Question 7

Module

Answer 7

A manageable unit of software

Question 8

Coupling

Answer 8

the linkage between modules (should be minimized)

Question 9

Cohesion

Answer 9

the internal binding within a module (should be maximized)

Question 10

Information hiding

Answer 10

restriction of information to a module (should be achieved)

Question 11

Glass box testing (white box testing)

Answer 11

• the tester is aware of the internal structure of the software (the source code);
• Pareto principle – focus on the modules where the problems seem to be;
• basis path testing – each instruction in the software is executed at least once.

Question 12

Black box testing:

Answer 12

• tests that do not rely on knowledge about the internal structure of the software (tests from the user’s point of view);
