i got this when you are using katalon studio you may face these kind of things.
when you click on Add → Web UI Keyword
by default katalon will insert the WebUI.accept alert.
there are 2 scenarios
1
in existing test case
You Don’t need to Search for where it is gone after doing ADD.
if you want a Web Ui Keyword at 4 line of a script select the 3rd line and click on add → Web UI Keyword
it will insert the keyword in 4 th line.
2
while creating new test case
by default when u click on Add → Web UI Keyword
it will insert the Accept alert at the end of the test script
i Hope this will help you.
as like the saying Practice makes them perfect you will understand and you will come up with new ideas too
