Over the last few years, the demand for and usage of web services or APIs have increased very much. Web service or API is a collection of systems or software components that help an application to interact or perform some process/transaction by forming a connection between other application and server.

There are essentially 2 kinds of web service – REST and SOAP to drive the communication of data and information over internet protocol.

Since these web services are exposed to the web and distributed over various networks, they are vulnerable to risks and security threats which change the processes based on them. Therefore, testing outsourcing or APIs becomes necessary to make sure they perform rightly and respond correctly to the queries.

Web Service Testing Tools

WebInject

WebInject is a free tool for automated functional, acceptance, and regression testing of web and web services. It is a command-line tool and is based on Perl, which explains the performance of tests since it doesn’t need one to spend time at the command prompt.

Rapise

Rapise is a robust automation tool with powerful and extensible features. It is based on an open and flexible architecture for rapid functional testing of REST/SOAP web services.

Runscope

Runscope is a simple tool to test and monitor the performance of the API. It helps you check whether the web service or API returns the accurate data and also implies when things go wrong with the API.

HttpMaster

HttpMaster is another expensive tool for REST web services testing. It helps testers to test the performance of REST APIs and validate output data in formats like XML, JSON, and HTML.

TestMaker

TestMaker is an open source tool to test and monitor the performance of the web, web services and SOA application by PushtoTest.
