Correct

Well Done... 🙂

Correct Answer: - i, iii & iv are true; ii & v are false

Non-functional system testing includes:

Correct

Well Done... 🙂

Incorrect

Correct Answer: - To specify which modules to combine when, and how many at once

What is the purpose of a test completion criterion?

Correct

Well Done... 🙂

Incorrect

Correct Answer: -To determine when to stop testing

Consider the following statements:

i. An incident may be closed without being fixed.

ii. Incidents may not be raised against documentation.

iii. The final stage of incident tracking is fixing.

iv. The incident record does not include information on test environments.

Correct

Well Done... 🙂

Incorrect

Correct Answer: - i is true, ii, iii and iv are false

Given the following code, which statement is true about the minimum number of test cases required for full statement and branch coverage?

Read p

Read q

IF p+q > 100 THEN

Print "Large"

ENDIF

IF p > 50 THEN

Print "p Large"

ENDIF

Correct

Well Done... 🙂

Incorrect

Correct Answer: - 1 test for statement coverage, 2 for branch coverage

Consider the following statements:

i.100% statement coverage guarantees 100% branch coverage.

ii.100% branch coverage guarantees 100% statement coverage.

iii.100% branch coverage guarantees 100% decision coverage.

iv.100% decision coverage guarantees 100% branch coverage.

v.100% statement coverage guarantees 100% decision coverage.

Correct

Well Done... 🙂

Incorrect

Correct Answer: - ii, iii & iv are True; i & v are False
