Deterministic Generation

Use seeds to get identical data on every run.

Call WithSeed() to make generation reproducible. The same seed and country always produce the same data.

var customer = DataForger
    .ForCountry(Country.BR)
    .WithSeed(123)
    .Create<Customer>();

// Run it anywhere, any number of times:
// identical customer every time

Why it matters

• Snapshot tests stay stable across machines
• Failing CI runs reproduce exactly
• Seed data survives migrations and rebuilds
