You can use the following assertions to verify functioning of REST, SOAP and JMS virtual services:

Assertion	Description
Contains	Checks if the incoming request body contains specific data. Fails, if the body has no such data.
Not Contains	Checks if the incoming request body does not contain specific data. Fails, if the body contains this data.

Assertion	Description
Message Content Assertion	Lets you build a complex check that includes multiple smaller checks of XML data. Each smaller check can use its own condition and expected value.
XPath Match	Checks if the incoming request body contains a specific node (element or attribute) and if the node value equals to the expected value. To extract data from the request body, the assertion uses an XPath expression.
XQuery Match	Checks if the incoming request body contains specific data. To extract data from the request body, the assertion uses XQuery code.

Note: The following assertions use JsonPath expressions to extract data from the body of an incoming request.

Assertion	Description
JsonPath Count	Counts the number of occurrences of a specific element in the incoming request body. Fails if this number differs from the expected value.
JsonPath Existence Match	Checks if the incoming request body contains a specific element.
JsonPath Match	Extracts data from the incoming request body and compares it against an expected value.
JsonPath RegEx Match	Extracts data from the incoming request, applies regular expressions to it and compares the result with an expected value.

Assertion	Description
HTTP Header Exists	Checks whether the request contains a specific HTTP header. Fails if the request does not have this header.
HTTP Header Equals	Checks whether the request contains a specific HTTP header with a specific value. Fails if the header does not exists or has an unexpected value.
Swagger Compliance	Checks whether the request complies with a specific Swagger definition. Fails if the request does not comply with the definition.

Assertion	Description
Script	This assertion uses a Groovy script to perform arbitrary checks of incoming requests. The script should return `true` or `false` to signal whether the assertion passes or fails.
