The HTML for the failed page, and a screenshot image (when using capybara-webkit, Selenium or poltergeist) is saved into $APPLICATION_ROOT/tmp/capybara. Having screenshots readily available for each test failure is incredibly helpful when trying to quickly diagnose a problem in your failing steps. You can view the source code, and have a screen shot of the page (when applicable), at the time of each failure.

SlimerJS is useful to do functional tests, page automation, network monitoring, screen capture, web scraping etc. It provides support to load a web page and inspect its content. It can act on a web page like a user: click on links, fill in form fields etc. You can then inspect the results, to test them or to retrieve them. It helps to take screenshots of a web page.

It aims to be a lightweight command line tool for either helping out on day-to-day life operations or complicated detail-centric issues. Originally it was designed to record/screenshot terminal windows but it can be tweaked easily for other purposes with command line arguments, environment variables, or a configuration file. menyoki requires a window system implementation of the supported platform for record and capture actions. Other features are expected to work normally since they don't require a window system running (or grabbing a window to operate on). For example, despite the macOS is not listed as a supported platform, menyoki still can perform image operations such as edit and analyze if it's compiled on macOS.

The Prerender server listens for an http request, takes the URL and loads it in Headless Chrome, waits for the page to finish loading by waiting for the network to be idle, and then returns your content. The Prerender server can be used in conjunction with our Prerender.io middleware in order to serve the prerendered HTML of your javascript website to search engines (Google, Bing, etc) and social networks (Facebook, Twitter, etc) for SEO. We run the Prerender server at scale for SEO needs at https://prerender.io/.
When compressing JPEG images, the same compression level is used on the entire image. However, most JPEG images contain homogeneous and heterogeneous areas, which are varyingly well-suited for compression. Compressing heterogeneous areas in JPEGs to reduce filesize causes compression artefacts due to the lossy nature of JPEG compression. This script adaptively alters the compression level for areas within JPEGs (per-block) to achieve optimized file size while maintaining a decent visual quality. This script achieves a significantly reduced file size compared to standard tools such as cjpeg while maintaining good visual quality, as can be measured via SSIM. This is good news for the Web Performance and thus Web Developer community to achieve a great user experience on websites.
CasperJS is a navigation scripting & testing utility for PhantomJS and SlimerJS (still experimental). It eases the process of defining a full navigation scenario and provides useful high-level functions, methods & syntactic sugar for doing common tasks such as Filling forms, Clicking links, Capturing screenshots of a page, Downloading resources, even binary ones, Writing functional test suites, exporting results as JUnit XML (xUnit) and lot more.
