If you arrived here then it is via an old link, as ReactTests has been removed and has become part of the ReactWebPack.CoreRC2 project.

I initially set up the React Unit Tests as a separate project, but this proved to be a mistake. The problem is being seperate from the code it was testing can cause a multiple copies of React error in some cases.

Please have a look at the top-level README file for more information on the Unit Tests and articles.
