Introduction of Web Service

What is a Web Service?

Web Service is the workplace within which a user can test the RESTful APIs by sending the request to the server.

Why do we need Web Service?

  • Web Services are the mechanism or the medium of communication through which two applications/machines will exchange data irrespective of their underlying technologies.
  • Web services help the two applications to exchange information with each other when the application is running on the same or different platform.
  • Any service that is available on the web is called a web service.
  • All Web services are APIs, but all APIs are not web services.
  • Web service helps the user to share the functionality of one application with any other application without sharing the source code and database data, even when both applications are running on the same or different platforms.

Why Web Service Testing?

  • The purpose of Web Service Testing is to verify that all of the APIs exposed by your application are working as expected w.r.t functionality, performance, and security.
  • All web services are exposed via API.
  • Testing requests and the responses of the API are called web service testing.
  • Web service providers have to test all the APIs to make sure all the functionality that is exposed via web service, is working.

Prerequisites for Web Service:

  • One Project Should be created.
  • One module should be created.
  • Inside the created module, a script should be created.

Navigate to the Web Service page:

Navigate to Web Services present in the scripts screen. There is one way to navigate to the Web Services page present in the scripts screen.

  • Home icon > Project > Test Development > Module > Script > Web Service Tab

Inside the scripts screen, provided with the “Web Service” tab.

Upon clicking on the “Web Service” tab it will turn into a dropdown with the following options:

i) Rest API

ii) Snippet

iii) History

iv) Setting

How to automate Web services requests?

  • You can automate Web Service requests by adding it as a step and can execute those steps at the step level, script level, and module level.
  • In this document, you will be explained about the “Web Service tab”.

What happens when a user tries to navigate to another tab?

  • When a user has entered some data in the web service tab and then clicks on another tab (ex: steps or variables tab), a warning popup will be displayed with the ‘Exit’ and ‘Cancel’ buttons.
  • Upon clicking on the ‘Exit’ button, a warning popup will be closed and web service data will be lost and the user will be navigated to a particular tab that he clicked on.
  • Upon clicking on the ‘Cancel’ button, a warning popup will be closed and the user will remain in the web service tab.
    Note: If the user doesn’t have any data in the web service tab and clicks on other tabs, the user will be directly navigated to the respective page that he clicked on and a warning popup will not be displayed.
