Start by selecting the "Add Assertion" button in the Assertion Toolbar and selecting the "XPath Match" assertion in the prompting dialog:Īfter pressing OK, the following (empty) configuration dialog is opened: Let's jump right in, here is a login response message that we want to validate īasically we want to check for the loginResponse and sessionid elements in the SOAP Body, but ignore the actual value of the sessionid since it will change between each request. If the values match the assertion passes, otherwise it fails. The XPath assertion applies a specified XPath expression to the received message and validates the resulting nodes against an expected value.
Check out their website to get details on supported standards, reference documentation, etc. Quick Tip: Both the XPath and XQuery Match assertions make use of the Saxon XPath / XQuery processor which supports most of the latest standards in this area. Let's have a look at each together with some examples! This also makes way for two of the most powerful assertions, XPath Match and XQuery Match, which both utilize the named technologies to provide fine-grained message validation possibilities. All messages received by sampler TestSteps are internally converted to an XML counterpart, which provides a common ground for assertions and other post-processing.
