Autotest relies on filesystem polling to detect modifications in source code files. In other words: The filesytem is constantly being traversed which causes quite some load on both the CPU and the harddrive. This is not healthy for your Mac and if you are working on a portable computer, it will drain your battery.
Apple has introduced FSEvent with Mac OS X 10.5 which is a very efficient way to have the operating system monitor file alterations. This gem teaches autotest to use FSEvent and therefore be nice to your Mac.

And securely install the bundle:
bundle install --trust-policy MediumSecurity
Then add the following line after all other requires in your
Autotest Binary Not Present
Make sure you have either the ZenTest gem or the autotest-standalone gem installed. This dependency has been dropped as of autotest-fsevent-0.2.3 in order to allow any compatible test suite.
Compilation of fsevent_sleep Failed
Make sure you have Xcode (Mac OS X Development Suite) installed. You can download it for free from:
If you don't want to install Xcode, download the prebuilt fsevent_sleep binary, make the downloaded binary executable and install the gem as follows:
