but web development is not about "making new websites"

Think micro-services supplying REST APIs over HTTP - that's going to be same-y after a few years yes, but behind that is a world of business apps, integration challenges, complex algorithms and calculations - sorry I just see "web development" as "anything that has of will have an http access point" which I mentally count as "pretty much everything from here on in"

Programming tests do generally test for ability to apply known solutions quickly - it's about all they do do. You just have to know the known solutions (oh look calculate primes).

As for finding productive coders - well the amount of false negatives is large, and the false positive rate is probably higher (plenty of people who can waltz through these tests i find fairly poisonous to morale) so I am not a big fan - but if you need to make a first cut this is a good start
