 ### Run Tests
 
-Before running the tests, you will need to spin up a [TestRPC](https://www.npmjs.com/package/ethereumjs-testrpc) instance and deploy all the 0x smart contracts.
-
-In a separate terminal, start TestRPC (a convenience command is provided as part of this repo)
-
 ```bash
-yarn testrpc
-```
-
-Then in your main terminal run
-
-```
-cd packages/contracts
-yarn migrate
-cd ..
-```
-
-And finally from the root project directory run
-
-```bash
-yarn lerna:run test
+yarn lerna:test
