I am trying to use the sample code provided for Amazon Alexa API, and trying to run hello world / history buff examples through the computer. How do I test from my local machine, about the request and response formats. In the README file it is given to visit this website : http://echo.amazon.com/#skills, but I could see nothing there as it mentions more about connecting to the device. I dont have the device, but I would like to test things locally through my laptop.
Yes, the Test tab in the Alexa Developer Console allows you to interact completely with your skill during development.
You will type in your utterances instead of speaking them, but from a program logic perspective, there is no difference.
The Test page also provides a place to type in your skill's reponses, to see what they'll actually sound like. I recommend that you do so if you don't have an actual device. Sometimes adding or removing a comment can help make the responses easier to understand, or sound more natural.
