Discuss ISQI CTFL_Syll2018 Exam Topic 6 Question 112

Which of the following is NOT an example of a common test metric?

APercentage of work done in test environment creation

BAverage number of expected defects per requirement

CNumber of test cases run

DDeviation from test milestone dates

Suggested Answer: B

Test metrics are quantitative measures that are used to monitor, control, and improve the test process and its outcomes. Test metrics can be collected at different levels of testing (test case, test suite, test project, etc.) and can be used for different purposes (planning, estimation, execution, evaluation, etc.). Some examples of common test metrics are:

Percentage of work done in test environment creation: This metric indicates how much effort has been spent on setting up and maintaining the test environment, which includes hardware, software, network, data, tools, etc., that are required for conducting the test activities.

Number of test cases run: This metric indicates how many test cases have been executed during a given period or phase of testing.

Deviation from test milestone dates: This metric indicates how much delay or ahead of schedule the test activities are compared to the planned dates.

Defect density: This metric indicates how many defects have been found per unit of size or functionality of the system under test.

Average number of expected defects per requirement is not a common test metric because it is not easy to estimate or measure how many defects are likely to be found for each requirement. Moreover, this metric does not provide useful information for improving the test process or evaluating the test results. You can find more information about test metrics inA Study Guide to the ISTQB Foundation Level 2018 Syllabus, Chapter 5, Section 5.41.

B and C are standard metrics, for sure.

Roslyn 10 months ago

Wait, are we sure about that? I thought environment setup was important too.

Tiera 10 months ago

A is definitely not a common metric.

Nickole 10 months ago

D seems off too, but I guess it could be relevant in some contexts.

Quiana 11 months ago

I agree, it's more about the outcomes, not the setup.

Tamar 11 months ago

Deviation from test milestone dates seems more like a project management metric rather than a testing metric, but I could be wrong.

Reynalda 11 months ago

I’m leaning towards option A as the one that doesn't fit, but I could be mixing it up with something else we studied.

Mozelle 11 months ago

I remember practicing a question about test metrics, and I feel like the average number of expected defects per requirement is a valid metric.

Latia 11 months ago

I think the percentage of work done in test environment creation might not be a common test metric, but I'm not entirely sure.

Talia 12 months ago

I've got a good feeling about this. Percentage of work done in test environment creation doesn't seem to fit with the other options. That's my final answer.

Dino 12 months ago

I'm a bit unsure about this one. I'll need to review my notes on test metrics to make sure I don't miss anything important.

Justine 12 months ago

Okay, let's see. Average number of expected defects, number of test cases run, and deviation from test milestones - those all seem like common test metrics. I'll have to eliminate those.

King 1 year ago

Percentage of work done in test environment creation? That doesn't sound like a typical test metric to me. I'll mark that as the answer.

Leatha 1 year ago

Hmm, this looks like a tricky one. I'll need to think carefully about the common test metrics I've learned.

Daren 1 year ago

I'm going with option A. I mean, who measures the percentage of work done in the test environment? That's just weird.

Option A does seem a bit odd, but it's actually a common test metric.

Angella 1 year ago

Ha! I bet the test creators are trying to catch us with that 'not an example' thing. Tricky, tricky!

Barney 1 year ago

Option B is interesting, but I'm not sure it's a common test metric. Wouldn't that be more of a requirement analysis metric?

Levi 1 year ago

↳ replying to Barney

C) Number of test cases run

Leonida 1 year ago

↳ replying to Barney

B) Average number of expected defects per requirement

Glen 1 year ago

↳ replying to Barney

A) Percentage of work done in test environment creation

Lili 1 year ago

I'd say option D is the odd one out here. Deviation from test milestone dates sounds more like a project management KPI to me.

Shasta 1 year ago

↳ replying to Lili

Yeah, I think it's more about tracking progress rather than measuring test effectiveness.

Percy 1 year ago

↳ replying to Lili

I agree, option D does seem more related to project management than testing.

Maryrose 1 year ago

↳ replying to Lili

Yeah, I think so too. The other options are more directly related to testing metrics.

Nakita 1 year ago

↳ replying to Lili

I agree, option D seems more related to project management than testing.

Antonio 1 year ago

I agree with Cecil, C) Number of test cases run doesn't seem like a common test metric to me.

Larae 1 year ago

I'm not sure, but I think A) Percentage of work done in test environment creation is also a common test metric.

Hyman 1 year ago

I disagree, I believe it's D) Deviation from test milestone dates.

Sabrina 1 year ago

Hmm, I think option A is not a common test metric. That's more like a project management metric, right?

Belen 1 year ago

↳ replying to Sabrina

I believe option D is the correct answer, deviation from test milestone dates is not a common test metric.

Moira 1 year ago

↳ replying to Sabrina

I think option C is not a common test metric either, it's more about test execution.

Elenor 1 year ago

↳ replying to Sabrina

I agree, option A is more related to project management than testing.

Cecil 1 year ago

I think the answer is C) Number of test cases run.
