Add comprehensive security tests for OWASP A03 (Injection) and A10 (SSRF)
- Implemented InjectionTests.cs to cover various injection vulnerabilities including SQL, NoSQL, Command, LDAP, and XPath injections. - Created SsrfTests.cs to test for Server-Side Request Forgery (SSRF) vulnerabilities, including internal URL access, cloud metadata access, and URL allowlist bypass attempts. - Introduced MaliciousPayloads.cs to store a collection of malicious payloads for testing various security vulnerabilities. - Added SecurityAssertions.cs for common security-specific assertion helpers. - Established SecurityTestBase.cs as a base class for security tests, providing common infrastructure and mocking utilities. - Configured the test project StellaOps.Security.Tests.csproj with necessary dependencies for testing.

# Mutation Testing Guide
|
||||
|
||||
This guide documents the integration and usage of Stryker.NET mutation testing in StellaOps.
|
||||
|
||||
## Overview
|
||||
|
||||
Mutation testing measures test suite effectiveness by introducing small code changes (mutants) and verifying that tests detect them. Unlike line coverage, mutation testing answers: **"Would my tests catch this bug?"**
|
||||
|
||||
## Installation
|
||||
|
||||
Stryker.NET is configured as a local dotnet tool:
|
||||
|
||||
```bash
|
||||
# Restore tools (includes Stryker.NET)
|
||||
dotnet tool restore
|
||||
|
||||
# Verify installation
|
||||
dotnet stryker --version
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Solution-Level Configuration
|
||||
|
||||
Base configuration is at `stryker-config.json` in the solution root. Module-specific configs override these settings.
|
||||
|
||||
### Module Configurations
|
||||
|
||||
| Module | Config Path | Mutation Break Threshold |
|
||||
|--------|-------------|-------------------------|
|
||||
| Scanner.Core | `src/Scanner/__Libraries/StellaOps.Scanner.Core/stryker-config.json` | 60% |
|
||||
| Policy.Engine | `src/Policy/StellaOps.Policy.Engine/stryker-config.json` | 60% |
|
||||
| Authority | `src/Authority/StellaOps.Authority/stryker-config.json` | 65% |
|
||||
|
||||
## Running Mutation Tests
|
||||
|
||||
### Single Module
|
||||
|
||||
```bash
|
||||
# Navigate to module directory
|
||||
cd src/Scanner/__Libraries/StellaOps.Scanner.Core
|
||||
|
||||
# Run mutation testing
|
||||
dotnet stryker
|
||||
|
||||
# With specific config
|
||||
dotnet stryker --config-file stryker-config.json
|
||||
```
|
||||
|
||||
### All Configured Modules
|
||||
|
||||
```bash
|
||||
# From solution root
|
||||
dotnet stryker --solution StellaOps.Router.slnx
|
||||
```
|
||||
|
||||
### CI Mode (Threshold Enforcement)
|
||||
|
||||
```bash
|
||||
# Fails if mutation score below threshold
|
||||
dotnet stryker --break-at-score 60
|
||||
```
|
||||
|
||||
## Understanding Results
|
||||
|
||||
### Mutation Score
|
||||
|
||||
```
|
||||
Mutation Score = (Killed Mutants / Total Mutants) × 100
|
||||
```
|
||||
|
||||
- **Killed**: Test failed when mutant was introduced (good!)
|
||||
- **Survived**: Test passed with mutant present (test gap!)
|
||||
- **No Coverage**: No test covered the mutated code
|
||||
- **Timeout**: Test timed out (usually treated as killed)
|
||||
|
||||
### Thresholds
|
||||
|
||||
| Level | Score | Meaning |
|
||||
|-------|-------|---------|
|
||||
| High | ≥80% | Excellent test effectiveness |
|
||||
| Low | ≥60% | Acceptable, improvements needed |
|
||||
| Break | <50% | Build fails, critical gaps |
|
||||
|
||||
### Example Output
|
||||
|
||||
```
|
||||
All mutants have been tested, and your mutation score has been calculated
|
||||
╔═══════════════════════════════════════════════════════════════════════╗

```
|
||||
|
||||
## Common Mutators
|
||||
|
||||
| Mutator | Original | Mutant |
|
||||
|---------|----------|--------|
|
||||
| Comparison | `>=` | `>` |
|
||||
| Equality | `==` | `!=` |
|
||||
| Boolean | `true` | `false` |
|
||||
| Logical | `&&` | `\|\|` |
|
||||
| Arithmetic | `+` | `-` |
|
||||
| NullCoalescing | `??` | ` ` (remove) |
|
||||
|
||||
## Fixing Survived Mutants
|
||||
|
||||
### 1. Analyze the Report
|
||||
|
||||
Open the HTML report in `.stryker/output/<module>/mutation-report.html`.
