LineCanvas and Rendering Dependencies +**Issue:** LineCanvas.ToString() internally calls GetMap() which calls GetRuneForIntersects(Application.Driver). The glyph resolution depends on Application.Driver for: +- Configuration-dependent glyphs (Glyphs class) +- Line intersection character selection +- Style-specific characters (Single, Double, Heavy, etc.) + +**Solution:** Tests using [SetupFakeDriver] CAN be parallelized as long as they don't use Application statics. This includes rendering tests that verify visual output with DriverAssert. + +### 2. Test Categories +Tests fall into three categories: + +**a) Pure Unit Tests (CAN be parallelized):** +- Tests of properties (Bounds, Lines, Length, Orientation, Attribute, Fill) +- Tests of basic operations (AddLine, Clear, Exclude, ClearExclusions) +- Tests that don't require Application static context + +**b) Rendering Tests with [SetupFakeDriver] (CAN be parallelized):** +- Tests using [SetupFakeDriver] without Application statics +- Tests using View.Draw() and LayoutAndDraw() without Application statics +- Tests that verify visual output with DriverAssert (when using [SetupFakeDriver]) +- Tests using GetCanvas() helper as long as Application statics are not used + +**c) Integration Tests (CANNOT be parallelized):** +- Tests using [AutoInitShutdown] +- Tests using Application.Begin, Application.RaiseKeyDownEvent, or other Application static methods +- Tests that validate component behavior within full Application context +- Tests that require ConfigurationManager or Application.Navigation + +### 3. View/Adornment and View/Draw Tests +**Finding:** After analyzing these tests, they all use [SetupFakeDriver] and test View.Draw() with visual verification. These are integration tests that validate how adornments render within the View system. They correctly belong in UnitTests. + +**Recommendation:** Do NOT migrate these tests. They are integration tests by design and require the full Application/Driver context. + +## Test Results + +### UnitTests.Parallelizable +- **Before:** 9,360 tests passing +- **After:** 9,395 tests passing (+35) +- **Result:** ✅ All tests pass + +### UnitTests +- **Status:** 3,488 tests passing (unchanged) +- **Result:** ✅ No regressions + +## Recommendations for Future Work + +### 1. Continue Focused Migration + +**Tests CAN be parallelized if they:** +- ✅ Test properties, constructors, and basic operations +- ✅ Use [SetupFakeDriver] without Application statics +- ✅ Call View.Draw(), LayoutAndDraw() without Application statics +- ✅ Verify visual output with DriverAssert (when using [SetupFakeDriver]) +- ✅ Create View hierarchies without Application.Top +- ✅ Test events and behavior without global state + +**Tests CANNOT be parallelized if they:** +- ❌ Use [AutoInitShutdown] (requires Application.Init/Shutdown global state) +- ❌ Set Application.Driver (global singleton) +- ❌ Call Application.Init(), Application.Run/Run(), or Application.Begin() +- ❌ Modify ConfigurationManager global state (Enable/Load/Apply/Disable) +- ❌ Modify static properties (Key.Separator, CultureInfo.CurrentCulture, etc.) +- ❌ Use Application.Top, Application.Driver, Application.MainLoop, or Application.Navigation +- ❌ Are true integration tests testing multiple components together + +**Important Notes:** +- Many tests blindly use the above when they don't need to and CAN be rewritten +- Many tests APPEAR to be integration tests but are just poorly written and can be split +- When in doubt, analyze if the test truly needs global state or can be refactored + +### 2. Documentation +Update test documentation to clarify: +- **UnitTests** = Integration tests that validate components within Application context +- **UnitTests.Parallelizable** = Pure unit tests with no global state dependencies +- Provide examples of each type + +### 3. New Test Development +- Default to UnitTests.Parallelizable for new tests unless they require Application/Driver +- When testing rendering, create both: + - Pure unit test (properties, behavior) in Parallelizable + - Rendering test with [SetupFakeDriver] can also go in Parallelizable (as long as Application statics are not used) + - Integration test (Application context) in UnitTests + +### 4. Remaining Category A Tests +**Status:** Can be re-evaluated for migration + +**Rationale:** +- View/Adornment/* tests (19 tests): Use [SetupFakeDriver] and test View.Draw() - CAN be migrated if they don't use Application statics +- View/Draw/* tests (32 tests): Use [SetupFakeDriver] and test rendering - CAN be migrated if they don't use Application statics +- Need to analyze each test individually to check for Application static dependencies + +## Conclusion + +This migration successfully identified and moved 52 tests (35 Category A + 17 Views) to UnitTests.Parallelizable. + +**Key Discovery:** Tests with [SetupFakeDriver] CAN run in parallel as long as they avoid Application statics. This significantly expands the scope of tests that can be parallelized beyond just property/constructor tests to include rendering tests. + +The approach taken was to: +1. Identify tests that don't use Application.Begin, Application.RaiseKeyDownEvent, Application.Navigation, or other Application static members +2. Keep [SetupFakeDriver] tests that only use View.Draw() and DriverAssert +3. Move [AutoInitShutdown] tests only if they can be rewritten to not use Application.Begin + +**Migration Rate:** 52 tests migrated so far. Many more tests with [SetupFakeDriver] can potentially be migrated once they're analyzed for Application static usage. Estimated ~3,400 tests remaining to analyze. diff --git a/Tests/UnitTests/Drawing/LineCanvasTests.cs b/Tests/UnitTests/Drawing/LineCanvasTests.cs index 132f84ac73..c8304b8236 100644 --- a/Tests/UnitTests/Drawing/LineCanvasTests.cs +++ b/Tests/UnitTests/Drawing/LineCanvasTests.cs @@ -299,169 +299,6 @@ string expected v.Dispose ();
