Find files, editable templates and browser test targets by what you need to make or test. The directory below is cut by format; the two collections under it cut the same library by subject and by workflow.
The same 12-person social network in GEXF 1.3 (Gephi's native format): node attributes and weighted edges. The format twin of the GraphML file, for testing Gephi imports and GraphML↔GEXF conversion.
A small synthetic social network in GraphML: 12 people in two communities with a few bridging ties, carrying node attributes (name, age, community) and weighted edges. Twinned with a GEXF file for testing graph importers and format converters.
Where the original view of person lifting weights in a gym, indoor lighting landed inside the expanded frame, as JSON: the rectangle 192,0 to 704,512 in a 704x512 canvas, the padding that produced it, and the 40-pixel feather that means the comparison must be inset. Authored BEFORE the expansion ran, so it is ground truth rather than a rectangle recovered afterwards by matching the original against the result - which is what a consumer would otherwise have to do, and which cannot distinguish a correct offset from a plausible one.
A football-style league table: position, played, won/drawn/lost, goals for/against, goal difference, and points for ten teams, derived from a full round of synthetic match results. Paired with the results JSON.
The full round of match results behind the league table: home/away teams, scores, and dates as a JSON array. A fixture for testing sports-data importers and standings calculators.
An OpenSSH-format Ed25519 public key (the shareable half of the key pair): a single line of algorithm, Base64 key blob, and comment, for testing SSH public-key parsers and authorized_keys tooling.
Machine-readable description of all 16 variants in this group: the file, the kind of damage, the measured parameters that produced it and what each one is expected to demonstrate. Provided so a test suite can walk the ladder programmatically instead of hard-coding filenames.
The customer dimension of a star schema: surrogate key, name, city, country, and segment. Joins to the sales fact table on customer_key. Names are synthetic.
The date dimension of a star schema: one row per day with a YYYYMMDD surrogate key and calendar attributes (year, quarter, month, weekday). Joins to the sales fact table on date_key.
The sales fact table at the centre of a star schema: 300 sale lines with foreign keys to the date, product, and customer dimensions plus quantity and amount measures. A fixture for testing joins, star-schema imports, and BI tools.
A year of daily OHLCV stock candles (open/high/low/close/volume) as a seeded random walk: a realistic finance time-series for testing charting, indicators, and importers. JSON twin included.
A structured application log in logfmt, space-separated key=value pairs (ts, level, msg, method, path, status, duration, request_id) as used by many Go and Heroku-style services. A fixture for testing logfmt parsers.
Machine-readable description of all 16 variants in this group: the file, the kind of damage, the measured parameters that produced it and what each one is expected to demonstrate. Provided so a test suite can walk the ladder programmatically instead of hard-coding filenames.
A customer-survey response set: 60 respondents rating five statements on a 1–5 Likert scale plus a 0–10 NPS score and a segment. A fixture for testing survey analysis, aggregation, and NPS/CSAT calculations.
