iilyak opened a new pull request #2121: Add Mock library for testing
URL: https://github.com/apache/couchdb/pull/2121
 
 
   ## Overview
   
   Add mocking library to use from ExUnit based unit tests.
   
   ## Testing recommendations
   
   1. Create `src/couch/test/exunit/mocking_test.exs` file with the following 
content
     ```
     defmodule Couch.Test.Mocking do
       @moduledoc false
       use Couch.Test.ExUnit.Case
   
       alias Couch.Test.Setup
   
       import Mock
   
       def with_setup(context, setup) do
         setup =
           setup
           |> Setup.run()
   
         {context, setup}
       end
   
       describe "Testing mocking machinery" do
         @describetag setup: &__MODULE__.with_setup/2
         test "that we can mock CouchDB modules", _ctx do
           with_mock :fabric, all_dbs: fn -> :foo end do
             assert :fabric.all_dbs() == :foo, "Expected to get ':foo'"
           end
         end
       end
     end
     ```
   2. Run test suite `make exunit tests=src/couch/test/exunit/mocking_test.exs`
