dynamic dropdowns: Enter the value and click on the value.

What is Cypress?

Cypress is a javascript based entry and testing framework. It is built on top of the mocha which is again a feature in the javascript test framework learning on Algiers and in the browser making asynchronous testing simple and fun.

Cypress also uses chai or BDD and TDD assertions library for note and the browser that can be paired with any javascript testing framework.

Additionally, Cypress is a free open source that is focused on developers and QA engineers. You can do Unit testing, integration testing, and internal testing by writing test cases using Cypress.

Using Cypress, You can basically test anything that can run inside of a browser.

Does Cypress use Selenium?

And the answer no. Cypress does not use selenium. Cypress is one of the free popular test automation tools that does not run on Selenium along with puppeteer. Cypress runs tests directly inside a browser.

Basically, Cypress executes in the same loop as your application runs which is one of its greatest advantages.

Compared to the selenium frameworks, Cypress executes commands outside your application through the network.

What are some of the Cypress features?

The first is automatic waiting. Cypress automatically waits for the DOM to load, the element to become visible, and the animation to get completed.

Other cool features are for example Time Travel, the ability to control network traffic, or video recording of the test runs and taking screenshots on the failed test.

Last but not least is debug ability. Cypress gives you the ability to directly debug your application under a test from the DEV tools. It not only gives you straightforward messages but also suggests how you should approach them.

What makes Cypress different?

The first thing is architecture. Most distinct tools operate by running outside of the browser and executing remote commands across the network. Cypress is the exact opposite. Cypress is executed in the same loop as your application.

Cypress ultimately controls the entire automation process from top to bottom. Cypress is also having ultimate control over your application, network traffic, and easy access to every host object and that unlocks a new way of testing that has never been possible before.

And last but not least is shortcuts. This means you do not have to visit the login page and type username and password and wait for the page to load but you can basically take a shortcut and programmatically look into your application

Which programming languages supported in Cypress?

And the answer is simple.

There is only one programming language supported and that is javascript. Unfortunately, no other languages are supported, and also have no plans to add support for languages.

So if you need to write your automated tests for example in Python or Java you have to consider using a different tool probably on selenium webdriver.

What is a fixture?

Basically, fixtures are used as external pieces of data that can be used by your test. fixture files are located in Cypress fixtures by default but you can configure them to other directories.

You will typically use them with the cy.fixture() command and most often manually stubbing your network requests.

Which browsers are supported in Cypress?

Cypress supports Google Chrome,electron,firefox,chromium,Microsoft edge.

Does Cypress support Xpath?

And the answer is No.

Cypress has no native support for Xpath. Cypress basically leverages the Jquery powerful selector engine to help make that familiar and readable format for developers.

In effect, Cypress bundles Jquery and exposes many of its elements. So you're going to work with the complex HDMI structures with ease.

But there are few third-party libraries that allow you to use Xpaths in your Cypress test.

How do you handle multiple Windows in CypressIO?
