Cypress is a complete testing solution for web developers. It uses a browser-based test-runner to visually validate your JavaScript code and makes test-driven development fun.

have you ever looked into Playwright? if so, what are your thoughts?

@rasmusfalk-jensen8221 2 года назад

@@StEvUgnIn That is just not true. Both WebdriverIO and Protractor were built for testing purposes. While Selenium might just be a tool for browser automation, it has seen wide use for testing purposes as well.

@recnepSpencar 2 года назад

@@StEvUgnIn You’re not wrong that it can be used for scraping. Any E2E tool would do the trick well. It’s primary purpose thing is testing. Puppeteer is more what you’re thinking of for scraping.

Cypress is pretty fun, but sometimes really tricky. The funniest part of it for me was when I had to do conditional testing, and I was new to Cypress. I relied on the docs and I found a section for conditional testing. It states: "don't worry, there are ways you can do with conditional testing! for example, you can... remove the need to do conditional testing!" Thank you Cypress, very cool. PS: No, I couldn't do that

@MrBloodySpirit 2 года назад

For me, I moved from Cypress to Playwright. It's much faster and can do almost everything Cypress can!

@JPeetjuh 2 года назад

That, and, so much of Cypress bugs me. Its Promises are not actual native browser Promises and can't be awaited. The magic strings for assertions. And if I wanted to see how many rows a table has, then submit a form and check if that table now has count + 1 rows, Cypress seems to actively hinder me. I found Playwright much more intuitive, friendly and robust. The only thing I really liked about Cypress was its execution window where you could "time travel" as Jeff says.

@threewestwinds 2 года назад

@@JPeetjuh The promises thing is super annoying, and agree that the magic strings are not my favorite way of doing assertions. Even though it has a promises-like API, Cypress is actually a command queue, not a promise chain. The use of promise-like syntax (and especially the docs trying to say it's promise-based) is very misleading, 100%.

@graffhyrum 2 года назад

The cross domain restrictions and local single threading are also pretty annoying.

@nathanlamaire 2 года назад

Good thing about using these tools is that it also helps you to narrow down use-case of the application you make and only implement essentials.

@darkknightdks 2 года назад

Absolutely love your videos. I have been using Cypress for over a year now and I don't want to go back to those Protactor, Selenium stuff. Also, Cypress has something called `data-cy`, which is added to the elements that you want to loop up in your tests. `data-cy` parameter can have a unique name and enables the test to directly find the element in the dom. This is an amazing feature that we use everyday and avoid looking up using html and css tags as they can change.

@nicolasramos7084 2 года назад

I've literally started working with cypress for our application at work this morning. Awesome timing as usual

@PfhorShark 2 года назад

Been using cypress for 3 years after using selenium for god knows how long. I highly recommend this for TDD, your feedback cycle is almost immediate, you aren't coupled to chrome/driver versions, it's altogether the best way to write your integration tests first, see them not work, then repeatedly do the next thing it said didn't work. Simple.

@galgrunfeld9954 2 года назад

I've been avoiding learning testing for years just because it was so boring for me. Even when I sat down with myself and asked myself what technologies I should learn to become a better well-rounded full-stack developer, testing was in there, but was always the last one I wanted to do. So I learned a few technologies, but never picked up testing. But this framework makes me actually want to learn it, seems so cool!

@joshuaokoro9447 2 года назад

@@galgrunfeld9954 I ran away from testing for so long until I started seeing the importance. Especially working with a team with constant update, testing would catch a lot of bugs before it gets to staging or production. These frameworks have made it enjoyable so that’s a bonus. Funny thing, I’m the one now rooting for testing

@galgrunfeld9954 2 года назад

@@joshuaokoro9447 yeah, I'm very much aware of the benefits. Luckily, or maybe not, I so far worked only in small teams and did a lot of things independently so TDD wasn't much of a necessity, but I can definitely see it being crucial in so many places.

I like Cypress, it really does work like a charm. One thing to note is that the Electron runtime is bundled / baked in, which arguably is pretty stupid. There is no way to install Cypress headless, even though most people use a real browser to run tests.

@DaraulHarris 2 года назад

> There is no way to install Cypress headless I was wondering how I might use it to do my automated testing in gitlab-ci. The docs mention being able to do this, though.

@threewestwinds 2 года назад

@@DaraulHarris Cy can absolutely run in CI. Doing an npm install also downloads the cypress binary, which is fairly large, and comes with electron baked in.

Cypress's coming support for cross-domain communication (and the Sessions API) should make auth a lot less painful. Of course, "It's coming" is not the most useful answer. ^^;;
