lex automated tests

Here is what AWS recommends: https://aws.amazon.com/blogs/machine-learning/using-a-test-framework-to-design-better-experiences-with-amazon-lex/

Amazon Lex has an automated testing tool built into the service called “Test workbench”.

I added a video on YouTube about it a while back. Check that out and our documentation pages for the feature. You can use the console to create and run tests or you can also run tests using APIs.
