FAQ’s

What is RestAssured in API Testing?

RestAssured is a powerful open-source Java library used for testing RESTful APIs. It simplifies API automation by providing a fluent and user-friendly syntax to validate API requests and responses effectively.

How Do You Test an API with RestAssured?

API testing with RestAssured involves sending HTTP requests (GET, POST, PUT, DELETE), validating responses using assertions, handling authentication, and integrating with Java-based frameworks like TestNG or JUnit for structured execution.

What is the Difference Between REST API and RestAssured?

A REST API is an architectural style used to design web services, allowing applications to communicate over HTTP. RestAssured, on the other hand, is a Java-based automation tool used to test REST APIs by validating responses, status codes, and data integrity.

Why is RestAssured Better Than Postman?

RestAssured is preferred for automation and integration into CI/CD pipelines, supporting parameterized tests, reusable frameworks, and BDD integration (Cucumber), whereas Postman is mainly a manual API testing tool with limited automation capabilities.

How to Automate REST API Testing?

To automate API testing, use RestAssured with Java and Cucumber for structured test cases, integrate with TestNG or JUnit for assertions, configure authentication, and implement it into CI/CD pipelines using Jenkins or Bitbucket.

What is the Difference Between TestNG and RestAssured?

TestNG is a testing framework for Java used for executing and managing test cases, while RestAssured is an API automation tool. RestAssured can be integrated with TestNG to enhance test execution, reporting, and parallel testing.

“

“We selected Testrig as our QA partner over 16 months ago and they have been a key addition to our product team. Parimal and his team members have consistently provided the level of service and interaction what we have been searching for. They have worked seamlessly with both our development group and with product management. They are a valued addition and I would definitely recommend Testrig to any company looking for highly reliable and professional QA services.”

Wayne McHugh(COO)Ganart Technologies Inc

“I’ve been working with Testrig for the past three years to help our programmers speed up and improve our development process. Testrig has been consistently thorough and professional in their work, and has helped us find innumerable and important bugs. They have also been very helpful in taking a broader understanding of our business and offering helpful usability suggestions to improve our sites. Their great work has enabled our developers to focus more thoroughly on high quality product development. I would definitely recommend them to other businesses and development teams.”

“Parimal and his team have been instrumental in helping us test and build the beta version and early release of Avorra. A concern and problem we’ve experienced in the past with offshore contractors is lack of communication and professionalism – it starts out well and dwindles over time. Parimal is extremely professional, is excellent at communicating regularly and goes way above and beyond for us…and we’re certainly not his biggest client. Stuff like building out an automated proof of concept in Selenium free of charge (on their dime) to demonstrate how we could be testing better on our project blew me away. And not charging for every minute of time he works on our project fielding questions and small tasks are added Brownie Points. Parimal really cares about the project winning and puts in discretionary effort, and THAT’S the kind of players we want on our team.”

Cameron Clancy(CEO)Avorra

“TESTRIG is doing an amazing job for over a year now in handling our Quality Assurance needs. They have worked closely with our development team and consistently tested our product by providing both Manual and Automation Testing with Selenium. I would definitely recommend TESTRIG to anyone in need of QA services.”

“We have partnered with Testrig Technologies for Cloud testing and appreciate the work done by the team. They helped us in setting up complete QA process and delivered quality work.”

“At Operance, we are so pleased to have TestRig as our QA testing partner. From the first engagement, they demonstrated professionalism and that they understood our requirements. Our TestRig QA Tester quickly settled in as a member of our team and took ownership of our QA requirements leaving our development team to focus on what they do best. The product stakeholders have commented how happy they are now that many bugs are being found proactively and usually before any users have had chance to find them which continuously improves the lives of our users.”

“Testrig were able to understand our requirement straight away. Their team worked to create a system that can be extended easily and which we use to run nightly tests to identify regression. They communicated progress daily and held regular sessions to demonstrate updates as it moved towards completion. The project was delivered on both time and budget and I have no hesitation recommending Testrig as a testing partner.”
