Discuss ISTQB ISTQB-CTFL Exam Topic 6 Question 62

Which ONE of the following options MOST ACCURATELY describes branch testing?

AIn branch testing, the coverage items are executable statements. The aim is to design test cases that exercise statements in the code until an acceptable level of coverage is achieved, expressed as a percentage.

BIn branch testing, the coverage items are control flow transfers between decisions, and the aim is to design test cases to exercise flow transfers in the code until an acceptable level of coverage is achieved. Coverage is measured as the number of branches exercised by the test cases divided by the total number of branches expressed as a percentage.

CIn branch testing, the coverage items are branches, and the aim is to design test cases to exercise branches in the code until an acceptable level of coverage is achieved. Coverage is measured as the number of branches exercised by the test cases divided by the total number of branches expressed as a percentage.

DIn branch testing, the coverage items are executable decisions. The aim is to design test cases that exercise statements in the code until an acceptable level of coverage is achieved. Coverage is expressed as a percentage.

Suggested Answer: C

Comprehensive and Detailed In-Depth Explanation:

Branch testing is a structural testing technique that ensures each branch (decision point) in the control flow is executed at least once. The goal is to measure branch coverage, which is the number of branches exercised divided by the total number of branches.

(A) describes statement testing, not branch testing.

(B) and (D) introduce confusion between decisions and statements, whereas branch testing focuses on control flow branches.

In simple terms, branch testing checks that all possible decision outcomes (true/false) are executed, whereas statement testing only ensures that each line of code is executed.

I think option B is the best. It focuses on control flow transfers.

Audry 7 days ago

I lean towards option C too. It clearly defines branches as coverage items.

Bea 12 days ago

Option D confuses decisions with statements. That's not right.

Catarina 17 days ago

I agree with Lashonda. Branch testing is about flow transfers, not just statements.

Dierdre 23 days ago

Option A seems off. It talks about executable statements, not branches.

Temeka 28 days ago

I feel like option C is more accurate. It directly mentions branches.

Not sure if I buy that definition, sounds a bit off to me.

Dottie 1 month ago

Wait, isn't it just about measuring branches? Seems simpler.

Stevie 2 months ago

I thought it was just about executable statements, though.

Vilma 2 months ago

Totally agree, it's all about exercising those branches!

Salina 2 months ago

Branch testing focuses on control flow transfers, right?

Sabrina 2 months ago

Wait, are we sure about this? Seems a bit confusing.

Therese 2 months ago

C is spot on! Branches are the key here.

Loren 2 months ago

I thought it was just about statements, like A says.

Paris 3 months ago

Definitely B! It’s all about those flow transfers.

Mitzie 3 months ago

Branch testing focuses on control flow transfers, right?

Aleta 3 months ago

I thought branch testing focused on decisions, so I’m leaning towards option D, but I’m not entirely confident about the terminology used.

Dean 3 months ago

I feel like option C sounds right since it talks about branches directly, but I’m a bit confused about how it differs from the other options.

Merrilee 3 months ago

I remember practicing a similar question, and I think option B is correct because it specifically mentions control flow transfers, which is key in branch testing.

Jose 4 months ago

I think branch testing is all about testing the different paths in the code, but I'm not sure if it's just about statements or decisions.
