TeX distributions: They would have to do it for every package update
of every package. Many problems arise from compatibility issues
between packages.

hyperref: Yes, a better test infrastructure would be nice.
For some of my packages I have already some more or less
execessive tests. In case of hyperref:
* The package infrastructure is different.
* The package is much more complex, e.g., it has lots of options.
* It supports many drivers. I do not even have access to some of them
  (dvipsone, dviwindo, textures, ...).
* I do not know tools that make testing in the TeX world easier
  (except qstest, but that is limited to LaTeX + e-TeX).
  Also tools are needed that analyze the output file formats:
  link names, link positions, bookmarks, ...
* And most important the interfaces need to be clarified and more precisely
  defined and even simplified if possible. Currently there are many
  differences between the drivers.
* ...

Designing, implementing a reasonable test infrastructure with developing
all the needed tools is a software project much larger than hyperref itself.

Hoewever, the man power of the maintainers of hyperref is limited,
it is just one person.

Then help in writing tools that assist in automatic tests, for example.

It is on my ToDo list ...
