Testing and W3C Suite

Svg.Skia uses several layers of verification.

Unit tests

The tests/ folder covers:

runtime renderer behavior,
hit testing,
picture rebuild behavior,
font and typeface selection,
Avalonia integration,
VectorDrawable parsing and validation.

W3C SVG 1.1 suite

The repository includes the W3C SVG 1.1 test-suite assets as a submodule under externals/W3C_SVG_11_TestSuite.

tests/Svg.Skia.UnitTests/W3CTestSuiteTests.cs compares rendered output against the expected PNG baselines for the supported subset.

UI tests

Avalonia-related packages are also covered with UI-oriented tests where appropriate, including the Avalonia.Svg.Skia.UiTests project in the solution.

Source-generator stress scripts

The tests-sourcegenerators/ folder contains scripts that exercise generated-code workflows against larger input sets:

W3CTestSuite.sh
fluentui-system-icons.sh
resvg-test-suite.sh

These scripts clone external repositories, run svgc, create console projects, add SkiaSharp dependencies, and validate that the generated code compiles.

Why this matters

This repository does more than simple bitmap conversion. It spans:

document parsing,
model conversion,
runtime rendering,
Avalonia integration,
generated code,
Android VectorDrawable import.

The layered test strategy reflects that larger surface area.
