Pull Request Overview
This PR adds a targeted Helix job that only runs template tests when files under src/ProjectTemplates change, and updates existing CI pipelines to skip those tests by default.
- Introduces
OnlyTestProjectTemplatesMSBuild property and uses it to filter which projects are built/tested. - Adds a new Azure pipeline (
template-tests-pr.yml) triggered on template folder changes. - Updates
ci.ymlandci-public.ymlto disable template tests by settingRunTemplateTests=false.

- The
-noblflag was removed here, which changes the build invocation from the original. You should include-noblto preserve the intended behavior.
- script: ./eng/build.cmd -ci -prepareMachine -nativeToolsOnMachine -all -noBuildRepoTasks -noBuildNative -noBuild -test
.azure/pipelines/ci-public.yml:585
- The
-noblflag was removed here as well, unintentionally altering the build behavior. Please restore-noblto match the original invocation.
- script: ./eng/build.cmd -ci -prepareMachine -nativeToolsOnMachine -all -noBuildRepoTasks -noBuildNative -noBuild -test
.azure/pipelines/ci.yml:639
- You’re setting
RunTemplateTests=falsebut the code usesOnlyTestProjectTemplatesto gate template test execution. Rename or duplicate this property so the MSBuild condition works correctly.
/p:CrossgenOutput=false /p:RunTemplateTests=false /p:ASPNETCORE_TEST_LOG_DIR=artifacts/log $(_InternalRuntimeDownloadArgs)
.azure/pipelines/ci-public.yml:588
- This also uses
RunTemplateTests, which doesn’t match theOnlyTestProjectTemplatesproperty in your MSBuild scripts. Use the same property name to ensure the skip logic actually takes effect.
/p:VsTestUseMSBuildOutput=false /p:RunTemplateTests=false

Should significantly cut down on the time it takes to run Helix jobs (@BrennanConroy reports almost an hour of time save). Also adds a new job that will only run when the ProjectTemplates folder is touched, which runs just the template tests in Helix.
Note - some template tests run only in the local jobs. Those will still run in all PRs (but those ones are very quick)
