It causes a new set of tests to run. There's a dozen or so reftests in the
tree right now. When they fail, you'll see a pixel diff the same way you
would with pixel tests, but we don't compare the rendertrees, so there's
never a text diff. In theory, none of the current reftests have any
platform specific bits, so they should pass for all ports.
Currently, the thing that determines whether something is a reftest is
whether there is a -expected.html file. So, foo/bar/myreftest.html will
have a foo/bar/myreftest-expected.html that should render the same as
As we import reftest suites, we may add other ways of making things
reftests (e.g. putting them in a reftests folder?). See
