ISTQB Exam CT-TAE Topic 8 Question 38 Discussion

Actual exam question for ISTQB's CT-TAE exam

Question #: 38
Topic #: 8

You have executed an automated test suite for a product that was released into production. Although all the tests passed, there was a major failure in production in an area that was covered well by your automated tests.

You have run the automated tests again and one of the tests is now failing and this is directly related to the production defect that was raised. You decide to run the automated test suite again on the same version of the SUT and the test now passes.

What SHOULD you do now to verify the validity of the automated tests?

ARemove the intermittently failing test from the test suite and investigate the reason why the test sometimes passes and sometimes fails.

BCheck that the production defect that was reported was an actual defect

CRun the automated test suite again and if the test now passes - do nothing

Ah, the old 'pass one, fail one, pass one' routine. Classic software shenanigans. I'd be tempted to go with option C and just roll the dice again, but that's probably not the best approach. Hmm...

I've seen this kind of thing before. It's like the software is having a mood swing or something. I'd go with option B - make sure the production defect was legit before doing anything else.

Intermittently failing tests? That's a new one. Sounds like we need to dive into that reference. I'm leaning towards option D, but let's see what the others have to say.

But shouldn't we also check if the production defect was a real issue before making any changes to the test suite?

This is just bizarre. How can a test pass one time and fail the next? Clearly, the automated tests are not reliable. I'd say option A is the way to go - get to the root of this problem.
