ITPEC FE Morning October 2023 Question 49
ITPEC FE Morning October 2023 — Question 49 of 80
Extreme Programming (XP) practices — identify core XP methodology characteristics.
XP is an Agile methodology built around short iterations and continuous feedback. Key practices include:
- •Test-Driven Development (TDD) — tests are written before code
- •Continuous Integration — code integration and testing are repeated continuously
- •Refactoring — code is improved constantly, not deferred
- •Pair Programming — two developers work together at one workstation
- •Customer involvement — the customer writes acceptance tests, not unit tests
Why not others:
- (a) contradicts TDD — tests come before code, not after integration
- (c) contradicts refactoring — code is refactored immediately, not delayed
- (d) developers write unit tests; the customer specifies acceptance criteria
Key rule: XP emphasizes continuous integration, TDD (test-first), and constant refactoring as core engineering practices.
