Interview [modified]

[Shahil Shah]

Hello fellow CPians I have been asked to come up with some interview questions on VB.NET for automated testing :doh: . I was thinking of asking general ADO & .NET questions. Any other suggestions? Thanks Shahil

I think Google will help you much better than us. There may even be some articles on that subject here on Code Project.

Q1: What does "Option Explicit" do? If they don't know there is no sense continuing.

Maybe provide some code samples that have syntax or logic errors, and have the applicant correct them?

Testing data in a database is integration testing and not unit testing IMHO so I use it as a trick question when asking about the subject. While I don't expect people to use the same distinction I do I expect them to know why I think it is important. Also, I liked asking people to ask a list of test cases for a deceptively simple task to see if they can come up with a sufficient coverage of the class or unit to be tested. While I never expect a formal proof I do like to see a developer write test cases for the 99.99% case, because to be honest that is what Unit Tests are for. Also, you could ask them to explain why they think C# is better than VB.NET. Since this is a VB.NET, job, clearly, it is a trick question but you can really get some information about the person by throwing them off guard like that, plus it can also be a valid question and is it can be used to illustrate their knowledge of the languages.

Having spent many years designing and programming ATE, one area that I can't stress enough is bit manipulation. Most hardware testing depends a lot on monitoring or modifying status and control bits, and that's not particularly easy in VB. Another area that bites beginning testers is comparisons of measured analog values with thresholds, especially near zero. You could set up some situations where the obvious solution might result in a divide by zero or range violation and ask how the applicant would program the test. Of course, if you're just talking about automated software testing, all of the above is nul.
