Testing

The undo system supports many different kinds of undos such as undo group detach/attach, prefab extract all, etc, with different setup conditions. For this reason, the actions that are required to set up and execute a single test and its components are exposed via python scripts. This way it is possible to expose editor actions via a flexible and simple scripting language and test Sandbox python APIs at the same time.

Custom Test Example

Following is a commented test script example that attaches an object to a group, undoes this and checks if both actions have been performed successfully.
