15.Mocking Introduction

What is mocking in Java?

• Simulating behavior in tests.
• Generating fake data.
• Modifying runtime behavior.
• Testing object interactions.

What is the concept of mocking?

• Creating fake objects.
• Generating test data.
• Simulating network communication.
• Automating test cases.

When to use mocking Java?

• Testing dependencies.
• Generating reports.
• Optimizing code.
• Deploying to production.

What is mocking in programming?

• Simulating behavior for testing.
• Intentionally causing errors.
• Generating test cases.
• Manipulating data.

What is mocking and examples?

• Creating fake objects, e.g., mocking a database.
• Modifying production code for debugging.
• Generating random test cases.
• Simulating user interactions.

What is mock object in Java with example?

• Simulated object with predefined behavior, e.g., mocking a database connection.
• Fully functional object for production code.
• Placeholder for null values.
• Object created using new.

Why is mocking useful?

• Enables isolated testing.
• Speeds up development.
• Improves performance.
• Replaces unit tests.

Why is mocking important?

• Identifies bugs and issues.
• Improves code readability.
• Ensures integration with external systems.
• Enhances code maintainability.

What is the need of mocking?

• Isolate dependencies for focused testing.
• Generate test data quickly.
• Improve code performance.
• Simulate real-world scenarios.

What is mock annotation in Java?

• Marks a method as a mock.
• Defines a fake object.
• Indicates a mock object for testing.
• Specifies a placeholder value.
