How to invoke method for web services

From the previous post, this is to show you how easy you can invoke method from web services. The code below is very short just 3 lines. There are only few steps, 1st create object using Object class, then call the Activator class for creating instance of service.

//Invoke Method
Object obj = Activator.CreateInstance(service);
Object response = t.Invoke(obj, param1);

return response;

Please try to code this and if you have any questions please comment here and I would be very happy to answer your questions.

Dynamic Invocation in Wsdl Reader Class

This is one of important code in the AutoWS program, DynamicInvocation. I use this one than hybernating. You can see sample of the class and function below.

WsdlReader class:
DynamicInvocation

StringWriter stringWriter = new StringWriter(System.Globalization.CultureInfo.CurrentCulture);
Microsoft.CSharp.CSharpCodeProvider prov = new Microsoft.CSharp.CSharpCodeProvider();
prov.GenerateCodeFromNamespace(nameSpace, stringWriter, new CodeGeneratorOptions());

// Compile the assembly with the appropriate references
string[] assemblyReferences = new string[2] { "System.Web.Services.dll", "System.Xml.dll" };
CompilerParameters param = new CompilerParameters(assemblyReferences);
param.GenerateExecutable = false;
param.GenerateInMemory = true;
param.TreatWarningsAsErrors = false;
param.WarningLevel = 4;

CompilerResults results = new CompilerResults(new TempFileCollection());
results = prov.CompileAssemblyFromDom(param, codeCompileUnit);
Assembly assembly = results.CompiledAssembly;
service = assembly.GetType(sdName);

methodInfo = service.GetMethods();

next chapter I will write sample how to use this class in the AutoWS program.

Connect to Web Services, Read WSDL for Service Method and Perform a Simple Testing

Connect to Web Services, Read WSDL for Service Method and Perform a Simple Testing:

Please follow step below:

1. Please start the AutoWS program.

2. at WSDL address. Please input WSDL address for example

http://www.aswinanand.com/sendsms.php?wsdl

3. Click button [Get WSDL] then the AutoWS will connect to the WSDL address and list out Web Services Method to the left windows.

4. You can select each Web Services Methods by click at them and then Parameters of each Web Service methods will be shown in the Parameters windows below.

5. You can select method to test by clicking at [Select Method] button.

This sample we will select sendSMSToMany method.

6. Click at button [Create Test Data] for creating test case. You also can input number of run e.g. 1,2, or you require. but for DBTest please leave it 0 first. We will use this option for Database testing which we will discuss later.

7. input value of each parameters on the right window.

8. Then you are ready for a simple Test click [Run Test] button in the middle to start your Test Cases.

9. The response will show on the response column and the Test and Evaluation Report will show on the window below.

SOAP (Simple Object Access Protocal)

SOAP is a protocal for Web services that has a XML Structure according to the W3C standard.

Web Services Software Testing Blog Introduction

I wrote this topic for sharing the software testing tools that I developed for my master degree project. I study in major Computer Science , NIDA institue, Thailand. I plan to share my study and the software program tools as well.

The web services software testing software developed with C# and I plan to share you all the source code and design.
