What is Web Service Testing?

A Web Service is a software that allows machine-to-machine communication over the internet. It uses web technology such as HTTP to transfer messages between applications or electronic devices. These messages are usually in XML or JSON file formats.

A web service is built on the Request-response technique. You can implement it using either SOAP or REST (Representational state transfer). Both methods support XML data transfers.

Web Service testing concept:

  • Understanding the functionality of the web service. A web service’s functionality can be described using WSDL files (web services description language).
  • Determine the XML response and request format.
  • Sending a request and validating the response.

To test web services, we have both manual and automation testing tools.

Manual testing requires that we write our own code to send a request and verify the response. Automation testing is the opposite. It saves time and reduces coding.

After having a good understanding of web service testing, this article will discuss the various web service testing tools on the market.
