The Test Query Match request selector is implemented by the com.arbortext.e3.TestQueryMatch class. It evaluates an HTTP request and returns true if the request includes an HTTP query parameter with a specific value. It accepts two parameters, query-name, which specifies the name of the query parameter to test, and query-pattern, which specifies a pattern that the HTTP query parameter value must match. Any standard Java pattern, including regular expressions, can be used for the query-pattern parameter value. For compatibility with earlier releases of Arbortext Publishing Engine, if the Arbortext PE Request Manager finds that the value of a query-pattern parameter is not a valid Java regular expression and contains “*” or “?” characters, Arbortext PE Request Manager will treat the pattern as a regular expression, converting “*” to “.*” and “?” to “.”.
