Visual UI Testing: Testing the Last Mile
Craig Cavalier - ezCater
Some things can't be easily tested with unit tests and integration tests, and so far too frequently we rely on manual QA to verify visual changes to our applications. With a proliferation of device sizes and browser versions, spot checking changes in the browser is not possible at scale. In this talk, Craig Cavalier explores how visual ui testing can close the testing gap and restore confidence in our ability to make UI changes that work cross-browser.

Repo Architectures for Sharing Components - David Colwell
Просмотров 3925 лет назад
As UI developers we'll eventually come across situations where we want to break out a specific subset of code we're working with into it's own separate project so it can be shared or worked on as something independent of what we consider the primary app(s) we're working on. This could be as simple as a shared UI component library, more complex such as functional or utility modules we want share...

awesome video 👍
His confidence is next level 👍
Awesome introduction to hooks, thanks.
Excelent cleared the concept of Use effect for me I'm stuck on the concept of reducer but will understand that too
peace and freedom for the people of Ukraine 🇺🇦 ✨

"How do you think French people write their code!? " .... "in English.."
Goated Video
Spected some hee hee's, very disapointed
Kick a$$ presentation
Michael presentation was awesome.
You try to give the video more brightness it will be great if you do
I think he forgot to turn off the night shift mode on his laptop since it was already at 8pm.
Ryan has explained very well about react hooks which might solve the bug of re-rendering of useState while used with useeffect. Thanks Ryan 🙌
I wonder how many people in the audience got what he's saying... Because it took me about a year to really get what he's sowing there lol :D Examine me chat: Hooks are a way of sharing stateful logic before hooks the patterns for sharing stateful logic were HOC's and render props but they had their drawbacks and weren't as clean as hooks. This is how I understand it.
Hi Team Can you change this title to, What React Abstract? or Data Structure used by React for Batching
Very informative and fun presentations as usual <3
Where is Michael Jackson?
So subsribetopost does not call the callback when cleaned up? Because that will be setState on unmounted component a.k.a memory-leak.
Nobody: Someone teaching React: Look at this COUNTER
if you put the ++ in the backend then it ... but if you put it in the frontend it returns also the value. Great terminology! :D
Shall we play a game? > Global Thermonuclear War (enter)
The Michael part was a serious eye-opener for me.
you probably dont give a damn but does any of you know a trick to get back into an instagram account..? I was stupid lost my login password. I appreciate any tips you can give me!
@Chandler Moshe Instablaster ;)
@Achilles Arturo i really appreciate your reply. I got to the site thru google and im waiting for the hacking stuff atm. I see it takes quite some time so I will reply here later when my account password hopefully is recovered.
@Achilles Arturo It worked and I finally got access to my account again. I'm so happy:D Thank you so much you saved my ass !
@Chandler Moshe no problem xD
this is hilarious
Did you catch the bug that slipped in the hooks version?
The amount of shade in this talk from Ryan is hilarious.
I thought this was a video of Michael Jackson, The King of Pop ®, coding 😐
12:27 Yes, but actually no. When you do ++x it adds 1 to x and evaluates to its previous value. x++ is the same except it evaluates to the new value of x. For example: console.log(x++); is the same as x = x + 1; console.log(x); and console.log(++x); the same as console.log(x); x = x + 1;
Nope, it's the opposite.
cool
5:35 dude you are either stupid or dumb or both. what kind of logic is that? :D it's like you are posting to db some data and saying: "ovv i am posting to a db it gives me number and also cows. it's wierd". you should change your mindset.

This guy is awesome
The guy in the background is trying way tooo hard
"tuplé" I've lost on it
Jesus fucking Christ for god fucking sake can you type any fucking louder and harder??
The arc animation solution no longer works AFAIK for the current version of deck.gl
i got it to work yesterday :)
What is the name of this editor, vs code ?
I am just learning front end, I wish I will be that fast on my keyboard and text editor one day
This is all just Monads lmao.
Yeah be these are all JS developers lmao

Props to Michael for not shortening his first name to Mike

Awesome!! Thanks!
Awesome
Let’s see a vote for all devs who are in favor of merging all the major .js frameworks into one and consolidating their features in order to simplify learn time and reduce code. Anyone want to start a foundation to do it? Call it Consolidate.js.
SetState actually seems more like magic than hooks to me.
Awesome!!!! Thank you
Wow! This could have been the best tutorial....but...
First guys sucks
"it's a tuple" LMFAO
second one too.
That syntax theme is amazing. What's it called? (Great presentation and all.. :) )
I prefer Angular :) You guys write functions and call it Hooks... damn Stoneage coders.
First understand what is a hook and how it's used and then talk thick boy
Because you don't know why the word hook is used. If you prefer angular then it's good but don't just speak rubbish
Hooks and Components are not just functions.
