From 14d2747c7e54037e267bcff78b29e65b2181f0fa Mon Sep 17 00:00:00 2001 From: Nicolas Catania Date: Mon, 13 Jul 2009 14:37:49 -0700 Subject: New test player stub to load mock native players. Added a new class TestPlayerStub that takes a magic url in the setDataSource call. Based on the value of the url, the stub is going to load a DL and create the concrete player used during the test. After these initialization steps TestPlayerStub is just a wrapper. Added a new functional test MediaPlayerInvokeTest to demonstrate how a new mock player to test the invoke method can be loaded. Added a new mock player for the invoke test: invoke_mock_media_player.cpp. --- media/libmediaplayerservice/TestPlayerStub.cpp | 196 +++++++++++++++++++++++++ 1 file changed, 196 insertions(+) create mode 100644 media/libmediaplayerservice/TestPlayerStub.cpp (limited to 'media/libmediaplayerservice/TestPlayerStub.cpp') diff --git a/media/libmediaplayerservice/TestPlayerStub.cpp b/media/libmediaplayerservice/TestPlayerStub.cpp new file mode 100644 index 0000000..8627708 --- /dev/null +++ b/media/libmediaplayerservice/TestPlayerStub.cpp @@ -0,0 +1,196 @@ +/* + * Copyright (C) 2009 The Android Open Source Project + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +//#define LOG_NDEBUG 0 +#define LOG_TAG "TestPlayerStub" +#include "utils/Log.h" + +#include "TestPlayerStub.h" + +#include // for dlopen/dlclose +#include +#include +#include +#include // for status_t + +#include "media/MediaPlayerInterface.h" + + +namespace { +using android::status_t; +using android::MediaPlayerBase; + +const char *kTestUrlScheme = "test:"; +const char *kUrlParam = "url="; + +const char *kBuildTypePropName = "ro.build.type"; +const char *kEngBuild = "eng"; +const char *kTestBuild = "test"; + +// @return true if the current build is 'eng' or 'test'. +bool isTestBuild() +{ + char prop[PROPERTY_VALUE_MAX] = { '\0', }; + + property_get(kBuildTypePropName, prop, '\0'); + return strcmp(prop, kEngBuild) == 0 || strcmp(prop, kTestBuild) == 0; +} + +// @return true if the url scheme is 'test:' +bool isTestUrl(const char *url) +{ + return url && strncmp(url, kTestUrlScheme, strlen(kTestUrlScheme)) == 0; +} + +} // anonymous namespace + +namespace android { + +TestPlayerStub::TestPlayerStub() + :mUrl(NULL), mFilename(NULL), mContentUrl(NULL), + mHandle(NULL), mNewPlayer(NULL), mDeletePlayer(NULL), + mPlayer(NULL) { } + +TestPlayerStub::~TestPlayerStub() +{ + resetInternal(); +} + +status_t TestPlayerStub::initCheck() +{ + return isTestBuild() ?
