CTAL-TTA Exam Dumps : Certified Tester Advanced Level Technical Test Analyst

When users complain about issues with links on a website, the most appropriate test tool to identify the causes of these failures is a hyperlink tool (answer B). Hyperlink tools are specifically designed to check the validity of links on web pages. They can automatically identify broken or dead links, which is essential for maintaining the quality and user experience of a website. Review tools, static analysis tools, and dynamic analysis tools do not primarily focus on hyperlink verification.

Story Mapping is an effective requirements engineering technique used in Agile environments to provide a visual representation of the system. It helps in understanding the 'overall' story and functional flow by mapping user stories along a timeline or process steps, laying them out in a two-dimensional structure that represents the product backlog. This technique is particularly useful for visualizing the scope of large features or entire systems, making it easier to plan releases and improve understanding among the team .

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

Explanation of Control Flow:

Initialization:

tax% := 0

Get Tax Rate:

GET (tax_rate)

While Loop:

Loop runs while tax_rate > 0.

Inside the loop:

If tax_rate > 3, set tax_rate to 3.

Update tax% by adding tax_rate / 10.

Decrement tax_rate by 1.

Post-Loop Condition Checks:

After the loop, check the value of tax%:

If tax% > 0.6, print "tax rate is high".

Else if tax% < 0.1, print "tax rate is zero".

Otherwise, print "tax rate is low".

Unreachable Code Analysis:

The ELSEIF tax% < 0.1 THEN condition (line 17) is unreachable.

In the loop, tax% is incremented by a minimum of 0.1 each time tax_rate is greater than 0.

Therefore, tax% cannot be less than 0.1 after the loop.

Conclusion:

Line 17 (ELSEIF tax% < 0.1 THEN) will never be true given the logic of the loop.
