shoulda-matchers not working with spring

[ghost]

Not sure if this is a spring issue or a shoulda-matchers issue.

On Rails 4.1, spring 1.1.2 and shoulda-matchers 2.6.0 none of the matchers from shoulda-matchers seem to work:

     Failure/Error: it { should validate_presence_of(:first_name) }
     NoMethodError:
       undefined method `validate_presence_of' for #<RSpec::Core::ExampleGroup::Nested_1:0x007fcafe53a018>

Here is an example app with spring setup https://github.com/Soliah/foo

Running bundle exec rspec spec works fine, but using the spring binstub for rspec bin/rspec causes the undefined method error.

I have this same issue. There is a workaround by requiring shoulda-matchers a little later. So in your Gemfile do:

gem 'shoulda-matchers', require: false

...and then in spec/spec_helper require it manually:

require 'shoulda-matchers'

Since Rails 4.1 ships with Spring by default, it would be nice to note this in the README.

Thanks for the report.

Yeah, shoulda-matchers needs to be loaded after RSpec is loaded, so that it can detect it and inject itself into the appropriate example groups.

This should automatically happen when Bundler requires your gems, because shoulda-matchers is loaded after rspec-rails. However, requiring rspec-rails, it turns out, doesn't actually load all of RSpec until you require 'rspec/rails' in your spec_helper. By that point, shoulda-matchers is already loaded so it doesn't auto-insert itself.

Why has this always worked before, then? Because the rspec executable loads all of RSpec, so it's there before your spec_helper is even loaded.

Why doesn't this now work? Because Spring flips it around: spec_helper (and your Gemfile) are loaded before the rspec executable is run.

Closing in favor of #490.
