通常，本地测试依赖于本地验证器上默认不可用的程序和帐户。
Solana CLI 允许以下操作：

• 下载程序和账户
• 将程序和帐户加载到本地验证器

如何从主网加载账户

可以将JUP代币铸币账户下载到文件中：

# solana account -u <source cluster> --output <output format> --output-file <destination file name/path> <address of account to fetch>
solana account -u m --output json-compact --output-file jup.json JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN

然后通过在启动验证器时传递帐户的文件和目标地址（在本地集群上）将其加载到您的本地网络：

# solana-test-validator --account <address to load the account to> <path to account file> --reset
solana-test-validator --account JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN jup.json --reset

同样，也可以下载 Openbook 程序：

# solana program dump -u <source cluster> <address of account to fetch> <destination file name/path>
solana program dump -u m srmqPvymJeFKQ4zGQed1GFppgkRHL9kaELCbyksJtPX openbook.so

然后通过在启动验证器时传递程序的文件和目标地址（在本地集群上）将其加载到您的本地网络：

# solana-test-validator --bpf-program <address to load the program to> <path to program file> --reset
solana-test-validator --bpf-program srmqPvymJeFKQ4zGQed1GFppgkRHL9kaELCbyksJtPX openbook.so --reset
