Thank you for submitting the issue and logs!

I have seen check and test used interchangeably for executing a
testsuite. I thought users would appreciate the ability to choose
whichever term they generally use, but if one option seems sufficient,
I can remove the other.

No, but I can see where I may have created that confusion. I can update
the documentation to make this more clear.

Yes? Depending on what a package's testsuite looks like, it should
ensure that local changes to a shared library (that has previously been
installed) will be utilized when linking to an executable, instead of an
old installed version.

No, this should be specific to "--mode=finish" and "--mode=install" for
shared libraries where the shared library cache may be updated by
finish_cmds. The command(s) should not have any effect on other libtool
modes. For libtool's testsuite, I have been utilizing:

   make check LIBTOOLFLAGS=--test

For packages using libtool, a package testsuite could be built, and
then, the shared libraries within could be changed and rebuilt without
the need to install those changes.

Interactive invocations of src/prog should operate as expected for the
shared libraries it has been linked to. I think --test and --check
should only be useful for checking and testing of local changes to
shared libraries, without the need to install the updated shared
library. I have only seen this as an issue with ldconfig on OpenBSD 7.5.
Other versions of ldconfig do not seem to update the shared library
cache for these local libraries during testing, but I have not put much
time into understanding the differences.
