Cypress vs Selenium: What are the differences?
Cypress: Better, faster, and more reliable testing for anything that runs in a browser. Cypress is a front end automated testing application created for the modern web. Cypress is built on a new architecture and runs in the same run-loop as the application being tested. As a result Cypress provides better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website; Selenium: Web Browser Automation. Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
"Open source" is the primary reason why developers consider Cypress over the competitors, whereas "Automates browsers" was stated as the key factor in picking Selenium.
Selenium is an open source tool with 14.9K GitHub stars and 4.97K GitHub forks. Here's a link to Selenium's open source repository on GitHub.
MIT, Typeform, and Bukalapak are some of the popular companies that use Selenium, whereas Cypress is used by CircleCI, Intuit, and RELEX Solutions. Selenium has a broader approval, being mentioned in 777 company stacks & 443 developers stacks; compared to Cypress, which is listed in 60 company stacks and 45 developer stacks.
In the company I will be building test automation framework and my new company develops apps mainly using AngularJS/TypeScript. I was planning to build Protractor-Jasmine framework but a friend of mine told me about Cypress and heard that its users are very satisfied with it. I am trying to understand the capabilities of Cypress and as the final goal to differentiate these two tools. Can anyone advice me on this in a nutshell pls...
I've used both Protractor and Cypress extensively. Cypress is the easier and more reliable tool, whereas Protractor is the more powerful tool. Your choice of tool should depend on your specific testing needs. Here are some advantages and disadvantages of each tool:
More reliable (tends to throw fewer intermittent false failures)
Easier to read code (handles promises gracefully)
Cannot switch between browser tabs
Cannot switch to iFrames
Cannot specify clicks or keypresses explicitly as if a real user was interacting
Cannot move the mouse to specific co-ordinates
Sometimes has trouble switching between different top-level domains, so not good for testing external links
Cypress is a newer tool with less extensive documentation and less community support
More powerful because it is Selenium-based - it can switch between tabs, it can handle external links to other domains, it can handle iFrames, simulate keypresses and clicks, and move the mouse to specific co-ordinates within the browser.
More extensive community support and documentation
Slower and more brittle - in general there is a higher likelihood of cryptic and/or intermittent errors which may cause your tests to fail even though there is nothing wrong with your application
For highly experienced automation engineers, the fundamental "brittle" nature of Selenium can be worked around - it can be reliable but only if you really know what you are doing
Less graceful handling of promises - relies on async/await or .then to manage the order of execution. Therefore it is a bit harder to read the code.
Harder to set up, and the method of setup impacts its reliability. For example, a hub/node configuration where the selenium jar is on a different physical machine than the browser under test will cause unreliability in your tests. Not everyone knows about this type of thing, so it's common to find Selenium frameworks that are set up poorly.
It's probably better to use Cypress if
you're at a smaller company and have a close relationship with developers who can help write hooks or stubs in their code to assist your testing
you don't need to do things like switch between tabs or test links to external top-level domains
It's probably better to use Protractor if
You might need to switch between tabs or test external links to other domains within the scope of your framework
You want to use a more accurate simulation of how a real user interacts with a browser (i.e. click at this location, type these keys)
You're at a company where you won't have any support from developers in writing hooks or stubs to make their code more testable in a less powerful framework like Cypress

we are having one web application developed in Reacts.js. in the application, we have only 4 to 5 pages that we need to test. I am having experience in selenium with java. Please suggets which tool I should use. and why ............................ ............................ .............................
My company was looking for a testing tool that would integrate easily with AWS Amplify and quickly provide value. I created a POC for each tool we were exploring and showed it to the team (since we all want to contribute to the testing framework). Cypress was by far the easiest to go from nothing to running tests that were finding bugs in our web application.
The only difficulties I had with Cypress were working with iframes and the fact it does not currently handle new tabs. Cypress currently supports Chrome, Edge, Electron (headless) and has Firefox in beta so if IE is something you need to support, you might want to use another tool in conjunction or in place of Cypress.
Cypress is very well documented with a very responsive support team. Recently the Cypress team released the 'Real World App' as a showcase for implementing good tests with best practices.
As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.

가장 강력한 웹 UI / UX 테스트 툴 이지만, 문제도 많다. iframe 안에 있는 건 잘 select 가 안되기도 하고, 화면이 작아 컴포넌트가 화면에 보이지 않으면 또 select 할 수 없다. 하지만 브라우저를 있는 그대로 제어 할 수 있다는 게 가장 큰 매력이다.
ps. selenide 와 같이 쓰면 코드가 많이 개선된다.
Maintaining and expanding automated regression tests is one of my primary responsibilities at CrowdTwist. We use Selenium to test the front-end parts of our platform.
Used Selenium web-driver for automated QA testing in continuous integration and continuous deployment.
