The Testing Pyramid is like a guide for developers and QA teams to make sure they’re building good software. It helps them decide what kinds of tests to use and how often to run them. By following the pyramid, teams can quickly check if their changes break anything and make sure their software works well.
Imagine the pyramid as a stack of different types of tests. At the bottom, there are lots of small tests called unit tests. These tests check if individual parts of the code work correctly. They’re quick to run and catch problems early.
In the middle of the pyramid, there are integration tests. These tests check if different parts of the software work together smoothly. They’re a bit bigger than unit tests but still important for catching issues before they become big problems.
At the top of the pyramid, there are end-to-end tests. These tests act like real users, checking if the whole software works as expected from start to finish. They’re slower and more complicated but can catch issues that other tests might miss.
