TDD
Test-Driven Development (TDD) is a software development methodology whose core cycle consists of writing a failing unit test first, then writing the minimal implementation code to make the test pass, and finally refactoring. The method uses short iterative loops as its basic unit, emphasizes writing tests before code, and aims to improve code quality, maintainability, and design soundness. It is widely applied in agile software development practices.
Core Facts
Test-Driven Development (TDD) was proposed by Kent Beck in 1999, with a core workflow of red-green-refactor.
The core TDD cycle is: first write a failing test case (Red) → write the minimum amount of code to make the test pass (Green) → refactor the code (Refactor).

The workflow combining TDD with AI Agent is: first write test cases, have the Agent generate implementation code that passes the tests, and after the Agent executes the tests it automatically iterates and revises based on failure information until all tests pass.
TDD fails for AI agents because even when tests are written first, the agent still uses the same language model within the same context window to understand the requirements, making it impossible to separate the cognitive sources of the question-setter and the question-answerer.
Superpowers' TDD skill guides Claude to write tests first, then write the implementation.
The Superpowers plugin ensures code quality through test-driven development (TDD), with a workflow divided into three steps: proactively clarifying requirements, breaking down tasks, and writing tests before implementation.
The co-generation test trap refers to the situation where test code and the code under test are generated by the same agent in the same session and may share the same flawed premises, causing tests to pass while the logic is incorrect.
A TDD test-driven approach can be adopted, having the AI write tests first and then write the implementation to pass those tests.
Implementing incremental validation mechanisms by running lightweight checkpoints immediately after each architectural decision applies a TDD-like philosophy at the architectural level.
Uncle Bob believes agents should not be forced to follow the strict rhythm of TDD, because TDD is a discipline designed for the limitations of human short-term memory.
