cfi_converter_test.go:
- TestFindTextInNode_SingleTextNode: baseline single-node match
- TestFindTextInNode_CrossEmElement: 'Vokalia and Consonantia' across
two <em> elements — verifies match returns the 'Vokalia' text node
- TestFindTextInNode_CrossStrongElement: text crossing <strong> boundary
- TestFindTextInNode_DoesNotCrossParagraphs: verifies block boundary
enforcement — text split across <p> elements is NOT matched
- TestFindTextInNode_NestedFormatting: <em><strong> nesting
- TestFindBlockParent: verifies findBlockParent walks up through inline
elements to find block-level <p>
- TestCollectInlineText: verifies text segments are collected in order
with correct content
kepub_cfi_converter_test.go:
- TestKEPUBConvertWithEmElements: previously skipped, now expects exact
precision and verifies round-trip conversion works for text spanning
<em> element boundaries
Test coverage for KEPUBCFIConverter with programmatically generated
EPUB and KEPUB zip fixtures:
- KEPUB->Standard text search conversion (exact precision)
- Standard->KEPUB text search conversion with round-trip verification
- Multi-position round-trip (3 phrases across different paragraphs)
- Cross-chapter conversion (spine index 1)
- No-context-text conversion (extracts surrounding text from resolved node)
- Invalid CFI handling (falls back to percentage)
- Percentage fallback for unresolvable CFIs
- 5-paragraph round-trip covering different document positions
- CFI structural difference verification (koboSpan adds DOM steps)
- Spine index consistency between EPUB and KEPUB
- Real book conversion test (skips if file not present)
- extractSurroundingText unit tests
