* It assumes that packages have individual module tests that are run on
  updates. Both is not true with few excaptions only.

* To some degree package testing already involves other packages.
  There is no sharp separation line for integration testing.

* I cannot find, how this is addressed:
  * There are quite a few TeX compilers with quite a few formats.
  * There are lots of classes and tons of packages.
  * Classes and packages provide none up to an endless number of options
    with multiple values and working modes.
  * The number of package combinations and loading order is overwhelming.

* What is tested:
  * Errors: expected or unexpected
  * Warnings: expected or unexpected
  * Messages: expected or unexpected
  * Output: DVI/PS/PDF
  * log file, aux files, ...

* Which system to manage the tests?

* How to deal with the result? But report to package authors?

* ...

Good testing is a huge task requiring lots of "(wo)man power".
