I'll start off by saying, unrelated to the gist of your question, that this type of question, "Test the item" ones, even for juniors without any previous QA experience, are the stupidest, least useful and crappiest kind of questions you can ask a candidate and I would strongly consider working for a company where the tech interviewer asks this question... even if it is only one question out of a whole bunch.
This type of question needs to die. Fast.
Having said that, between the super-informative title and the body of the questions, I don't really know what you're actually asking!
If you're asking about whether you got all the "correct" testing categories, well, I'm QA for 12 years and don't know half of them (
Component?!?!) or have long forgotten what they mean (
Verify) and I, nor any other QA, have any use for them on daily business, so can't help you there.
If you're asking whether you got the right type of test per category, then absolutely NOT!
automation I don't mean I want you to test the gold content of the clasp using a robot. I mean
Have the robot open-and-close the clasp 10000 times in a row to test the clasp's longevity.
Automation is about having the machine do the boring, mundane, easy to get wrong ("did I already flip the clasp 9990 times, or was it 9989?!") tasks for us.
negative test for an earing would not be that it can't be worn as a nose-ring... you'd be surprised. A better negative test would be: "Try to perform an operation with the earring where it does not function as a piece of jewlery, like turn on the TV with it".
Negative tests are about using the product in ways it wasn't ever meant to be used and verifying nothing bad happens due to the misuse.
But ultimately, what I would like to see is figuring out what the purpose of the earring was, it's inteded use cases and so forth, so what I would like you to submit, had I been a stupid interviewer actually still asking a "test an earring" kind of question was:
- What is the main usage of the earring: is it a children's toy? A teenager's "look-at-me" cry? A grown woman's accessory? The queen of England's gift from her sons to her coming birthday?
- I can tell you that for two of these cases, which I'll leave it for you to figure out, I, as a QA, would not sign off on the product as production-ready!
- What standards, if any, should the earring meet, in terms of safety, quality of materials, durability of clasp? Does it meet them?
- Since we seem to already have a prototype, in the picture above, was it tested for ease of use on a target audience? What was the feedback? (It's always nice when you can "involve" your target audience, let them test your product for you, get their feedback... and if you can have all that for free, then it's even better!)
Actual question like the clasp's durability on average (what does this,
on average tell you, by the way?), or if the earring weighs, on average between 5-10 grams are all valid and important question, that I definetly expect you to ask as a QA of the product, no doubt!
But what I really want you to be is a domain expert on the subject of earrings: know the standards that govern the industry, know what is the expectation of the target audience, anticipate what a clueless (or even right-out malicious) user might use the product for, other than its intended use and have a test for all those aspects.
And if you don't know yet, as I'm sure you're not an expert on diamond earrings just yet, I expect you to be both able and willing to educate yourself on the subject using whatever source of data you can find.
Yes, I know, I probably didn't answer your question (which I still don't really know what it was).
I told you, however, what you could do to not have to ask this kind of questions again.
And let me tell you again, no matter even if you're a rookie with no prior experience, think long and hard before taking an offer from a company whose technical lead is so unimaginative and clueless that he resorts to this kind of questions.