|
||||
|
||||
### 2. Identify the Gap
|
||||
|
||||
Look at the survived mutant:
|
||||
|
||||
```csharp
|
||||
// Original
|
||||
if (score >= threshold) { return "PASS"; }
|
||||
|
||||
// Mutant (survived!)
|
||||
if (score > threshold) { return "PASS"; }
|
||||
```
|
||||
|
||||
### 3. Add Missing Test
|
||||
|
||||
```csharp
|
||||
[Fact]
|
||||
public void Should_Pass_When_Score_Equals_Threshold()
|
||||
{
|
||||
var score = 60;
|
||||
var threshold = 60;
|
||||
|
||||
var result = EvaluateScore(score, threshold);
|
||||
|
||||
result.Should().Be("PASS"); // Now kills the >= to > mutant
|
||||
}
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Focus on Critical Modules First
|
||||
|
||||
Prioritize mutation testing for:
|
||||
- Security-critical code (Authority, Signer)
|
||||
- Business logic (Policy decisions, Scanner matching)
|
||||
- Boundary conditions
|
||||
|
||||
### 2. Don't Chase 100%
|
||||
|
||||
Some mutants are false positives or equivalent mutants. Aim for 80%+ on critical modules.
|
||||
|
||||
### 3. Use Baseline Mode
|
||||
|
||||
Enable baseline to only test changed files:
|
||||
|
||||
```bash
|
||||
dotnet stryker --with-baseline:main
|
||||
```
|
||||
|
||||
### 4. Exclude Non-Critical Code
|
||||
|
||||
Exclude from mutation testing:
|
||||
- DTOs and models
|
||||
- Generated code
|
||||
- Migrations
|
||||
- UI components
|
||||
|
||||
## CI Integration
|
||||
|
||||
Mutation testing runs in CI:
|
||||
|
||||
```yaml
|
||||
mutation-test:
|
||||
runs-on: ubuntu-latest
|
||||
steps:
|
||||
- uses: actions/checkout@v4
|
||||
- name: Run Stryker
|
||||
run: |
|
||||
dotnet tool restore
|
||||
dotnet stryker --break-at-score 60
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Slow Execution
|
||||
|
||||
- Use `--concurrency` to control parallelism
|
||||
- Enable `coverage-analysis: perTest` for smarter mutant selection
|
||||
- Use `--since:main` to only test changed code
|
||||
|
||||
### Out of Memory
|
||||
|
||||
- Reduce `--concurrency` value
|
||||
- Exclude large test projects
|
||||
|
||||
### Timeout Issues
|
||||
|
||||
- Adjust `--timeout` setting
|
||||
- Some infinite loop mutants may timeout (this is expected)

# SCA Failure Catalogue Fixtures (Placeholder)

# SCA Failure Catalogue Fixtures
|
||||
|
||||
This directory hosts deterministic fixtures for the five regressions in
|
||||
`docs/product-advisories/29-Nov-2025 - SCA Failure Catalogue for StellaOps Tests.md`.
|
||||
This directory hosts deterministic fixtures for scanner failure mode regression testing.
|
||||
Each fixture documents a real-world failure pattern that StellaOps must handle correctly.
