 Testing
 =======
 
-Dotbot testing code uses [Vagrant][vagrant] to run all tests inside a virtual
-machine to have tests be completely isolated from the host machine. The test
-driver relies on the [Sahara][sahara] plugin to snapshot and roll back virtual
-machine state. The tests are deterministic, and each test is run in a virtual
-machine with fresh state, ensuring that tests that modify system state are
-easily repeatable.
