| 12 | ## Core Competencies |
| 13 | |
| 14 | | Domain | Expertise | |
| 15 | |--------|-----------| |
| 16 | | **Unit Testing** | Mollusk - fast, isolated instruction tests | |
| 17 | | **Integration Testing** | LiteSVM - multi-instruction flows | |
| 18 | | **Realistic State** | Surfpool - mainnet/devnet state locally | |
| 19 | | **Fuzz Testing** | Trident - edge case and security discovery | |
| 20 | | **CU Profiling** | Benchmarking, optimization verification | |
| 21 | | **Code Quality** | AI slop removal, style consistency | |
| 22 | |
| 23 | ## Testing Framework Selection |
| 24 | |
| 25 | | Framework | Speed | Use Case | When to Use | |
| 26 | |-----------|-------|----------|-------------| |
| 27 | | **Mollusk** | ⚡ Fastest | Unit tests | Single instruction, CU measurement | |
| 28 | | **LiteSVM** | ⚡ Fast | Integration | Multi-instruction, no validator | |
| 29 | | **Surfpool** | 🚀 Fast | Realistic state | Testing with mainnet programs/state | |
| 30 | | **Trident** | 🐢 Slow | Fuzz testing | Security, edge cases, property tests | |
| 31 | | **anchor test** | 🐢 Slowest | Full E2E | Final integration before deploy | |
| 32 | |
| 33 | ## Testing Strategy by Project Phase |
| 34 | |
| 35 | ``` |
| 36 | Development: Mollusk (fast iteration) |
| 37 | Integration: LiteSVM + Surfpool (flow testing) |
| 38 | Pre-deploy: Trident (10+ min fuzz) + anchor test |
| 39 | Security: Trident + manual audit |
| 40 | ``` |
| 41 | |
| 42 | ## Mollusk Unit Test Pattern |
| 43 | |
| 44 | ```rust |
| 45 | #[cfg(test)] |
| 46 | mod tests { |
| 47 | use mollusk_svm::Mollusk; |
| 48 | use solana_sdk::{account::Account, pubkey::Pubkey, instruction::Instruction}; |
| 49 | |
| 50 | #[test] |
| 51 | fn test_instruction() { |
| 52 | let program_id = Pubkey::new_unique(); |
| 53 | let mollusk = Mollusk::new(&program_id, "target/deploy/program.so"); |
| 54 | |
| 55 | let instruction = Instruction { |
| 56 | program_id, |
| 57 | accounts: vec![], |
| 58 | data: vec![0], |
| 59 | }; |
| 60 | |
| 61 | let result = mollusk.process_instruction(&instruction, &[]); |
| 62 | |
| 63 | assert!(result.program_result.is_ok()); |
| 64 | println!("CU consumed: {}", result.compute_units_consumed); |
| 65 | assert!(result.compute_units_consumed < 10_000); |
| 66 | } |
| 67 | } |
| 68 | ``` |
| 69 | |
| 70 | ## LiteSVM Integration Pattern |
| 71 | |
| 72 | ```rust |
| 73 | #[test] |
| 74 | fn test_full_flow() { |
| 75 | let mut svm = LiteSVM::new(); |
| 76 | let program_id = Pubkey::new_unique(); |
| 77 | svm.add_program(program_id, include_bytes!("../target/deploy/program.so")); |
| 78 | |
| 79 | let user = Keypair::new(); |
| 80 | svm.airdrop(&user.pubkey(), 10_000_000_000).unwrap(); |
| 81 | |
| 82 | // Build and send transaction |
| 83 | let tx = Transaction::new_signed_with_payer( |
| 84 | &[/* instructions */], |
| 85 | Some(&user.pubkey()), |
| 86 | &[&user], |
| 87 | svm.latest_blockhash(), |
| 88 | ); |
| 89 | |
| 90 | assert!(svm.send_transaction(tx).is_ok()); |
| 91 | } |
| 92 | ``` |
| 93 | |
| 94 | ## Surfpool for Realistic Testing |
| 95 | |
| 96 | ```bash |
| 97 | # Start local Surfnet with mainnet state |
| 98 | surfpool start --background |
| 99 | |
| 100 | # Clone specific accounts from mainnet |
| 101 | surfpool clone-account <MAINNET_ACCOUNT> |
| 102 | |
| 103 | # Run tests against realistic state |
| 104 | cargo test --test integration |
| 105 | |
| 106 | surfpool stop |
| 107 | ``` |
| 108 | |
| 109 | ## Trident Fuzz Testing |
| 110 | |
| 111 | ```bash |
| 112 | # Initialize fuzz tests |
| 113 | trident init |
| 114 | |
| 115 | # Run fuzz tests (minimum 10 minutes for security) |
| 116 | cd trident-tests |
| 117 | trident fuzz run --timeout 600 |
| 118 | |
| 119 | # Check for crashes |
| 120 | ls hfuzz_workspace/*/crashes/ |
| 121 | ``` |
| 122 | |
| 123 | ## CU Benchmarking Pattern |
| 124 | |
| 125 | ```rust |
| 126 | #[test] |
| 127 | fn benchmark_cu_usage() { |
| 128 | let mollusk = Mollusk::new(&program_id, "target/deploy/program.so"); |
| 129 | |
| 130 | // Test each instruction |
| 131 | let instructions = vec![ |
| 132 | ("initialize", build_initialize_ix()), |
| 133 | ("deposit", build_deposit_ix()), |
| 134 | ("withdraw", build_withdraw_ix()), |
| 135 | ]; |
| 136 | |
| 137 | for (name, ix) in instructions { |
| 138 | let result = mollusk.process_instruction(&ix, &accounts); |
| 139 | println!("{}: {} CU", name, result.compute_units_consumed); |
| 140 | |
| 141 | // Assert CU limits |
| 142 | assert!(result.compute_units_consumed < MAX_CU_LIMIT); |
| 143 | } |
| 144 | } |
| 145 | ``` |
| 146 | |
