BUSINESS PROCESS TESTING

Page 6: Tarun Lalwani - Best Practices for Your HP BPT Framework

Scenario – Create and Approve User

6 Best Practices for your BPT Framework

• Consider steps for a user creation and approval scenario– Launch the application

– Login using customer care user id

– Create a new user

– Logout and close the application

– Launch the application

– Login using admin user id

– Approve the new user

– Logout and close the application

Page 7: Tarun Lalwani - Best Practices for Your HP BPT Framework

Typical BPT Design for the Scenario

7 Best Practices for your BPT Framework

• Create re-usable components– Launch Application

– Login

– Create User

– Approve User

– Logout

– Close Application

Page 8: Tarun Lalwani - Best Practices for Your HP BPT Framework

Facts About the Design

8 Best Practices for your BPT Framework

• Created 6 reusable components

• Easy to use and remember

• 10 components called in the Business Process Test

• High reusability

OPTIMIZING SCRIPTS

Page 10: Tarun Lalwani - Best Practices for Your HP BPT Framework

Optimizing Scripts

10 Best Practices for your BPT Framework

• Scripts can be optimized in different ways– Reducing unnecessary parameters (run-time or hardcoded)

– Reducing test data needs using concepts of Smart Tags

– Reducing # of components required to implement scripts

– Creating scripted components with more flexibility

Page 11: Tarun Lalwani - Best Practices for Your HP BPT Framework

SMART TAGS

Page 12: Tarun Lalwani - Best Practices for Your HP BPT Framework

Smart Tags

12 Best Practices for your BPT Framework

• Smart Tags are special tags used for data generation

• Developed at Infosys, not provided by the default BPT framework

• Allow creating dynamic data at run-time

• Eliminates the need to update input data in certain scenarios

• Parsed and converted to actual value by component

• Can be combined with static text

• Multiple Tags can be used for the same parameter

13 Best Practices for your BPT Framework

Smart Tag Usage Description

#NOW##NOW# - Date and time in just numbers (DDMMYYYYHHMMSS)#NOW[Format]# - Date in specified format

Generate the current date and time. Useful for generating unique data records

#RAND[N]##RANDA[N]##RANDN[N]#

#RAND[N]# - N character long random string#RANDN[N]# - N character long random number#RANDA[N]# - N character long random alphanumeric string

Generates random string and numbers

#NEW#

#NEW# - Select a new value. Used for radio buttons, list, checkboxes#NEW[ValueA, ValueB, ValueC]# - Select a new value present in the list

Select a new value always from the control

#ENV[NAME]# #ENV[NAME]# - Read the value from specified environment variable

Read the value from Environment variable

#PARAM[NAME]# #PARAM[NAME]# - Read the value from specified component parameter

Read the value from component parameter

#DATATABLE[NAME]# #DATATABLE[NAME]# - Read the value from specified datatable parameter

Read the value from datatableparameter

Default Smart Tags

Smart Tag Sample

14 Best Practices for your BPT Framework

Page 15: Tarun Lalwani - Best Practices for Your HP BPT Framework

Custom Smart Tags

15 Best Practices for your BPT Framework

• Specific to Application Under Test

• Used to execute flow and capture generated values at run-time

• Example - #NEWCUSTOMER[Tarun,Lalwani]# generates a new customer with the specified first name and last name

Page 16: Tarun Lalwani - Best Practices for Your HP BPT Framework

FLEXIBLE COMPONENTS

16Best Practices for your BPT Framework

Page 17: Tarun Lalwani - Best Practices for Your HP BPT Framework

Flexible Component

17 Best Practices for your BPT Framework

• Instead of building high # of re-usable components build larger flexible components

• Combine commonly performed actions into a single component

• Add Boolean flags to control actions to be performed

• Use functions to perform specific Actions in component

• Use Scripted component instead of Business component

Page 18: Tarun Lalwani - Best Practices for Your HP BPT Framework

Flexible Component – Perform Launch and Logout

18 Best Practices for your BPT Framework

If IsParameterSet("bLogoutPrevious") Then

Call CP_Logout()

End If

If IsParameterSet("bClosePreviousBrowser") Then

Call CP_CloseBrowser()

End If

If IsParameterSet("bLaunchApplication") Then

Call CP_LaunchApplication()

End if

If IsParameterSet("bLogin") Then

Call CP_Login()

End if

20 Best Practices for your BPT Framework

Optimizing Existing BPT Scripts

1 2 3 4Analyze Merge Unit Test Update Script

Analyze existing component usage pattern

Merge common component pattern calls

Test the merged component

Update scripts to use the merged component

Page 21: Tarun Lalwani - Best Practices for Your HP BPT Framework

Component Merge Recommendation Tool

21 Best Practices for your BPT Framework

• Developed at Infosys, Tool analyses existing BPT scripts and recommends which components can be merged for optimization

• Sample Graph recommending merging of Login and Open User (84%) components

Create User13%

Open User84%

Bad Login3%

Create User

Open User

Bad Login

Component Called After - Login

Page 22: Tarun Lalwani - Best Practices for Your HP BPT Framework

Benefits of Component Merging

22 Best Practices for your BPT Framework

• Re-usable components required in the Test suite is reduced

• The flexibility/re-usability remains similar or even higher

• Less components required per Business Process Test

• Reduction in development and maintenance effort

• Reduction in Execution time

BPT 2 QTP CONVERTER

23Best Practices for your BPT Framework

Page 24: Tarun Lalwani - Best Practices for Your HP BPT Framework

BPT 2 QTP Converter• Developed at Infosys, Tool to convert BPT Scripts to a Single QTP Script

• BPT2QTP.QFL to be added to the converted script to support the changes

• Resolves output to input short-circuiting of parameters

• Ability to fetch run-time parameter values directly from Test Set

Select Scripts to be converted

Download all Components to Local directory

Resolves short-circuiting of parameters

Combines all component code

into single component

Generates a notepad file

Page 25: Tarun Lalwani - Best Practices for Your HP BPT Framework

Converted Code from BPT to QTP Script

25 Best Practices for your BPT Framework

bLoadSession = False

Dim Parameter, LocalParam

'Code for Business Component - Perform Launch or Logout

ExecuteGlobal StartComponent("Perform Launch or Logout")

'Parameters for the Business Component - Perform Launch or Logout

Parameter("bLogoutPrevious") = "FALSE"

…..

Call EndComponent("Perform Launch or Logout")

'Code for Business Component - Create User

'Parameters for the Business Component - Create User

….

Call EndComponent("Create User“)

Page 26: Tarun Lalwani - Best Practices for Your HP BPT Framework

Benefits of Conversion to QTP Script

26 Best Practices for your BPT Framework

• Faster execution of scripts (20% - 50% faster)

• Easy to debug scripts

• Capability to resume scripts from any component, remembers the run-time parameter values of last run using external XML file
