Scala test cases -- 2

I am looking to hire a Freelancer to develop Scala test cases for an existing system. The work involves creating comprehensive test suites that accurately execute the functionality of the system, validate input, handle errors, integrate with any external systems and check for scalability and performance. The expected outcome is that all the test cases should pass successfully. Furthermore, extensive documentation on the project and its existing components is available. If you have the necessary experience and technical knowledge for this project, I invite you to apply.
