Redefine rspec-mocks method to make our sandboxing work properly. #1274

merged 1 commit into from

This is an alternate fix to #1270. It fixes the build and prevents other mock scope warnings.

I think I like it a bit better than the fix in #1270 but I'm curious on your thoughts, @xaviershay.


I like it...


First reaction was I'd prefer to fix the specs that were broken, but second reaction is that there are plenty of others that aren't "broken" but are spewing deprecations. So in that case this is the better fix.

FWIW, that was my initially reaction until I thought about it and realized the specs aren't really broken: it's just that the simplistic "are we outside an example" detection in rspec-mocks 2.99 doesn't understand the way we define and run examples from within examples in rspec-core, so it issues warnings when we are actually inside an example.
