NOTE: BrowserSwarm is a partnership between Microsoft, Sauce Labs, and appendTo — cloud-driven in its nature, BrowserSwarm is designed to help save time (and precious server resources) when setting-up multiple browser or device testing environments.
But, asks Microsoft, what if you're a startup building a new framework?
"Testing is probably the last (but necessary) thing you want to do," writes Justin Garrett of Microsoft. "So — just like the free testing tools and resources on modern.IE that help developers of public-facing sites or line-of-business web apps — we are partnering on BrowserSwarm to help the developers that build stuff for developers — the framework authors. We want to help reduce the time spent testing frameworks (and the sites they service) so that developers have more time to innovate on the Web."
