I recently came across "UI Testing at Scale with AWS Lambda" and I find this quite interesting. If I have understood correctly, they are running test suites in headless Chrome within a Lambda function.
I wonder if it is generally possible to spawn a GUI via AWS Lambda to run any form of GUI-based tests there (i.e. for GUI technologies without a headless mode). All I have found so far is this GitHub project which enables Xvfb in AWS Lambda.
Does anyone know and/or has experience with this?
