Source map v3 with sourcesContent omitted

The same v3 map with the sourcesContent array removed, which is how most production builds ship: the mappings resolve but the original text has to be fetched from the paths in `sources`. For testing the fallback path of a debugger when originals are unavailable.

Testing contract

Expected to recover

Scenario: Symbolicate a frame using a map that carries no inlined original text.
Expected result: Positions still resolve to src/greet.js line 1 column 8, and the tool reports the source as missing or attempts to fetch src/greet.js instead of crashing on the absent sourcesContent array.

What is a .json file?

JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format representing objects, arrays, strings, numbers, booleans, and null. It is language-independent, human-readable, and the dominant format for web APIs and configuration. It requires a single well-formed root value.

How to use this file

Use an example JSON file to test parsers and serializers, schema validation, Unicode and number-precision handling, and API request or response processing.

How to use this file for testing

“Source map v3 with sourcesContent omitted” is a deterministic Testaroo fixture for Web assets, Code parsing, JSON parsing. Favicons, web app manifests, service workers, robots and sitemap files, Open Graph images, and .well-known resources, for testing web tooling, crawlers, PWA installers, and asset pipelines.

Documented properties for this file: seed 70400. 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.

Web-platform fixtures are standards-compliant samples against fictional example.com data. Test crawlers, PWA installers and manifest validators, favicon/icon pipelines, service-worker registration, or .well-known parsers against the documented structure.
