Artificial intelligence (AI) is a huge-ranging department of computer technological know-how worried with constructing smart machines capable of completing tasks that commonly require human intelligence.

The introduction of #DeFiLendingPlatforms based on #Blockchain technology in the financial sector has eliminated middlemen & reduced the delay in process. The benefits like cost & time saving is making it the first choice to implement in businesses.

What more advantages does it have to offer? Take a quick read

There are many Tech bloggers in India, who make people understand technology by their blogs.

Introduction to Automation Testing with Cypress for the Modern WebAbout Cypress

Cypress is a front end automation tool created for the modern web. Cypress is built using new architecture and it runs in the same run-loop as the application under test. This results in Cypress providing better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website.

Cypress’s Features

Some of the key features of Cypress are Time Travel, Debug ability, Automatic wait, Spies, Stubs, and Clocks, Network Traffic Control, Consistent Results, Screenshots and Videos

What you may like:

Cypress does not use Selenium as most of the other end to end testing tools are using Selenium, that’s why others have almost the same problems

Easy and effortless installation and updating. If you’re using Node.js and want to install Cypress in the project it will be just a single line in the console. (npm install cypress)

Cypress supports any framework or website quite well. There are thousands of projects built using the latest React, Angular, Vue, Elm, etc. frameworks. Cypress also works equally well on server-rendered pages or applications.

Cypress tests are only written in JavaScript. While one can compile down to JavaScript from any other language, ultimately the test code is executed inside the browser itself. There are no languages or driver bindings – there is and will always be just JavaScript.

Cypress has no issues with nodes, their versions, and related dependencies.

It has an awesome dashboard and a preview window. Just look at the screenshot below. It gives you a precise overview of what’s being tested.

Screenshot for every step, of the script, which can be quite helpful if there, is any false passing or failing test which is good for debugging also.

The broad range of debugging and testing tracking options. The list has integration with dev tools, screenshots, snaps, etc

Headless option and ease of integrating with CI. At present, Cypress can be integrated with around 15 CI providers. Cypress runs much faster with end to end tools.

Network traffic control. i.e. Detection, debugging, verification, waiting for requests

Eliminating all sorts of timers. Cypress features a built-in mechanism to handle waiting for DOM elements

Easy to use & intuitive syntax (Mocha and Chai are all there)

Wide range of selectors plus Cypress ‘built-in’ commands serves all requirement

What you may dislike:

The structure is different from the other Selenium end to end tools, so in the first place need to spend more time understanding.

Community: As Cypress is relatively new may find trouble getting answers

No native event handling capabilities like files upload etc. & No cross-browsers testing.

No Page Object Model, It supports an altogether different approach

It’s only available for only one client (language) i.e. for JavaScript only.
