- A flagfile requires manual management with touch and rm, replace it
with an environment variable that can be set more conveniently.
- Removing tools/tests/opgpcard.rs is not necessary, the file it links
to is always generated in build.rs, either with subplot tests or
without. But it is always there, so cargo test does not fail for
that reason.
These need to be run with the virtual smartcard emulation in the
Docker container specified in .gitlab-ci.yml for tests.
The tests are a little simplistic, as it turned out that making
changes to the smart card results in flaky tests. Thus only parts of
opgpcard that don't change the card are tested.
