Bug 1367041 - Add |mach wpt| support for Chrome, Edge and Servo, r=AutomatedTester Using the wptrun infrastructure from upstream, it is now posible to make it easy to run web-platform-tests in other browsers. The syntax used is mach wpt --product [chrome|servo|edge] [tests] This will try to use the selected product; possibly prompting to install dependencies like the WebDriver implementation. For servo if the install isn't on the PATH then --binary can be used to point to the actual location. Because manifest metadata is kept in the same directory as expectation data and we don't want to reuse Firefox expectation data for other browsers, a new products subdirectory is introduced and added to the ignore files. This will contain a subdirectory for each product into which a copy of the test manifest is placed. It may also be used to store any expectation data for the other products, in the same way as testing/web-platform/meta. MozReview-Commit-ID: 8fdCnha5t2F
