Bats 1.7.0 emits a warning if a feature that is only available starting
from a certain version of Bats onwards is used without specifying that
version [1]:
BW02: Using flags on `run` requires at least BATS_VERSION=1.5.0. Use
`bats_require_minimum_version 1.5.0` to fix this message.
(from function `bats_warn_minimum_guaranteed_version' in file
/usr/lib/bats-core/warnings.bash, line 32,
from function `run' in file
/usr/lib/bats-core/test_functions.bash, line 227,
in test file test/system/001-version.bats, line 27)
Note that bats_require_minimum_version itself is only available from
Bats 1.7.0 [2]. Hence, even though the specific feature here (using
flags on 'run') only requires Bats >= 1.5.0, in practice Bats >= 1.7.0
is needed. Fortunately, commit e22a82fec8 already added a
dependency on Bats >= 1.7.0. So, there's nothing to worry about.
