All about Cypress!!

What is Cypress.io

Cypress is an open source front end automation tools for web applications. This is a non-selenium based tool, when i say non-selenium it does not use selenium libraries neither it is build on top of selenium. Its build all from scratch and offers the following interesting cool out of the box features.
  1. Time Travel :You can travel back and see what happened when you ran the test. Before and after. How cool is that!!
  2. Debugging : You can use chrome devtools to inspect the DOM
  3. Automatic waiting : No more adding waiting through code. All batteries included !!
  4. Screenshots and videos : For failed tests the screenshots and videos are taken automatically, no more adding code explicitly.
  5. Stubs and clocks : Can be used for unit tests by the devs.

Setting up cypress

  1. Install nodejs
    1. On Mac http://blog.teamtreehouse.com/install-node-js-npm-mac 
    2. On a windows machine http://blog.teamtreehouse.com/install-node-js-npm-windows 

Creating a cypress project

Once you set up the node.js on your machine follow the below steps to get started with cypress.io
  • create a folder/directory for your project.
  • change the working directory to the newly created directory
  • run the command without quotes "npm init"
  • go on pressing enter to go with what cypress defaults to, unless you want to explicitly label
  • once the setup is over run the command without double quotes "npm install cypress"
Cypress comes up with some sample tests to run. Here is how you can run cypress.

Make sure you are in the directory where your package,json file is located (ie your project directory) and run the command without quotes "./node_modules/.bin/cypress open"

You would see a window opening and with the list of integration tests. click on any one of them to run the tests.

You can watch it here

In the next post we will explore the APIs of cypress.

Cross Browser testing for React Apps

Before we discuss the need of cross browser testing for React apps lets get a quick essence of why do people use react to develop their apps and what is cross browser testing. React React and React Native , support all the major browsers across platforms ability. It means that if one would want to build an application for iOS and android platform, all they would do is have a single code base and rest is taken care by react to make it cross platform. In addition to it the support for all the major browsers and has been tested, however with a little limitations for older browser where the polyfills are used to support them. Cross browser Testing Cross browser testing helps you validate if your application is compatible across different browsers, platforms and devices. It becomes important today to support all the major browsers and the devices as it is almost impractical to control what platform or browsers the users would use to access your application i

Challenges in testing ChatBots

        This is the second article on ChatBot Testing. Here is the first article which introduces the chatbots in general and details out why should we test chatbots.         Chatbots are different to other applications in several ways as listed below which makes them challenging to test and measure the quality. Self Learning Systems         Chatbots are built using AI and NLP services and keep learning and improving on their own. This makes it highly unpredictable whether a test case has failed due to the defect or if its improvement. One cannot have the traditional style of testing and write test cases with expected output. Remember, the test data used itself can be used by the bot to learn and update its behaviour, the negative testing may have an impact on the bot !! Non-linear input          Voice based chatbots use the speech recognition technologies to convert the voice to text. Chatbots are heavily dependent one such solutions. Along with the dependency comes
