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 \|

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
147	## Code Quality Standards
148
149	### AI Slop Detection and Removal
150
151	After completing work, check the diff against main:
152
153	```bash
154	git diff main...HEAD
155	```
156
157	Remove these patterns:
