Experience effective testing with flexible licensing alongside pivotal insights on essential improvements
For non-functional testing, I focus on performance and security. For performance and security tests, I used REST API, SoapUI, and JMeter. These tools help us conduct thorough testing across these dimensions. I find ReadyAPI helpful especially in overcoming security issues, as we experienced slowness in the application after merging our JAR files. For instance, if a person wants to access a university database and encounters a timeout error, we learned through ReadyAPI that the issue was due to HTML protocol limits with the payload. We fine-tuned this process to display the expected data effectively. I consider ReadyAPI a cost-effective solution because it covers three verticals without needing to purchase separate tools for security, performance, or functional testing. ReadyAPI is a versatile tool for creating multiple testing frameworks and validating various parameters seamlessly. REST API is the tool I use to test all three types of articles, meaning I validate the APIs I send to my peers or clients for functional testing, and I also perform security testing to ensure the URL and data passed through multiple components adhere to policies and user privileges. This is done through functional security testing using the REST API tool, and for performance, I ensure that applications can be accessed simultaneously by multiple users without hindrance or slowness through thorough performance testing.

We can write our codes just after the functional docs are prepared, and we can straight away start testing the application in the system testing phase itself.
* Using this tool, we can automate test cases even before the deployment of an application. This can be done by scanning objects from UI mock-ups or screenshots. * One script multi-run technology reduces scripting effort and budget by which you can run one unique script to test multiple platforms. * We can write one code and run it in multiple browsers (Chrome, IE, Firefox anything) and operating systems (Android, Windows, anything). * PDF validation, average colour validation, etc. are better and stable. * We can literally automate anything (not necessarily web applications) using ZAPTEST as it works exactly as a human eye and doesn't dig into application codes. * Partial OCR and block recognization are game changers. * JIRA and ALM integration