|
||||
|
||||
Cases (to be populated):
|
||||
- FC1 credential leak (Grype)
|
||||
- FC2 Trivy offline DB schema mismatch
|
||||
- FC3 SBOM parity drift
|
||||
- FC4 Grype version divergence
|
||||
- FC5 inconsistent detection
|
||||
## Catalogue Overview
|
||||
|
||||
| ID | Name | Failure Mode | Added |
|
||||
|----|------|--------------|-------|
|
||||
| FC1 | Credential Leak | Grype credential leak in environment | 2025-11-30 |
|
||||
| FC2 | Trivy DB Schema | Trivy offline DB schema mismatch | 2025-11-30 |
|
||||
| FC3 | SBOM Parity | SBOM parity drift between tools | 2025-11-30 |
|
||||
| FC4 | Grype Version | Grype version divergence | 2025-11-30 |
|
||||
| FC5 | Inconsistent Detection | Inconsistent detection across runs | 2025-11-30 |
|
||||
| FC6 | Java Shadow JAR | Fat/uber JARs with shaded dependencies | 2025-12-16 |
|
||||
| FC7 | .NET Transitive Pinning | Transitive dependency version conflicts | 2025-12-16 |
|
||||
| FC8 | Docker Multi-Stage Leakage | Build-time deps leaking into runtime | 2025-12-16 |
|
||||
| FC9 | PURL Namespace Collision | Same package name in different ecosystems | 2025-12-16 |
|
||||
| FC10 | CVE Split/Merge | CVE split/merge tracking issues | 2025-12-16 |
|
||||
|
||||
## Fixture Structure
|
||||
|
||||
Each fixture directory (`fc1/`, `fc2/`, etc.) contains:
|
||||
|
||||
- `expected.json` - Expected scanner output and test assertions
|
||||
- `input.txt` - Input description and configuration
|
||||
- `manifest.dsse.json` - DSSE-signed manifest for integrity verification
|
||||
|
||||
## Usage
|
||||
|
||||
```bash
|
||||
# Run all catalogue tests
|
||||
dotnet test --filter "Category=ScaCatalogue"
|
||||
|
||||
# Run specific fixture
|
||||
dotnet test --filter "FullyQualifiedName~FC6"
|
||||
```
|
||||
|
||||
## Constraints
|
||||
|
||||
- All fixtures are deterministic and offline-capable
|
||||
- Pinned tool versions and feeds are recorded in `inputs.lock`
|
||||
- No network access; rely on bundled caches only
|
||||
- All outputs must be normalized before comparison
|
||||
|
||||
- Pinned tool versions and feeds are recorded in `inputs.lock`.
|
||||
- Each case will include DSSE-signed manifests and normalized expected outputs.
|
||||
- No network access; rely on bundled caches only.

# Security Testing Framework
|
||||
|
||||
This directory contains systematic security tests covering OWASP Top 10 vulnerabilities for StellaOps modules.
|
||||
|
||||
## Structure
|
||||
|
||||
```
|
||||
security/
|
||||
├── StellaOps.Security.Tests/
|
||||
│ ├── Infrastructure/ # Base classes and test utilities
|

## OWASP Top 10 Coverage
|
||||
|
||||
| Rank | Category | Priority | Status |
|
||||
|------|----------|----------|--------|
|
||||
| A01 | Broken Access Control | CRITICAL | ✓ |
|
||||
| A02 | Cryptographic Failures | CRITICAL | ✓ |
|
||||
| A03 | Injection | CRITICAL | ✓ |
|
||||
| A05 | Security Misconfiguration | HIGH | ✓ |
|
||||
| A07 | Authentication Failures | CRITICAL | ✓ |
|
||||
| A08 | Integrity Failures | HIGH | ✓ |
|
||||
| A10 | SSRF | HIGH | ✓ |
|
||||
|
||||
## Running Tests
|
||||
|
||||
```bash
|
||||
# Run all security tests
|
||||
dotnet test tests/security/StellaOps.Security.Tests --filter "Category=Security"
|
||||
|
||||
# Run specific OWASP category
|
||||
dotnet test --filter "FullyQualifiedName~A01_BrokenAccessControl"
|
||||
|
||||
# Run with detailed output
|
||||
dotnet test tests/security/StellaOps.Security.Tests -v normal
|
||||
```
|
||||
|
||||
## Adding New Tests
|
||||
|
||||
1. Create test class in appropriate category directory
|
||||
2. Inherit from `SecurityTestBase`
|
||||
3. Use `MaliciousPayloads` for injection payloads
|
||||
4. Use `SecurityAssertions` for security-specific assertions
|
||||
|
||||
## CI Integration
|
||||
|
||||
Security tests run as part of the CI pipeline:
|
||||
- All PRs: Run critical security tests (A01, A02, A03, A07)
|
||||
- Nightly: Full OWASP Top 10 coverage
|
||||
- Pre-release: Full suite with extended fuzzing
