# WaitForDomainReload `WaitForDomainReload` is an [IEditModeTestYieldInstruction](./reference-custom-yield-instructions.md) that you can yield in Edit Mode tests. It delays the execution of scripts until after an incoming domain reload. If the domain reload results in a script compilation failure, then it throws an exception. ## Constructors | Syntax | Description | | ---------------------------- | ------------------------------------------------------------ | | `WaitForDomainReload()` | Create a new instance of the `WaitForDomainReload` yield instruction. | ## Example ``` C@ [UnitySetUp] public IEnumerator SetUp() { File.Copy("Resources/MyDll.dll", @"Assets/MyDll.dll", true); // Trigger a domain reload. AssetDatabase.Refresh(); yield return new WaitForDomainReload(); } ```
