ITPEC FE Morning October 2023 Question 49

Integration of the code and testing are continuously repeated — continuous integration is one of the core XP practices.

Extreme Programming works in short iterations with fast feedback. Its engineering practices include:

• •Test-driven development: developers write unit tests before the code
• •Continuous integration: code is integrated and all tests are run many times a day
• •Refactoring: code is improved whenever needed, kept passing by the tests
• •Pair programming, small releases, and an on-site customer who writes acceptance tests

Answer (b)

Why not others:

• •(a) — XP writes tests first (test-first), not after the code has been created and integrated
• •(c) — XP refactors continuously, as soon as a design can be improved, not deferred to the next iteration
• •(d) — unit tests are written by the programmers; the customer is responsible for acceptance tests

Key rule: In XP, tests come before code, integration happens continuously, and refactoring is constant; the customer owns acceptance tests, the developers own unit tests.
