Quizz Day 2 Python Testing Short Version

What is a unit test?

• A tool to deploy code
• Code verifying correctness of a small, isolated unit
• A function that compiles code
• A system log

Unit tests help detect bugs

• Only in production
• Early during development
• During deployment
• Never

Unit tests enable refactoring because

• They guarantee data privacy
• They detect regressions automatically
• They prevent imports
• They reduce file size

Unit tests serve as

• Documentation and examples
• Logging files
• Compilers
• Debuggers

Writing testable code improves

• Design and architecture
• Speed only
• File system
• None

pytest originated from
