What to Test?🤔👨🏾‍💻

When building a new app, deciding what and how to test usually comes down to priorities. I start by focusing on the important blocks of the app, like core features and anything that could break easily, such as authentication or form data. Writing tests for these areas first ensures the foundation is solid before moving forward. As for how to test, you can mix unit tests for smaller pieces of code and integration tests for how everything works together. It’s about covering the most important parts without spending too much time on every little detail early on.

Testing has some big benefits. It catches bugs early, saves time later, and gives confidence when making changes or adding new features. Without tests, you risk running into unexpected issues, especially as the app scales. Debugging becomes harder, and you might accidentally break something without realizing it. Testing helps avoid those headaches and keeps the app more stable overall.
