Http mocking for Luis.ai

Luis Mocker

Easy http mocking of luis.ai. Perfect for testing services that rely on Luis.ai by making them deterministic and avoiding pay per call requests.

This is a work in progress. PRs are welcome!

installation

npm install -save luis-mocker

constructor(luisModelUrl)

mock(utterance, responseBody)

• mock utterance is the string that is expected.
• responseBody is the response sent back when that utterance is checked. Bodies can be easily built with the LuisResponseBuilder

example use

const Promise = require("bluebird");
const chai = require("chai");
const { DateTimeV2, LuisResponseBuilder } = require("luis-response-builder");
const rp = require("request-promise");
const LuisMocker = require("./../src/LuisMocker");

describe('LuisMocker', () => {
    const july15AmbiguousDateEntity = DateTimeV2.createDateTimeV2_Date_EntityWithAmbiguousDate('July 15th', 0, 4, new Date('7/19'), new Date('2015'));
    const cancelTacoBellResponse = new LuisResponseBuilder('I want to cancel my reservation at Taco Bell on July 15th')
        .addCustomEntity({ startIndex: 0, endIndex: 4, type: 'restaurantName', entity: 'taco bell', score: .98 })
        .addPrebuiltEntity(july15AmbiguousDateEntity)
        .addIntent('cancel', .92)
        .addIntent('login', .3)
        .addIntent('none', .02)
        .build();

    it('can mock requests to luis.ai', () => {
        return rp.get(cancelTacoBellUri, { json: true })
            .then((cancelTacoBellTestResponse) => {
                chai.expect(cancelTacoBellTestResponse).to.deep.equal(cancelTacoBellResponse);
            })
});
