I tried looking through all the pages about unit tests and could not find this question. If this is a duplicate, please let me know and I will delete it.
I was recently tasked to help implement unit testing at my company. I realized that I could unit test all the Oracle PL/SQL code, Java code, HTML, JavaScript, XML, XSLT, and more.
Is there such a thing as too much unit testing? Should I write unit tests for everything above or is that overkill?
This depends on the project and its tolerance for failure. There is no single answer. If you can risk a bug, then don’t test everything.
When you have tons of tests, it is also likely you will have bugs in your tests. Adding to your headaches.
test what needs testing, leave what does not which often leaves the fairly simple stuff.
