Required Methods§

Source

fn generate_accounts(&mut self, number_of_accounts: u8) -> Vec<Keypair>

Adds a requested number of account with initial balance of 1_000 SOL to the test environment

Source

fn add_account_with_data( &mut self, pubkey: Pubkey, owner: Pubkey, data: &[u8], executable: bool, )

Add a rent-exempt account with some data to the test environment.

Source

fn add_account_with_lamports( &mut self, pubkey: Pubkey, owner: Pubkey, lamports: u64, )

Adds an account with the given balance to the test environment.

Source

fn add_account_with_packable<P: Pack>( &mut self, pubkey: Pubkey, owner: Pubkey, data: P, )

Adds a rent-exempt account with some Packable data to the test environment.

Source

fn add_account_with_borsh<B: BorshSerialize>( &mut self, pubkey: Pubkey, owner: Pubkey, data: B, )

Adds a rent-exempt account with some Borsh-serializable to the test environment

Source

fn add_token_mint( &mut self, pubkey: Pubkey, mint_authority: Option<Pubkey>, supply: u64, decimals: u8, freeze_authority: Option<Pubkey>, )

Adds an SPL Token Mint account to the test environment.

Source

fn add_token_account( &mut self, pubkey: Pubkey, mint: Pubkey, owner: Pubkey, amount: u64, delegate: Option<Pubkey>, is_native: Option<u64>, delegated_amount: u64, close_authority: Option<Pubkey>, )

Adds an SPL Token account to the test environment.

Source

fn add_associated_token_account( &mut self, mint: Pubkey, owner: Pubkey, amount: u64, delegate: Option<Pubkey>, is_native: Option<u64>, delegated_amount: u64, close_authority: Option<Pubkey>, ) -> Pubkey

Adds an associated token account to the test environment. Returns the address of the created account.

Source

fn add_bpf_program( &mut self, program_name: &'static str, program_id: Pubkey, program_authority: Option<Pubkey>, process_instruction: Option<BuiltinFunctionWithContext>, )

Adds a BPF program to the test environment. The program is upgradeable if Some program_authority is provided.

Source

fn add_bpf_program_with_program_data( &mut self, program_name: &'static str, program_id: Pubkey, program_authority: Option<Pubkey>, program_data: Pubkey, process_instruction: Option<BuiltinFunctionWithContext>, )

Adds a BPF program to the test environment. The program is upgradeable if Some program_authority and then providing the program data account This is useful for those programs which the program data has to be a spefic one, if not, use ProgramTestExtension::add_bpf_program

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
