Unit tests are super important for finding and fixing problems in Ruby back-end development. Here’s how they help:
Quick Feedback: When you write a test and run it, it shows you any broken code right away. For example, if you expect a method to give back a user object but it returns nothing (nil), the test tells you it’s wrong.
Stops Bugs from Coming Back: Once you fix a bug and create a test for it, that test runs every time you make changes. This way, the bug won’t pop up again later.
Confidence in Your Code: With a good set of tests, you can make changes to your code without worry. You’ll know that the tests will catch any new mistakes.
In simple terms, unit tests are like a safety net in your Ruby back-end development. They make it easier to find and fix errors!
