apitest

Simple comparison framework for APIs

BUILDING

To build, you will need a Cmake 2.8 (or later) install. C++11 features are used, so you will need to ensure you have at least the requested compiler for your platform. See below for platform-specific instructions to build:

Windows (from a cmd prompt in the directory README.md is located in)

mkdir _out
cd _out
cmake -G "Visual Studio 11" ..
start apitest.sln

The Debug and Release configurations are run regularly, so they should continue work just fine for you out of the box.

Unix / OSX (from a cmd prompt in the directory README.md is located in)

mkdir _out
cd _out
cmake -G "Unix Makefiles" ..
make

To run apitest (from a cmd prompt in the directory README.md is located in)

cd bin
./apitest

Changing Problems / Solutions

• The active problem is changed by pressing the left or right arrow keys.
• The active solution is changed by pressing the up or down arrow keys.
• The active API (if on a platform that supports multiple APIs) is changed by pressing 'a'.

Notes on benchmarking

If you are benchmarking from withing visual studio, you need to disable the debug heap. This applies to bother Release and Debug configurations. This is accomplished by specifying _NO_DEBUG_HEAP=1 in the environment field of the Debug Properties page of apitest (in Visual Studio).

Other useful notes

apitest supports command line options. To see the complete list, run apitest with '-h' on the command line, which will print out a (hopefully) useful help. At the time of this writing, you can specify the active problem, solution and api from the command line, as well as the resolution (specified as -r width height). You can also specify benchmark mode, which will either run the full suite of tests, or if you only chose a single problem/solution via -p/-s will benchmark that single test.
