FAQ - Automation - QTP (121 to 130)

121. Discuss QTP Environment.

QuickTest Pro environment using the graphical interface and ActiveScreen technologies - A testing process for creating test scripts, relating manual test requirements to automated verification features - Data driving to use several sets of data using one test script.

122. Explain the concept of how QTP identifies object.

During recording QTP looks at the object and stores it as test object. For each test object QT learns a set of default properties called mandatory properties, and look at the rest of the objects to check whether this properties are enough to uniquely identify the object. During test run, QTP searches for the run time objects that match with the test object it learned while recording.

123. Object Repositories types, which & when to use?

Deciding Which Object Repository Mode to Choose
To choose the default object repository mode and the appropriate object repository mode for each test, you need to understand the differences between the two modes.
In general, the object repository per-action mode is easiest to use when you are creating simple record and run tests, especially under the following conditions: You have only one, or very few, tests that correspond to a given application, interface, or set of objects.
You do not expect to frequently modify test object properties.
You generally create single-action tests.
Conversely, the shared object repository mode is generally the preferred mode when: You have several tests that test elements of the same application, interface, or set of objects.
You expect the object properties in your application to change from time to time and/or you regularly need to update or modify test object properties.
You often work with multi-action tests and regularly use the Insert Copy of Action and Insert Call to Action options.

124. Can we Script any test case with out having Object repository? Or Using Object Repository is a must?

No. You can script without Object repository by knowing the Window Handlers, spying and recognizing the objects logical names and properties available.

125. How to execute a WinRunner Script in QTP?

(a) TSLTest.RunTest TestPath, TestSet [, Parameters ] –> Used in QTP 6.0 used for backward compatibility Parameters : The test set within Quality
, in which test runs are stored. Note that this argument is relevant only when working with a test in a Quality
project. When the test is not saved in Quality
, this parameter is ignored.
e.g : TSLTest.RunTest “D:\test1″, “”

(b) TSLTest.RunTestEx TestPath, RunMinimized, CloseApp [, Parameters ] TSLTest.RunTestEx “C:\WinRunner\Tests\basic_flight”, TRUE, FALSE, “MyValue” CloseApp : Indicates whether to close the WinRunner application when the WinRunner test run ends. Parameters : Up to 15 WinRunner function argument

126. How to clear the AutoComplete?

1 In your Internet Explorer’s menu bar, choose Tools > Internet Options > Content tab.
2 Click AutoComplete in the Personal information area. The AutoComplete Settings dialog box opens.
3 In the Use AutoComplete for area, clear the User names and passwords on forms option.
4 Click OK to save your changes and close the AutoComplete Settings dialog box, then click OK again to close the Internet Options dialog box.

127. What is Object Spy in QTP?

Using the Object Spy, you can view the properties of any object in an open application. You use the Object Spy pointer to point to an object. The Object Spy displays the selected object’s hierarchy tree and its properties and values in the Properties tab of the Object Spy dialog box.

128. What is the Diff between Image check-point and Bit map Check point?

Image checkpoints enable you to check the properties of a Web image. You can check an area of a Web page or application as a bitmap. While creating a test or component, you specify the area you want to check by selecting an object. You can check an entire object or any area within an object. QuickTest captures the specified object as a bitmap, and inserts a checkpoint in the test or component. You can also choose to save only the selected area of the object with your test or component in order to save disk Space For example, suppose you have a Web site that can display a map of a city the user specifies. The map has control keys for zooming. You can record the new map that is displayed after one click on the control key that zooms in the map. Using the bitmap checkpoint, you can check that the map zooms in correctly.
You can create bitmap checkpoints for all supported testing environments (as long as the appropriate add-ins are loaded).
Note: The results of bitmap checkpoints may be affected by factors such as operating system, screen resolution, and color settings.

129. How many ways we can parameterize data in QTP ?

There are four types of parameters:
Test, action or component parameters enable you to use values passed from your test or component, or values from other actions in your test.
Data Table parameters enable you to create a data-driven test (or action) that runs several times using the data you supply. In each repetition, or iteration, QuickTest uses a different value from the Data Table.
Environment variable parameters enable you to use variable values from other sources during the run session. These may be values you supply, or values that QuickTest generates for you based on conditions and options you choose.
Random number parameters enable you to insert random numbers as values in your test or component. For example, to check how your application handles small and large ticket orders, you can have QuickTest generate a random number and insert it in a number of tickets edit field.

130. What are the Debugging modes used in QTP?

Different Debugging modes used in QTP are
* Step Into : To run only the current line of the active test or component.
* Step Out : Runs to the end of the called action or user-defined function, then returns to the calling action and pauses the run session.
* Step Over : to run only the current step in the active test or component. When the current step calls another action or a user-defined function, the called action or function is executed entirety, but the called action script is not displayed in the QuickTest window.
