Rails 模擬測試框架 FlexMock 0.9.0 發布

FlexMock是一個比較流行的針對Rails單元測試的Mock工具，

安裝方法：$ gem install flexmock

代碼示例：

 require 'test/unit'
  require 'flexmock/test_unit'

class TemperatureSampler
    def initialize(sensor)
      @sensor = sensor
    end

def average_temp
  total = (0...3).collect {
    @sensor.read_temperature
  }.inject { |i, s| i + s }
  total / 3.0
end

end
class TestTemperatureSampler < Test::Unit::TestCase
    def test_sensor_can_average_three_temperature_readings
      sensor = flexmock("temp")
      sensor.should_receive(:read_temperature).times(3).
        and_return(10, 12, 14)

  sampler = TemperatureSampler.new(sensor)
  assert_equal 12, sampler.average_temp
end

end</pre>

 FlexMock 0.9.0 增加了使用 when() 的狀態機支持，其他方面改進還包括：
 
  
 
   
It makes expectations fail as soon as the number of expected calls is exceeded. 
 
   
flexmock_teardown no longer returns a function. 
 
 
  
 
  
同時還修復了一些 bug：
 
  
 
   
fixes should_call(), allowing it on class and static methods while disallowing on class mocks. 
 
 
   
fixes Unicode argument handling issues. 
 
 
   
fixes issues with @property methods misbehaving in the debugger. 
 
 
   
fixes pytest integration and instance teardown. 
 
 
   
fixes private method handling
