Split WSLA/WSLC tests into a separate CI runner by benhillis · Pull Request #14472 · microsoft/WSL

benhillis · 2026-03-19T00:04:47Z

Add a WSLA_TEST_CLASS macro that tags test classes with TestCategory=WSLA, allowing TAEF /select filters to split them into a dedicated CI job.

Add WSLA_TEST_CLASS macro that adds TestCategory=WSLA metadata
Tag all 12 WSLA/WSLC test classes (WSLATests, WslcSdkTests, WSLC E2E, WSLC CLI)
Add 'wsla' version to CI pipeline test matrix

This runs WSLA/WSLC container tests (153 tests) in parallel with traditional WSL tests (389 tests), reducing the critical path of the CI pipeline.

Pull request overview

This PR splits WSLA/WSLC (container-related) Windows tests into a dedicated CI lane by tagging those test classes with a TestCategory=WSLA TAEF property and updating CloudTest/pipeline configuration to filter on that category.

Changes:

Introduce WSLA_TEST_CLASS (and refactor shared class properties) to apply TestCategory=WSLA metadata to selected TAEF test classes.
Update CloudTest jobs to (a) exclude WSLA-tagged tests from the standard WSL test run and (b) add a new WSLA-only test job group.
Extend the pipeline test matrix with a wsla entry to run the new CloudTest map.

Pull request overview

Adds a WSLA-specific test category and CI split so WSLA/WSLC tests can run in a dedicated CloudTest/TAEF job, reducing overall CI critical-path duration.

Changes:

Introduces WSLA_TEST_CLASS (via common test macros) to tag WSLA/WSLC-related test classes with TestCategory=WSLA.
Splits CloudTest execution into two groups using TAEF /select filters (non-WSLA vs WSLA) and adds a new WSLA CloudTest group template.
Extends the pipeline test matrix with a wsla entry and generates per-image WSLA CloudTest specs.

Pull request overview

This PR enables splitting WSLA/WSLC container-related tests into a dedicated CloudTest job by tagging those test classes with TestCategory=WSLA and updating CloudTest/CI to run @TestCategory='WSLA' separately from the rest of the suite.

Changes:

Introduces WSLA_TEST_CLASS (adds TestCategory=WSLA) and applies it across WSLA/WSLC test classes.
Updates CloudTest TestGroup definitions to exclude WSLA tests from the default job and adds a new WSLA-only TestGroup.
Extends the pipeline test matrix to include a wsla version/job.
