Deep study of this set of 80 questions shall be of great help in getting success in ISTQB CTAL Advanced Level Test Analyst & Technical Test Analyst Exam. All these questions are based upon ISTQB Certified Tester Advanced Level Syllabus V 2007.

Set of 10 Questions (Q. 41 to 50)

Correct Answers of earlier Q. 31 to 40 are at the end of this page:

Q. 41: A software company developed a software application for a Life Insurance Company. The testers of the software company were given the release to test.

The software application calculates the annual life insurance cost based on customers’ age. Life insurance cost is as follows per year;

# Age 18

or less: US $ 300# Age over 18 or less than 70: US $ 500

# Person has to be at least 1 year old to purchase insurance

If a customer enters any other age, the software prints an error message. The Application accepts only positive integer values (no decimals).

How many test cases at minimum can you derive using both Boundary Value analysis and Equivalence partitioning to test the life insurance application?

A. 9
B. 10
C. 6
D. 3

Explanation in favor of the correct Answer:

Using Equivalence Partitioning (EP), (since the question does not mention valid/invalid partitions), we have to consider both.

EP tests: 0, 2, 20, 75 (two from valid partition and two from invalid partition.)

BV tests: 0, 1,2, 17,18,19, 69, 70, 71

Now let’s see the unique number of tests that we can get: 0, 1,2,17,18,19,69,70,71

So the total number of tests are: 9

Why did we ignore 20 and 75 ?

Because 20 and 19 both in the same valid partition and 19 is in the boundary. Therefore, we picked 19.

75 and 71 both in the same invalid partition and 71 is in the boundary. Therefore, we picked 71.

Q. 46: Use the following code;

x=1
y=2
z=3
If (x = = 2)
{
print “Hi There !”;
}
else
{
print “Good bye”;
}
z=x + y;
if (z ==4)

How many test cases, at minimum, are required for statement coverage?

A. 4
B. 2
C. 3
D. 8

Explanation in favor of the correct Answer:

In this case, we need to find how many test cases are required to cover each statement of the code.

One of the ways to find that number is to draw a flow chart as follows;

Nodes (circles) represent: each statement of the code Edges (lines) represent: links between the nodes (circles)

In statement coverage, you need to cover all the nodes (circles).

When looking at the above flow chart, we can see that 2 test cases are sufficient to cover the code (see the two bold lines).

How many test cases at minimum are required to test branch / decision coverage?

A. 2
B. 3
C. 4
D. 1

Explanation in favor of the correct Answer:

To calculate the number of test cases required for branch coverage, you need to cover all the edges (lines).

So from the above flow chart, we can cover all the lines / edges with two test cases.

How many test cases at minimum are needed to test the path coverage?

A. 2
B. 3
C. 4
D. 1

Explanation in favor of the correct Answer:

To calculate the number of test cases required for path coverage, you need to cover all paths in the program considering one decision at a time.

There are 3 ways to find the path coverage;

(1) Using McCabe’s technique.

Number of Paths = e – n + 2

e – Edges (lines)

n – Nodes (circles)

From the above example:

Number of Paths = 10 (lines) -9 ( circles) + 2 = 3

(2) Calculate the regions of the flow chart (area enclosed by lines is a region).

Always add outside region.So in this case, the number of paths = 3.

(3) Calculate the decisions (true/false, etc) in the flow chart

Number of Paths = Decisions + 1

There are two decision points in the above chart (if statements)

So the number of paths = 2 + 1 = 3

You can use one of the techniques and find the number of paths. It is better to confirm the answer by using another method. The key is to draw the flow chart correctly.

Q. 49: A College Enrollment application used by ABC College calculates the amount each student has to pay for gym and computer lab usage.

The application asks for Student ID, Name and Student’s major. Then the application calculates the fee. If student’s major is Computer Science, they have to pay the full computer lab fee. If the student’s major is not Computer Science, they have to pay only 1/3 rd of the computer lab fee. All students have to pay for the gym membership.

How many tests are required for path coverage of the above application?

A. 1
B. 2
C. 3
D. 10

Explanation in favor of the correct Answer:

You can draw the flow chart as follows:

So, using the first method;Number of paths = e-n+2 = 5-5+2 = 2

You can confirm the answer using one of the other two methods mentioned above.
