public static class MockExtensions

Convenience helpers that let generated values become null/default with a tunable probability, plus small IList/IReadOnlyList helpers (PickRandom, Shuffle).

Methods

OrNull(T, float)

public static T OrNull<T>(this T value, float nullProbability = 0.3) where T : class

Return value or null with nullProbability.

Parameters

Name	Type
value	{T}
nullProbability	System.Single

Returns

{T}

OrNullable(T, float)

public static T? OrNullable<T>(this T value, float nullProbability = 0.3) where T : struct

Return value wrapped as a Nullable<T>, possibly as null. Use this for value types since OrNull is restricted to reference types — C# does not allow overload resolution based on class/struct constraints alone.

Parameters

Name	Type
value	{T}
nullProbability	System.Single

Returns

System.Nullable{{T}}

OrDefault(T, float)

public static T OrDefault<T>(this T value, float defaultProbability = 0.3)

Return value or default(T) with defaultProbability. Works for both reference and value types.

Parameters

Name	Type
value	{T}
defaultProbability	System.Single

Returns

{T}

PickRandom(IReadOnlyList)

public static T PickRandom<T>(this IReadOnlyList<T> items)

Pick a random element from items using MockMagic’s seeded RNG.

Parameters

Name	Type
items	System.Collections.Generic.IReadOnlyList{{T}}

Returns

{T}

Shuffle(IList)

public static void Shuffle<T>(this IList<T> items)

Shuffle items in place using MockMagic’s seeded RNG.

Parameters

Name	Type
items	System.Collections.Generic.IList{{T}}
