For example, $TEST_DIR is common used in severial tests, and have duplicated code for initialize. These duplicated code not only benifits harddisk vendor, but have inconsistent details, as: convert-tests.sh: lack of mkdir fsck-tests/012-leaf-corruption/test.sh: unnecessary mkdir fsck-tests/013-extent-tree-rebuild/test.sh: unnecessary init misc-tests/XXX ... And severial error message: _fail "unable to create mount point on $TEST_MNT" _fail "failed to create mount point" ... This patch move initizlizaton of $TEST_DIR to common init_env(), to avoid above problem, and init_env() can be used to add more things in future.
