Experience
Test Automation Framework for Universal Music
http://www.umusicpub.comA test automation framework based on Selenium using SpecFlow and C#.
I worked on a company project for 2-3 years that had Universal Music Production Group as a customer, for which I had to test the umusicpub.com website, both manually and automated. I've moved the test execution to AWS Lambda to save money and time for the test execution. I also created an internal app written in C# using WPF to allow the user to select which tests to execute and configure test parameters required by the framework. At the end of the development phase, this app was used widely across test teams working with .NET
