 ## Testing your contracts

 ## Using buidler in your own scripts
 You can leverage Buidler's infrastructure and configuration in your own scripts.

 You can also build them as standalone scripts and run them directly without `buidler`, you just need to import the [Buidler Runtime Environment](#Buidler-Runtime-Environment) with `require("@nomiclabs/buidler")`. If you run them this way, you have to use environment variables to pass arguments directly to Buidler (e.g. `BUIDLER_NETWORK=develop`).
