I am looking for a testing framework to kind of test the front end and design of my application. I am building an angular application and we are using Protractor for the end to end tests, however I was wondering how do we test the design and the actual layout.
For instance when my partner pushed code last week he broke the navigation menu barand we want to make sure we have automated test that makes sure that the css is not broken before we push it in to prod. I am open to all suggestions. I was wondering if protractor can be used for this or is there a a better tool?Protractor does give you ability to localte css elements by id etc but not sure if this is a smart approach.
It might not provide everything you need, but BackstopJS seems to be capable of handling CSS breakage:

I am very new to UnoPlatform. I am trying to create a new application. Yet for some time I am stuck at creating convenient way to navigate through views.
I searched through webs and forums. I found that the best design pattern would be MVVM. Demo Apps on platform.uno seems to be implemented using this pattern as well. However some approaches i found online are not possible with unoplatform, as far as I understand it.
To give an example:
The app starts at LoginPage. On successful login I want to be taken to a completely different view with different controls. One of the approaches I found is by holding currently active viewmodel and render pages accordingly.
Is there some approach you would recommend for navigating through views? Or some material I could read to understand this concept better?
Using MVVM Light, the navigation needs to be performed using the NavigationService, as you'll find in this documentation: http://www.mvvmlight.net/doc/nav5.cshtml.
You can also use Prism for Uno, which handles navigation per regions. You can find documentation here https://prismlibrary.com/docs/ and samples here: https://github.com/PrismLibrary/Prism/blob/c71957ad56c0cfedf479d46dcb1870c96232d86c/e2e/Uno/HelloUnoWorld.Shared/ViewModels/ShellViewModel.cs#L30

Is it possible to scrape data automatically from websites that require a validation code each time a webpage is accessed? Such as the case when the website shows you a picture of the code and asks you to enter what is shown in the picture. I'm using the rvest package. Is this possible to do?
What you're trying to do is beat CAPTCHAs. That's possible but very hard. This is a spammer's hardest job - to come up with an algorithm smart enough to fill out those fields correctly. It's not something you're supposed to do, the whole point of those validation codes is to prevent access from non-humans. If you're smart and motivated enough to figure out how to answer those questions programatically, you can probably make more money doing that than whatever you're trying to do :)
Some websites offer a direct API, which is the way you're supposed to interact with their data. But getting past a CAPTCHA by scraping is not an easy deed.

While Single-Page application approach is rising as a web development choice, I still don't understand, practically, how would losing the ability to go back/forward in the browser be an O.K sacrifice? Imagine Facebook without direct page navigation! Is there an essential/direct purpose for SPA I can't get my hands on?
You wont have to give up back button functionality to develop a single page application. HTML5 has a history api (and there's polyfills for older browsers) which allows your to keep back button functioning properly.
The main reason (in my opinion) to go for a single page approach is the more app-like feel it gives you. For example gmail feels more like an app than a web page, and given its purpose, I think that's way it should be too. Another example might be the pixlr online image editor.
Single page approach indeed doesn't suit every purpose, but when you want a webapp to feel just that, instead of a website, then single page might be the way to go.
You mentioned direct navigation in comments, and that's totally doable if it's something that makes sense in your context. Angularjs can do that, and I'm sure pretty much every modern single page framework has a way of implementing this.

Is it possible to connect this on WordPress site ? Its new feature and I want to know is it possible and would it make sense?
Introducing new features for Website Custom Audiences
https://www.facebook.com/business/news/Multi-Product-Ads-and-Enhanced-Custom-Audiences-from-your-Website
Maybe anybody knows about that, and can help me a little bit.
I'm using WCA for most of my websites. It's good to keep your website visitors data so that you can run remarketing campaign targeting them easily in near future.
This video will show you how to install WCA script on WordPress site:

If you're not using WordPress, that's fine. Just paste the tracking pixel script inside your HTML file before </head> tag close.

We have a large web application in my office and we have a relatively large testing framework in place for the codebase (jsdriver and mocha). I'm pretty happy having a lot of the code tested (modules for web queries, controllers, etc.), but we have a lot of code that checks styling down to the pixel, which really bugs me. We have a lot of hard-coded values in the tests that make sure everything is where it's supposed to be.
For example, we have a widget A and another widget B inside of it. We then check if B is globally located properly in relation to its relative position and A's relative position. This means if we go into the styles and move something down a couple pixels, we have to go into the tests and change that hard-coded value by a couple of pixels.
This seems to create a very tight coupling of the style and tests, which I don't see a lot of value in. From an interface perspective, I see more value in testing things like is widget X visible when we move into this state. Is this a standard practice to so closely follow the pixel values? And if not, is there a better way to do it?
