To execute the tests, install mocha and run the following in the root of the project:

npm install -g mocha
mocha test --recursive

It's important to run mocha with the --recursive flag, as most tests are located in nested folders.

To test code coverage of the tests, install istanbul and run it:

npm install -g istanbul
istanbul cover _mocha -- test --recursive

Note the underscore before mocha, and the -- surrounded by spaces after _mocha. See also gotwarlost/istanbul#44.
