Test-Driven Development

Building confidence one test at a time. Cultivating a culture where tests dictate architecture.

The Red-Green-Refactor Cycle

We firmly believe in the TDD lifecycle. Before you write a single line of feature code, you must first define its expected behavior via a test.

Red: Write a test that fails. This defines your intent.
Green: Write the minimum amount of code required to make the test pass.
Refactor: Improve the code structure, remove duplication, and optimize without changing behavior.

Platform Enforcement

Python Code Nanny integrates automated watchers into your development environment. Whenever a file is modified, the associated test suite runs instantly. This immediate feedback loop ensures that you never drift far from a passing state, making TDD an organic part of your workflow rather than an afterthought.
