Morelia 0.9.2

安装

pip install morelia

快速使用指南

编写功能描述：

# calculator.featureFeature: Addition
    In order to avoid silly mistakes
    As a math idiot
    I want to be told the sum of two numbers

Scenario: Add two numbers
    Given I have powered calculator on
    When I enter "50" into the calculatorAnd I enter "70" into the calculatorAnd I press addThen the result should be "120" on the screen

创建标准python的unittest并将morelia连接到其中：

# test_acceptance.pyimportunittestfrommoreliaimportverifyclassCalculatorTestCase(unittest.TestCase):deftest_addition(self):""" Addition feature """verify('calculator.feature',self)

用你最喜欢的跑步者进行测试：unittest，nose，py.test，trial。你说出来！

$ python -m unittest -v test_acceptance  # or
$ pytest test_acceptance.py  # or
$ nosetests -v test_acceptance.py  # or
$ trial test_acceptance.py  # or
$# django/pyramid/flask/(place for your favourite test runner)

您将看到缺少哪些步骤：

现在使用您熟悉的标准测试用例来实现步骤：

# test_acceptance.pyimportunittestfrommoreliaimportverifyclassCalculatorTestCase(unittest.TestCase):deftest_addition(self):""" Addition feature """verify('calculator.feature',self)defstep_I_have_powered_calculator_on(self):r'I have powered calculator on'self.stack=[]defstep_I_enter_a_number_into_the_calculator(self,number):r'I enter "(\d+)" into the calculator'# match by regexpself.stack.append(int(number))defstep_I_press_add(self):# matched by method nameself.result=sum(self.stack)defstep_the_result_should_be_on_the_screen(self,number):r'the result should be "{number}" on the screen'# match by format-like stringself.assertEqual(int(number),self.result)

然后再次运行：

$ python -m unittest test_acceptance

Feature: Addition
    In order to avoid silly mistakes
    As a math idiot
    I want to be told the sum of two numbers
Scenario: Add two numbers
    Given I have powered calculator on                       # pass  0.000s
    When I enter "50" into the calculator                    # pass  0.000s
    And I enter "70" into the calculator                     # pass  0.000s
    And I press add                                          # pass  0.001s
    Then the result should be "120" on the screen            # pass  0.001s

注意，morelia不会浪费任何人的时间来发明一个新的测试后端 只是为了在我们的遗嘱上增加一层读写能力。步骤是微型测试用例。 您的现场客户永远不需要知道，您的单元测试和客户测试 可以分享他们的支持方法。同一个测试按钮可以运行所有TDD和BDD测试。
