From a5971f1398ba7f9abb6d89263dc7925362146bee Mon Sep 17 00:00:00 2001 From: Your Name Date: Thu, 8 Jan 2026 19:41:15 +1300 Subject: [PATCH 01/12] =?UTF-8?q?=EF=BB=BFPHASE=203=20COMPLETE:=20Client?= =?UTF-8?q?=20Core=20Simulation=20&=20Test=20Quality=20Improvements?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Step 3.1: Client Simulation Loop - Implemented deterministic client fixed-step simulation with accumulator (60Hz) and spiral guard (MAX_TICKS_PER_FRAME = 10). - Fixed accumulator edge-case: compute whole ticks via floor+EPS and snap tiny residuals to zero to avoid one-tick loss during backlog processing. - Preserve residual accumulator after clamping (backlog processed on subsequent frames). - Added zero-allocation hot-path patterns (InputBatch reuse, pre-allocated RingBuffer access). Step 3.2: Test Quality & Negative Tests - Added dedicated negative tests file: Assets/Tests/Editor/Phase3EditModeNegativeTests.cs (spiral/backlog boundary test). - Added Phase 1 & Phase 2 negative test suites: Phase1EditModeNegativeTests.cs, Phase2EditModeNegativeTests.cs (ghost-data, wrap handling, numeric stability, field preservation). - Moved negative tests out of positive suite and documented them in AgenticDevelopment/TEST_REGISTRY.md. - Added naming convention note for negative/boundary tests to AgenticDevelopment/.cursorrules. Step 3.3: Docs & Standards - Updated AgenticDevelopment/TEST_REGISTRY.md and .cursorrules to reflect test organization and naming conventions. - Added comments in Phase3EditModeTests.cs pointing to negative tests file. Testing & Validation - EditMode tests: 26/26 passing locally (Phase 1–3 positive + negative suites). - Zero-GC per-tick test passed (Editor-only profiler check). - No compile errors or warnings observed. Performance - Hot-path changes preserve zero-alloc expectations (InputBatch reuse, pre-sized RingBuffer and lists). Notes / Next Steps - Ready to commit and push. CI run on GitHub Actions requires the UNITY_LICENSE repo secret for Unity activation — ensure it is present before pushing to trigger full CI. - Recommend pushing to a feature branch, then opening PR for final review & CI validation. CHECKPOINT 3: All Phase 3 acceptance criteria met. Ready for push CI merge. --- .github/workflows/unity-tests.yml | 79 ++++++++ Assets/Scripts/Entities/ClientEntity.cs | 170 ++++++++++++++++++ Assets/Scripts/Entities/ClientEntity.cs.meta | 2 + .../Scripts/Entities/ClientEntityBehaviour.cs | 61 +++++++ .../Entities/ClientEntityBehaviour.cs.meta | 2 + .../DeterministicRollback.EditorTests.asmdef | 3 +- .../Editor/Phase1EditModeNegativeTests.cs | 42 +++++ .../Phase1EditModeNegativeTests.cs.meta | 2 + ...{Phase1Tests.cs => Phase1EditModeTests.cs} | 2 +- .../Tests/Editor/Phase1EditModeTests.cs.meta | 2 + Assets/Tests/Editor/Phase1Tests.cs.meta | 2 - .../Editor/Phase2EditModeNegativeTests.cs | 39 ++++ .../Phase2EditModeNegativeTests.cs.meta | 2 + .../Editor/Phase3EditModeNegativeTests.cs | 55 ++++++ .../Phase3EditModeNegativeTests.cs.meta | 2 + Assets/Tests/Editor/Phase3EditModeTests.cs | 108 +++++++++++ .../Tests/Editor/Phase3EditModeTests.cs.meta | 2 + Packages/manifest.json | 3 + Packages/packages-lock.json | 121 +++++++++++++ ProjectSettings/EditorBuildSettings.asset | 3 +- ProjectSettings/ProjectSettings.asset | 13 +- 21 files changed, 704 insertions(+), 11 deletions(-) create mode 100644 .github/workflows/unity-tests.yml create mode 100644 