What is a .webmanifest file?

A web app manifest (.webmanifest) is a JSON file that describes a Progressive Web App to the browser, declaring its name, icons, theme colors, start URL, and display mode. It enables installation to a device home screen and standalone launching. It is linked from HTML via a manifest link element.

How to use this file

Use an example webmanifest to test PWA installability, manifest JSON parsing, icon and display-mode handling, and browser or auditing tools like Lighthouse.

How to use this file for testing

“Web App Manifest (webmanifest)” is a deterministic Testaroo fixture for Config testing, Conversion testing. TOML, INI, YAML, .env, and dotfile configuration samples with nested sections and typed values, for testing config parsers, loaders, and environment tooling.

Documented properties for this file: W3C Web App Manifest. 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.

Data fixtures document their exact quirks (delimiters, encodings, null handling, schema, and row counts) in the spec table. Point your parser or importer at the file and assert it handles the documented edge cases; clean and deliberately-messy siblings make before/after diffs straightforward.

Point your config loader at the file and assert it reads the documented sections and typed values, including any deliberately-tricky nesting or comments.
