Hi!
Well, it depends on what kind of property you are referring to. I assume you mean a project property for instance.
If you want to do it manually, you could of course change the value in the Custom Properties tab in the bottom left corner. Else I belive you have to use a Groovy Script somehere, either in an event handler or in an explicit Groovy Script TestStep.
The syntax for setting a property is fairly trivial though:
testRunner.testCase.testSuite.project.setPropertyValue( "MyProp", someValue )
This code could be put into a Groovy Test Step after the property has been defined.
