Add standard tests

[olexandr-konovalov]

There is no TestFile component in the PackageInfo.g file. It is recommended to specify a short test (to run for no more than several minutes) which may be used to check that a package works as expected. For deposited packages, these tests are run regularly as a part of the standard GAP test suite. Please see (in GAP 4.9.0 or GAP development version) ?TestPackage, ?Tests files for a GAP package and also ?TestDirectory for more information.

Adding a meaningful test suite for AutoDoc is non-trivial, and TestDirectory is useless for this.

TestDirectory is not the only way to test it of course. You can test something and analyse how did it go, and at the end do

if testresult then
  Print("#I  No errors detected while testing\n");
  QUIT_GAP(0);
else
  Print("#I  Errors detected while testing\n");
  QUIT_GAP(1);
fi;

like e.g. in https://github.com/gap-packages/qaos/blob/master/tst/testall.g

But indeed doing this in some meaningful way for Autodoc is tricky and requires some time to implement.

On a related note, the standard tests need not to be a test used in Travis. The same QaOS package now has a simple offline test specified as standard in PackageInfo.g and extended test for Travis. Perhaps #123 may also do something similar - just building the manual of AutoDoc itself, maybe couple of other packages, and collect code coverage statistics.
