Testing Introduction These test instructions should be executed from a command line interface wallet (CLI) that has been built for your test environment. For example, testing performed with the public testnet requires the CLI built for the BitShares Public Testnet. The following instructions were executed on a private testing environment where TEST was the core token. These exact instructions may differ on your test environment in the following ways:

The core token may be different than "TEST" (e.g. "BTS"). Modify the commands to use your core token symbol. The account names that are created might already exist in your test environment. Check for their existence by running get_account <ACCOUNT_NAME>. Modify the commands to use alternate account names). The asset names that are created might already exist in your test environment. Check for the existence by running get_asset <ACCOUNT_NAME>.
