Web Services automation steps using Web Performace Test Template in TFS 2010

In VSTS 2010 for Web services automation use the Web Performance test template and follow below steps.

1. Open the VSTS 2010 and click on Test  New Test
2. In “Add New Test” Window in Templates list select “Web Performance Test”  Enter Test name in Test name edit box (ex:-Name.WebTest)  Select one of the among the displayed test project technology ( Create a new Visual C# test Project …/ Create a New Visual basic test Project…/ Create a new Visual C++ test Project … or if any Project is existed, if we want select existing project) in “ Add to Test Project:” combo box  Click on OK
3. It prompts New Test Project Popup  enter a name for new project and click on “Create” button. Then it creates new solution with one project and then open browser with “Record”, “Pause” and ”Stop” buttons.
4. Click on “Stop” button  It creates ”Name.WebTest” file with given Web test name node
5. Right Click on Web Test name node and click on “ Add Web service Request” , then it create “http://localhost/ “ - -> “String Body” Sub nodes under Test Node name
6. Right click on “http://localhost/” node or select “http://localhost/” and press F4, it opens “Properties” pane in right hand side of the screen.
