 ## Integration Tests
-There is a suite of integration tests that will run for the drivers.  In order
-to use these you must export the corresponding environment variables for each
-driver as these perform the actual actions (start, stop, restart, kill, etc).
+We utilize [BATS](https://github.com/sstephenson/bats) for integration testing.
+This runs tests against the generated binary.  To use, make sure to install
+BATS (use that link).  Then run `./script/build` to generate the binary.  Once
+you have the binary, you can run test against a specified driver:
 
-By default, the suite will run tests against all drivers in master.  You can
-override this by setting the environment variable `MACHINE_TESTS`.  For example,
-`MACHINE_TESTS="virtualbox" ./script/run-integration-tests` will only run the
-virtualbox driver integration tests.

-You can set the path to the machine binary under test using the `MACHINE_BINARY`
-environment variable.
+You can also run the general `cli` tests:
 
-To run, use the helper script `./script/run-integration-tests`.
