Novus Examples
Getting startedGetting started with Novus Examples: find and download a sample file
Novus Examples is a free library of 2,558 test files across 17 categories and 221 distinct extensions, generated by deterministic scripts rather than collected, so each one is copyright-clean and ships with an exact spec sheet. This guide covers what the catalog holds, how to find the right sample for the tool you are testing, and how to download it in your browser with no account.

Use casesTest a background remover with the right sample images
A background remover is only as good as the hardest image you test it on. This guide covers which sample images from Novus Examples genuinely stress a cutout (solid versus busy backgrounds, hair and edge detail, transparency and grayscale) and how to run them through the NSS Background Remover.

Formats & batchTest a file converter end to end with sample files
A converter can accept a file and still produce the wrong output. This guide covers grabbing sample files across formats from Novus Examples (image to image, documents to PDF, audio, video, and archives) running them through Novus Convert, and verifying the result actually holds up.

Use casesSample file types explained: what each sample is for
A reference for the sample variants in Novus Examples that are easy to misread: transparent versus opaque, grayscale versus color, CMYK versus sRGB, tiny versus oversized images, and the deliberate zero-byte, corrupt, and wrong-extension files built for error-handling tests.

Getting startedBrowse by purpose: find fixtures by what you are testing
The /for routes skip the format taxonomy entirely. Pick OCR, ASR, segmentation, CSV parsing, schema validation, or JWT and get the fixtures that exercise that specific thing.

Use casesTest with clean and noisy pairs
Paired fixtures (clean and noisy, colour and greyscale, source and scanned) differ in exactly one property, which is what makes a before/after test mean something.

Getting startedRead a spec sheet and use what it tells you
Every file in the library ships with its exact properties: noise sigma, silence timestamps, form fields, encodings, dimensions, and the seed that produced it. Here is how to use them.

Use casesTest against the twelve live targets
Twelve live pages, each exhibiting exactly one behaviour (landmarks, nested modals, infinite scroll, cookie banners, frame nesting) for accessibility, scraper, and browser-automation testing.

Use casesTest forms with HTML and AcroForm fixtures
The Forms category holds 94 fixtures (live HTML forms and AcroForm PDFs with known field inventories) for testing form fillers, validators, scrapers, and PDF editors.

Use casesTest a video pipeline with the 401-file video set
The video category grew from 70 files to 401, and the point of the expansion is that degraded clips now name the pristine clip they came from. This guide covers choosing codec, container, streaming, caption, and AI-video fixtures, and using the ground-truth pairing to turn "looks better" into a number.

Use casesBuild an OBS scene from a broadcast template
The 48 templates in the four broadcast categories each ship an OBS-compatible scene collection: a JSON file you import to get a scene already wired to the overlay you just downloaded. This guide covers downloading the pair, importing, and the one relink step OBS requires, and why it cannot be avoided.
