SoapUI
SoapUI is an open-source API testing tool designed for testing web services, including SOAP and REST APIs. It provides a user-friendly interface for creating, executing, and validating API tests, supporting functional, load, and security testing. The tool is widely used in software development and quality assurance to ensure API reliability and performance.
Developers should learn SoapUI when working with web services, as it simplifies API testing by automating requests, assertions, and data-driven scenarios. It is particularly useful for testing SOAP-based services in enterprise environments, REST APIs in modern applications, and for performance testing under load. Using SoapUI helps catch bugs early, validate API contracts, and ensure seamless integration between systems.
