From there, I created a brand new SOAP project from a WSDL, then I went to the generated test case request. I clicked on the green + icon to add an assertion, then I had the exact same problem. The pop-up window opens, all categories on left side are displayed but when I click on any of them, nothing happens. I am stucked with the type Contains that is associated to the Recently Used category. Then googling about the error in the log, I saw this: http://stackoverflow.com/questions/31409653/classnotfoundexception-after-updating-to-soapui-5-2-0 I did what this guy did and yes, no more error in the log, but still incapable to add assertions in my project. New log attached. Re: Unable to add assertion OK, I started this morning with fresh log files (0 bytes), I just started SoapUI, tried to add a new assertion in one of my test cases, then closed. 2 log files attached. Re: Unable to add assertion I am trying to do exactly what's in the tutorial video, but the tool behavior is different for me. At 3:15 in the tutorial, the user clicked on the Add icon and the dialog is shown with all possible options. When I do the same (on my version the Add icon looks like a green + sign), the dialog opens but with only one option "Contains" available. All others are missing, even if I click on Property Content category on the left side. Actually, clicking on any category doesn't do anything for me. Thanks for your help Re: Unable to add assertion I see tons of errors in the logs that I cannot interpret. That's why I already attached them in my original post. Thank you Re: Unable to add assertion Not sure what you mean by this. I have a TestSuite containing multiple TestCases, each one having one TestStep with one SOAP request inside. The SOAP requests actually work, but when I tried to add an assertion to the TestSteps, I ran into the issue mentionned in my post. Thanks for your help. Re: Unable to add assertion I wish I could. When I click on any item on the left side, nothing happens. It doesn't behave as in the page you mention. Re: Unable to add assertion Hi jbuttimer, Here is what mean. Thanks Re: Unable to add assertion To be more accurate, I am able to add Contains assertions, but that's about it. I need to use XPath and Not Contains as well, but those options are not even proposed. Unable to add assertion Hi, with a very simple project, I am trying to add assertions to my SOAP requests. When I clicked on the + icon, the dialog opens, but all is shown is Contains. All the others types are missing. Also, I cannot select any option on the left. Working with SoapUI 5.2.1 on Win 7 64. Logs files attached. Anyone can help me on this? Thanks
