Dear Piotr,
I also recommend to use tests - many GAP packages have them in the tst
directory, for example see the Example package at
https://github.com/gap-packages/example/tree/master/tst
Instead of continuing in the same GAP session with multiple reloads, you can
leave that to the situations when you need to test the code interactively,
otherwise gap tst/testall.g starts new clean session, loads your package, runs
tests and reports discrepancies, if any.
Please see also
https://carpentries-incubator.github.io/gap-lesson/04-testing/index.html
and
https://www.gap-system.org/Manuals/doc/ref/chap76.html#X8559D1FF7C9B7D14
Best wishes
Alexander
