ok, I changed the case, but I am still receiving the assertion error:
XPathContains assertion failed for path [declare namespace ns4='http://.../common/service/response/type/v0x00'; declare namespace ns2='http://.../message/v0y00'; //ns2:retrieveMyDataResponse[1]/ns2:response[1]/ns4:exceptionMessage[1]/text()] : Exception:Missing content for xpath [declare namespace ns4='http://.../common/service/response/type/v0x00'; declare namespace ns2='http://.../message/v0y00'; //ns2:retrieveMyResponse[1]/ns2:response[1]/ns4:exceptionMessage[1]/text()] in Response
Note: the assertion error only occurs when I run using the Excel Datasource. If I perform a manual request the xpath assertion works (w/ the text()).
Thanks in advance.
