REST Request

  • You can add Web Services request directly from the object details view. Simply click on the plus icon to add to New or any Existing test case.

  1. Select File > New > Web Service Request from the main menu. The New Web Service Request dialog will be displayed where you can input your RESTful URL directly on this dialog.

  2. After you've created a request successfully, there will be a small icon next to the object on Tests Explorer to indicate its used method 

  3. In the opened editor of the new service request object, there will be two separate sections for the **Request **(left pane window) and Response (right pane window)

We will take a look at the Request section using the sample REST URL${status}
