Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Bot Tester for Bot Builder Framework CircleCI npm version Coverage Status

Simple framework that allows for easy testing of a botbuiler chatbot using mocha and chai.

install

npm install --save bot-tester

supported test libraries

  1. mocha/chai
  2. ava

Class definitions, see the BotTester Framework reference docs

config

config can be set one of 2 ways:

  1. creating a bot-tester.json file in the root directory of your project.
  2. passing in a config object into the options param when instantiating new instances of the BotTester

Passing in the config overrides any default values or values set by bot-tester.json. At the moment, the options are:

{
    defaultAddress: botbuilder.IAddress,
    timeout: number // in milliseconds
    // each filter returns false for messages that the BotTester should ignore
    messageFilters: ((message:IMessage) => boolean)[],
    ignoreTypingEvent: boolean,
    ignoreEndOfConversationEvent: boolean,
    // Setting this to true will cause checkSession to hang and test to fail.
    ignoreInternalSaveMessage: boolean,

    // this will allow using different assertion libraries. Currently supported libraries are:
    // 1) chai
    // 2) ava

    // should this field not be provided, it will default to chai
    assertionLibrary: string,

    // certain test runners need to pass in a context. Currently, the following runners require this
    //    1) ava
    testContext: {}
}

if timeout is defined, then a particular runTest() call will fail if it does not receive each expected message within the timeout period of time set in the options.

additionally, config can be set by using the config updating options in the build chain, documented below in the example use

For a more in depth view, check out the Bot Tester Framework Config doc

Test runner setup

Mocha/Chai

const { UniversalBot } = require('botbuilder');
const { expect } = require('chai');
const { BotTester, TestConnector } = require('bot-tester');

describe('BotTester', () => {
    it('can handle a single response', () => {
        const bot = new UniversalBot(new TestConnector());

        bot.dialog('/', (session) => {
            session.send('hello!');
        });

        const botTesterOptions = {
            // the assertionLibrary field can be set in the bot-tester.json, but the default is mocha/chai. It can be omitted if the desired assertion library to use is chai.
            assertionLibrary: 'chai',

            // testContext is not used for chai expectations
        }

        return new BotTester(bot, botTesterOptions)
            .sendMessageToBot('Hola!', 'hello!')
            .runTest();
    });

Ava

const test = require('ava');
const { UniversalBot } = require('botbuilder');
const { BotTester, TestConnector } = require('bot-tester');

test('can handle a single response', (t) => {
    const bot = new UniversalBot(new TestConnector());

    bot.dialog('/', (session) => {
        session.send('hello!');
    });

    const botTesterOptions = {
        // the assertionLibrary field can be set in the bot-tester.json, but testContext must be passed in for ava tests
        assertionLibrary: 'ava',
        testContext: t
    }

    return new BotTester(bot, botTesterOptions)
        .sendMessageToBot('Hola!', 'hello!')
        .runTest();
});

Example Usage

All examples use mocha/chai, but the content will be similar regardless of the test runner

import { IAddress, IMessage, Message, Prompts, Session, UniversalBot } from 'botbuilder';
import { expect } from 'chai';
import { BotTester, TestConnector } from 'bot-tester';
import { getAdaptiveCard, getAdaptiveCardAttachment, getAdaptiveCardMessage } from './adaptiveCardProvider';

const connector = new TestConnector();

describe('BotTester', () => {
    let bot;

    beforeEach(() => {
        bot = new UniversalBot(connector);
    });

    // ... tests live here!

            .sendMessageToBot('Hola!', 'hello!', 'how are you doing?')
            .runTest();
    });

Test for random response arrays

    // re-run the test multiple times to guarantee that multiple colors are returned
    let randomResponseRunCounter = 5;
    const randomColors = ['red', 'green', 'blue', 'grey', 'gray', 'purple', 'magenta', 'cheese', 'orange', 'hazelnut'];
    while (randomResponseRunCounter--) {
        it('Can handle random responses', () => {
