Why don't you use let:
describe MyClass do # Will set subject to an instance
of MyClass
context '#parse_input' do
let(:input) { subject.parse_input } # calling input in your specs will
now return the result of parse_input
it 'is a hash' do
input.should be_a(Hash) # This evaluates let(:input)
end
end
end
Hope that helps.