Assets/Scripts/Entities/ClientEntity.cs create mode 100644 Assets/Scripts/Entities/ClientEntity.cs.meta create mode 100644 Assets/Scripts/Entities/ClientEntityBehaviour.cs create mode 100644 Assets/Scripts/Entities/ClientEntityBehaviour.cs.meta create mode 100644 Assets/Tests/Editor/Phase1EditModeNegativeTests.cs create mode 100644 Assets/Tests/Editor/Phase1EditModeNegativeTests.cs.meta rename Assets/Tests/Editor/{Phase1Tests.cs => Phase1EditModeTests.cs} (99%) create mode 100644 Assets/Tests/Editor/Phase1EditModeTests.cs.meta delete mode 100644 Assets/Tests/Editor/Phase1Tests.cs.meta create mode 100644 Assets/Tests/Editor/Phase2EditModeNegativeTests.cs create mode 100644 Assets/Tests/Editor/Phase2EditModeNegativeTests.cs.meta create mode 100644 Assets/Tests/Editor/Phase3EditModeNegativeTests.cs create mode 100644 Assets/Tests/Editor/Phase3EditModeNegativeTests.cs.meta create mode 100644 Assets/Tests/Editor/Phase3EditModeTests.cs create mode 100644 Assets/Tests/Editor/Phase3EditModeTests.cs.meta diff --git a/.github/workflows/unity-tests.yml b/.github/workflows/unity-tests.yml new file mode 100644 index 0000000..5aa0386 --- /dev/null +++ b/.github/workflows/unity-tests.yml @@ -0,0 +1,79 @@ +name: Unity Tests + +on: + push: + branches: [ main, develop, feature/** ] + pull_request: + branches: [ main, develop ] + +jobs: + test: + name: Run Unity Tests + runs-on: ubuntu-latest + + steps: + # Checkout repository + - name: Checkout repository + uses: actions/checkout@v4 + with: + lfs: true + + # Cache Unity Library folder + - name: Cache Unity Library + uses: actions/cache@v3 + with: + path: Library + key: Library-${{ hashFiles('Assets/**', 'Packages/**', 'ProjectSettings/**') }} + restore-keys: | + Library- + + # Run EditMode tests + - name: Run EditMode Tests + uses: game-ci/unity-test-runner@v4 + id: editmode-tests + env: + UNITY_LICENSE: ${{ secrets.UNITY_LICENSE }} + with: + projectPath: . + testMode: EditMode + artifactsPath: test-results/editmode + githubToken: ${{ secrets.GITHUB_TOKEN }} + checkName: EditMode Test Results + + # Run PlayMode tests + - name: Run PlayMode Tests + uses: game-ci/unity-test-runner@v4 + id: playmode-tests + env: + UNITY_LICENSE: ${{ secrets.UNITY_LICENSE }} + with: + projectPath: . + testMode: PlayMode + artifactsPath: test-results/playmode + githubToken: ${{ secrets.GITHUB_TOKEN }} + checkName: PlayMode Test Results + + # Upload test results as artifacts + - name: Upload EditMode Test Results + if: always() + uses: actions/upload-artifact@v3 + with: + name: EditMode-Test-Results + path: test-results/editmode + + - name: Upload PlayMode Test Results + if: always() + uses: actions/upload-artifact@v3 + with: + name: PlayMode-Test-Results + path: test-results/playmode + + # Report test results in PR + - name: Comment Test Results on PR + if: github.event_name == 'pull_request' && always() + uses: dorny/test-reporter@v1 + with: + name: Unity Test Results + path: 'test-results/**/*.xml' + reporter: java-junit + fail-on-error: true diff --git a/Assets/Scripts/Entities/ClientEntity.cs b/Assets/Scripts/Entities/ClientEntity.cs new file mode 100644 index 0000000..e397664 --- /dev/null +++ b/Assets/Scripts/Entities/ClientEntity.cs @@ -0,0 +1,170 @@ +using System; +using UnityEngine; +using DeterministicRollback.Core; +using DeterministicRollback.Networking; + +namespace DeterministicRollback.Entities +{ + /// + /// Non-Mono-client simulation core.
