What is Object Repository

Object Repository is a place where all recorded or added objects are stored.
When you record the application, recorded objects are stored in the Object Repository, in order to use them later.
Object Repository mainly identifies how it will recognize an object at the time of replay.
Object Repository displays a tree of all objects in the current component or in the current action or entire test (depending on the object repository mode you selected)
We can view or modify the test object description of any test in the repository or we can add new objects to the repository.
There are two types of Object Repositories : Per Action and Shared Action

When we are working in Object Repository, Per Action mode, Quick test creates a new object repository for each action.
When we are working in Object Repository, Shared Action mode, Quick test adds new objects to the object repository.
If we record operations on a object that already exists in the Shared Object Repository, Quick test uses the existing information, and does not add the object to the Object Repository.
