Data Driven Testing in QTP:

Data Driven Testing

                        Data driven testing is a concept introduced in the automation in order to implement re- testing.

Steps to be followed to perform data driven testing:

• Collect the test data in to the data table
• Generate the basic test
• Parameterize the test
• Execute the Test
• Analyze the result

Parameterization:

                        Parameterization is a process of replacing the constant values with parameters or variables in order to increase the scope of the test. Parameterize can be done in three ways

• Through data driver wizard
• Through key word view
• Manually

Navigation through Data Driver Wizard:

• Activate the menu item tools
• Select the option data driver
• Click on parameterize
• Click on next
• Click on the parameter option button
• Select the desired column name
• Click on ok
• Click on next
• Click on finish
• Finally click on ok

   Navigation Through Key word view:

• Go to key word view
• Select the desited constant value
• Click on configure the value button
• Select the option parameter
• Select the desired column name
• Click on ok

To avoid the above navigation one can directly type manually as follows:

A= datatable(“v1”,1)

Vbwindow(“form1”).vbedit(“val1”).set A

Vbwindow (“form1”).vbedit(“val2”).set datatable(“v2,1)

Vbwindow(“form1”).vbbutton(“Add”).Click

Vbwindow(“form1”).vbedit(“res”).check checkpoint(“RES”)

           

Navigation for parameterizing the check point:

• Right click on the check point statement
• Select the option check point properties
• Select the option parameter
• Click on the parameter options button
• Select the desired column name
• Click on ok
• Once again click on ok

We can also parameter the test objects from object repository/object repository manager.
