/**
 * Module for testing SOAP WSDL web services.
 * Send requests and check if response matches the pattern.
 *
 * This module can be used either with frameworks or PHPBrowser.
 * It tries to guess the framework is is attached to.
 * If a endpoint is a full url then it uses PHPBrowser.
 *
 * ### Using Inside Framework
 *
 * Please note, that PHP SoapServer::handle method sends additional headers.
 * This may trigger warning: "Cannot modify header information"
 * If you use PHP SoapServer with framework, try to block call to this method in testing environment.
 *
 * ## Status
 *
 * * Maintainer: **davert**
 * * Stability: **stable**
 * * Contact: codecept@davert.mail.ua
 *
 * ## Configuration
 *
 * * endpoint *required* - soap wsdl endpoint
 * * SOAPAction - replace SOAPAction HTTP header (Set to '' to SOAP 1.2)
 *
 * ## Public Properties
 *
 * * xmlRequest - last SOAP request (DOMDocument)
 * * xmlResponse - last SOAP response (DOMDocument)
 *
