Simulate a device that supports video

[clara-jr]

Using the condition .withInterfaces({ video: true }).build() to build a request does not set the handlerInput.requestEnvelope.context.Viewport.video to true in order to simulate a device that does support video. It only changes the value of handlerInput.requestEnvelope.context.System.device.supportedInterfaces.VideoApp.

Do you think it's possible to add something like this in the RequestBuilder?

if (this.settings.interfaces.video) {
  ctx.System.device.supportedInterfaces.VideoApp = {};
  ctx.Viewport = { video: true }
}

Happy to change that. Could somebody please verify this or link to docs explaining this? I want to make sure that this will always be true

I can share these links:

• https://developer.amazon.com/en-US/docs/alexa/alexa-presentation-language/apl-interface.html#viewport-object
• https://developer.amazon.com/en-US/docs/alexa/alexa-presentation-language/apl-interface.html#video

in which the Viewport object included in the Alexa requests and the video property are explained. The Viewport object contains information about the supported viewports for the user's device. Particularly, the video property would be an object including an array representing the available technologies for playing video on that device. If the device does not support playing videos, the video property will not be present. So I think that to simulate a device that supports playing video it's enough to make that property exist (or be truthy).

Sorry for the delay. Sounds reasonable. Would you be able to provide a PR for this?

Sure! Here it is:
