Hi Katalon,
For Web Testing, we can always test a specific Xpath is correct via the developer tools within the browser.
For Mobile Testing in Katalon, we can using the Mobile Object Spy in capturing the object. This is assuming that the properties/xpath are not dynamic. In the event that we required to modified the captured XPath dynamically, we will need to verfiy if the Xpath modified is identified the correct element, before we run the test case.
Is there any option within Katalon that we can verify the modified Xpath ? ie. Filter the object repository with the Xpath defined? This is a very important feature as part of the test script design stages to ensure the element are correctly identified.
