AWS Brings The Express Testing Capability In Amazon Lex

The new express testing capability enables you to accelerate iteration, test ideas, and make rapid design decisions.

Recently, AWS announced the express testing capability in Amazon Lex.
Amazon Lex is a service for building conversational interfaces into any application using voice and text. Lex provides the same deep learning technologies that power Amazon Alexa to any developer.
Amazon Lex now offers the express testing capability on the AWS Management Console in order to expedite building your chatbot. Users can start testing their bot soon after they initiate the build process without having to wait for the entire build to complete.
This express testing capability allows developers to test only exact matches with training data. You can now quickly iterate through the build and test phase, reducing the overall time required to deploy a bot in production.
When you choose your Build, Amazon Lex starts preparing the build for express testing. Users can view the status using the test window. When the build completes for express testing, users can test utterances that are an exact match to the sample utterances in the test window.

Users can test the dialog management, confirmation prompts, and the validation and fulfillment code hooks and responses. Amazon Lex executes the build process in the background.
