<> style includes should only be used for standard library.

I suspect the reason you've used them here is because the checkdeps script
(correctly) flags these as a bad dependency.  Any code depending on base::
should be in the chromium repository and routed to blink through the blink APIs.
 We have several test support APIs in the public/ directories already
