    Cypress doesn't like tests that take too much time to run. If a test takes too much time, Cypress can throw one of the following errors (there are GitHub issues about that - first, second). I've mentioned some ways to deal with it in this post.

    Cypress is much more recent than selenium (I first used this approach 12-13 years ago). It looks like the same sort of thing though. Anyone reading this thread: if you code for browsers but have never done any browser automation, go look at .

    You might have noticed the e2e folder. That's a fully-functioning setup of Cypress for doing integration-level or even full end-to-end tests.

    There's also the concept of E2E testing, making sure that, above the level of unit tests, the disparate parts of the code work well together. I like cypress for E2E testing. You can set it up to run on local as a pre-push hook or set it up in CI so that it runs before deploy and catches any failures.

    One of the great parts of learning Cypress is that it’s really readable. Without much experience, you should be able to go through Cypress tests and understand what the tests are testing for. To make them even more readable and to give us some extra commands, I like to add Cypress Testing Library: “Cypress Testing Library allows the use of dom-testing queries within Cypress end-to-end browser tests.”

  • Extended "run all specs" feature for Cypress 10

    As probably all Cypress fans know already, Cypress 10 was shipped without the "run all tests" feature due to "technical limitations" (they are apparently working on a solution, and here is where you can read all about why they removed it, what are the technical limitations, and all the complaints about it too)
