Nullean.Entities.CsCheck.AutoBogus

An AutoBogus-backed generator for Nullean.Entities.CsCheck. Optional, and not the default.

GenAuto.Of<T>() in the main package builds any type itself: lock-free, shrinkable, plausible values mixed with edge cases (blank and hostile strings, NaN, negatives, undefined enums, Start == End). Use this package when you already configure AutoFaker (binders, per-type overrides, skip rules) and want to keep that investment, or when you want strictly plausible Bogus data.

using Nullean.Entities.CsCheck.AutoBogus;

Gen<Order> orders = GenAutoBogus.Of<Order>(faker => { /* your AutoFaker configuration: binders, overrides, skip rules */ });

OrderConstraints.All.ForAll(o => o.Total >= 0, gen: orders);                 // any API that takes a Gen<T> takes this
OrderConstraints.All.Preserves(OrderConstraints.Actions, start: orders);
OrderConstraints.Instance.Spec().Data(AutoMode.Plausible);                   // plausible start/argument data without this package

Every draw goes through CsCheck's PCG, so values are reproducible by seed and shrink by draw count and magnitude.

What to know

  • It generates plausible values only. No NaN, negatives, blank strings or undefined enums, so Probe reports most rules as "never violated" and RejectsInvalid as unfalsifiable. That is the main reason it is not the default.
  • Bogus's global lock. Randomizer.Locker is an internal static taken inside every draw and cannot be disabled, so a multi-threaded CsCheck run stops scaling at about two threads (measured: 71k Order draws/second on one thread, 97k on eight, against 617k and 1.6M for GenAuto.Of<Order>()).
  • IndexFaker/IndexVariable are reset to zero before every draw, so a rule reading f.IndexFaker is reproducible. f.IndexGlobal, f.UniqueIndex and Faker.GlobalUniqueIndex are process-wide statics shared with every other Faker: avoid them.
  • configure runs once per thread, not once per sample: keep it pure.

The measurements behind this split are in docs/autobogus-decision.md.
