Announcing the express testing capability in Amazon Lex
Amazon Lex now provides the express testing capability on the AWS Management Console to expedite the chatbot building process. Amazon Lex is a service for building conversational interfaces into any application using voice and text. With the express testing capability, you can start testing basic interaction elements such as the conversation flow, prompts, responses, and fulfillment logic soon after you initiate the build process without having to wait for the entire build to finish.
