Summary

Retain deterministic ten-file XML suites and retry only a killed suite one file at a time, so memory recovery cannot silently omit test files or suppress persistent failures.

Files Changed

.github/workflows/tests.yml, scripts/run-phpunit-batches.php

Runtime Testing

  • Risk level: Medium
  • Verification: self-assessed — php -l scripts/run-phpunit-batches.php; vendor/bin/phpcs scripts/run-phpunit-batches.php; vendor/bin/phpstan analyse scripts/run-phpunit-batches.php

Resolves #1839


aidevops.sh v3.32.317 plugin for OpenCode v1.18.30 with gpt-5.6-terra spent 3h 25m and 1,168,638 tokens on this as a headless worker.

Summary by CodeRabbit

  • Tests
    • Improved automated PHPUnit test execution with deterministic, memory-bounded batches.
    • Added safeguards to retry interrupted batches and verify that all discovered tests run.
    • Enhanced cleanup between test processes to reduce test isolation issues.
    • Improved failure reporting when tests are skipped or batch execution fails.
    • Coverage testing remains unchanged.

📝 Walkthrough

Walkthrough

The workflow replaces inline PHPUnit batching with a PHP runner. The runner validates inputs, discovers test files, executes bounded batches, cleans plugin tables, retries killed batches, and verifies execution through JUnit reports.

Changes

PHPUnit batching

Layer / File(s) Summary
Runner validation and test discovery
scripts/run-phpunit-batches.php
The runner validates PHPUnit, WordPress test configuration, database settings, and batch parameters. It discovers, deduplicates, sorts, and chunks Test.php files.
Batch execution and accounting
scripts/run-phpunit-batches.php, .github/workflows/tests.yml
Each batch uses a temporary PHPUnit configuration and JUnit report. The runner resets plugin tables, retries killed multi-file batches individually, verifies executed files, reports mismatches, and is invoked by non-coverage matrix jobs with batch size 10.

Estimated code review effort: 4 (Complex) | ~45 minutes

Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to 434e1

The batch runner now clears batch selection for per-file retries, allowing killed suites to retry correctly without skipping the selected files. No concrete current-head merge-blocking risk remains.
