterministic test data, and running pytest with coverage enforcement flags like --cov-fail-under=100. This Skill standardizes the setup, naming conventions, and fixture patterns to make full coverage systematic and maintainable across your Django projects.

What's the best way to structure Django tests with pytest and fixtures?▼

Structure Django tests as standalone functions using in-file fixtures and explicit naming: test_<function>__<scenario>__<assertion>. This Skill provides fixture-in-file patterns that keep test setup colocated with tests, reducing conftest complexity while supporting Factory-Boy for realistic model generation and Given/When/Then patterns for complex scenarios.

How do I avoid flaky tests in Django with Factory-Boy and pytest?▼

Flaky tests in Django are prevented by using deterministic data practices: Factory-Boy generates consistent model instances, and fixed dates with time-freezing eliminate timestamp-based failures. This Skill embeds these patterns alongside pytest-django configuration to ensure reproducible, reliable test suites across CI environments.

Can I use pytest with Django settings overrides and N+1 query detection?▼

Yes. This Skill covers pytest-django usage including overridable settings for test isolation and patterns to detect N+1 query problems. Combined with coverage reporting, it ensures both test reliability and application performance benchmarking within your Django test suite.

What's the difference between function-based and class-based Django tests?▼

Function-based tests offer better readability and discovery through explicit naming conventions, while class-based tests introduce inheritance complexity. This Skill enforces function-based tests only, pairing them with in-file fixtures and Given/When/Then structure to document intent clearly and reduce test maintenance overhead.

Do I need to use Factory-Boy if I'm already using Django fixtures?▼

Factory-Boy generates realistic, related model instances more flexibly than static fixtures, making test data deterministic and maintainable at scale. This Skill recommends Factory-Boy for test scenarios requiring dynamic model relationships and consistent data across test runs, replacing fixture files in most cases.
