David Alan Gilbert" , peterx@redhat.com Test the new OOB capability. It's mostly the reverted OOB test, but differs in that: - It uses the new qtest_init_with_qmp_format() to create the monitor with the new monitor parameter "-mon x-oob" - Squashed the capability tests on greeting message - Don't use qtest_global any more, instead use self-maintained QTestState, which is the trend Signed-off-by: Peter Xu --- tests/qmp-test.c | 84 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 84 insertions(+) diff --git a/tests/qmp-test.c b/tests/qmp-test.c index 558e83540c..4d15b0fca5 100644 --- a/tests/qmp-test.c +++ b/tests/qmp-test.c @@ -134,6 +134,89 @@ static void test_qmp_protocol(void) qtest_quit(qts); } +/* Tests for Out-Of-Band support. */ +static void test_qmp_oob(void) +{ + QTestState *qts; + QDict *resp, *q; + int acks = 0; + const QListEntry *entry; + QList *capabilities; + QString *qstr; + const char *cmd_id; + const char *qmp_params = "-chardev socket,path=%s,nowait,id=char0 " + "-mon chardev=char0,mode=control,x-oob=on"; + + qts = qtest_init_with_qmp_format(common_args, qmp_params); + + /* Ignore the greeting message. */ + resp = qtest_qmp_receive(qts); + q = qdict_get_qdict(resp, "QMP"); + g_assert(q); + capabilities = qdict_get_qlist(q, "capabilities"); + g_assert(capabilities && !qlist_empty(capabilities)); + entry = qlist_first(capabilities); + g_assert(entry); + qstr = qobject_to(QString, entry->value); + g_assert(qstr); + g_assert_cmpstr(qstring_get_str(qstr), ==, "oob"); + QDECREF(resp); + + /* Try a fake capability, it should fail. */ + resp = qtest_qmp(qts, + "{ 'execute': 'qmp_capabilities', " + " 'arguments': { 'enable': [ 'cap-does-not-exist' ] } }"); + g_assert(qdict_haskey(resp, "error")); + QDECREF(resp); + + /* Now, enable OOB in current QMP session, it should succeed. */ + resp = qtest_qmp(qts, + "{ 'execute': 'qmp_capabilities', " + " 'arguments': { 'enable': [ 'oob' ] } }"); + g_assert(qdict_haskey(resp, "return")); + QDECREF(resp); + + /* + * Try any command that does not support OOB but with OOB flag.
