I found a bug within Katalon’s GUI when executing a click action in a loop.
My test case needs to click on a button a total of 10000 times. Each times a click happens, all values are saved to an Excel file (the excel file is opened, written and close on each loop).
Although I’m giving 16GB of RAM to the VM where Katalon is being executed, I get random delays after the 30th iteration.
These delays are not related to any setting in Katalon nor the algorithm itself.
They don’t seem to be related to the specific computer’s configuration whatsoever, as I tried running the same test case on two different computers getting random delays on both cases.
Delays magically disappeared once I tried running the test case from the command line, i.e. not Katalon GUI.
Generating the command line to execute the test case allowed me to execute all 10000 iterations with no random delays. Hence, there must be something related to the GUI that is causing these random freezes in Katalon’s GUI.
I wish I had more information to help you hunt this bug down. Please do let me know if there is anything else I could do to help you to locate and fix this in the next release.
