robots.txt - field case, tabs and indentation
A robots.txt using upper-case, mixed-case and indented field names, a tab-indented rule, a value with no space after the colon, and both trailing and full-line comments. For testing that field names are treated case-insensitively while path values stay case-sensitive.

Testing contract
Expected to pass- Scenario
- Parse the file, then test /Private/x, /private/x and /tmp/keep/x for ExampleBot.
- Expected result
- All five rules are recognised despite the casing and indentation; /Private/x is disallowed but /private/x is allowed because paths are case-sensitive; /tmp/keep/x is allowed by the space-less `Allow:/tmp/keep/`.
What is a .txt file?
TXT is a plain-text file containing unformatted character data with no styling or structure beyond line breaks. Its interpretation depends on character encoding, most commonly UTF-8, and on line-ending convention. It is the most universal and portable text container.
How to use this file
Use an example TXT to test encoding detection, line-ending (LF versus CRLF) handling, and any tool that reads or streams raw text input.
How to use this file for testing
“robots.txt - field case, tabs and indentation” is a deterministic Novus Examples fixture for Web assets, Web scraping, Editor testing. 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 · robots.txt (RFC 9309). 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.

- xmlSitemap index over three sitemapsA sitemap index listing three child sitemaps, one dated with a plain date, one with a full W3C datetime, and one with no lastmod at all. Two of the children ship alongside it, so a crawler can be walked from index to URL.
- xmlSitemap shard 1 (core pages)The first child of the sitemap index: six core URLs with a deliberately uneven mix of lastmod, changefreq and priority, including one entry that carries nothing but a loc. For testing that optional sitemap fields really are optional.
- xmlSitemap shard 2 (blog and legal)The second child of the sitemap index: six URLs dated with W3C datetimes in two different timezone offsets, including a changefreq of never and a priority of 0.1. For testing datetime normalisation and priority ordering.
- xmlSitemap with a deliberately invalid hreflang clusterA deliberately invalid hreflang cluster: an `en-UK` region that does not exist, an underscore locale, a German page that never links back, a Spanish self-reference dropped to http, and no x-default anywhere. For testing that an international audit reports each defect rather than the first one.
- xmlSitemap with a reciprocal hreflang clusterA sitemap whose three URLs form a complete hreflang cluster: every page lists every locale including itself and a shared x-default. This is the shape an international audit should pass, and the reference twin of the broken cluster.
