Valid response assertions-We can go to Add assertions ->compliance status and standards and choose valid http response-and we type 200 as we know valid http response is only 200.So if our request does not get a 200 response from server that means our request has failed and so valid http assertion will also fail as we put 200 as valid assertion but instead got something like 500 etc.

InValid response assertions -We can go to Add assertions ->compliance status and standards and choose InValid Http response-and we type anything that we think is an invalid status code like 404,500 etc .

Schema compliance assertions -We can go to Add assertions ->compliance status and standards and choose schema compliance-And in that we paste the WSDL file of our choice and this assertion will check if the given WSDL files follows all the standards of SOAP Protocol.
