Implementations

impl ProgramTestContext

pub fn genesis_config(&self) -> &GenesisConfig

pub fn increment_vote_account_credits( &mut self, vote_account_address: &Pubkey, number_of_credits: u64, )

Manually increment vote credits for the current epoch in the specified vote account to simulate validator voting activity

pub fn set_account(&mut self, address: &Pubkey, account: &AccountSharedData)

Create or overwrite an account, subverting normal runtime checks.

This method exists to make it easier to set up artificial situations that would be difficult to replicate by sending individual transactions. Beware that it can be used to create states that would not be reachable by sending transactions!

pub fn set_sysvar<T: SysvarId + Sysvar>(&self, sysvar: &T)

Create or overwrite a sysvar, subverting normal runtime checks.

This method exists to make it easier to set up artificial situations that would be difficult to replicate on a new test cluster. Beware that it can be used to create states that would not be reachable under normal conditions!

pub fn warp_to_slot(&mut self, warp_slot: Slot) -> Result<(), ProgramTestError>

Force the working bank ahead to a new slot

pub fn warp_to_epoch( &mut self, warp_epoch: Epoch, ) -> Result<(), ProgramTestError>

pub fn warp_forward_force_reward_interval_end( &mut self, ) -> Result<(), ProgramTestError>

warp forward one more slot and force reward interval end

pub async fn get_new_latest_blockhash(&mut self) -> Result<Hash>

Get a new latest blockhash, similar in spirit to RpcClient::get_latest_blockhash()

pub fn register_hard_fork(&mut self, hard_fork_slot: Slot)

record a hard fork slot in working bank; should be in the past
