Question 1

Which refactoring technique replaces a temporary variable with a direct call to the expression that assigned it?

Accepted Answer

Inline Temp

Answer

Inline Temp removes a temporary variable by substituting its value expression directly wherever the variable is used.

Question 2

In test-driven development (TDD), what is the correct sequence of steps?

Accepted Answer

Write test → Make it pass → Refactor

Answer

TDD follows the Red-Green-Refactor cycle: write a failing test, write minimal code to pass it, then refactor.

Question 3

Which version control strategy involves developers integrating code changes into a shared branch multiple times per day?

Accepted Answer

Continuous Integration

Answer

Continuous Integration requires developers to merge code frequently (at least daily) and run automated builds and tests on each integration.

Question 4

A code review reveals a function is 300 lines long and performs database access, business logic, and UI formatting. Which principle is violated?

Accepted Answer

Single Responsibility Principle

Answer

The Single Responsibility Principle states a class or function should have only one reason to change, but this function handles three distinct concerns.

Question 5

What does a cyclomatic complexity value of 15 in a single method indicate?

Accepted Answer

The method has 15 independent paths requiring test coverage

Answer

Cyclomatic complexity counts the number of linearly independent paths through code, indicating the minimum number of test cases needed for branch coverage.
