Unit tests with GenAI
GenAI can save considerable time in writing unit tests. As the name suggests, each unit test is designed to test a single unit or aspect of the code. In fact, they are focused on the smallest fragments of code that can be separated and tested in isolation. Together, they provide confidence that the code functions correctly at the component level and provide an early signal of issues when the code is refactored. The same developer typically writes the code implementation and unit tests. The unit tests prove that the code functions correctly, as understood, and may also help define the requirements.
By their nature, unit tests require a deep understanding of the business and software requirements and how each method fulfills those requirements. One must consider the intended functionality as well as the variety of edge cases for each method separately and incorporate those into the test framework. This includes decisions on the test framework, method call,...
