Discuss ISTQB CTFL-Foundation Exam Topic 2 Question 53

Which of the following statements BEST describes one of the seven key principles of software testing?

AAutomated tests are better than manual tests for avoiding the Exhaustive Testing.

BExhaustive testing is, with sufficient effort and tool support, feasible for all software.

CIt is normally impossible to test all input / output combinations for a software system.

DThe purpose of testing is to demonstrate the absence of defects. The purpose of testing is to demonstrate the absence of defects.

Suggested Answer: C

One of the seven key principles of software testing is that exhaustive testing is impossible. This principle highlights the impracticality of testing all possible input and output combinations due to the vast number of permutations. Instead, risk-based and prioritized testing approaches should be used to focus on the most critical areas. This principle is fundamental in the ISTQB CTFL Syllabus, emphasizing the importance of efficient test strategy over attempting exhaustive testing.

Exactly! Balance is key in testing methods.

I feel like A is too extreme. Manual tests have value.

Vonda 1 month ago

Right, but C is more realistic overall.

Lachelle 1 month ago

True, but it’s still a goal.

Josephine 1 month ago

But D is misleading. Testing can't prove absence of defects.

Carli 2 months ago

D sounds good too. Testing shows we found no defects.

Vonda 2 months ago

Agreed, C makes sense. Too many combinations.

Lachelle 2 months ago

I think C is the best choice. Can't test everything!

Weldon 2 months ago

D is a common misconception; testing can't prove no defects exist.

Mayra 2 months ago

Wow, I thought exhaustive testing was possible with enough time!

Rebeca 2 months ago

A is misleading, manual tests still have their place.

Bettina 3 months ago

I disagree, B makes sense with the right tools.

Jacqueline 3 months ago

C is spot on! You can't test everything.

Jamey 3 months ago

I vaguely recall that testing is more about finding defects rather than proving their absence, so I might lean towards option D being misleading.

Thaddeus 3 months ago

I feel like we practiced a question similar to this, and I think the key principle is about the impossibility of covering all combinations, which aligns with option C.

Elouise 3 months ago

I'm not entirely sure, but I remember something about exhaustive testing being impossible for complex systems. Maybe that's option C?

Kristeen 4 months ago

I think option C sounds familiar because we discussed how it's impractical to test every possible scenario in class.
