C# Testing Skill
You are a C# Testing specialist. Use this skill to design, write, and execute tests for the V12 Universal OR Strategy.
I. Testing Frameworks
- Primary: XUnit or NUnit for logic testing.
- Mocking: Moq for IPC and Account API abstraction.
- Performance: BenchmarkDotNet for hot-path latency and allocation auditing.
II. NinjaTrader 8 Compatibility
- Constraint: NT8 runs on .NET Framework 4.8. Avoid modern .NET Core/5/6+ features in test projects that need to reference NT8 DLLs.
- Abstraction: Wrap NT8-specific objects (Instrument, Account) in interfaces for unit testing.
III. V12 Standard Testing Patterns
- State Machine Verification: Test FSM transitions (e.g.,
PendingCancel -> CancelConfirmed) using event-based assertion.
- Lock-Free Audit: Verify concurrent safety of SPSC/MPMC queues without using
lock.
- Zero-Allocation: Use the
amal_harness.py logic to verify that hot-path methods (e.g., ManageTrailingStops) perform zero Gen0/Gen1 allocations.
- IPC Round-Trip: Test JSON command serialization/deserialization across the TCP boundary.
IV. Commands
- Run Unit Tests:
dotnet test
- Run Benchmarks:
dotnet run -c Release --project Benchmarks.csproj
- Stress Test:
powershell -File scripts/test_stress.ps1
When to use this skill
- Before any P5 Implementation (TDD).
- During P6 Validation to verify bug fixes.
- When refactoring high-complexity methods to ensure no logic regression.
Mandatory Post-Use Self-Improvement Audit (NON-NEGOTIABLE)
After completing any session using this skill, perform an audit:
- Did any instruction produce an unexpected result or confusion?
- Was any rule ambiguous enough that you had to make a judgment call?
- Was a step missing that caused backtracking?
- Is any reference file out of date?
If yes to any: update this SKILL.md or references/ file immediately, then commit:
skill(csharp-testing): [what was fixed]
If no gaps found: state skill(csharp-testing): no gaps identified. in your response.
No Director approval required for skill-only edits.
