What is test doubles in unit testing?

• Objects that make unit tests faster and simpler
• Objects used for integration testing
• Objects that provide predefined behavior
• Objects that isolate code behavior from dependencies

What is test double vs fake?

• Test doubles have working implementations, while fakes do not
• Test doubles have predefined behavior, while fakes provide working implementations
• Test doubles and fakes are interchangeable terms
• Test doubles and fakes serve different purposes in testing

What is the difference between test doubles and mocks?

• Mocks verify the behavior of the code being tested, while test doubles stand in for other objects
• Test doubles and mocks are interchangeable terms
• Test doubles focus on order of function calls, while mocks provide predefined behavior
• There is no difference between test doubles and mocks

How to test double value in Java?

Why is it called a test double?

• It simplifies testing by reducing complexity
• It replaces release-intended counterparts in testing
• It is a generic term for simplified objects used in testing
• It allows for skilled replacements of collaborator objects
