Currently, using an invalid XML in tests fails, because
the schema test expects all of them to be valid.
Treat files with -invalid.xml suffix as invalid and expect
them to fail validation.
(cherry picked from commit 470d5c4654)
Commit 6fdbce12 attempted to sort the list of tests, but failed
(without quotes, echo merges all the tests into a single line,
so there was nothing to sort).
* tests/schematestutils.sh: Fix thinko in previous patch.
Having a test that depends on file system timestamps and/or inode
allocation order gives non-deterministic output.
* tests/schematestutils.sh: Run test in deterministic order.
* tests/test-lib.sh: "echo -n" is not portable. Use printf instead.
Remove unnecessary uses of "eval-in-subshell" (subshell is sufficient).
Remove uses of tests' -a operator; it is not portable.
Instead, use "test cond && test cond2".
* tests/schematestutils.sh: Replace use of test's -a.
Only print out '.' for each test case, full test output can be
re-enabled with VIR_TEST_VERBOSE=1, or VIR_TEST_DEBUG=XXXX
Sample output now looks like
TEST: statstest
........................................ 40
................................... 75 OK
PASS: statstest
TEST: qparamtest
................................ 32 OK
PASS: qparamtest
TEST:
............ 12 OK
