Nice change. Moving the unit test to crit/ sounds like the right thing to do.

This is also a good indicator that we should add some more tests.

@adrianreber crit/images and crit/cmd are being refactored in #109, I'll add the tests there for the parts we currently aren't testing

Sounds good.

One thing I am thinking about is that for unit tests we could always generate test coverage output while using go test. Just to reduce code in the Makefiles. @rst0git what do you think? We can also merge what we have in this PR. Works both for me.

We can have a unit-test target in the top level Makefile (or the Makefile in test) which simply runs
go -coverprofile=$COVER_PROFILE_PATH/coverprofile-unit-test test ./... in the root.

@rst0git works for me. There still seems to be one question open. What about always running unit tests with test coverage results? Unit test coverage does not depend on Go 1.20 and can always be created.

I have added a commit to always run the unit tests with test coverage results.

@rst0git
crit: move unit test to crit/ pkg
91569bf 
To generate code coverage for the unit tests of crit they need to be
part of the crit package. This patch moves the unit test from
'test/crit/' to 'crit/' as a preparation for a subsequent patch where
we would enable test coverage.

crit: run unit tests with coverage results
dbf1473 
There are two ways we can enable test coverage for the unit tests:
1) `-coverprofile` and 2) `-cover`. The first method stores the results
in a file that we can upload with `codecov`. The second method only
outputs the test coverage results to standard output.

This patch set the default value of GOFLAGS to `-cover` to
always show the coverage of unit tests.
