Struct MolluskContext 

pub struct MolluskContext<AS: AccountStore> {
    pub mollusk: Mollusk,
    pub account_store: Rc<RefCell<AS>>,
}

A stateful wrapper around Mollusk that provides additional context and convenience features for testing programs.

MolluskContext maintains persistent state between instruction executions, starting with an account store that automatically manages account lifecycles. This makes it ideal for complex testing scenarios involving multiple instructions, instruction chains, and stateful program interactions.

Note: Account state is only persisted if the instruction execution was successful. If an instruction fails, the account state will not be updated.

The API is functionally identical to Mollusk but with enhanced state management and a streamlined interface. Namely, the input accounts slice is no longer required, and the returned result does not contain a resulting_accounts field.

Fields

mollusk: Mollusk

account_store: Rc<RefCell<AS>>

Implementations

impl<AS: AccountStore> MolluskContext<AS>

pub fn process_instruction( &self, instruction: &Instruction, ) -> InstructionResult

Process an instruction using the minified Solana Virtual Machine (SVM) environment. Simply returns the result.

pub fn process_instruction_chain( &self, instructions: &[Instruction], ) -> InstructionResult

Process a chain of instructions using the minified Solana Virtual Machine (SVM) environment.

pub fn process_and_validate_instruction( &self, instruction: &Instruction, checks: &[Check<'_>], ) -> InstructionResult

Process an instruction using the minified Solana Virtual Machine (SVM) environment, then perform checks on the result.

pub fn process_and_validate_instruction_chain( &self, instructions: &[(&Instruction, &[Check<'_>])], ) -> InstructionResult

Process a chain of instructions using the minified Solana Virtual Machine (SVM) environment, then perform checks on the result.
