their infrastructure work as advertised across functional, performance, and interoperability requirements. Let’s examine these Web services testing requirements for our Add Web service. • We begin by installing and running SOAPSonar. Download and Install Crosscheck Networks SOAPSonar Enterprise Edition from www.crosschecknet.com/ download/p_cust_info_try.php. • Load the WSDL published at the .NET WebMatrix Endpoint: localhost:9090/MathWS.asmx?WSDL into SOAPSonar as shown in figure 5. Figure 3: C# code generated for simple MathWS.asmx operation Add(int a, int b) Three Pillars of Web services TesTing With the WSDL loaded into the test client SOAPSonar, you are now ready to perform the three pillars of testing Web services—functional, performance, and interoperability—for your target Web service. Each of these testing criteria described below is important for comprehensive Web services-testing coverage. Functional Testing Functional testing is the first pillar of Web services testing. Functional tests for the Add(int a, int b) operation can easily be created in SOAPSonar as follows: • Configure individual test cases in SOAPSonar for the operation as shown in figure 6. Use the New Test Case button for adding test cases. Figure 6 shows six test cases in the left navigation panel. For each test case, the SOAP request value is set and saved manually by the test case author. For advanced users, the input values a and b could be retrieved from external data sources such as a RDBMS, flat files, or spreadsheets. This eliminates the need for manual entry of SOAP request fields. • Once the test cases are defined, the user can select any combination of test cases and build a test suite. To build a test suite, click Run View as shown in figure 7. From the left-most navigation panel, drag-and-drop test cases into the default test suite. In figure 7, all test cases are selected to run as the default suite. Additional test suiterun parameters can be configured from this view including protocol HTTP 1.0 or 1.1, timeout settings, and wait times between each test case. With test cases and test suites, testers can easily organize test scenarios to en- Figure 4: Interface prompt for starting application on a selected local port Figure 5: SOAPSonar with Web services WSDL loaded from .NET WebMatrix Server www.StickyMinds.com MARCH 2008 BETTER SOFTWARE 27 http://www.crosschecknet.com/download/p_cust_info_try.php http://www.crosschecknet.com/download/p_cust_info_try.php http://www.StickyMinds.com
