Which of the following is NOT a typical debugging activity when a failure is triggered by dynamic testing?

AReproducing the failure

BAdding new test cases

CFixing the cause

DDiagnosing the root cause

Show Suggested Answer

Suggested Answer: D

According to the ISTQB Glossary of Testing Terms, Version 4.0, 2018, page 18, a failure is ''an event in which a component or system does not perform a required function within specified limits''. In this case, the calculator software does not perform the required function of calculating the correct result for 5+6 within the specified limits of accuracy and precision. Therefore, this is an example of a failure.

The other options are incorrect because:

A mistake is ''a human action that produces an incorrect result'' (page 25). A mistake is not an event, but an action, and it may or may not lead to a failure. For example, a mistake could be a typo in the code, a wrong assumption in the design, or a misunderstanding of the requirement.

A fault is ''a defect in a component or system that can cause the component or system to fail to perform its required function'' (page 16). A fault is not an event, but a defect, and it may or may not cause a failure. For example, a fault could be a logical error in the code, a missing specification in the design, or a contradiction in the requirement.

An error is ''the difference between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition'' (page 15). An error is not an event, but a difference, and it may or may not result in a failure. For example, an error could be a rounding error in the calculation, a measurement error in the observation, or a deviation error in the condition.

Diagnosing the root cause is where the real work happens.

From what I recall, reproducing the failure and diagnosing the root cause are standard steps. I feel like adding new test cases might not be typical in this scenario.

I’m a bit confused. I thought fixing the cause was part of debugging, but now I’m wondering if adding new test cases is really necessary in this context.

I remember practicing a question like this, and I think diagnosing the root cause is essential in debugging. Adding new test cases feels like it might not fit here.

I think reproducing the failure is definitely a typical activity, but I'm not sure about adding new test cases. That seems a bit off.

Okay, let's see. Reproducing the failure, adding new test cases, fixing the cause, and diagnosing the root cause. I think I've got a good handle on this.

Hmm, I'm a bit unsure about this one. I'll need to think through the debugging process carefully to figure out which activity is the odd one out.

This seems like a straightforward debugging question. I'll focus on identifying the typical debugging activities and then determine which one is not typical.

I'm a little confused by this question. Debugging can involve so many different steps, and I'm not sure which one would be considered "not typical." I'll have to think this through step-by-step.

This seems straightforward - the bank can retain the full Rs. 50,000 since that's the amount of the loan, and the remaining Rs. 10,000 from the security value has to be paid back to the borrower.

Ha! I bet the developers who wrote this question have never had to debug a real-world application. They're probably still living in their test-driven development bubble.

I think the answer is B) Adding new test cases. Debugging is more about analyzing the existing test cases and fixing the root cause, not creating new ones.
