API
Aside from providing a CLI for various tasks, amman also provides commonly used actions, transactions, asserts and more via an API. Please find the API docs here.
CLI
amman [command]
Commands:
amman start Launches a solana-test-validator and the amman relay and/or
mock storage if so configured
amman stop Stops the relay and storage and kills the running solana
test validator
amman logs Launches 'solana logs' and pipes them through a prettifier
amman airdrop Airdrops provided Sol to the payer
amman label Adds labels for accounts or transactions to amman
amman account Retrieves account information for a PublicKey or a label or
shows all labeled accounts
amman run Executes the provided command after expanding all address
labels
Options:
--help Show help [boolean]
--version Show version number [boolean]
Commands: start
amman start <config.js>
If no config.js
is provided amman looks for an .ammanrc.js
file in the current directory.
If that isn't found either it uses a default config.
The config should be a JavaScript module exporting 'validator' with any of the below properties:
- killRunningValidators: if true will kill any solana-test-validators currently running on the system.
- programs: bpf programs which should be loaded into the test validator
- accountsCluster: default cluster to clone remote accounts from
- accounts: array of remote accounts to load into the test validator
- jsonRpcUrl: the URL at which the test validator should listen for JSON RPC requests
- websocketUrl: for the RPC websocket
- ledgerDir: where the solana test validator writes the ledger
- resetLedger: if true the ledger is reset to genesis at startup
- verifyFees: if true the validator is not considered fully started up until it charges transaction fees
Example Configs
Validator/Relay/Storage Config with Defaults
Below is an example config with all values set to the defaults except for an added
program and a relay
and storage
config.
A amman-explorer relay is launched automatically with the validator unless it is running in a CI environment and if a relay is already running on the known relay port, it is killed first.
A mock storage is launched only if a storage
config is provided. In case a storage server
is already running on the known storage port, it is killed first.
import { LOCALHOST, tmpLedgerDir } from '@j0nnyboi/amman'
module.exports = {
validator: {
killRunningValidators: true,
programs: [
{
label: 'Token Metadata Program',
programId: programIds.metadata,
deployPath: localDeployPath('mpl_token_metadata')
},
],
jsonRpcUrl: LOCALHOST,
websocketUrl: '',
commitment: 'confirmed',
ledgerDir: tmpLedgerDir(),
resetLedger: true,
verifyFees: false,
detached: process.env.CI != null,
},
relay: {
enabled: process.env.CI == null,
killlRunningRelay: true,
},
storage: {
enabled: process.env.CI == null,
storageId: 'mock-storage',
clearOnStart: true,
},
}
Config with Remote Accounts
Below is an example of a config where the accounts are being pulled from a specific RPC endpoint.
module.exports = {
validator: {
// By default Amman will pull the account data from the accountsCluster (can be overridden on a per account basis)
accountsCluster: 'https://api.metaplex.solana.com',
accounts: [
{
label: 'Token Metadata Program',
accountId:'metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s',
// marking executable as true will cause Amman to pull the executable data account as well automatically
executable: true,
},
{
label: 'Random other account',
accountId:'4VLgNs1jXgdciSidxcaLKfrR9WjATkj6vmTm5yCwNwui',
// By default executable is false and is not required to be in the config
// executable: false,
// Providing a cluster here will override the accountsCluster field
cluster: 'https://metaplex.devnet.rpcpool.com'
}
]
}
}
Deactivating Test Validator Features
For the different clusters like devnet some features are disabled. By default the locally running solana-test-validator does not disable any features and thus behaves differently than the provided clusters.
In order to run tests in a scenario that is closer to how they would run against a specific cluster you can match the features of it via the matchFeatures config property:
module.exports = {
validator: {
...
// The below disables any features that are deactivated for the `mainnet-beta` cluster
matchFeatures: 'mainnet-beta',
}
}
If you want to explicitly disable a set of features you can do so via the deactivateFeatures property:
module.exports = {
validator: {
...
deactivateFeatures: ['21AWDosvp3pBamFW91KB35pNoaoZVTM7ess8nr2nt53B'],
}
}
NOTE: that only one of the above properties can be set
