Application Programming Interface (API) is a set of tools, conventions and subroutines that are used to build applications. API is a communicator between User Interface and database. API generally focusses on making requests to API endpoints and validating the response from them.

 API testing is used to validate application programming interfaces, typically performed to check reliability, functionality, performance and security of the programming interface.

While the traditional testing puts more emphasis on look and feel and functionality, API testing aims at testing business logic, validating data responses and security, performance testing, etc.

API Testing

API Testing – A game changer in service-based architecture.

API works as a middle layer in testing an application and should happen before database testing. It is important to understand how API works as opposed to other testing types. API testing is a type of testing with the help of web-services, making sure that API passes all the other types of testing such as Functional Testing, Reliability Testing, Performance Testing, Security Testing, Integration Testing, etc.

Below mentioned are the advantages of using API testing for your application-

  1. Early and fast releases- API testing saves huge time compared to UI testing due to GUI Independency.
  2. Test Coverage - Most of the tools used for API/web services testing improves test coverage with the help of automated tests for functional as well as non-functional test scenarios.
  3. GUI and language independent – API testing can be performed in the application, even before the UI testing is started traditionally. Exchange of data happens in the form of XML and JSON formats which is why any language can be used to automate an application.
  4. Better customer experience – Due to the reduced cost, faster processes and thorough testing, customer experience can be improved.

API Testing Market Worldwide –

API has extended the reach in IT and Telecommunications, financial services, banking applications, retail, insurance, ecommerce, healthcare and what not!

API Testing market segmentation globally is as follows –

  • API Testing tools and software
  • API Testing services –
  1. Managed Services
  2. Professional Services
  3. Cloud Integration and migration
  4. Training and Consulting

 

This article will help you understand different API tools along with the testing trends. At TestoMeter, aspirants enrolling to the specific course ‘API Testing’ will have a complete exposure to API testing terminologies, along with hands-on experience on the relevant tools and practices that are useful while dealing with APIs/ web services.

There are many tools available in the market for API Testing. Let us understand the most widely used –

  1. Postman – Postman is a scalable tool for testing APIs/ web services that can integrate easily into CI/CD pipeline. Creation of multiple tests, integration, automating the tests and debugging is easier.
  2. Katalon Studio- It is an automation tool for all types of testing including API testing. It supports SOAP and REST, used data driven approach and makes easier CI/CD integration.
  3. REST Assured – It is an open-source tool that supports XML and JSON requests or responses. Robust implementation makes it easier to use.

TestoMeter ensures that the candidate willing to learn gets end to end knowledge along with the practical experience necessary to implement it in the applications. TestoMeter also provides live project experience in the relevant domain.

Wrapping Up-

API Testing is the most widely testing nowadays in any industry that you name! There are a lot of tools available in the market. You just have to choose the relevant tool wisely depending on the SOAP/ REST API that has been associated with your application. If you want to stand out and being at the top position in your career, understanding API testing and switching your career in that direction will help.

In the end, we should make it a point that APIs in the future will be more intelligent with respect to the pattern of communication and hence the respective trends!
