I think if a developer has nothing in the public domain nor can demonstrate some code they have written to you in person then that is the only time a code test is valid. I agree with many here - I have over 2 decades of experience writing code, I see no reason why I should waste an hour of my time writing something asinine that I probably did as part of my university course (Palindrome detectors etc) when you could easily see my capabilities online, hell I have even linked to them all for you on my LinkedIn....
