What is an integration test? (choose the best answer)

• A test of the user interface.
• A test of a Single unit of functionality.
• A test that runs during a Continuous Integration build.
• A test of multiple units of functionality.

What is a unit test? (choose the best answer)

• A way to ensure product code satisfies the user requirements.
• A technique for ensuring that units of co-dependent systems integrate correctly.
• A test that isolates and verifies individual units of functionality
• A test that ensures a specific method integrates properly with the code calling it.

What is a mock object? (choose the best answer)

• A test object that mimics the behavior of a dependency in the system under test.
• A mock helps you create a build script.
• Mocks, stubs, dummies, fakes, and shims are all the same.
• A mock is a way to initialize the database for testing.

What is a merge in a version control system? (choose the best answer)

• Combining two or more versions of code into a single codebase.

What are two ways Developers can ensure a good application architecture? (choose the best two answers)

• The Developers have a set of guiding arctlitecture principtes that are understood and followed when writing Code.

• The Scrum Team assigns someone to the role of software architect to provide architectural oversight.
• The Developers at Sprint O create intrastructure that Will be needed later.
• The Developers focus only on adding tunctionality. The architecture will take care of itself as the Developers add tunctionality.
• Architecture is an ongoing discussion by Developers, focusing on implementing current Sprint Backlog items.

What are two reasons to use mock objects in unit tests? (choose the best two answers)

• The behavior of a given Object can be emulated to the system under test.
• They are machine-generated and eliminate the need to write code by hand.
• Isolating a particular system component for controlled testing.
• TDD is impossible without them.
• To decrease cyclomatic complexity.
