Via this rspec-rails issue, I discovered this issue where rails-controller-testing is breaking URL helpers in view tests.
This was fixed in rails-controller-testing v1.0.2 but unfortunately we can't use this in the rails42.gemfile because the v1.0.2 version depends on ActionView / ActionPack at v5.x.
Removing the rails-controller-testing gem and rewriting the two affected specs which used assert_render_template fixed the failures on my machine.
