 # Testing
 
-To run the tests, first you'll need to install [vagrant](http://vagrantup.com)
-for your platform. Then run `vagrant up` to create the virtual machines for the
-eureka server tests.
+Tests can be executed using docker container. See the below section to build and start 
+all the required containers. Once fargo container is running:
+
+1. attach shell `docker attach fargo`
+2. Checkout your test branch
+3. execute `go test -v ./...`
 
 The tests may need to be run a couple of times to allow changes to propagate
-between the two eureka servers. To run them, use `go test ./...` from the root
-of the repository. If the tests are failing, try running them again
+between the two eureka servers. If the tests are failing, try running them again
 approximately 30 seconds later.

+# forward port 8080 to local port 49000
