Figure 8-7: Exercising a model with static tests. A state model can clarify understanding of how the application works and what the different test permutations might be. Figure 8-8 contains a state model for this application. The four boxes represent the four possible states of the application, and the lines represent the actions that can be taken from each state. The states are as follows: 1. Both text boxes are clear (S1). 2. The first text box contains "Hello" and the second text box is clear (S2). 3. The first text box is clear and the second text box contains "World" (S3). 4. The first text box contains "Hello", and the second contains "World" (S4). vb.net pdf reader: A simple PDF viewer windows form - Stack Overflow vb.net pdf reader PDF Viewer SDK Control x64 - Visual Studio Marketplace

The connecting lines represent actions that cause transitions from state to state. For example, from the start state (both text boxes clear), there are three possible actions. Clicking the clear button returns the application to the same state (or does nothing depending on your point of view). Clicking either "Say Hello" or "Say World" changes the application to a new state. A random walk through the transitions and expected states might look like what is shown in Table 8-2.

The SoapRpcMethod Attribute The RPC format is expressed by the SoapRpcMethod attribute and specifies that all parameters are encapsulated within a single XML element named after the Web service method, as shown in the following code. The RPC style does not support the Literal binding mode; only the SOAP-encoded binding mode (Encoded) is accepted. POST /salesreport/SalesReportService.asmx HTTP/1.1 Host: expo-star Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "xmlnet/cs/0735618011/GetSalesReportBarChart" < xml version="1.0" encoding="utf-8" > <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="xmlnet/cs/0735618011" xmlns:types="xmlnet/cs/0735618011/encodedTypes" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <tns:GetSalesReportBarChart> <theYear xsi:type="xsd:int">int</theYear> </tns:GetSalesReportBarChart> </soap:Body> </soap:Envelope> You must include the System.Web.Services.Protocols and System.Web.Services.Description namespaces in the Web service source to use SOAP formatting attributes. Note Web service methods in which the OneWay property of either the SoapRpcMethod attribute or the SoapDocumentMethod attribute is set to true do not have access to ASP.NET objects packed in the HttpContext object. References to these objects are still allowed, but null is always returned. [stRegState.dwEAX] /* The Sales Report Web Service To see a concrete example of a Web service, let's transform the remote service created in 12 into a Web service. The Web service class makes externally available a group of functions nearly identical to that of the .NET Remoting component. In doing so, it also uses the same internal class, thus demonstrating a true reuse of code. /* Set the return value for */\ /* */\ __asm \ } /*///////////////////////////////////////////////////////////////// ///// // A convenient macro to fill out the event information structure /////////////////////////////////////////////////////////////////// ///*/ #define FILL_EVENTINFO(eFn) stEvtInfo.eFunc stEvtInfo.ePrePost = eFn ; = ePostCall ; \ \ \ MOV [stEvtInfo.dwRetValue] , EAX the information. 1 2 3 4 5 6 7 8 9 10 stEvtInfo.dwThreadId = GetCurrentThreadId ( ) /*///////////////////////////////////////////////////////////////// ///// // The version 2 macros to make life MUCH, MUCH simpler to define // hook functions /////////////////////////////////////////////////////////////////// ///*/ // Declare this at the beginning of any hook function. // eFunc - The function enumeration value. // SynchClassType - The DDOPT_* flag value for the function class you // are processing. 563 The SalesReportService.asmx file is located in the same virtual folder as the remote object. The following code shows the implementation of the Sales Report Web service. The main class is named SalesReportWebService. <%@ WebService Language="C#" Class="SalesReportWebService" %> <%@ Assembly Name="SalesDataProvider" %> using System; using System.Web.Services; using System.Data; using System.Data.SqlClient; using XmlNet.CS; [WebService( Namespace="xmlnet/cs/0735618011", Name="Northwind Sales Report Web Service", Description="The Northwind Sales Report Web Service")] public class SalesReportWebService { [WebMethod(CacheDuration=60)] public DataSet GetSalesReport(int theYear) { SalesDataProvider m_dataManager; m_dataManager = new SalesDataProvider(); DataSet ds = new DataSet(); ds.Tables.Add(m_dataManager.GetSalesReport(theYear)); return ds; } [WebMethod(CacheDuration=120)] public string GetSalesReportBarChart(int theYear) { SalesDataProvider m_dataManager; m_dataManager = new SalesDataProvider(); return m_dataManager.GetSalesReportBarChart(theYear); } } The class features two methods GetSalesReportBarChart and GetSalesReport that are simply wrappers around the same methods of the SalesDataProvider class. As we saw in 12, the SalesDataProvider class provides the implementation of business logic, including the code necessary to draw graphics. 465 Building a model can be a little challenging at first but with practice becomes an almost unconscious act for most testers. As I explore applications or specifications and draw models, I find myself thinking of the following same three questions repeatedly as I generate the model: Where am i I need to know what state the application is in now, and I need to be able to describe (or know how to verify) the current state. What actions can i do From my current state, what are the different things I can do What happens when i do them If I take an action, what state does it bring me to As my model grows, I find it useful to continue to think of scenarios and expectations as I work. Because the model lets me see early how all of the states interact, I frequently find bugs before I ever actually run any of the tests. // bRecordPreCall - Record the entry into this function. #define \ \ if \ { \ FILL_EVENTINFO \ if \ { \ stEvtInfo.ePrePost \ ProcessEvent \ } \ } \ REAL_FUNC_PRE_CALL ( ) ; /*///////////////////////////////////////////////////////////////// ///// // The ending macro for a hook function. // iNuMParams function.

For the most part, this similarity depends on the use of an intermediate, common class. Just this fact proves the extreme flexibility of the .NET Framework. Rolling your own functionalities into an interface-less Web site is just one side of a coin that has on its other side .NET Remoting accessibility. Later in this chapter, after we finish our implementation of a Web service, we'll complete the comparison between .NET Remoting and Web services. Figure 13-3 shows the typical user interface that IIS and ASP.NET provide for Web services, mostly for testing purposes. The automation approach for state-based models is slightly different from traditional approaches. Rather than automate an end-to-end scenario, test automation for models focuses on automating the } \ HOOKFN_EPILOG ( iNumParams ) ; /*///////////////////////////////////////////////////////////////// ///// // The calling convention declaration for all DD_* definitions. /////////////////////////////////////////////////////////////////// ///*/ #define NAKEDDEF __declspec(naked) /*///////////////////////////////////////////////////////////////// ///// // BIG NOTE BIG NOTE BIG NOTE BIG NOTE // The following prototypes look like cdecl functions.

If you test the Web service using a Netscape browser, you might get a slightly different user interface, depending on the version of the browser and the level of support it provides for cascading style sheets (CSS). Also bear in mind that the Web service console shown in Figure 13-3 assumes that your client machine has a program registered to handle XML files. The response of the method is saved to a local XML file that is then displayed through the registered program. On many Microsoft Windows machines, the default handler of XML files is Internet Explorer. Figure 13-4 shows what happens when you test the GetSalesReport method with the default (and test-only) user interface. transitions and verifying the states The application modeled in Figure 8-8 contains four possible states and three possible actions: "Say Hello," "Say World," and "Clear Text" Each of the actions is valid in all four states To create model-based automation for this application, I would implement just a few functions, one each for the three buttons (the actions), and four others to verify each of the states At this point, I can execute any of the available actions and have oracles in place to ensure that the application is in the expected state Tools and frameworks for MBT (discussed later in this chapter) take this testing to a new level by running through transitions and states using a myriad of different paths Graph Theory and MBT In 1737, Leonhard Euler solved the problem of the Seven Bridges of K nigsberg.
