How will you handle Java tree in QTP?

In this article we shall talk about how to handle java trees in quick test professional. But first let us see what a java tree actually is.

What is a Java Tree?

- Java tree is a data structure unique to java which can be used to display hierarchical data. 

- Java tree does not essentially holds or stores data rather it just provides the user with a view of the data i.e., in the way the data has been actually organized in the software system or application.

- The java tree obtains all this data by generating queries to the data model just like any other non- trivial swing component. 

- The data in a java tree is represented in a vertical manner. 

- Each row in this vertical representation displays only one data item called a node. 

- Each java tree has got it roots in the root node and this is from where all the branches of the tree descend. 

- In the default mode, the root node of a java tree is automatically displayed but this view can be modified. 

- The branch nodes are also referred to as children.

- The branch nodes can be expanded and collapsed as required. 

- Identification of a specific node in the tree can be done via a tree path. 

- A tree can be thought of as a container class that consists of elements of the type node. 

- These node elements can be thought of as thin cover over the actual data which has to be assigned some generic type. 

- These nodes cover the actual data which has to be represented by the means of a hierarchical data structure i.e., nothing but the java tree. 

- The java trees don’t become useful on their own. 

- They become useful when one can store and retrieve some tasks via them from the data base of the application.  

- Java trees are the one kind of the data structures which can represent the data in its true hierarchical manner. 

- It is possible for a node not to have any children whereas in other cases a node may have a large number of children and such nodes are referred to as branch nodes.

How to handle Java tree in QTP?

Java trees have a place in quick test professional also and now we going to discuss how to handle one. 

- For handling a java tree in quick test professional it is required that a java add–in is installed in the quick test professional. 

- In the tools menu there is one drop down list available by the name of “object identification”. 

- In this drop down list you will get one option “java” which facilitates the recognition of the objects. 

- Now from this drop down list select the tree option. 

- All you have to do is to add the properties that you want to be identified. 

- Just after doing this the quick test professional will be able to recognize the java tree. 

- If not this way you can even use DOM for the same purpose. 

- Here what you need to do is to make an appropriate code selection from the back ground and have it modified accordingly. 

- Another way can be to first select the option “JavaAdd” and then launch the quick test professional. 

- Your next step will be to record all the operations that are being performed up on the java tree. 

- If you face any problem with this way then you can try going back to the java tree object properties and modify the assistive and mandatory properties for easy identification. 

- You may face some difficulty while trying to expand all the nodes of the java tree even by using expandpath and expandrow commands.
