Testing contract

Expected to pass

Scenario: Exercise EPUB 3: E-book (nav document) in its epub versions workflow. The same book as EPUB 3, navigated by an XHTML navigation document (with an NCX fallback for older readers).
Expected result: ZIP package contains 11 members; mimetype='application/epub+zip'; mimetype compression method=0. Declared feature checks: navigation=nav.xhtml (+ NCX fallback); chapters=3; hasCover=True. The declared comparison counterpart is ebk-epub2; preserve the stated difference instead of expecting the container bytes to match.

What is a .epub file?

EPUB is the open e-book standard, a ZIP archive containing XHTML content documents, CSS, images, and a package manifest describing reading order and metadata. It supports reflowable text that adapts to screen size and is supported by most e-readers except Kindle natively. It is the dominant format for distributable e-books.

How to use this file

Use an example EPUB to test e-book parsing, ZIP-package and manifest handling, reading-order and metadata extraction, and rendering in e-reader applications.

How to use this file for testing

“EPUB 3: E-book (nav document)” is a deterministic Testaroo fixture for Conversion testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.

Documented properties for this file: EPUB 3.0. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.

E-book fixtures are structured archives documented down to their spine and manifest. Test readers and converters, and where a valid↔intentionally-invalid pair exists, assert graceful handling of the malformed container.
