Summary

Replaces PHPUnit positional batching with deterministic XML suites, JUnit execution accounting, and memory-bounded ten-file CI batches.

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 2h 35m and 989,453 tokens on this as a headless worker.

Summary by CodeRabbit

  • Tests
    • Improved PHPUnit test execution by running tests in smaller, deterministic batches.
    • Added validation to confirm test discovery, configuration, and execution results.
    • Added database cleanup between batches to help prevent test data conflicts.

📝 Walkthrough

Walkthrough

The non-8.3 CI jobs now use a PHP script to discover, execute, clean, and verify PHPUnit test batches. The workflow sets a batch size of 10. The script validates configuration and reports failures when expected tests do not execute.

Changes

PHPUnit batching

Layer / File(s) Summary
Batch runner implementation
scripts/run-phpunit-batches.php
The new script discovers test files, validates PHPUnit and WordPress configuration, runs bounded batches, cleans plugin-owned tables, writes JUnit reports, and verifies executed files.
CI workflow integration
.github/workflows/tests.yml
Non-8.3 jobs invoke the script with PHPUNIT_BATCH_SIZE=10 instead of the inline find and xargs pipeline.

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

Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to 5ce4c

The runner should fix omitted CI tests and bound memory, but batch runs may diverge from shared PHPUnit settings or reject valid files that produce no JUnit testcase. These concerns should be addressed or accepted before relying on the new runner.

Explanation

The pull request addresses XML batching, JUnit accounting, failure propagation, and memory limits for [#1839]. However, the summary shows independent glob-based discovery instead of preserving PHPUnit's configured paths, suffixes, includes, and excludes. The required later-file failure fixture and normal-suite count comparison are also not evidenced.

Rename the temporary configuration variable.

$config_path already holds the WordPress test configuration path from line 40. Reusing the name for the temporary PHPUnit configuration hides the original value. Use $batch_config_path to keep the two paths distinct.

Base batch configurations on phpunit.xml.dist.

scripts/run-phpunit-batches.php builds an independent PHPUnit configuration. The current workflow runs batches with --no-coverage, so the omitted <coverage> section does not affect batch runs. If a shared setting is added to phpunit.xml.dist, it will not reach batch runs. Load phpunit.xml.dist with SimpleXML, replace only <testsuites>, and write it to the temporary file.
