creating a double in before :all

[capoferro]

Creating a double in a before :all block triggers this error:

undefined method `double' for #RSpec::Core::ExampleGroup::Nested_1::Nested_1:0x00000001996b90

If I remove the :all, (or change to :each), the block evaluates without incident.

Rspec 2.0.1, Rails 3.

I noticed this too in a non-rails project.

Test doubles, mocks, stubs all get rolled back after each example, so before(:all) would not work even if it were made available.

I'll leave this open while I figure out where/how to best document this fact.

I have this problem as well. https://github.com/agmcleod/Copy-Process/blob/experimental/spec/copyprocess/processor_spec.rb

Line 226. However, if i take out the i method call, following it, it works fine. line 230 is for the original poster's workaround.

[agmcleod]

Sorry, that's the it method call. Comment that out and the block passing to it, tests pass, no failures.

It would be nice if RSpec could raise a developer-friendly error message instead of just NoMethodError.

[dchelimsky]

@h3h - my only concern w/ doing that is that ppl who use non-rspec frameworks would not get the same friendly messages. Seems like we'd be opening a can o' worms.

[capoferro]

I don't know enough to say whether it'd be a can of worms to add this, but I agree that an error such as "You cannot create a double in a before :all block" error would be much more helpful, as if you expect a double to work and get no method, you're more likely to think that you've spelled something wrong or missed a require than that you're just not able to make a double in that context.

+1 There should be a better error message.

I just hit this problem...
+1 There should be a better error message.

This has been resolved in RSpec 3 -- if you upgrade you'll get it.

Ah, thanks 👍
