Summary

  • Adds PHPUnit integration/unit tests for 6 Core classes with no prior test coverage
  • Covers constructor/static init, main public methods, and error paths for each class
  • Follows existing WP_UnitTestCase patterns used throughout the test suite

Files changed

Test file Class under test Tests
ChangeLoggerTest.php ChangeLogger 20+
ContextProvidersTest.php ContextProviders 15+
ExportTest.php Export 15+
FreshInstallDetectorTest.php FreshInstallDetector 12+
OnboardingInterviewTest.php OnboardingInterview 15+
OnboardingManagerTest.php OnboardingManager 15+

Acceptance criteria

  • Test file created for each class in tests/GratisAiAgent/Core/
  • Each test covers constructor, main public methods, and error paths
  • PHPCS passes on all new files (zero violations)
  • No modifications to existing production code

Runtime Testing

Risk level: Low — test files only; no production code changes.
Testing method: self-assessed — PHPCS clean; test structure mirrors existing passing test files.

Closes #699

Poem

🐰 Six classes now have their stories told,
With tests that catch both new and old,
Assertions march in perfect rows,
Where every edge case flow now glows! ✨

🚥 Pre-merge checks | ✅ 5
✅ Passed checks (5 passed)
Check name Status Explanation
Description Check ✅ Passed Check skipped - CodeRabbit’s high-level summary is enabled.
Title check ✅ Passed The PR title clearly and specifically summarizes the main change: adding unit tests for six untested Core classes, directly matching the changeset content.
Linked Issues check ✅ Passed All acceptance criteria from issue #699 are met: test files created for all 6 classes, each covering constructor/static init/public methods/error paths, and per PR summary all tests pass without regressions.
Out of Scope Changes check ✅ Passed All changes are in-scope test additions; no production code modifications; PR explicitly states test-only changes with no impact on existing functionality.
Docstring Coverage ✅ Passed Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%.

Inline comments:
In `@tests/GratisAiAgent/Core/ChangeLoggerTest.php`:
- Around line 26-36: The tests only call ChangeLogger::end() but never clear the
custom table, so state leaks between tests; update the ChangeLoggerTest set_up()
and tear_down() methods to also truncate/delete all rows from the
gratis_ai_agent_changes_log table (after calling ChangeLogger::end() or before
starting each test) so each test starts with a clean table; reference the
ChangeLoggerTest::set_up, ChangeLoggerTest::tear_down methods and keep the
ChangeLogger::end() calls while adding a DB truncate/delete of
gratis_ai_agent_changes_log to both setup and teardown.

In `@tests/GratisAiAgent/Core/FreshInstallDetectorTest.php`:
- Around line 179-199: The test only asserts
FreshInstallDetector::isFreshInstall() returns a bool but doesn't verify that
default-titled posts/pages are ignored; update the test to call
FreshInstallDetector::getStatus() (or otherwise access the returned status
object) and assert that the has_real_posts and has_real_pages flags are false
after creating the 'Hello world!' post and 'Sample Page' page so the behavior is
explicitly checked; keep the existing factory creation of posts/pages and
replace or augment the final assertion with assertions on
getStatus()->has_real_posts and getStatus()->has_real_pages.

In `@tests/GratisAiAgent/Core/OnboardingInterviewTest.php`:
- Around line 325-363: Update the tests that currently only check the return
value to assert database state: after calling OnboardingInterview::save_answers
in test_save_answers_skips_blank_answers, query the
{$wpdb->prefix}gratis_ai_agent_memories table (using global $wpdb) to assert
that a memory exists for 'primary_goal' with the exact content 'Real answer' and
that no row exists for 'target_audience' (or that stored answer is not
whitespace-only); in test_save_answers_stores_memories assert that at least two
rows were inserted and/or assert presence of specific memories for
'primary_goal' and 'target_audience' with their expected text; in
test_save_answers_uses_fallback_label_for_unknown_id assert that a memory row
was inserted for the unknown_question_id answer and that its label uses the
fallback text (not the key), confirming the fallback label was stored in the
gratis_ai_agent_memories table; use OnboardingInterview::save_answers, $wpdb and
the table name to locate rows and assert their content/counts.
- Around line 26-37: The fixture must also clear the stored memories to prevent
test leakage: in both set_up() and tear_down(), after calling
OnboardingInterview::reset() (and alongside delete_option(
SiteScanner::STATUS_OPTION ) in tear_down()), call
delete_option('gratis_ai_agent_memories') so any memory rows/options written by
save_answers() are removed between tests.

In `@tests/GratisAiAgent/Core/OnboardingManagerTest.php`:
- Around line 189-203: The test currently only asserts
OnboardingManager::TRIGGERED_OPTION was set but doesn't verify the "fresh site"
branch scheduled a scan; after calling OnboardingManager::maybe_trigger() add an
assertion that SiteScanner::CRON_HOOK was scheduled (e.g., check
wp_next_scheduled for SiteScanner::CRON_HOOK is truthy) to prove the cron job
side effect; keep the existing cleanup of SiteScanner::STATUS_OPTION and ensure
the fixture leaves memories empty so the scheduled-cron assertion validates the
fresh-path behavior.
- Around line 27-39: The tests leave rows in the memories table causing
order-dependent failures; update the test setup/teardown to clear the memories
table so each test starts clean: inside set_up() and/or tear_down() (alongside
OnboardingManager::reset() and OnboardingInterview::reset()) execute the code to
truncate or delete all rows from the memories table (e.g., via the memories
model or DB connection used in tests) so
test_maybe_trigger_marks_triggered_when_memories_exist() does not affect other
maybe_trigger() tests.

Memory content is stored as 'Label: answer', not raw answer text.
Use LIKE queries and assertStringContainsString to match the actual
storage format. Also verify fallback label for unknown question IDs.

Closing Summary

What was done

  • Fixed test isolation issues in 4 Core test files per CodeRabbit review findings
  • ChangeLoggerTest: Added DELETE FROM gratis_ai_agent_changes_log in both set_up() and tear_down() to prevent row leaks between tests
  • OnboardingInterviewTest: Added DELETE FROM gratis_ai_agent_memories in both set_up() and tear_down(); strengthened save_answers() tests with DB state assertions verifying stored memories, blank answer filtering, and fallback label usage
  • OnboardingManagerTest: Added DELETE FROM gratis_ai_agent_memories in both set_up() and tear_down() to prevent order-dependent failures; added assertNotFalse(wp_next_scheduled(SiteScanner::CRON_HOOK)) to verify the fresh-site path schedules a scan
  • FreshInstallDetectorTest: Replaced weak assertIsBool() with specific assertFalse($status['has_real_posts']) and assertFalse($status['has_real_pages']) via getStatus()

Testing Evidence

  • Level: self-assessed (test files only, no production code changes)
  • All PHPUnit checks pass (WP 6.9, WP trunk, Coverage) — reduced failures from 14 to 0
  • PHPCS: zero violations
  • PHPStan: pass (pre-existing WP_UnitTestCase baseline only)
  • All Playwright E2E, ESLint, Stylelint, Build Check, Bundle Size Budget pass

Key decisions

  • Used LIKE queries for memory content assertions since save_answers() stores content as "Label: answer" format, not raw answer text
  • SiteScannerTest idempotency fix was not applicable — no SiteScannerTest file exists in this PR
