Before we learn about Object Repository, let's quickly learn

How Object Identification Works in QTP?

  • QTP uses a  "human" like technology for object identification
  • During Record Time QTP tries to learn properties of a GUI object on which operation is performed.
  • During Run-Time, QTP compares the stored object properties with actual properties of the object available on screen and uniquely identifies an object independent of its location on the screen
  • The stored object and together with its properties is called TEST Object
  • During Run-Time, the actual object available on the application under test is called Run-Time Object
  • This is Quick Tests "Test Object Model"
  • Information about the Test Objects is stored in Object Repository
  • Add-ins help in  instructing Quick Test in  advance of the nature of object to be recorded so it as to reduce the time required to learn its properties

There are 2 Types of Object Repository in QTP

  1. Local Object Repository
  2. Shared Object Repository

Local Object Repository

  • Local Object Repository is the default object repository
  • It is specific to actions and can be used only for a particular action
  • Local Object Repository   is preferable when application is not dynamic with respect to time
  • Local Object Repository  cannot be reused
  • You can perform many operations in the local object repository such as -
  • Highlight an object stored in repository on the application under test
  • Check whether a particular object in your AUT is stored in the Object Repository
  • Cut , Copy , Paste  , Modify and Delete Objects
  • In case you have accidentally modified the value of a property you can update its description from the application using update function.

Shared Object Repository

  • Global or Shared Object  Repository is preferable when application is dynamic and object description change frequently
  • Between Shared and local object repository, shared object repository is more commonly used in automation projects
  • However, it has maintenance and administration overheads as compared to local object repository.

To create and use a shared object repository you need to perform three broad steps

  • Creating a Shared Object Repository
  • Associating a Shared Object Repository
  • Editing a Shared Object Repository

Let's look at them one at a time

Step 1) Creating a Shared Object Repository

  • All repositories are local by default.  To create a Shared Object Repository, in the Object Repository Dialog Box  , Click File > Export Local Objects
  • Repository files have an extension .tsr .Give a suitable name say "guru99" and save
  • The Shared Repository File is now created

Step 2)Associating a Shared Object Repository

  • Next step is to associate the repository to your test, which enables you to use it
  • To associate repository with a test, Click Resources > Associate Repository
  • You can select the Repository to associate with Actions available in your test.
  • Now you  can now use this shared repository to develop your test

Step 3) Editing a Shared Object Repository

  • You can use the Object Repository Manager to Edit a Share Repository.
  • Select Resources > Object Repository Manager .Open the Object Repository we created "guru99"
  • By Default, Repository is opened in Read-only mode. To enable editing click File > Enable Editing
  • Once editing is enabled you can all the operations like cut, copy, paste, rename objects etc that you can also do in Object Repository
  • Using  Object Repository Manager  is you can compare two Object Repositories. QTP will give you a static's of what's unique and common in both the repositories
  • You can use the Object repository merge tool to merge two repositories into one
