So far we have created a basic test. We should enhance the test by addinga synchronization point.

What is Synchronization?

5/25

What is Synchronization?

Synchronization is a step added to a test thatinstructs QuickTest to wait for the state of aproperty on a particular object to change beforeproceeding to the next step in the test.

Just like a manual tester will wait for a visual cueto know when the AUT has completed itsprocessing, we instruct QTP to wait for a cueprior to moving on to the next step in the test.

A synchronization point allows the test to pause

while an application process completes, beforemoving on to the next step.


6/25

Some Visual Cue Examples

A progress bar reaches 100% completion.

A status message appears.

A button becomes enabled.

A window opens and is ready for dataentry.

A pop-up message appears in response toan operation.

Examine the Application

Figure 5-3 Synchronize on the Progress Bar


8/25


QTP has a global object synchronization timeout. Whena step attempts to interact with an object that is notavailable when the application is still processing, QTPwill wait for either the object to become available or forthe object synchronization timeout to occur.

If one process takes considerably longer than others, theglobal synchronization timeout may not be long enoughfor the process to complete. And in this case, the nextstep might fail. To give these longer processes enoughtime to complete, we add a synchronization point toextend the time QTP will wait before moving on to thenext step.


9/25

Wait times often occur before an objectbecomes available for the next step.

For example, in the Flights application, once theInsert Order button has been clicked, a progressbar must complete before the reservation OrderNo. will be displayed. The progress bar mayrequire additional time before the test can

proceed. If insufficient time is allocated for thesespecial circumstances, the test may fail.



10/25

The error message, Object not enabledappears if QuickTest is running a testand proceeds to the next step before the

previous step has fully processed. QTP will wait only as long as it takes for

the process to complete, not necessarily

the full timeout.



11/25

Setting General Standard CheckpointOptions

Checkpoint timeout. Specifies the time interval (in seconds) during which

Quick Test attempts to perform the checkpoint successfully. Quick Test

continues to perform the checkpoint until it passes or until the timeout

occurs. If the checkpoint does not pass before the timeout occurs, the

checkpoint fails. For example, suppose it takes some time for an object toachieve an expected state. Increasing the checkpoint timeout value in thiscase can help ensure that the object has sufficient time to achieve thatstate, enabling the checkpoint to pass (if the data matches) before themaximum timeout is reached.

If you specify a checkpoint timeout other than 0, and the checkpoint fails,the Test Results window displays information on the checkpoint timeout.

Add a Synchronization step whileRecording

Figure 5-4 Insert a Synchronization Point


13/25

Synchronization points instruct QuickTest topause until an object property achieves aspecified value.

The easiest way to add a synchronizationpoint is while recording. Always add the synchronization point

immediately after the step to be synchronized.

From the QTP menu bar, choose INSERTSTEPSYNCHRONIZATION POINT. Step timeout values add to the global values.

When the synchronization timeout is setfor a step, this value is added to theglobal timeout value.

QTP has a default timeout between teststeps of 20000 milliseconds (20seconds).

May not wait for the full timeout to arrive.


16/25


For example: Lets say an object has a globaltimeout of 30 seconds and a synchronizedtimeout of 30 seconds. If the actual time it takesfor QTP to recognize the object is 40 seconds,

the test will move to the next step after 40seconds.

This feature applies to environments that do notsynchronize automatically.

Examples of auto-synchronizing environments:

- Web; SAP; TE

Understanding and Using RegularExpressions

Regular expressions enable Quick Test to identify objects and text stringswith varying values. You can use regular expressions when:

defining the property values of an object in dialog boxes or inprogrammatic descriptions

parameterizing a step creating checkpoints with varying values

For example, you can use a regular expression if you want to create a text

checkpoint on a date text string, but the displayed date changes according

to the current date. If you define the date as a regular expression, the

checkpoint checks that the captured text string matches the expected dateformat, rather than checking the exact date value.

A regular expression is a string that specifies a complex search phrase. By

using special characters, such as a period (.), asterisk (*), caret (^), and

brackets ([ ]), you can define the conditions of a search.


18/25

Using Regular Expressions for PropertyValues

If you expect the value of a property to change in a predictable way during

each run session, you can use regular expressions when defining or

parameterizing property values, for example, in the Object Repository

window, or in programmatic descriptions.

For example, your site may include a form in which the user inputs data and

clicks the Send button to submit the form. When a required field is not

completed, the form is displayed again for the user to complete. When

resubmitting the form, the user clicks the Resend button. You can definethe value of the buttons name property as a regular expression, so that

Quick Test ignores variations in the button name when clicking the button.


19/25

Using Regular Expressions inCheckpoints

When creating a standard checkpoint to verify the property values of an

object, you can set the expected value of an objects property as a regular

expression so that an object with a varying value can be verified.

For example, suppose you want to check that every window and dialog box

in your application contains the name of your application followed by a

hyphen (-) and a descriptive title. You can add a checkpoint to each dialog

box object in your test to check that the first part of the title contains the

name of your application followed by a hyphen.

When creating a text checkpoint to check that a varying text string is

displayed on your Web site or application, you can define the text string asa regular expression.


20/25

Using Regular Expressions inCheckpoints

For example, when booking a flight in the Mercury Tours sample Web site,

the total cost charged to a credit card number should not be less than $300.

You define the amount as a regular expression, so that Quick Test willignore variations in the text string as long as the value is not less than $300.

You can apply the same principles to any checkpoint type whose dialog box

contains a Configure Value area similar to that described in Configuring

Constant and Parameter Values.

For example, for table checkpoints you can set cell values as regular

expressions, and for XML checkpoints you can set attribute or elementvalues as regular expressions. For more information on specific checkpoint

types, see the relevant chapter for the checkpoint type.


21/25

Defining Regular ExpressionsYou can define a regular expression for a constant value, a Data Table

parameter value, an Environment parameter value, or a property value in aprogrammatic description.

You can define a regular expression by entering the regular expression

syntax for the string in the Value box in the Constant Value Options dialog

box or the Parameter Options dialog box. You instruct Quick Test to treatthe value as a regular expression by selecting the Regular Expressioncheck box.

By default, Quickest treats all characters in a regular expression literally,

except for the period (.), hyphen (-), asterisk (*), caret (^), brackets ([ ]),

parentheses (()), dollar sign ($), vertical line (|), plus sign (+), question mark(?), and backslash (\). When one of these special characters is preceded bya backslash (\), Quick Test treats it as a literal character.
