Upload: Multipart Encoding Contract (HTML)
A form that mixes text, a checkbox group and two file controls under multipart form-data encoding. Paired with the raw multipart body shipped alongside it, so a parser can be checked against both the form and a request it would produce.

What is a .html file?
HTML (HyperText Markup Language) is the structural markup language of the web, using nested tags to define document content, semantics, and links. It is typically paired with CSS for presentation and JavaScript for behavior. It is the foundational format rendered by browsers.
How to use this file
Use an example HTML file to test parsers, DOM construction, sanitization of untrusted markup, and rendering or scraping pipelines.
How to use this file for testing
“Upload: Multipart Encoding Contract (HTML)” is a deterministic Novus Examples fixture for Form testing, Form parsing, Autofill testing, HTML parsing. HTML and PDF form files for testing scrapers, autofill, validators, and PDF form fillers across real-life use cases.
Documented properties for this file: 6 fields · multipart/form-data. 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.
This form is fictional SAMPLE content for tooling tests (autofill, scrapers, PDF fillers). It is not an official government, bank, or clinic form. Open the HTML offline or fill the PDF in any viewer; the demo submit path never stores data.
Embed this form
It's a single self-contained HTML file (inlined CSS, native validation, no external requests). Download it, host it on your own site, and drop it into any page with an iframe.

- emlEML — multipart/alternative Whose Parts DisagreeText and HTML alternatives that state different totals and different delivery dates. The spec says the parts must be alternative renderings of the same content, so this fixture shows what a tool extracts when they are not — the answer depends entirely on which part it picks.

- epubEPUB 3 - Scripted Content with the scripted PropertyAn EPUB 3 whose one content document declares properties="scripted" and contains a single inline script that rewrites one paragraph. It makes no network request and reads correctly with scripting switched off, so it tests the property and the fallback rather than the script.
- epubEPUB 3 - SVG Content Document in the SpineAn EPUB 3 whose first spine item is an SVG content document rather than XHTML, followed by a chapter that explains what should have appeared. For testing readers that assume every reading-order document is XHTML.
