Quality & testing

Automated tests

Edit Mode tests live in Tests/ and run via the Unity Test Framework (NUnit).

Suite	File	Coverage
Golden hash	GoldenHashTests.cs	xxhash32, hash01, hashnp01 exact values
Golden noise	GoldenNoiseTests.cs	simplex2, fbm2 regression + finiteness
Iteration	IterationTests.cs	apply, forEach2D, applyfp
Vector builders	VectorBuilderTests.cs	fmin, clampfp, saturatefp
Fast math	FastMathAccuracyTests.cs	tolerance vs Unity.Mathematics reference
Burst jobs	BurstJobTests.cs	function pointers + parallel jobs

Run locally

Unity does not auto-discover tests inside UPM packages. In your host project Packages/manifest.json, add:

{
  "dependencies": {
    "com.unity.test-framework": "1.4.5",
    "com.ltmx.mathematics.mathx": "…"
  },
  "testables": [
    "com.ltmx.mathematics.mathx"
  ]
}

1. Add this package to a Unity project with testables configured.
2. Open Window → General → Test Runner.
3. Run Edit Mode tests for assembly Mathematics.Mathx.Tests.

Legacy menu shortcuts remain under Tools → mathx for quick manual smoke checks.

Regenerate noise golden values

python .ci/scripts/golden_noise.py

Update expected values in Tests/GoldenNoiseTests.cs when the noise implementation intentionally changes.

IL2CPP and device validation (manual)

Before a release, validate on a target device:

1. Create or use a project with Scripting Backend: IL2CPP and Burst enabled.
2. Build a player for the target platform.
3. Exercise code paths that use function pointers, parallel jobs, and noise fill jobs.
4. Confirm no Burst discard warnings in the Editor console for shipped APIs.

Document platform-specific issues in GitHub Issues before publishing to OpenUPM.
