BTW - another approach is to write a matcher and use the one-liner syntax:
RSpec::Matchers.define :check_minimum_protected_api_params do |url|
match do |_|
get url
# .... return true/false for pass/fail
end
end
Now you can say:
it { should check_minimum_protected_api_params("/api/v1/originator/hello") }
Cheers,
David
