Quick help to get started with Google Test for WinMerge

As name suggest, this test set uses Google's unit testing framework. So first you need to get Google Test sources from:

http://code.google.com/p/googletest/ [download the .zip file for Windows]

Unzip and compile Google Test library

Unzip the Google Test sources to some folder. Pick a folder you can keep around (not some temp folder) because you'll need the header files every time you compile unit tests.

Open solution file to Visual Studio. The file is in subfolder msvc\gtest.sln

Build the 'Release' target of 'gtest' project. You don't need to build other projects or targets. Indeed, 'rebuild all' for the solution does not work.

Copy the gtest.lib file from msvc\Release subfolder to Testing\GoogleTest- folder in WinMerge source tree.

Setup Visual Studio for Google Test

As mentioned earlier Google Test header files are needed to compile the tests. As the Google Test was unzipped to separate folder we must first tell VS where to find those headers.

Add the gtest-[version]\include -folder to Visual Studio's include file folders:

• Open Options -dialog in Visual Studio
• Select Projects and solutions
• Select VC++ Directories
• Select Include files
• Add gtest-[version]\include -folder as LAST folder in that list

Open the test project into Visual Studio and compile

Open the testing project to Visual Studio (VS 2003 and later work) and compile Release -target of the project.

Run the tests

Open the Command Prompt and CD to folder where executable were build, usually [projectname]/Release

Run the executable.

While the testing runs it prints progress information and info about passed/ failed tests.
