質問 # 14
Your Agile team is developing a web-based system that will allow users to browse and buy online from a store's shopping catalogue. Continuous Integration has been implemented and technically it is working well, running several times per day, but each run is taking almost as much time as the team is prepared to allow. It is clear that after a few more iterations, as the number of tests needed grows with the product, it will be taking too much time.
Which of the four options contains a pair of solutions that will BOTH help to solve this problem?
a.Only include unit and component integration tests in the automated Cl runs.
b.Schedule low priority tests to be the first ones executed in each run, in order to provide rapid build verification.
c.Reduce the extent to which the automated tests go through the user interface, using technical interfaces instead.
d.Reduce the number of Cl cycles run each day.
e.Select a subset of automated tests for the daytime Cl runs, and run as many of the other tests as possible in an overnight cycle.
SELECT ONE OPTION
- A. c and e
- B. d and e
- C. a and c
- D. b and d
正解：A
解説：
The ISTQB Advanced Level Agile Technical Tester syllabus emphasizes the importance of optimizing Continuous Integration (CI) processes in Agile environments.
