From fa198ad9bdef7303d4e3613c69ea00eece6b3a75 Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Mon, 26 Mar 2018 14:39:01 +0800 Subject: [PATCH] tests: qmp-test: add test for new "x-oob" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Test the new OOB capability. It's mostly the reverted OOB test (see commit 4fd78ad7), but differs in that: - It uses the new qtest_init_without_qmp_handshake() parameter to create the monitor with "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 Message-Id: <20180326063901.27425-9-peterx@redhat.com> Reviewed-by: Eric Blake [eblake: rebase to qtest_init changes] Reviewed-by: Marc-André Lureau Tested-by: Christian Borntraeger Signed-off-by: Eric Blake --- tests/qmp-test.c | 82 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 82 insertions(+) diff --git a/tests/qmp-test.c b/tests/qmp-test.c index 2134d95db9..772058fc4c 100644 --- a/tests/qmp-test.c +++ b/tests/qmp-test.c @@ -135,6 +135,87 @@ 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; + + qts = qtest_init_without_qmp_handshake(true, common_args); + + /* Check 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.
