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.

This is a fantastic product for testing Javascript front ends. Quick & easy to become productive.

5.0 7 years ago

Comments: Cypress.io has made writing Javascript tests a pure pleasure. It even allowed me to do testing (integration and end-to-end) on software that was written only with JQuery and mostly anonymous functions that, as a consequence of this structure, was not able to be unit tested (which Cypress can also handle). This software is more full-featured than competing Javascript testing suites, and it makes the use of Selenium purely optional (and not necessary for me).

Pros:

Second-to-none documentation. Open source with a paid model for special services (but the open-source portion is complete). Comes bundled with JQuery, mocha, and a number of other extremely useful libraries. A key point to understand in starting with this software is that all selectors (such as cy.get() ) will keep trying until a timeout is reached. You can do either a positive selector or negate the selector (test for element to not be present in the DOM). This approach is extremely powerful. The selectors themselves, in this case, act sort of like assertions in that tests fail if the selector condition times out. Each subsequent cy.xxxx() command is only executed after the previous cy.xxxx() command completes - either the selection condition is met or it times out, so it's easy to prevent undesirable asynchronous behavior. Assertions are made using Chai, and tests are framed using Mocha syntax. I love that assertions are very English-like. Cypress.io comes with client software that spins up a browser and runs the tests. After the tests complete, you can review DOM snapshots of the test, which provides a way to play the state of the tests back over time. You can write not only unit tests, but full integration and end-to-end tests. I can't say enough good about Cypress.io. I thoroughly enjoy writing tests now, and need no other testing product for the front end.

Cons:

I've only found one small thing - the way the cy.visit() command is set up. The command is set up like this cy.visit(baseUrl + the url). I would like to see it set up to be cy.visit(host + baseUrl + url).

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.

A step forward for e2e, but still too many bugs for comfort

3.0 4 years ago

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.

One of the best UI automation testing tools

5.0 2 years ago

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.
