OVERVIEW

In today fast-paced and ever-evolving digital landscape, payment services companies need to ensure that their systems are reliable, secure, and compliant. Testing is an essential part of this process, but with the increasing complexity of API environments, manual testing can be time- consuming and error-prone. Test automation provides a more efficient way to test APIs, ensuring that they are functioning as expected and meeting the necessary requirements.

This case study describes the implementation of a test automation framework for a payment services company’s RESTful/SOAP APIs. The company required a solution that was scalable, cost-effective, and utilized open-source tools. With the increasing complexity of its API environment, the company needed an efficient way to test its APIs. Test automation ensured that these challenges are addressed and allowed the company to streamline their testing processes, reduce the risk of errors, and improve the overall quality of its APIs with faster time to production.

CLIENT CHALLENGES

The client faced several challenges in testing its RESTful/SOAP APIs. The primary challenge was the need to reduce manual testing and bring in a scalable test automation solution.

Another challenge was to keep the costs low while ensuring the framework meets the company’s requirements. Therefore, the client was looking for a solution that utilized open-source tools, which would minimize licensing and maintenance costs.

The company was continuously adding new APIs to their environment, and the framework needed to accommodate these changes without requiring a complete overhaul of the testing process. This meant that the framework needed to be modular and flexible enough to handle different types of APIs and test scenarios.

Addressing these challenges required a careful approach that took into account the specific needs of the client. Our test automation team worked closely with the client to design a framework that was scalable, cost-effective and utilized open-source tools.

BITWISE SOLUTION

Our SDETs performed a comprehensive analysis of all the RESTful/SOAP APIs under consideration to ensure that they meet the functional and non-functional requirements of the system. This analysis included a review of the API documentation, testing of the API end points, and an assessment of the APIs performance, scalability, and security.

To create tests for these APIs, we evaluated several open-source tools and helped in automating the testing process. These tools were used to write test scripts that could be executed as part of a continuous integration (CI) process to validate the APIs for proper responses.

Our ingenious team performed a successful POC (proof of concept) by integrating these API test scripts into a CI process and validating their responses using automated tests. This POC demonstrated that the APIs were functioning as expected and could be effectively tested using automation.

Our expert team developed an API Test framework using node.js, Jasmine, and Mocha to meet the testing requirements of RESTful APIs. The framework has been designed to be reusable, and scalable. This design allows the framework to be easily extended, maintained, and updated as the APIs evolve over time.

In terms of test reporting, the API Test framework has been integrated with mochawesome reporting library to generate comprehensive reports that provide insights into the test results. These reports provide detailed information about each test case, including the test status, duration, and any errors or failures that occurred during the test run enabling the business stakeholders to take the right decisions. Additionally, the framework has been integrated with test management tools leading to faster finalization of test results.

KEY RESULTS

Bitwise developed a custom and scalable open-source test automation framework that met the client’s requirements, resulting in a 60% reduction in manual testing efforts and a positive return on investment for the client.
