Testsuite for ucf
=================
The testsuite is run with ./run. It utilises unshare(1) to establish a separate
mount namespace for each test; /var/cache/debconf, /var/lib/ucf and
$UCF_TEST_TARGET are each mounted as a tmpfs. This prevents the tests from
interfering with the host system whilst not requiring elevated privileges. If
the call to unshare(1) fails, the test is skipped with a warning.
Each test is contained in a separate subdirectory. The files in each test
directory are:-
- test an executable that runs the test. Installations and
filesystem modifications by ucf and friends should be made
beneath the $UCF_TEST_TARGET directory.
- expected/output the expected stdout of `test`.
- expected/target the expected contents of $UCF_TEST_TARGET after the script is run.
- expected/state the expected contents of /var/lib/ucf after the script has run.
By default, the tests are run using the scripts in the source root
directory. This can be overridden with the UCF_TEST_BINDIR environment
variable. Ensure it ends with a path separator ('/'). If the variable is set to
null (UCF_TEST_BINDIR=), the scripts will be searched in PATH.
