Frequently Asked Questions

API Testing is a type of software testing that validates the functionality, performance, reliability, and security of Application Programming Interfaces (APIs). As part of integration testing, API Testing identifies bugs, inconsistencies, and deviations from expected behavior, thus enabling the efficiency and quality of testing to be improved. Consequently, this leads to enhanced performance of the application.

The process of API testing involves the following steps:

  • Discovery Testing: The calls listed in the API documentation are executed by the tester to validate whether it can be enumerated, updated, and deleted.
  • Usability Testing: Helps verify the functionality and user-friendliness of the API, as well as whether it integrates well with other platforms.
  • Security Testing: Helps validate the type of authentication required as well as whether the sensitive data is encrypted over HTTP.
  • Automated Testing: Performed to execute the API in timely intervals.
  • Documentation: Finally, documents and reports with sufficient details about the API and the ways to interact with it are provided by the team along with other final deliverables.
API Testing can be automated with Postman through the following steps:
  • Understand the API: The process can be initiated by exploring API in Postman and importing API specifications and Postman collection.
  • Build Test Suite: Write individual custom tests in the Postman Sandbox and parameterize requests.
  • Run Tests: Once test suites are prepared, it is verified in Postman Collection Runner and tested across environments using variables. Postman further offers Newman to run test suites and export reports using JUnit.
  • Debugging: Teams work together to analyze the reports and fix issues or roll back using in-build version control.
  • Integrate Testing with DevOps Lifecycle: This step involves exporting test suites, setting up integration with the source code repository, and adding build steps in the Continue Integration Tool to ensure the compatibility of the APIs.

A type of web automation testing technique, REST API testing is used for testing RESTful APIs for applications, as it helps record REST API’s response by sending various HTTP/S requests, which verifies whether the REST API is working as per expectations or not. This type of open-source testing is performed through various methods like GET, POST, PUT, and DELETE.

API testing can be automated with the help of various API testing tools such as:
  • Rapid API
  • REST-assured
  • Postman
  • SoapUI
  • Katalon Studio
  • JMeter
Some prominent benefits of REST API Testing include:
  • It does not require you to be an HTTP expert to write tests for API testing.
  • Does not require you to code things from scratch as it comes with some inbuilt functions.
  • Supports the syntax of Behaviour Driven Development testing, Given/When/Then, which makes tests readable.
  • Makes tests more robust.
  • Provides built-in support for object mapping.
  • JMeter
