Add Action in feature file

[VectorZYJ]

As a QA engineer
I need to write Gherkin features using the behave tool to test the 'Purchase' operation of the API
So that I can ensure the API correctly handles creation requests and responses

Details and Assumptions

• The Purchase feature should be written in a .feature file using Gherkin syntax.
• The feature should be supported by a steps.py file that defines the steps.
• The behave tool will be used to execute the BDD test.
• The Purchase scenario will include API request, response validation, and error handling cases.

Acceptance Criteria

Given a running API service with the ability to handle 'Purchase' operations
When I write a feature file with a scenario for creating a resource
And I implement the steps in a `steps.py` file
Then I can execute the BDD test to verify that the 'Purchase' operation behaves as expected
