Applitools Ultrafast Grid

Massively parallel, cross-browser, multi-viewport testing.

Eliminate testing bottlenecks

Before Applitools Ultrafast Grid, functional and visual tests were run serially. Each page was checked, one by one. For each page, a screenshot was taken using the automation framework. Then the screenshot was uploaded to Applitools cloud, analyzed, and based on the result, either failed the test or kept it running.

Checking each page might take a couple of seconds. Doesn’t sound like much, but when hundreds of screenshots are multiplied across multiple viewport sizes and browsers, those seconds add up.

Applitools Ultrafast Grid eliminates this bottleneck. Your functional and visual tests go 30 to 70 times faster, running on Chrome, Firefox, Edge, and IE.

Why so fast?

Parallelization

Applitools Ultrafast Grid runs screenshot jobs in parallel by farming them out to a grid of hundreds of browsers in the cloud that generate screenshots of web pages for all the different combinations of browser types, viewport sizes, and emulated devices you request. This lets you test responsive web pages and components on a range of page widths corresponding to phones, tablets, laptops, and external monitors.

Snapshots — not screenshots

Applitools SDKs upload DOM Snapshots — not screenshots — to Applitools Ultrafast Grid. Snapshots include all resources needed to render a page (HTML, etc.) and are much smaller than screenshots, so they are uploaded much faster.

Containers — not virtual machines

Running code on multiple virtual machines in the cloud takes a lot of time and is flakey due to virtualization overhead. Applitools Ultrafast Grid uses containers to render web pages on different browsers in a much faster and more reliable way.

Snapshot caching

Applitools Ultrafast Grid does not always upload a snapshot for every page. If a page's resources didn't change, Ultrafast Grid doesn't upload them again. Since most page resources don't change from one test run to another, there's less to transfer, and upload times are measured in milliseconds.
