Best Practices for your BPT Framework
BUSINESS PROCESS TESTING
Scenario – Create and Approve •
Consider steps for a creation and approval scenario – Launch –
the application
using customer care id
– Create
a new
–
and close the application
– Launch
the application
–
using id
– Approve –
6
the new
and close the application
Best Practices for your BPT Framework
Typical BPT Design for the Scenario •
Create re-usable components – Launch Application – – Create
– Approve
– – Close Application
7
Best Practices for your BPT Framework
Facts About the Design •
Created 6 reusable components
•
Easy to use and
•
10 components called in the Business Process Test
•
High reusability

Best Practices for your BPT Framework
OPTIMIZING SCRIPTS
Optimizing Scripts •
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
10
scripted components with more flexibility
Best Practices for your BPT Framework
SMART TAGS
Smart Tags •
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

Default Smart Tags 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 datatable parameter

Smart Tag Sample
14
Best Practices for your BPT Framework
Custom Smart Tags •
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
15
Best Practices for your BPT Framework
FLEXIBLE COMPONENTS
Best 16 Practices for your BPT Framework
Flexible Component •
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
17
Best Practices for your BPT Framework
Flexible Component – Perform Launch and If IsParameterSet("bPrevious") Then Call _() End If If IsParameterSet("bClosePreviousBrowser") Then Call _CloseBrowser() End If If IsParameterSet("bLaunchApplication") Then Call _LaunchApplication() End if If IsParameterSet("b") Then Call _() End if 18

Create and Approve – Flexible Components
19
Best Practices for your BPT Framework
Optimizing Existing BPT Scripts 1
Analyze
Analyze existing component usage pattern
20
Best Practices for your BPT Framework
2
Merge
Merge common component pattern calls
3
Unit Test
Test the merged component
4
Update Script
Update scripts to use the merged component
Component Merge Recommendation Tool •
Developed at Infosys, Tool analyses existing BPT scripts and recommends which components can be merged for optimization
•
Sample Graph recommending merging of and Open (84%) components Bad 3% Create 13% Create Open Bad Open 84%
Component Called After - 21
Best Practices for your BPT Framework
Benefits of Component Merging •
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
Best 23 Practices for your 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 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
all Components to Local directory
Resolves shortcircuiting of parameters
Combines all component code into single component
Generates a notepad file
Converted Code from BPT to QTP Script bLoadSession = False Dim Parameter, LocalParam 'Code for Business Component - Perform Launch or ExecuteGlobal StartComponent("Perform Launch or ") 'Parameters for the Business Component - Perform Launch or Parameter("bPrevious") = "FALSE" ….. Call EndComponent("Perform Launch or ") 'Code for Business Component - Create 'Parameters for the Business Component - Create …. Call EndComponent("Create “)
25
Best Practices for your BPT Framework
Benefits of Conversion to QTP Script •
Faster execution of scripts (20% - 50% faster)
•
Easy to debug scripts
•
Capability to resume scripts from any component, re the run-time parameter values of last run using external XML file
