Cypress
What is Cypress?
Cypress tests anything that runs in a browser. The Cypress app is architected to handle modern JavaScript frameworks especially well. We have hundreds of projects using the latest React, Angular, Vue, etc. frameworks. Cypress also works equally well on server rendered applications.
Cypress Cloud is an essential web-based companion to our open-source app. It records tests run in Continuous Integration so you can understand failures and share results with your team.
Who Uses Cypress?
Front-end developers and QA engineers that write automated tests and are tired of testing being a headache. For them, Cypress make testing faster, easier, and much more reliable.

Reviews of Cypress

Cypress is easy and single packed
Comments: I am working as an automation engineer where I feel cypress is easy to install and get rolling. I like its outstanding features including time-travel, video, screenshots and so on. It has some issues as well but I prefer using Cypress to other automation tools.
Pros:
This automation tool is very easy to install and write tests. The thing I liked most in cypress are given below: i. No need to install extra driver for browser. ii. It uses JS and very suitable for single page applications. iii. Single line of code will install the cypress in your machine. iv. I really love its features like time travel, video recording and image capturing, auto waiting and so on.
Cons:
I have found some issues in cypress. They are working on to fix these issues. i. It does not support multiple browsers which is not be suitable for some tests. ii. "Detached from DOM" this is the common issue I have encountered.
Alternatives Considered:
Cypress is a great flexible test framework
Comments: having been using Cypress for 6+ years, I still enjoy working with it on a daily basis.
Pros:
constantly evolving, always a new feature in developmenteasy to learn and implement
Cons:
not able to use on mobile app development

A step forward for e2e, but still too many bugs for comfort
Pros:
The display for your e2e tests at every step is really what i always hoped for an e2e testing software
Cons:
Is not reliable. Tests that are ran 3 times in a row, will work 1 or 2 of those times and it has nothing to do with anything you did. Debugging often gives the wrong or useless information.
Alternatives Considered:
Quick and easy testing for everyone.
Comments: I am working with Cypress for over 3 years. This framework is reliable, fast, and user-friendly. Failed tests debugging is enjoyable with a detailed open mode console. The amount of functionalities is amazing and its usage usually is just as simple as entering one or two methods. Each test is recorded/screenshotted if failed. Adaptation to users' needs is vast - multiple configs if needed, different types of tests (frontend, API), a huge amount of open-source plugins ready to work within two terminal commands, and much more. Documentation, as well as customer support, help greatly with all problems and questions. In 95%, if you have a bug, somewhere there is a solution. However, Cypress has some downsides, like a lack of native parallelization support (which needs an external cloud). Some functionalities (because of the framework architecture) are not supported (iframes) or resolved in a strange way (real mouse hover). Also, the structure of the tests (cy.get...) may be confusing at the start, especially since it is completely different from Selenium syntax. To sum up this review, Cypress is an amazing piece of code, that helped me greatly through the years. It has some specific problems and a unique structure, but when understood and used correctly it is extremally powerful and can be widely implemented to handle apps testing.
Pros:
Simplicity. Customer support. Documentation. Functionalities - Shadow DOM, DOM manipulation, debugger, videos and screenshots, automatic wait, etc. Open mode with all execution details. A number of additional plugins and ease of implementation. Frontend, Backend, and API testing support.
Cons:
Poor support of parallelization, iframes. It may be not intuitive. Minor bugs specific to this framework.
One of the best UI automation testing tools
Pros:
One of the most powerful features with Cypress is the test runner. You can else debug any tests with ease with their time machine feature where a user can click on cypress steps to view a screenshot of the app and view the DOM. This has helped us create more confidence than other low/no code solutions. Our web team is loving this and enjoy writing tests!
Cons:
It can be tricky learning how Cypress works and how to effective write tests. The rich documentation helps with the basics and provide recipes for more advanced scenarios. The community outside of the docs are very helpful with any questions.
