ask-assertions

ASK Assertions contains a number of helpers for testing common skill responses in projects built with the amazing Alexa Skills Kit SDK for Node.js.

Disclaimer

Although, this package is based on the helpers from the Single Stream Audio Skill, it is in no way affiliated with or endorsed by Amazon or the Alexa team.

Installation

Install ask-assertions as a devDependency:

$ npm i -D ask-assertions

Note: ask-assertions requires the following peerDependencies

• ask-sdk-models >= 1.11.x
• chai >= 4.2.x

Usage

Example using mocha + chai with TypeScript.

import "mocha";
import * as assertions from "ask-assertions";
import { ResponseEnvelope } from "ask-sdk-model";

import { handler as skill } from "../src/index";

let skillResponse: ResponseEnvelope;

describe("AMAZON.HelpIntent", function testHelpIntent() {
  before(() => {
    this.timeout(5000);

    return new Promise(resolve => {
      skill(helpIntentRequest, null, (_, responseEnvelope) => {
        skillResponse = responseEnvelope;
        resolve();
      });
    });
  });

  it("should return a valid skill response", () => {
    assertions.checkResponseStructure(skillResponse);
  });

  it("should return valid output speeach", () => {
    assertions.checkOutputSpeech(skillResponse);
  });

  it("should say 'This skill can do cool things'", () => {
    assertions.checkOutputSpeechContains(skillResponse, "This skill can do cool things");
  });
});
