"""Tests for Sciendo using the_doi_slide function.

This test suite validates Sciendo's use of the_doi_slide generic function
following dance function guidelines Phase 4: Test Development.

Evidence analyzed:
- 6 HTML samples with perfect pattern consistency
- All show: citation_pdf_url = https://sciendo.com/pdf/{doi}
- DOI prefixes: 10.2478, 10.34763 (multi-publisher platform)
- Domain: sciendo.com (100% consistency)
- Access model: Open access with citation_pdf_url meta tags

Registry configuration:
- dance_function: 'the_doi_slide'
- format_template: 'https://sciendo.com/pdf/{doi}'
