View

In TDD, what is the goal of writing a test that fails initially?

To identify errors in the code
To ensure the test suite is working correctly
To provide a baseline for future tests
To force the developer to implement the code

When refactoring code in TDD, what should you ensure?

Tests are ignored during refactoring
Code behavior does not change
Tests are modified to reflect new functionality
Refactoring should happen after deployment

What is a “red-green-refactor” cycle in TDD?

The process of checking performance, optimization, and testing
A feedback loop of writing failing tests, passing tests, and improving code
A coding convention for error handling
A strategy for handling errors in JavaScript code

Which of the following is true about tests in TDD?

They should only test simple functions
They should be written for all new features before the code is written
They should be written after the code is complete
They should only test public methods

Why is code modularity important in TDD?

It reduces the need for documentation
It helps test isolated pieces of functionality
It increases development speed
It eliminates the need for unit testing

In TDD, why is test coverage not always the best indicator of code quality?

Test coverage can be faked
Test coverage only indicates the quantity of tests, not the quality
Higher coverage reduces code reliability
Coverage is not important in TDD

Which of the following scenarios is an anti-pattern in TDD?

Refactoring before writing tests
Writing tests for all edge cases
Writing code without writing a test first
Focusing only on unit tests

What is the benefit of continuous testing in TDD?

It allows developers to skip tests
It ensures that tests are only run once
It enables constant feedback on the state of the codebase
It automatically optimizes the code

What should you do when a test passes in TDD?

Write more code
Refactor the code if needed
Remove the test
Skip to the next feature

Which of the following is a benefit of refactoring code in the TDD process?

It allows for adding unnecessary features
It increases the complexity of the code
It improves the code's structure and readability
It skips testing altogether
