    /// The `UnitySetUp` and <see cref="UnityTearDownAttribute"/> attributes are identical to the standard `SetUp` and `TearDown` attributes, with the exception that they allow for <see cref="IEditModeTestYieldInstruction"/>. The `UnitySetUp` and `UnityTearDown` attributes expect a return type of [IEnumerator](https://docs.microsoft.com/en-us/dotnet/api/system.collections.ienumerator?view=netframework-4.8).
