Web Services API Testing

Traditionally, test engineers have had some type of a visual user interface for testing client/server and Web applications. Web services, on the other hand, are completely without a user interface, providing only an application program interface (API). A Web service does not display a visual output for testing. Although this fact makes manual testing very difficult, Web services are ideal candidates for automated testing. As a result, some programming skills are almost certainly needed for testers
who test Web services. What about testers with less technical skills? Learn about the challenges Papa Acquah faced with Web services testing: WSDL validation, unit testing, functional testing, client side testing, and server testing. Find out how he used a test harness as well as existing commercial testing tools to accomplish his testing needs.
