    Interface PropertyTestConfigVariantProperty<T>

    Variant configuration using a custom sync fast-check property.

    Use this when generator-based testing is insufficient and you need full control over the property logic, such as testing assertions with complex preconditions or custom shrinking behavior.

    interface PropertyTestConfigVariantProperty<T = any> {
        numRuns?: undefined;
        property: () => IProperty<T> | IPropertyWithHooks<T>;
        runSize?: "small" | "medium" | "large";
    }
