What is PhantomJS and what are its top alternatives?
Top Alternatives to PhantomJS
- Selenium
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well. ...
- Electron
With Electron, creating a desktop application for your company or idea is easy. Initially developed for GitHub's Atom editor, Electron has since been used to create applications by companies like Microsoft, Facebook, Slack, and Docker. The Electron framework lets you write cross-platform desktop applications using JavaScript, HTML and CSS. It is based on io.js and Chromium and is used in the Atom editor. ...
- Protractor
Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would. ...
- wkhtmltopdf
wkhtmltopdf and wkhtmltoimage are command line tools to render HTML into PDF and various image formats using the QT Webkit rendering engine. These run entirely "headless" and do not require a display or display service. ...
- SlimerJS
It allows you to manipulate a web page with an external Javascript script: opening a webpage, clicking on links, modifying the content... It is useful to do functional tests, page automation, network monitoring, screen capture etc. ...
- Puppeteer
Puppeteer is a Node library which provides a high-level API to control headless Chrome over the DevTools Protocol. It can also be configured to use full (non-headless) Chrome. ...
- CasperJS
CasperJS is a browser navigation scripting & testing utility written in Javascript for PhantomJS or SlimerJS. ...
- Node.js
Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. ...

When you think about test automation, it’s crucial to make it everyone’s responsibility (not just QA Engineers'). We started with Selenium and Java, but with our platform revolving around Ruby, Elixir and JavaScript, QA Engineers were left alone to automate tests. Cypress was the answer, as we could switch to JS and simply involve more people from day one. There's a downside too, as it meant testing on Chrome only, but that was "good enough" for us + if really needed we can always cover some specific cases in a different way.
For our digital QA organization to support a complex hybrid monolith/microservice architecture, our team took on the lofty goal of building out a commonized UI test automation framework. One of the primary requisites included a technical minimalist threshold such that an engineer or analyst with fundamental knowledge of JavaScript could automate their tests with greater ease. Just to list a few: - Nightwatchjs - Selenium - Cucumber - GitHub - Go.CD - Docker - ExpressJS - React - PostgreSQL
With this structure, we're able to combine the automation efforts of each team member into a centralized repository while also providing new relevant metrics to business owners.

The Slack desktop app was originally written us the MacGap framework, which used Apple’s WebView to host web content inside of a native app frame. As this approach continued to present product limitations, Slack decided to migrate the desktop app to Electron. Electron is a platform that combines the rendering engine from Chromium and the Node.js runtime and module system. The desktop app is written as a modern ES6 + async/await React application.
For the desktop app, Slack takes a hybrid approach, wherein some of the assets ship as part of the app, but most of their assets and code are loaded remotely.
Slack's new desktop application was launched for macOS. It was built using Electron for a faster, frameless look with a host of background improvements for a superior Slack experience. Instead of adopting a complete-in-box approach taken by other apps, Slack prefers a hybrid approach where some of the assets are loaded as part of the app, while others are made available remotely. Slack's original desktop app was written using the MacGap v1 framework using WebView to host web content within the native app frame. But it was difficult to upgrade with new features only available to Apple's WKWebView and moving to this view called for a total application rewrite.
Electron brings together Chromium's rendering engine with the Node.js runtime and module system. The new desktop app is now based on an ES6 + async/await React application is currently being moved gradually to TypeScript. Electron functions on Chromium's multi-process model, with each Slack team signed into a separate process and memory space. It also helps prevent remote content to directly access desktop features using a feature called WebView Element which creates a fresh Chromium renderer process and assigns rendering of content for its hosting renderer. Additional security can be ensured by preventing Node.js modules from leaking into the API surface and watching out for APIs with file paths. Communication between processes on Electron is carried out via electron-remote, a pared-down, zippy version of Electron's remote module, which makes implementing the web apps UI much easier.

Currently, we are using Protractor in our project. Since Protractor isn't updated anymore, we are looking for a new tool. The strongest suggestions are WebdriverIO or Puppeteer. Please help me figure out what tool would make the transition fastest and easiest. Please note that Protractor uses its own locator system, and we want the switch to be as simple as possible. Thank you!
Protractor or Cypress for ionic-angular?
We have a huge ionic-angular app with almost 100 pages and 10+ injectables. There are no tests written yet. Before we start, we need some suggestions about the framework. Would you suggest Cypress or Angular's Protractor with Jasmine / Karma for a heavy ionic app with Angular?

I work in a company building web apps with AngularJS. I started using Selenium for tests automation, as I am more familiar with Python. However, I found some difficulties, like the impossibility of using IDs and fixed lists of classes, ending up with using xpaths most, which unfortunately could change with fixes and modifications in the code.
So, I started using Puppeteer, but I am still learning. It seems easier to find elements on the webpage, even if the creation and managing of arrays of elements seem to be a little bit more complicated than in Selenium, but it could be also due to my poor knowledge of JavaScript.
Any comments on this comparison and also on comparisons with similar tools are welcome! :)

We use CasperJS because we adopted it back in 2013 for JavaScript frontend testing. It was a really nice system back then compared to what else was out there; you had PhantomJS as a programmable browser that actually rendered CSS and everything, it was really fast (speed is a big downside of e.g. Selenium), and it was possible to make non-flaky frontend integration tests with it.
I wouldn't recommend it today, because PhantomJS is a basically dead project, and as a result, so is CasperJS. I expect we'll migrate to something else. We haven't in large part because 95% of our new tests are written with a simple Node.js-based unit testing framework we use that run 35K lines of unit tests covering most of our JS codebase in 3.6 seconds. And for the things where we want an integration test, CasperJS does work, and I think there's a good chance that waiting another year or two will result in our being able to switch to a much better option than what we'd get if we migrated now.

When I joined NYT there was already broad dissatisfaction with the LAMP (Linux Apache HTTP Server MySQL PHP) Stack and the front end framework, in particular. So, I wasn't passing judgment on it. I mean, LAMP's fine, you can do good work in LAMP. It's a little dated at this point, but it's not ... I didn't want to rip it out for its own sake, but everyone else was like, "We don't like this, it's really inflexible." And I remember from being outside the company when that was called MIT FIVE when it had launched. And been observing it from the outside, and I was like, you guys took so long to do that and you did it so carefully, and yet you're not happy with your decisions. Why is that? That was more the impetus. If we're going to do this again, how are we going to do it in a way that we're gonna get a better result?
So we're moving quickly away from LAMP, I would say. So, right now, the new front end is React based and using Apollo. And we've been in a long, protracted, gradual rollout of the core experiences.
React is now talking to GraphQL as a primary API. There's a Node.js back end, to the front end, which is mainly for server-side rendering, as well.
Behind there, the main repository for the GraphQL server is a big table repository, that we call Bodega because it's a convenience store. And that reads off of a Kafka pipeline.
How Uber developed the open source, end-to-end distributed tracing Jaeger , now a CNCF project:
Distributed tracing is quickly becoming a must-have component in the tools that organizations use to monitor their complex, microservice-based architectures. At Uber, our open source distributed tracing system Jaeger saw large-scale internal adoption throughout 2016, integrated into hundreds of microservices and now recording thousands of traces every second.
Here is the story of how we got here, from investigating off-the-shelf solutions like Zipkin, to why we switched from pull to push architecture, and how distributed tracing will continue to evolve:
