Automated Test using Katalon
I finally found a testing app outside of a framework and decided to use this because I needed the test to check for errors, it's slower than using a framework but it gets the job done. I have issues using PHPUnit for CodeIgniter, it's maybe because I have less knowledge of the matter and the project does not support it (no migration), I just need to check the errors for all the pages, not making the whole test suite, so I'm using Katalon.
There's a feature record web, so every step is added to the steps which is nice, and the copy and paste feature is good, can just copy and paste every step.
So it's safe to say that I'm using the right tool for the job.
