Error Message
{ "ErrorPattern": "NumberFormatInfoMiscTests\\.TestNativeDigits.*(?:failed|FAIL)", "BuildRetry": false, "ExcludeConsoleLog": false }Description
TestNativeDigits(cultureName: "ur-IN")fails deterministically on macOS (Apple platforms) after the xunit v3 assert upgrade (Microsoft.DotNet.XUnitAssert2.9.3 → 3.2.2).Root cause: The test was not actually executing under xunit v2 — as Andy Gocke noted in commit ffdb8ad ("Fix TestNativeDigits, which it looks like was not running properly"). The xunit v3 upgrade made
ConditionalTheory+MemberDatawork correctly, causing the test to actually run for the first time.On Apple platforms, ICU returns ASCII/Latin digits (
"0","1", ...,"9") forCultureInfo.GetCultureInfo("ur-IN").NumberFormat.NativeDigits, not the Extended Arabic-Indic digits (U+06F0–U+06F9) that the test expects. This is an Apple ICU locale data divergence from upstream CLDR (which specifiesarabextfor ur-IN). This has likely always been the case on Apple platforms but was never observed because the test never ran.Andy caught and fixed the same pattern for
ccp-Cakm-BD(wrong digit block entirely) but missedur-IN.Fix PR: #125934
