Sometimes I have the same problem, mostly with “big” test cases (daten driven etc.).
In my cases what works is:
- deleting the logs
- restart Katalon Recorder and Chrome
Which logs? Clearing the log window in the tool? I am typically running 10 test cases that do a walk the site for 1 user and clear logs in between. Most executions for me are slow even when I relaunch Chrome and Katalon Recorder.
Have you try adjust the speed slider to the fastest setting?
Yes I always make sure that the slider is set to fast. Is there anyway to see what speed is getting picked up?
One thing I noticed is that execution seems to go much faster when both browser window and Katalon recorder window are both visible on screen. When Katalon window is covered up, execution seems slower.
