Mobile App Design Quality Control & Assurance 4

Question 1

In mobile app QA, what does 'monkey testing' involve?

Accepted Answer

Random, automated inputs to find unexpected crashes

Answer

Monkey testing sends random, pseudo-random, or semi-random events to the app to discover crashes caused by unexpected input sequences.

Question 2

What is the key difference between 'alpha' and 'beta' testing phases?

Accepted Answer

Alpha is internal testing by the development team; beta involves external users

Answer

Alpha testing is conducted internally by the development team, while beta testing opens the app to a selected group of external users.

Question 3

A QA team uses a 'test pyramid' strategy. What does the pyramid suggest about unit tests vs. UI tests?

Accepted Answer

More unit tests at the base, fewer slow UI tests at the top

Answer

The test pyramid advocates for a large base of fast, cheap unit tests and fewer slow, expensive UI/end-to-end tests at the top.

Question 4

Which scenario BEST describes an 'intermittent bug' in mobile QA?

Accepted Answer

A bug that reproduces inconsistently and is hard to isolate

Answer

Intermittent bugs occur unpredictably, often due to race conditions, timing issues, or environment-dependent factors, making them difficult to reproduce and fix.

Question 5

What is the purpose of a 'bug severity' classification in QA defect tracking?

Accepted Answer

To indicate the impact of the bug on app functionality or users

Answer

Bug severity classifies the functional impact of a defect (e.g., critical crash vs. minor typo) to help teams prioritize fixes.
