// File utilities for testing purposes.
|
|
// The ProjectRootPath() method is a convenient way of getting an absolute
|
|
// path to the project source tree root directory. Using this, it is easy to
|
|
// refer to test resource files in a portable way.
|
|
//
|
|
// Notice that even if Windows platforms use backslash as path delimiter, it is
|
|
// also supported to use slash, so there's no need for #ifdef checks in test
|
|
// code for setting up the paths to the resource files.
|
|
//
|
|
// Example use:
|
|
// Assume we have the following code being used in a test source file:
|
|
// const std::string kInputFile = webrtc::test::ProjectRootPath() +
|
|
// "test/data/voice_engine/audio_long16.wav";
|
|
// // Use the kInputFile for the tests...
|
|
//
|
|
// Then here's some example outputs for different platforms:
|
|
// Linux:
|
|
// * Source tree located in /home/user/webrtc/trunk
|
|
// * Test project located in /home/user/webrtc/trunk/src/testproject
|
|
// * Test binary compiled as:
|
|
// /home/user/webrtc/trunk/out/Debug/testproject_unittests
|
|
// Then ProjectRootPath() will return /home/user/webrtc/trunk/ no matter if
|
|
// the test binary is executed from standing in either of:
|
|
// /home/user/webrtc/trunk
|
|
// or
|
|
// /home/user/webrtc/trunk/out/Debug
|
|
// (or any other directory below the trunk for that matter).
|
|
//
|
|
// Windows:
|
|
// * Source tree located in C:\Users\user\webrtc\trunk
|
|
// * Test project located in C:\Users\user\webrtc\trunk\src\testproject
|
|
// * Test binary compiled as:
|
|
// C:\Users\user\webrtc\trunk\src\testproject\Debug\testproject_unittests.exe
|
|
// Then ProjectRootPath() will return C:\Users\user\webrtc\trunk\ when the
|
|
// test binary is executed from inside Visual Studio.
|
|
// It will also return the same path if the test is executed from a command
|
|
// prompt standing in C:\Users\user\webrtc\trunk\src\testproject\Debug
|
|
//
|
|
// Mac:
|
|
// * Source tree located in /Users/user/webrtc/trunk
|
|
// * Test project located in /Users/user/webrtc/trunk/src/testproject
|
|
// * Test binary compiled as:
|
|
// /Users/user/webrtc/trunk/xcodebuild/Debug/testproject_unittests
|
|
// Then ProjectRootPath() will return /Users/user/webrtc/trunk/ no matter if
|
|
// the test binary is executed from standing in either of:
|
|
// /Users/user/webrtc/trunk
|
|
// or
|
|
// /Users/user/webrtc/trunk/out/Debug
|

// (or any other directory below the trunk for that matter).
