This Python module implements a Category class representing a category with a name, description, and an activation status.
- A category must have a name.
- The name of the category must have less than 256 characters.
- When a category is created, it must be assigned a UUID as its identifier.
- A category is created with default values if no additional values are provided.
- The default value for the is_active attribute is True.
- The string representation of a category follows the format:
<name> - <description> (<is_active>). The representation of a category (__repr__method) follows the format:<Category <name> <id>>.
The following test cases are implemented to ensure the correctness of the Category class:
-
Test Name is Required
- Description: Ensure that an error is raised when trying to create a category without providing a name.
- Expected Result: TypeError with message "missing 1 required positional argument: 'name'".
-
Test Name Length Limit
- Description: Ensure that an error is raised when the name provided for a category exceeds 255 characters.
- Expected Result: ValueError with message "name must have less than 256 characters".
-
Test Category Creation with UUID
- Description: Ensure that a category is created with a UUID as its identifier.
- Expected Result: The id attribute of the created category is of type UUID.
-
Test Default Category Creation
- Description: Ensure that a category is created with default values when no additional values are provided.
- Expected Result: The category has an empty description and is active.
-
Test Category Creation with Provided Values
- Description: Ensure that a category is created with the provided values.
- Expected Result: The category has the provided attributes.
-
Test String Representation
- Description: Ensure that the string representation of a category is correct.
- Expected Result: The string representation matches the expected format.
-
Test Representation Method (repr)
- Description: Ensure that the representation method returns the correct string.
- Expected Result: The representation string matches the expected format.
