質問 1：
Given the following pseudocode:
Program tax check
Integer: tax_rate
real: tax%
BEGIN
tax% := 0
GET (tax_rate)
WHILE tax_rate > 0 loop
IF tax_rate > 3 THEN
tax_rate := 3
ENDIF
tax% := tax% + (tax_rate / 10)
tax_rate := tax_rate - 1
ENDLOOP
IF tax% > 0.6 THEN
print ("tax rate is high")
ELSEIF tax% < 0.1 THEN
print ("tax rate is zero")
ELSE
print ("tax rate is low")
ENDIF
END tax check

A. Unreachable code at line 17
B. Unreachable code at line 15
C. No unreachable code
D. Infinite loop from line 7 to line 13

質問 2：
A review of the following pseudo code is to be performed using a checklist:
Module Vowel Counter
Message: array of Characters
M, N: Integer
ACount, ECount, ICount, OCount, UCount: Integer
BEGIN
I=1
Read Nextchar
While Nextchar <> 'S'
DO
Message (I) = Nextchar
I = I+1
Read Nextchar
ENDWHILE
FOR M = 1 To I
DO
Print (Message(M))
IF Message (M) = 'E'
THEN
ECount = ECount + 1
ELSE
IF Message (M) = 'A'
THEN
ACount = ACount + 1
ELSE
IF Message (M) = 'I'
THEN
ICount = ICount + 1
ELSE
IF Message (M) = 'O'
THEN
OCount = OCount + 1
ELSE
IF Message (M) = 'U'
THEN
UCount = UCount + 1
ENDIF
ENDIF
ENDIF
ENDIF
ENDIF
ENDFOR
Print ('Message contains ' ACount + ECount + ICount + OCount + UCount ' vowels') END Which of the following checklist items would find code errors in this scenario?
A) Are all variables properly declared?
B) Are all loops, branches, and logic constructs complete, correct, and properly nested?
C) Are all cases covered in an IF-ELSEIF, including ELSE or DEFAULT clauses?
D) Are loop termination conditions obvious and invariably achievable?
E) Are there any redundant or unused variables?
A. c and d
B. a and d
C. a and e
D. b and c

質問 3：
Which statement about test automation being applied to a reactive test approach, is CORRECT' SELECT ONE OPTION
A. Automation of test execution in exploratory test sessions can lead to increased efficiency and wider coverage of user stories
B. For projects that must comply with externally defined regulations, the automated tests and their results must be traceable back to requirements
C. An increase in automated test coverage can lead to a greater degree of exploratory testing addressing high risk areas
D. BDD can be used within a reactive testing approach by producing automated tests in parallel with the implementation of the user story
