Report Playwright Page Header Footer Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Make both exam sprint PDF reports render the report header on every page, format generated time as Beijing local time, and show current page / total pages in the footer.

Architecture: Keep the existing report HTML templates as the source of header content, but teach the Playwright PDF worker to extract that .report-header markup and pass it to Chromium's native displayHeaderFooter templates. Format Instant generatedAt in each renderer with Asia/Shanghai and yyyy-MM-dd HH:mm:ss.

Tech Stack: Java, Playwright Java, Chromium PDF, JUnit 5, AssertJ, PDFBox.

Task 1: Renderer Generated Time Format

Files:

  • Modify: abilities/exam-sprint/infrastructure/src/test/java/cn/yunzhixue/ability/center/examsprint/infrastructure/report/rendering/achievement/ClasspathAchievementExamSprintReportRendererTest.java
  • Modify: abilities/exam-sprint/infrastructure/src/test/java/cn/yunzhixue/ability/center/examsprint/infrastructure/report/rendering/outlook/ClasspathOutlookExamSprintReportRendererTest.java
  • Modify: abilities/exam-sprint/infrastructure/src/main/java/cn/yunzhixue/ability/center/examsprint/infrastructure/report/rendering/achievement/ClasspathAchievementExamSprintReportRenderer.java

  • Modify: abilities/exam-sprint/infrastructure/src/main/java/cn/yunzhixue/ability/center/examsprint/infrastructure/report/rendering/outlook/ClasspathOutlookExamSprintReportRenderer.java

  • [ ] Step 1: Write failing renderer tests

Add assertions that rendered HTML contains 2026-05-13 10:08:54 and does not contain 2026-05-13T02:08:54.657335Z for both report renderers.

  • Step 2: Run renderer tests to verify RED

Run: ./mvnw -pl abilities/exam-sprint/infrastructure -Dtest=ClasspathAchievementExamSprintReportRendererTest,ClasspathOutlookExamSprintReportRendererTest test

Expected: FAIL because current renderer uses Instant.toString().

  • Step 3: Implement Beijing time formatter

Use DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss").withZone(ZoneId.of("Asia/Shanghai")) in both renderers.

  • Step 4: Run renderer tests to verify GREEN

Run the same Maven command. Expected: PASS.

Task 2: Playwright Native Header and Footer

Files:

  • Modify: abilities/exam-sprint/infrastructure/src/test/java/cn/yunzhixue/ability/center/examsprint/infrastructure/report/pdf/PlaywrightExamSprintReportPdfGeneratorTest.java

  • Modify: abilities/exam-sprint/infrastructure/src/main/java/cn/yunzhixue/ability/center/examsprint/infrastructure/report/pdf/DefaultPlaywrightPdfWorker.java

  • [ ] Step 1: Write failing PDF test

Add a multi-page HTML test with .report-header, generate PDF, and assert extracted text contains repeated header text and footer page text such as 1/2 and 2/2 after whitespace normalization.

  • Step 2: Run PDF test to verify RED

Run: ./mvnw -pl abilities/exam-sprint/infrastructure -Dtest=PlaywrightExamSprintReportPdfGeneratorTest#generateRepeatsReportHeaderAndFooterPageNumbers test

Expected: FAIL because Playwright header/footer are not configured.

  • Step 3: Implement PDF options

In both page.pdf(...) call sites, call a shared method returning Page.PdfOptions with displayHeaderFooter=true, a header template built from the source .report-header, a footer template with <span class="pageNumber"></span> / <span class="totalPages"></span>, and top/bottom margins that reserve space.

  • Step 4: Run PDF test to verify GREEN

Run the same Maven single-test command. Expected: PASS.

Task 3: Full Relevant Verification

Files:

  • No production files beyond Task 1 and Task 2.

  • [ ] Step 1: Run all relevant infrastructure tests

Run: ./mvnw -pl abilities/exam-sprint/infrastructure test

Expected: PASS.

  • Step 2: Review diff

Run: git diff -- abilities/exam-sprint/infrastructure docs/superpowers/plans/2026-05-13-report-playwright-page-header-footer.md

Expected: only intended renderer, PDF worker, tests, and plan changes.
