Introducing Web Testing Using VSTS

This article provides an overview of testing web application functionality using VSTS. It begins by providing a step-by-step approach on how to set up a Web test case and customize it without writing any code. This article demonstrates an approachability of VSTS Web Testing by all those participating in the development process, including non-developer types. Web test cases can easily be coded as well, and we will describe how to use coded Web tests or extend the built-in Web testing support.

Before we begin, readers should be aware that VSTS functionality is not targeted at testing the user interface. It doesn't run JavaScript in a webpage or validate the appearance of a page within multiple browsers. Rather, the testing approach is to examine HTTP data flowing over the wire and provide various rules for validating this data.

Process Of Web Testing

Visual StudioTeam System Test - VSTS

VSTS could be used for the following:
1) Unit testing
2) Web testing
3) Load Testing

Web test in VSTS could be used for automated functional testing. It records HTTP transactions and not API calls. The language used is C# or VB.NET
Pros of using VSTS:
1) Parameterization of test data possible
2) Add validation points( called Validation Rules)
3) Script is reliable where frequent UI changes take place

Cons of using VSTS:
1) No UI, Database validation possible.
2) No Flow control or other programming constructs provided by other auotmation languages.
3) Does require higher skill set for functional testers.

Thus Microsoft VSTS is competing with HP QTP in terms of automated testing. But I feel VSTS has a long way to go still, looking at advantages QTP provides.

How to call the Functions in other libraries

'Create file system object

Set fso=CreateObject("scripting.filesystemobject")
'Open library fileSet sFile=fso.OpenTextFile("C:\Documents and Settings\sudhakar kakunuri\Desktop\Script Control\source.vbs")
'Read the complete data from library fileSourceLibraryData=sFile.ReadAll'
close the files
File.Close
'Create Script Control Object
Set scrControl=CreateObject("msscriptcontrol.scriptcontrol")
'Specify the language to be controlled
scrControl.Language = "VBScript"
'Add the source library code
scrControl.AddCode(SourceLibraryData)
 'Diplay the number of procedures in th source library
MsgBox scrControl.Procedures.Count,,"Total Procedures Count"
'Display value of a variable in source library
Msgbox scrControl.Eval("a"),,"Value of Variable 'a'"
'Executing the function source library function
scrControl.Run "demo"
'Executing the function source library function with parameters
msgbox scrControl.Run("demo_add",10,20),,"demo_add function Result"
