Windows 10 21H1 64-bit Katalon Studio 188.8.131.52
I have a serious problem with Katalon Studio, that it binds all Variables to Test Cases as String and totally ignores selected Data Types. This appears to be true whether or not the “Bind to test case as String” checkbox is selected on the data file. I found other guys here on Forum or elsewhere on the Internet that said, that they couldn’t make it work neither, so I am convinced this isn’t actually working for anybody. But it is a serious problem, because at least boolean (to parametrize checkboxes for example), numbers and lists should really be working. Maybe even custom Data Types would be of use. But sadly, everything is just a string and it is painful to manually parse everything from String.
This is very weak point of Katalon Studio, so I believe you should highly PRIORITIZE IT
