Calling let(:something) from before blocks?

Testing RSpec
1

Hello!

I find myself repeating the same let(:something) statements over and
over again in different view examples. Therefore, I wonder if it’s
possible to define these globally in the spec_helper.rb file. I came up
with the following approach:

spec/spec_helper.rb

RSpec.configure do |config|

…

config.before(:each, :type => :view) do
let(:something) { “available for all view examples” }
end

…

end

However, this doesn’t work because let isn’t defined in that context:

Failure/Error: Unable to find matching line from backtrace
undefined method `let’ for
#RSpec::Core::ExampleGroup::Nested_1:0x105569298

Some kind of workaround to make this work would be really nice. Is this
usage of let supported at all?

Thx & best regards,
Christoph

PS: I’m using rspec 2.0.1, rails 3.0.1 and ruby 1.8.7.

Not as of yet. Not sure if I’d like to add it or not, but please file a
feature request: Issues · rspec/rspec-core · GitHub.
