Behave 步骤中的步骤

我们可以用一个宏步骤代替一个场景中的多个步骤。这有助于我们在步骤定义文件中不重复相同的代码。BDD框架有能力从步骤定义中调用多个步骤。

具有类似步骤的特征文件

具有类似步骤的特征文件如下所示

Feature − Payment Module
   Scenario − Verify message after payment
      Given User is on payment screen
      When User enters payment details
      And User completes payment
      Then User should get success message
   Scenario − Verify new users can process payment
      Given User keys in payment info and submits
      Then success message should get displayed

在特征文件中，我们有两个具有类似步骤的Scenario。在Behave中，我们可以在一个步骤中执行一个以上的步骤。这可以在步骤实现文件中的context.execute_steps方法的帮助下完成。

相应的步骤实现文件

上述特征文件的对应步骤实现文件如下

from behave import *
@given('User is on payment screen')
def is_on_payment_screen(context):
   print('User is on payment screen')
@when('User enters payment details')
def enters_payment_details(context):
   print('When User enters payment details')
@when('User completes payment')
def completes_payment(context):
   print('When User completes payment')
@then('User should get success message')
def get_success_message(context):
   print('Then User should get success message')
   @given('User keys in payment info and submits')
def payment_info_and_submits(context):
#passing steps within steps with context.execute_steps
   context.execute_steps(u"""
      Given User is on payment screen
      When User enters payment details
      And User completes payment
      """)
@then('success message should get displayed')
def success_message(context):
   print('Then success message should get displayed')
