ruby - RSpec testing module methods/ -

-

i have next modules.

module   module b           def self.method_b(value)       #code     end   end  end

and 

module   module c     def self.method_c(value)        a::b.method_b(value)     end   end end

how test these module? how create stub self.method_b?

spec_helper.rb

rspec.configure |config|  config.mock_with :mocha end

thanks.

you have switched out built-in rspec mocking library mocha. has different api. try:

a::b.stubs(:method_b).returns('value')
