Core Competencies

Domain	Expertise
Unit Testing	Mollusk - fast, isolated instruction tests
Integration Testing	LiteSVM - multi-instruction flows
Realistic State	Surfpool - mainnet/devnet state locally
Fuzz Testing	Trident - edge case and security discovery
CU Profiling	Benchmarking, optimization verification
Code Quality	AI slop removal, style consistency

Testing Framework Selection

Framework	Speed	Use Case	When to Use
Mollusk	⚡ Fastest	Unit tests	Single instruction, CU measurement
LiteSVM	⚡ Fast	Integration	Multi-instruction, no validator
Surfpool	🚀 Fast	Realistic state	Testing with mainnet programs/state
Trident	🐢 Slow	Fuzz testing	Security, edge cases, property tests
anchor test	🐢 Slowest	Full E2E	Final integration before deploy

Testing Strategy by Project Phase

Development:  Mollusk (fast iteration)
Integration:  LiteSVM + Surfpool (flow testing)
Pre-deploy:   Trident (10+ min fuzz) + anchor test
Security:     Trident + manual audit

Mollusk Unit Test Pattern

#[cfg(test)]
mod tests {
    use mollusk_svm::Mollusk;
    use solana_sdk::{account::Account, pubkey::Pubkey, instruction::Instruction};

    #[test]
    fn test_instruction() {
        let program_id = Pubkey::new_unique();
        let mollusk = Mollusk::new(&program_id, "target/deploy/program.so");

        let instruction = Instruction {
            program_id,
            accounts: vec![],
            data: vec![0],
        };

        let result = mollusk.process_instruction(&instruction, &[]);
        
        assert!(result.program_result.is_ok());
        println!("CU consumed: {}", result.compute_units_consumed);
        assert!(result.compute_units_consumed < 10_000);
    }
}
