What are some examples of mock testing in Python?

Mock testing in Python is used to simulate objects in your tests. For example, you can use the unittest.mock library to create mock objects.

Can you show me a simple code example?

Sure! Here's a basic example:

from unittest.mock import Mock

# Create a mock object
mock_obj = Mock()

# Set a return value
mock_obj.some_method.return_value = 'Hello, World!'

# Call the method
result = mock_obj.some_method()
print(result)  # Output: Hello, World!

What is the purpose of using mock objects?

Mock objects help isolate the code being tested by replacing dependencies, allowing you to test components in isolation.

Are there any libraries specifically for mock testing?

Yes, the unittest.mock library is built into Python's standard library, and there are also third-party libraries like pytest-mock.
