    Interface PropertyTestConfig

    Configuration for property-based tests that extends fast-check's Parameters.

    Split into four different variants to allow specific configuration for valid (non-throwing) and invalid (throwing) cases, both for normal and negated assertions.

    Generally, only valid and invalid are needed, since for most assertions, valid will be the same as invalidNegated, and invalid will be the same as validNegated.

    interface PropertyTestConfig {
        invalid: PropertyTestConfigVariant;
        invalidNegated?: PropertyTestConfigVariant;
        numRuns?: undefined;
        runSize?: "small" | "medium" | "large";
        valid: PropertyTestConfigVariant;
        validNegated?: PropertyTestConfigVariant;
    }
