Issue #1444 — Test Strategy "Test Levels" chapter: verified complete (stale tracking issue)

Issue requirement

The tracking issue requested a dedicated chapter page for the Test Levels section of the Test Strategy:

• Page: gui/templates/strategy/testLevels.html
• Icon: fa-layer-group
• Wired into:
  • Aside nav: sub-item under Test Strategy (href_test_strategy_* labels in en_GB/en_US/ro_RO strings.txt)
  • General Overview: CHAPTERS entry in gui/templates/strategy/testStrategy.html with an Open chapter button
• i18n keys: ts.levels* in en.json + ro.json (header, sub, card titles, bullets)
• Content — Test levels: unit testing within the development environment; integration testing of component interactions; system testing of the whole product. Ownership: developers own unit and component integration; the QA team owns system and integration testing; stakeholders own acceptance (BAT/UAT).

Investigation result (measured)

Every requirement above is already implemented and verified working on the default branch. No defect is reproducible on this issue's subject matter; the issue was a tracking issue left open after the chapter landed.

Implementation provenance:

• f934433d7 — feat(strategy): dedicated pages + nav sub-items for all 18 Test Strategy chapters (Refs #1426, #1440-#1458) — created testLevels.html, the BFF chapter-map entry (api/strategy/index.php:62, num 5, fa-layer-group, ts.chapterLevels → testLevels.html) and the ASIDE sub-item (gui/templates/dashio/aside.tpl:145, label href_test_strategy_levels).
• 1ee2e0501 — jQuery loaded on all Test Strategy chapter pages so TLi18n initializes inside the mainframe iframe (Refs #1457).
• 945679c5b — the 179 chapter content keys (incl. ts.levels*) translated in all 8 non-en/ro bundles (Refs #1486, closed bug).

Verification evidence

• HTTP: testLevels.html → 200; testStrategy.html → 200.
• BFF (authenticated): GET api/strategy/index.php?action=chapters → status:ok with chapter 5 = {icon:"fa-layer-group", key:"ts.chapterLevels", descKey:"ts.chapterLevelsDesc", url:"/gui/templates/strategy/testLevels.html"}; footer keys present.
• ASIDE label href_test_strategy_levels present in locale/en_US/strings.txt:2286, locale/en_GB/strings.txt:2317, locale/ro_RO/strings.txt:34; common.php:2117 maps testStrategyLevels → testLevels.html.
• i18n: all 10 bundles (de en es fr it ja pt ro ru zh) contain all 10 ts.levels* keys + ts.chapterLevels/ts.chapterLevelsDesc with native translations; every bundle passes python3 -m json.tool.
• Browser (admin/admin): ASIDE → Test Strategy → Test Levels renders the chapter in the mainframe (header + sub, Test levels card with 3 bullets, Ownership card with 3 bullets incl. BAT/UAT, Back-to-Strategy link, locale switcher); General Overview card #5 shows fa-layer-group + Open chapter → navigates to testLevels.html; locale switch → Română renders Niveluri de Testare + translated bullets. Console: 0 messages.
• Event Viewer: events table has no new ERROR/WARNING entries.

Resolution

No code change was needed (nothing to fix). Closed after an 8/8 PASS regression suite (tmp/TLU_Test_Cases.md), browser/console/Event-Viewer clean.

Screenshots

• Test Levels — English render — testLevels.html: title/header/sub, both cards (Test levels + Ownership) with all six bullets, Back-to-Strategy link, locale switcher.
• Test Levels — Română render — same page after the locale switcher → Română: Niveluri de Testare, translated header/sub/cards/bullets proving client-side i18n.
