How to remove Custom Properties from a SoapUI TestCase using Groovy?

Question

I have created some list of properties under the TestCase. For example look at the following screenshot.

Answer 1

Manual solution: use "Save Properties" and "Load Properties" from SoapUI

1. export the properties to a text file, e.g. customprop.txt
2. edit the file and delete the unwanted properties
3. import the file back into your soapUI project
4. in the "load properties" dialog check the option to "delete remaining"

Then the existing properties will be cleared out and replaced with your customprop.txt
