Comment(by lesserwhirls):

 Sorry for the delay - I am working on the tests as I develop a few
 examples based on the book "The Illustrated Wavelet Transform Handbook" by
 Napler Addison.  I'll post these as soon as I'm finished.

 I've also done comparisons with the CWT function in Matlab (2008b, will
 redo for 2009a), and the results from my code are comparable when scaled
 properly (Matlab does some interesting things in terms of scaling).  I've
 also compared against the more widely used (at least in atmospheric
 sciences) routines by C. Torrence and G. Compo
 (http://paos.colorado.edu/research/wavelets/software.html) and again, the
 results from my code compared well with the results from their code.

 Replying to [comment:3 josefpktd]:
 > I didn't see any tests at all and no examples that could be converted to
 tests.
