Accelerating the Test-Driven Cycle
Self-testing code allows for testing the entire system with one command. TDD is a cost-effective way to achieve self-testing code. It’s crucial for self-testing code and TDD to have the ability to run a single command. The code should run enough to test the entire system. If your codebase is healthy, you can refactor and implement new features. A fast test suite enables an environment to refactor and try experimental designs. Quick tests increase the ability to evolve a design towards something more flexible.
Refactoring code is only sometimes necessary. Sometimes, we can take small steps before refactoring. Yet, having a fast test suite is crucial. It allows us to test many ideas for the same problem. When we want to do something different from the first step in the TDD Mantra, we must start the cycle by beginning at the system’s outer edge. This is done through an Acceptance test that describes when the user stops using the product. It’s essential to keep the Test-Driven Cycle fast and smooth, especially at the level of the rules that provide value to the business. Concepts should mean a single thing based on the context in which the concepts are used. We can identify what is required to grow an application with a process that allows quick feedback.
