Unicode test data for internationalization testing: combining marks, bidi overrides, ZWJ emoji, homoglyphs. Deterministic seeds, and every value explains what it breaks.

QA test fixtures and CI seed data with reproducible seeds, so pinned test runs return identical rows every time. 16 field types, each value explaining what it breaks.

Canonical injection test strings for checking your own escaping: SQL tautology, XSS, path traversal, template injection. Harmless probes, not working exploits. Reproducible seeds.

Fuzz testing input data for validation layers: malformed strings, boundary values, control characters. 16 field types, reproducible seeds; each value explains what it breaks.

Boundary value test data for off-by-one bugs: int32 and int64 limits, max-length strings, empty values. Deterministic seeds, and every value explains what it breaks.

Integer and floating-point edge cases: int32/int64 limits, NaN, infinity, denormals, and IEEE 754 rounding. Deterministic seeds, and every value explains what it breaks.

Malformed and hostile string test data for input handling: control characters, null bytes, encoding edge cases. Reproducible seeds, and every value explains what it breaks.

Date and time edge cases: Feb 29, DST gaps, year 2038, leap seconds, and quarter-hour UTC offsets. Reproducible seeds, and every value explains what it breaks.
