A friend of mine asked me the difference between "verification test" and "demonstration test."
In my understanding, a verification test is an examination conducted to ascertain whether something is true or not because the person conducting the test is not sure about the result while a demonstration test is an examination conducted to show people that something is true.
Please tell me if my understanding is wrong.
I think verification does relate to truth. If you check your tires to verify that they are at 40 psi, you are attempting to confirm the truth of the hypothesis that they are at 40 psi. If they are at 38 psi, your hypothesis has failed, and you have to inflate the tires. If you just check your tires with no preconceived idea of what the pressure is, or should be, that's not verification.
ver·i·fy(vr-f)tr.v. ver·i·fied, ver·i·fy·ing, ver·i·fies1. To prove the truth of by presentation of evidence or testimony; substantiate.
2. To determine or test the truth or accuracy of, as by comparison, investigation, or reference: experiments that verified the hypothesis.verify - definition of verify by the Free Online Dictionary, Thesaurus and Encyclopedia.
