Move structured data testing into HTML validate plugin framework by Copilot · Pull Request #155 · fulldecent/github-pages-template

Copilot · 2025-08-20T03:23:57Z

This PR migrates structured data testing from standalone CLI scripts into the HTML validate plugin framework, providing better integration and consistency with other validation rules.

Changes Made

New HTML Validate Plugin

Created test/plugin.html-validate.structured-data.mjs that validates JSON-LD structured data
Plugin detects <script type="application/ld+json"> tags and extracts their content
Uses the existing structured-data-testing-tool to validate each JSON-LD script individually
Reports parse errors and validation failures through the HTML validate framework

Framework Integration

Added the new rule to the main plugin configuration and HTML validate config
Updated fixture test expectations to include structured data validation results
Plugin follows the same conventions as other HTML validate plugins in the repository

Cleanup

Removed standalone test-structured-data script from package.json
Removed standalone structured data tests from the main test script
Updated README.md to reflect that structured data testing is now integrated

Build Fixes

Fixed formatting issues in test/fixtures/required-results.json
Added missing https-links rule validation for ensure-https.html test fixture
All linting and tests now pass

Latest Updates

Pulled in recent changes from main branch
Resolved merge conflicts in package.json by keeping integrated approach
Removed obsolete standalone structured data test files that came from main
Verified all tests and linting pass with latest changes

Enhanced Error Messages

Improved JSON-LD parse error messages to include specific syntax error details
Enhanced validation failure messages to show failed test counts and details
Better error handling for general testing errors with detailed context
Updated fixture test expectations to match improved error messages

Upstream Integration

Merged latest upstream changes including new test-test workflow structure
Adapted to separated test validation (test-test) and build testing (test) approach
Resolved merge conflicts while maintaining integrated structured data testing
Verified compatibility with new GitHub Actions workflow structure

Test Fixture Formatting Fix

Updated required-results.json to match current output format from test framework
Fixed formatting inconsistency between test output and expected results
Applied prettier formatting to ensure consistency with project style
Verified all tests pass with corrected formatting

Benefits

Consistency: Structured data validation now follows the same patterns as other HTML validation rules
Better Error Reporting: Errors are reported with precise line/column information and integrated into the HTML validate output
Detailed Error Messages: Specific error information extracted from structured-data-testing-tool output
Simplified Testing: No need for separate test commands - everything runs through yarn test
Fixture-Based Testing: Uses the same fixture testing approach as other plugins
Workflow Integration: Compatible with new separated test validation structure

Validation

The plugin correctly:

✅ Validates valid JSON-LD without errors
✅ Detects JSON-LD parse errors with specific syntax error details
✅ Detects structured data validation failures with test counts
✅ Provides detailed error context from the testing tool
✅ Integrates with existing test suite
✅ Passes all linting rules
✅ Works with latest changes from main branch
✅ Compatible with new test-test workflow structure
✅ Test fixtures now properly formatted and validated

Fixes #154.

@copilot please use better error messages based on what the structured testing tools are able to provide

can you do a better error message than this?

Improved to extract specific parse error details: now shows "JSON-LD parse error: SyntaxError: Expected property name or '}' in JSON at position 11" instead of generic message. (6b5765a)

@copilot carefully see what has happened upstream and resolve the merge conflicts

Merge conflicts resolved successfully. Integrated upstream changes including the new test-test workflow structure while maintaining the structured data plugin integration. Adapted scripts to separate test validation (test-test) from build testing (test) as per the new workflow. All tests and linting pass. (4a1d502)

+    const tempDir = "/tmp";
+    const tempFileName = `structured-data-${Date.now()}-${Math.random().toString(36).substr(2, 9)}.html`;


Use substring() instead of the deprecated substr() method. Replace .substr(2, 9) with .substring(2, 11).

Suggested change

const tempFileName = `structured-data-${Date.now()}-${Math.random().toString(36).substr(2, 9)}.html`;

const tempFileName = `structured-data-${Date.now()}-${Math.random().toString(36).substring(2, 11)}.html`;

+  testStructuredData(content, scriptElement) {
+    // Create a temporary HTML file with just this JSON-LD script
+    const tempDir = "/tmp";


Hardcoded /tmp directory may not exist on all systems (e.g., Windows). Use os.tmpdir() from the Node.js os module for cross-platform compatibility.

+
+      // Run structured-data-testing-tool on the temporary file
+      const result = execSync(`yarn dlx structured-data-testing-tool --file "${tempFilePath}"`, {


The tempFilePath variable is not properly escaped for shell execution, which could lead to command injection if the path contains special characters. Use proper argument escaping or pass arguments as an array to avoid shell injection vulnerabilities.

@copilot See the GitHub action test results. And you should be able to reproduce this by running the yarn script to yourself.

You need to update the expected test results if they are incorrect

GitHub Actions test failures were due to formatting inconsistency in test fixtures. Updated required-results.json to match current test framework output format and applied prettier formatting. All tests now pass locally: test-test ✅, test ✅, lint ✅. The issue was that the test framework generates 4-space indented JSON but the expected results file was using 2-space indentation.
