Development testing (DevTest) is an approach in software development that aims to bring the development and testing phases closer together.
In traditional software development, development and testing are two separate siloed functions. The challenge with this approach is that it introduces delay between code being written and that same code being tested.
In DevTest, these phases are more tightly integrated so that code that is being written and checked in is automatically tested. In this way, problems can be more quickly discovered and addressed.
