The application allows you to create and configure API packages, revenue models, reports, payment gateways, and integrations with developer portals.


6. JMeter

JMeter is an open-source tool developed by Apache that analyzes and tests the performance of software applications, products, and services. Originally designed for load testing, this tool is now widely used for functional API testing. A wealth of API testing functionality and additional features to enhance the process are available. This tool can be used to unit-test JDBC database connections. JMeter version 5.4 was released in December 2020, with bug fixes and core enhancements.


7. Rest-Assured
