From e64f02ad9ec7d027e0360e3964e88a497d5df02f Mon Sep 17 00:00:00 2001 From: Arun Raghavan Date: Wed, 2 Mar 2011 10:51:56 +0530 Subject: tests: Add a trivial test for the extended API This is just sync-playback.c modified to use the extended API. We need something more sophisticated for properly testing the compressed formats, but that is a non-trivial task in itself. --- src/Makefile.am | 6 ++ src/tests/extended-test.c | 197 ++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 203 insertions(+) create mode 100644 src/tests/extended-test.c (limited to 'src') diff --git a/src/Makefile.am b/src/Makefile.am index 1b8b447e..e3217043 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -274,6 +274,7 @@ TESTS_BINARIES = \ mcalign-test \ pacat-simple \ parec-simple \ + extended-test \ strlist-test \ close-test \ voltest \ @@ -439,6 +440,11 @@ parec_simple_LDADD = $(AM_LDADD) libpulse.la libpulse-simple.la libpulsecommon-@ parec_simple_CFLAGS = $(AM_CFLAGS) parec_simple_LDFLAGS = $(AM_LDFLAGS) $(BINLDFLAGS) +extended_test_SOURCES = tests/extended-test.c +extended_test_LDADD = $(AM_LDADD) libpulse.la libpulsecommon-@PA_MAJORMINOR@.la +extended_test_CFLAGS = $(AM_CFLAGS) +extended_test_LDFLAGS = $(AM_LDFLAGS) $(BINLDFLAGS) + strlist_test_SOURCES = tests/strlist-test.c strlist_test_CFLAGS = $(AM_CFLAGS) strlist_test_LDADD = $(AM_LDADD) $(WINSOCK_LIBS) libpulsecore-@PA_MAJORMINOR@.la libpulse.la libpulsecommon-@PA_MAJORMINOR@.la diff --git a/src/tests/extended-test.c b/src/tests/extended-test.c new file mode 100644 index 00000000..ec3cc53c --- /dev/null +++ b/src/tests/extended-test.c @@ -0,0 +1,197 @@ +/*** + This file is part of PulseAudio. + + PulseAudio is free software; you can redistribute it and/or modify + it under the terms of the GNU Lesser General Public License as published + by the Free Software Foundation; either version 2.1 of the License, + or (at your option) any later version. + + PulseAudio is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
