## Testing Checklist
### Basic Functionality Tests
#### Test 1: `@secure` Authentication
```dal
@secure
service TestService {
fn test_method() {
// Should require current_caller to be set
}
}
```
**Expected**: ✅ Blocks if `current_caller` not set
#### Test 2: `@secure` Reentrancy Protection
```dal
@secure
service TestService {
fn test_method() {
self.test_method(); // Should fail - reentrancy detected
}
}
```
**Expected**: ✅ Blocks re-entry into same method
#### Test 2b: Function-Level `@secure`
```dal
service TestService {
fn public_method() {
// No @secure - public access
}
@secure
fn secure_method() {
// Requires authentication
}
}
```
**Expected**: ✅ Function-level `@secure` enforced independently
#### Test 2c: Function-Level Override
```dal
@secure // Service-level: all methods secure by default
service TestService {
fn secure_method() {
// ✅ Inherits @secure from service
}
@public
fn public_method() {
// ✅ Function-level @public overrides service @secure
}
}
```
**Expected**: ✅ Function-level attributes override service-level
#### Test 3: `@advanced_security` Monitoring Code
```dal
@advanced_security
service TestService {
fn find_opportunities() {
// Should be allowed
}
}
```
**Expected**: ✅ Executes successfully
#### Test 4: `@advanced_security` Protected Execution
```dal
@advanced_security
service TestService {
fn execute_protected_swap() {
let commitment_hash = crypto::hash(...); // Protection
let min_amount_out = ...; // Protection
// Should be allowed
}
}
```
**Expected**: ✅ Executes successfully
#### Test 5: `@advanced_security` Unprotected Execution
```dal
@advanced_security
service TestService {
fn execute_swap() {
// No protection patterns
// Should be blocked
}
}
```
**Expected**: ❌ Blocked with helpful error message
---
## Known Limitations
### 1. MEV Detection Scope
- ⚠️ **Scans entire program AST** - May be slow for large programs
- **Future**: Could optimize to scan only execution paths
- **Status**: Works but could be optimized
### 3. Protection Pattern Detection
- ⚠️ **String-based matching** - May have false positives/negatives
- **Future**: Could use AST analysis for more accurate detection
- **Status**: Works for common patterns
---
## Developer Usage Guide
### Quick Start
#### 1. Basic Secure Service
```dal
@secure
service MyService {
fn protected_method() {
// Automatically protected:
// - Authentication required
// - Reentrancy protection
// - Audit logging
}
}
```
#### 1b. Function-Level Secure Service
```dal
service MyService {
fn public_read() {
// ✅ Public access (no @secure)
}
@secure
fn secure_write() {
// ✅ Requires authentication
// ✅ Reentrancy protection
// ✅ Audit logging
}
}
```
#### 1c. Mixed Security with Inheritance
```dal
@secure // All methods secure by default
service MyService {
fn secure_method() {
// ✅ Inherits @secure from service
}
@public
fn public_method() {
// ✅ Function-level @public overrides service @secure
}
@secure
fn explicitly_secure() {
// ✅ Explicit function-level (same as inheriting)
}
}
```
#### 2. MEV-Protected DeFi Service
```dal
@secure
@advanced_security
service DeFiService {
// Monitoring (always allowed)
fn find_price_differences() {
// ✅ Allowed
}
// Protected execution (allowed)
fn execute_protected_swap(...) {
let commitment_hash = crypto::hash(...); // Protection ✓
let min_amount_out = ...; // Protection ✓
// ✅ Allowed
}
// Unprotected execution (blocked)
fn execute_unprotected_swap(...) {
// ❌ Blocked: "Consider adding protection patterns"
}
}
```
#### 3. Manual MEV Protection (No Attributes)
```dal
service DeFiService {
fn execute_swap(...) {
// Manual protection patterns (see MEV_PROTECTION_MANUAL.md)
let commitment_hash = crypto::hash(...);
let min_amount_out = ...;
// Works without @advanced_security
}
}
```
