What is Cypress Testing?

Cypress is an open-source and free test automation tool. It is mainly used for front-end test automation. This tool is mainly developed to solve the issues that the teams face while automating an application. This growing solution for web test automation is a solid complementary framework to Selenium, which has long been the de facto web automation framework.?

This article will give you the ultimate overview of Cypress testing as well as the benefits of Cypress automation. Cypress testing benefits its users from the test creation phase through its test execution abilities.

Benefits of Cypress Testing

There are many reasons to use Cypress testing either instead of or in tandem with other web testing frameworks. Here are some of the key benefits.

1. Cypress Is More Universal

2. Cypress Automation Is Simple to Set Up

3. Cypress Has Debugging Capabilities

4. Cypress Automation Offers Fast Test Execution

5. Cypress Has an Active Community

Disadvantages of Cypress Testing

There are some disadvantages of using Cypress and they are listed below

1. It is only based on JavaScript.
2. A relatively new tool and hence, the community support is not extensive.
3. It cannot perform mobile testing.
4. Shadow Document Object Model (DOM) cannot be accessed.
5. Tabs/child windows are managed by workarounds.

Difference between Cypress and Selenium

The basic differences between Cypress and Selenium are listed below

Locator in Cypress:

?Locators are the backbone of all automation frameworks for?Web-based applications. Additionally, a locator is an identifier that tells any automation tool that?GUI elements?(?say Text Box, Buttons, Check Boxes, etc.); need to operate. Following the same concepts,?Cypress?also uses locators to identify the UI element for the application under test.?

Get and Find Command:?

Cypress?provides two essential methods?get()?and?find()?to search for the web elements based on the locators. The results for both of these methods are almost identical. But each has its importance and place of implementation.

Cypress Asynchronous Nature:

?Asynchronous programming?is a means of?parallel?programming?whereby, a unit of work runs separately from the main application thread. Additionally, it notifies the calling thread of its completion, failure, or progress. These types of programs are “non-blocking.”?When you execute something synchronously, you wait for it to finish before moving on to another task.?On the other hand, when you run something asynchronously, you can move on to another task before it ends.

Handle Non-Cypress async promises:

We know that?Cypress?internally handles the?asynchronous behavior?of its commands and still provides a seamless, sequential, and consistent execution of the test cases. Still, there can be situations, such as combining the Cypress commands with third-party libraries or JavaScript commands, where we have to handle the async promises or commands explicitly. We will learn how Cypress can help in managing these Non-Cypress?Async Promises?explicitly

Cypress Assertions:

?Assertions?are the validation steps that determine whether the specified step of the automated test case succeeded or not. In actuality, Assertions validate the?desired?state of your?elements,?objects, or?application under test.?Eg. assertions enable you to validate scenarios such as whether an element is visible or has a particular attribute, CSS class, or state. It is always a recommended practice that all automated test cases should have assertion steps, otherwise, it will not be feasible to validate whether the application reached the expected state or not.

Interacting with DOM Elements:?

Each?UI automation tool?provides some?APIs or methods?to interact with the web elements, so the designated operation can be performed on the UI element. In addition to this, these methods also assist in the needed user journey simulation. Continuing the same practice,?Cypress?also provides multiple commands which can simulate the user's interaction with the application.
