The code you provided is not a class but a series of step definitions for a Behavior-Driven Development (BDD) test using the Behave framework in Python. These steps correspond to a specific scenario written in Gherkin language (Given, When, Then format).
These step definitions describe how to interact with an AssetManager class and an InMemoryAssetRepository class. They're meant to test the creation of assets and the calculation of the total cost of all assets.
Let's go through each step:
@given('the Asset Manager is running'): This sets up the initial state for the test. It initializes the AssetManager with an InMemoryAssetRepository (which presumably stores assets in memory during the execution of the test) and a mocked AssetLocationMediator.
@given('the InMemoryAssetRepository is initialized') and @given('the AssetLocationMediator is mocked'): These steps appear to be placeholders, as they don't execute any actions.
@when('I create an asset with a cost of ${cost}') and @when('I create another asset with a cost of ${cost}'): These steps create Asset instances with the given cost and add them to the AssetManager.
@then('the total cost of all assets should be ${total_cost}'): This step retrieves all the assets from the AssetManager, calculates the total cost, and checks that it matches the expected total cost.
This sequence of steps allows the user to test the process of creating assets and validating the total cost of all assets in the AssetManager.
