+
+No one writes code, commits it and pushes it to production without checking it works.
+
+Everyone tests their code, but they usually do it manually. They switch from the code to a browser or terminal, run the code and evaluate the result.
+
+This takes time, you need to switch contexts, and the test is only valid for that time.
+
+There's no guarantee it will still work in the future.
+
+Automated testing, however, means you can write your code and run the tests without leaving your IDE or text editor.
+
+The tests can also be run in the future to ensure the functionality works without needing to re-test it manually.
