But if there is one testing framework that is becoming more and more popular thanks to its ease of use and its advantages over the previous ones, it is Cypress.<\/p>\n\n\n\n
What is Cypress?<\/strong><\/h2>\n\n\n\nCypress is an open source framework<\/em> for automatic front-end<\/a> testing<\/a> of JavaScript-based web applications. Its use is not limited to E2E tests, but also allows the creation of integration or unit tests.<\/p>\n\n\n\nSince it has its own assertion libraries, custom commands and other interesting features (e.g. a dashboard for debugging and running our tests), Cypress has proven to be a versatile framework adapted to the characteristics of the modern web.<\/p>\n\n\n\n
All of this is based on an architecture that was built from the ground up: You don’t have to start with Selenium.<\/p>\n\n\n\n
This allows us to work with a framework that does not require the installation of external tools and libraries to start building our tests.<\/p>\n\n\n\n![\"\"](\"https:\/\/wata.es\/wp-content\/uploads\/2023\/04\/MicrosoftTeams-image-48.png\")
<\/figure>\n\n\n\n<\/div>\n\n\n\nWhy Cypress?<\/strong><\/h2>\n\n\n\nDue to the development of web applications and the emergence of current and modern JavaScript-based frameworks such as Angular<\/a>, Vue<\/a> or React, E2E testing frameworks have also evolved. Considering the versatility and ease of use that Cypress offers, the popularity it has gained since its development is to be expected.<\/p>\n\n\n\nAnother interesting feature of Cypress is that this framework runs the logic of our tests in the same execution cycle as the application. Cypress runs a NodeJS process that reacts to the events of our application in real time, without us having to use WebDriver to run our tests.<\/p>\n\n\n

<\/figure><\/div>\n\n\n<\/div>\n\n\n\nCypress also makes it easier for us to develop tests, as you only need basic knowledge of JavaScript to get started. Assertions from other well-known test frameworks such as Chai and Mocha are also used.<\/p>\n\n\n\n
Another important reason for using Cypress is, of course, the dashboard. A graphical interface where we can follow the process and execution of our tests in real time, as if we were in the place of the user, so that we can debug and have a direct overview of the errors that occur in our tests.<\/p>\n\n\n\n![\"\"](\"https:\/\/wata.es\/wp-content\/uploads\/2023\/04\/MicrosoftTeams-image-52.png\")
<\/figure>\n\n\n\n<\/div>\n\n\n\nRelevant features of Cypress<\/strong><\/h2>\n\n\n\nCypress has many features that are advantageous over other frameworks and that can help us decide to use it as an E2E testing tool for web projects.<\/p>\n\n\n\n
1. current state of the framework and learning curve<\/strong><\/p>\n\n\n\nCypress is a modern and up-to-date all-in-one<\/em> framework with good documentation, an active community and continuous updates.<\/p>\n\n\n\nIt offers a quick setup of the framework in our project, as installation is fast and very little configuration is required. The tests are written in JavaScript and the Cypress library has descriptive and concise commands.<\/p>\n\n\n\n
All this contributes to a flat learning curve for both the development team and the QA team<\/a>.<\/p>\n\n\n\n2. Integration (or not) with other technologies.<\/strong><\/p>\n\n\n\nCypress does not require integration with Selenium because the architecture is built from scratch. In general, it does not need to integrate with other external libraries and frameworks, but we can do so if we want to extend the functionality of the framework with well-known technologies such as Mocha, Chai or jQuery.<\/p>\n\n\n\n
It also works with any JavaScript-based library or framework that runs in a browser.<\/p>\n\n\n\n
3. interaction with browsers<\/strong><\/p>\n\n\n\nWith Cypress, there is no need to install a browser as the headless<\/em> browser (no graphical interface) allows for faster and less time-consuming execution. This would eliminate the need to install a browser to run the E2E tests through continuous integration<\/a>.<\/p>\n\n\n\nOn the other hand, we do not need to run a WebDriver in Cypress, as our tests are executed within a browser by a NodeJS process.<\/p>\n\n\n\n
Since it has its own assertion libraries, custom commands and other interesting features (e.g. a dashboard for debugging and running our tests), Cypress has proven to be a versatile framework adapted to the characteristics of the modern web.<\/p>\n\n\n\n
