Cypress.io

Cypress is pretty awesome as it doesn't rely on Selenium, meaning that it's super fast and reliable.

Pros:

Easy to setup and use

Cons:

No cross browser tests: only Chrome

We use Cypress on our team and it's awesome!

Looks like a great utility product.

Amazing testing tool for frontend developers. The cypress team just get's our pain in this area.

Pros:

Easy to use for frontend developers.

Cons:

None!

We use Cypress at where I work and it's incredibly powerful! We have had some problems with the blur and focus function where we have used the click function instead (for focus click on element and blur click on another random element without an event binding). Another thing I personally think could be improved is the error messages. It doesn't seem to return back a line number of where the error or test failed, so you will have to find it by yourself.

I'm using cypress and while it's super easy to setup and use there are a ton of things you can tweak to make it fit your needs. I'm using it to test the critical paths in my react application and so far everything has been working perfectly fine.

Cypress is awesome. It's probably the best e2e testing frameworks that exists. Their liaisons in the community are equally awesome. There's tons of trainings and presentations on the product all the time.

Pros:

Very easy to use. I love the little details. Much better than protractor.

Cons:

Doesn't come built in to angular. :-(
