Example

1. After installing behave, we can create a file called install.feature in the features directory with the following content:

   Feature: showing off behave
   
     Scenario: run a simple test
        Given we have behave installed
         When we implement a test
         Then behave will test it for us!

2. Next, we create the file install.py in the directory features/steps:

   from behave import *
   
   
   @given("we have behave installed")
   def step_impl(context):
       pass
   
   
   @when("we implement a test")
   def step_impl(context):
       assert True is not False
   
   
   @then("behave will test it for us")
   def step_impl(context):
       assert context.failed is False

3. Call behave

   $ behave
   USING RUNNER: behave.runner:Runner
   Feature: showing off behave # features/install.feature:1
   
     Scenario: run a simple test        # features/install.feature:3
       Given we have behave installed   # features/steps/install.py:3 0.000s
       When we implement a test         # features/steps/install.py:7 0.000s
       Then behave will test it for us  # features/steps/install.py:11 0.000s
