From 0403b4f21f48f6769e74ba24b5d17bd7c11b114d Mon Sep 17 00:00:00 2001 From: Christopher Albert Date: Sat, 23 Aug 2025 13:29:12 +0200 Subject: [PATCH 1/4] test: add RED phase tests for GitHub Pages image path resolution - Issue #205 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive tests demonstrating current broken behavior where media files are copied AFTER FORD processes markdown files, causing broken image links in GitHub Pages documentation. Tests include: - Media file staging validation (fails until fix implemented) - Relative path resolution from generated HTML directories - Documentation build process integration testing - Image accessibility validation for GitHub Pages structure - Shell validation script for CI/CD pipeline Given-When-Then documentation provided for each test scenario. Tests demonstrate the issue and will pass once the media staging timing is fixed. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- scripts/validate_github_pages_images.sh | 107 ++++++++ ...est_github_pages_image_paths_issue_205.f90 | 234 ++++++++++++++++++ 2 files changed, 341 insertions(+) create mode 100755 scripts/validate_github_pages_images.sh create mode 100644 test/test_github_pages_image_paths_issue_205.f90 diff --git a/scripts/validate_github_pages_images.sh b/scripts/validate_github_pages_images.sh new file mode 100755 index 00000000..19f1addb --- /dev/null +++ b/scripts/validate_github_pages_images.sh @@ -0,0 +1,107 @@ +#!/bin/bash + +# Validation script for GitHub Pages image paths - Issue #205 +# +# This script validates that documentation images are correctly staged +# for GitHub Pages deployment with working relative path resolution + +set -e + +echo "============================================================" +echo "VALIDATING GITHUB PAGES IMAGE PATHS - Issue #205" +echo "============================================================" + +# Test results +TESTS_PASSED=0 +TESTS_FAILED=0 +CRITICAL_ISSUES=0 + +function test_result() { + local test_name="$1" + local result="$2" + local message="$3" + + if [ "$result" = "PASS" ]; then + echo "✓ PASS: $test_name" + [ -n "$message" ] && echo " $message" + TESTS_PASSED=$((TESTS_PASSED + 1)) + elif [ "$result" = "FAIL" ]; then + echo "✗ FAIL: $test_name" + [ -n "$message" ] && echo " $message" + TESTS_FAILED=$((TESTS_FAILED + 1)) + elif [ "$result" = "CRITICAL" ]; then + echo "❌ CRITICAL: $test_name" + [ -n "$message" ] && echo " $message" + CRITICAL_ISSUES=$((CRITICAL_ISSUES + 1)) + TESTS_FAILED=$((TESTS_FAILED + 1)) + else + echo "⚠ SKIP: $test_name" + [ -n "$message" ] && echo " $message" + fi +} + +# Test 1: Check if documentation build directory exists +if [ -d "build/doc" ]; then + test_result "Documentation build directory" "PASS" "build/doc exists" +else + test_result "Documentation build directory" "FAIL" "build/doc not found - run 'make doc' first" +fi + +# Test 2: Check if media staging directory exists +if [ -d "build/doc/media/examples" ]; then + test_result "Media staging directory" "PASS" "build/doc/media/examples exists" +else + test_result "Media staging directory" "CRITICAL" "build/doc/media/examples missing - images will be broken" +fi + +# Test 3: Check workflow and Makefile for proper media staging +if [ -f ".github/workflows/docs.yml" ]; then + if grep -A 5 -B 5 "make doc" .github/workflows/docs.yml | grep -q "cp -r doc/media/examples"; then + test_result "Workflow media staging" "CRITICAL" "Media copied after 'make doc' - will break image paths" + else + test_result "Workflow media staging" "PASS" "Media staging appears correct in workflow" + fi +else + test_result "Workflow file" "FAIL" "GitHub Actions workflow not found" +fi + +if [ -f "Makefile" ]; then + doc_section=$(sed -n '/^doc:/,/^[a-zA-Z]/p' Makefile) + if echo "$doc_section" | grep -n -E "(ford|cp.*doc/media)" | head -2 | tail -1 | grep -q "cp"; then + test_result "Makefile media staging" "CRITICAL" "Media copied after FORD - will break image paths" + else + test_result "Makefile media staging" "PASS" "Media staging appears correct in Makefile" + fi +else + test_result "Makefile" "FAIL" "Makefile not found" +fi + +# Summary +echo "" +echo "============================================================" +echo "VALIDATION SUMMARY" +echo "============================================================" +echo "Tests passed: $TESTS_PASSED" +echo "Tests failed: $TESTS_FAILED" +echo "Critical issues: $CRITICAL_ISSUES" + +if [ $CRITICAL_ISSUES -gt 0 ]; then + echo "" + echo "❌ CRITICAL ISSUES FOUND" + echo "GitHub Pages documentation will have broken images!" + echo "" + echo "REQUIRED FIXES:" + echo "1.
