Removes all registered calls from the mock.

Every time a function on a mock is called, the mock registers that call and keeps it for its whole lifespan. This data is what assertion macros like ElixirMock.assert_called/1 use. The clear_calls/1 function removes all recorded calls from the mock, in effect taking it back into the state it was at definition time.

Example:

  defmodule MyTest do
    use ExUnit.Case
    require ElixirMock
    import ElixirMock
    alias ElixirMock.Mock

    test "should clear mock calls" do
      my_mock = mock_of Integer

      my_mock.to_string(1)
      assert_called my_mock.to_string(1) # passes

      :ok = Mock.clear_calls(my_mock)
      assert_called my_mock.to_string(1) # fails!
    end
  end

Gets values from context passed to mocks at definition time.

An ArgumentError is thrown if the key doesn't exist in the mock's context. See the ElixirMock.defmock_of/3 documentation for details on how to use this function.

Lists all calls made to functions defined on the mock.

Every time a function on a mock is called, the mock registers that call and keeps it for its whole lifespan. This function gets all these calls and returns them. Each function call is recorded as a tuple of the form {:function_name, [arguments]} and is added into a list of calls. Earlier calls will appear earlier in the list than those made later.

Example:

require ElixirMock
import ElixirMock
alias ElixirMock.Mock

my_mock = mock_of Integer

my_mock.to_string 1
my_mock.digits 1234

Mock.list_calls(my_mock) == [:to_string: [1], digits: [1234]]
#=> true
