SoapUI

SoapUI is a testing platform that checks how APIs and web services perform. You can use it to send requests to your API, check the responses, and make sure everything works as expected. It runs on Windows, Mac, and Linux computers because it is built using Java.

The tool lets you do functional testing to verify your API works correctly, load testing to see how it handles many users, and security testing to find weak points. You can also write custom test scripts using Groovy programming language for more complex scenarios.

SoapUI works well with popular tools like Jenkins for continuous testing in your development process. The open-source version is completely free, while ReadyAPI offers extra productivity features.

Using SoapUI is straightforward once you understand the basic steps:

• Download and install SoapUI from the official website. Choose the version for your operating system and run the installer.

• Create a new project by importing your API definition. You can use WSDL files for SOAP services or OpenAPI specifications for REST APIs.

• Add test cases to check different parts of your API. Right-click on your service and select "Generate TestSuite" to automatically create basic tests.

• Set up assertions to verify that responses match what you expect. You can check status codes, response time, or specific data values in the response.

• Run your tests and review the results. SoapUI shows you which tests passed or failed with detailed information.

• For advanced needs, use Groovy scripts to handle complex testing situations like connecting to databases or manipulating data between requests.

• Connect SoapUI to your CI/CD pipeline so tests run automatically whenever you make code changes.
