Rails 单元测试，FlexMock 0.9.4 发布

   <p><a href="/misc/goto?guid=4958197824004491022" target="_blank">FlexMock</a>是一个比较流行的针对Rails单元测试的Mock工具，</p>    <p>安装方法：$ gem install flexmock<br /> </p>    <p>FlexMock 0.9.4 发布，该版本主要改进内容包括：</p>    <p>1. This release adds support for stubbing return values on getter properties and non-callable attributes. <br /> 2. It also adds custom matcher object support to with_args(), stricter<span class="truncate_more"> function signature checks, support for chained attributes, and iter support to Mock objects. <br /> 3. should_call() is fixed to work with class mocks, and_return() is fixed to return None by default, and partial mocks created using the func=return_value style will now use replace_with() instead of should_receive() for callable values. <br /> 4. As of this release, flexmock is also tested as working on PyPy and Jython<br /> <br /> </span></p>    <p></p>    <p>代码示例：</p>   <pre class="brush:ruby; toolbar: true; auto-links: false;">  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>    <p></p>
