When is it time to integrate the code?

A. Before each release
B. At the end of the project
C. Frequently, during the Sprint
D. At the end of each Sprint

Correct Answer: C

If there are multiple Developers working on the Sprint Backlog the code has to be integrated as often as possible. Not doing this often results in a lot of bugs, because the complexity increases. This is why Agile working promotes continuous integration.
