Qtp Testing Day3

QTP – Check Points  A checkpoint is a verification point that

compares a current value for a specified property with the expected value for that property.  This enables you to identify whether your Web site or application is functioning correctly.  When you run the test, Quick Test compares the expected results of the checkpoint to the current results. If the results do not match, the checkpoint fails. CIBC - Testing

QTP – Check Point Types  Bitmap Checking - You can check an area of a

Web page or application as a bitmap. While creating a test, you specify the area you want to check by selecting an object. You can check an entire object or any area within an object.  Standard Checking - You can check use standard checkpoint to check the text property of an object. This is the preferred way of checking text in many Windows applications.

QTP – Check Point Types  Text Checking - Enables you to check

that the text is displayed in a screen, window, or Web page, according to specified criteria. It is supported for all environments.  Text Area Checking - Enables you to check that a text string appears within a defined area in a Windows application, according to specified criteria. It is supported for Standard Windows, Visual Basic, and ActiveX environments. CIBC - Testing

QTP – Check Point Types  You can use database checkpoints in your

test to check databases accessed by your Web site or application and to detect defects. You define a query on your database, and then you create a database checkpoint that checks the results of the query.  Two ways to define database query are Microsoft query and SQL query.

QTP – Analyzing Check Points in Test Results  Check points Pass/Fail Criteria can be

clearly viewed in the Test Results.  Test Results Tree Structure will clearly display the Expected and Actual Check points or Objects.

QTP - Parameterization  Constant—A value that is defined directly within

the test or component and remains set for the duration of the test or component.  Parameter - A value that is defined or generated outside the test or component and is retrieved when the specific step runs. 



A parameter is a variable which replaces a recorded value in the script. At run time, QuickTest substitutes a value from a data source for the parameter.

QTP – Data Driven Test  A Test/Script that runs one set of user actions

with multiple input values.  Data Driving allows one script to test AUT functionality with many sets of data.  Data Source The location of data that QuickTest will use to supply the parameter. In QuickTest, the data source is called the Data table. The Data table is a spreadsheet file that contains input values for a data driven test. CIBC - Testing

QTP – Benefits of Data Driven Test  Increased Test Coverage.  Test Boundary Conditions.  Test Valid and Invalid data.  Test different tables in the database.

QTP- How Data Driven Test Works  Parameter(s) replace recorded input data.  Data table references tell QuickTest where

to get data for the parameter(s)

QTP – Regular Expression  Regular expressions enable QuickTest to

identify objects and text strings with varying values.  Examples for Regular Expressions are, - Creating checkpoints with varying values. - For example, you can use a regular expression if you want to create a text checkpoint on a Number text string, but the displayed Number changes according to the current updations. CIBC - Testing

10

QTP – Regular Expression  If you define the number as a regular

expression, the checkpoint checks that the captured text string matches the expected numbers format, rather than checking the exact number value.  You can use Regular Expressions only for values of type string.
