Test Automation Approach
The Test Script Modularity Framework
The Test Library Architecture Framework
The Keyword-Driven or Table-Driven Testing
The Data-Driven Testing Framework
The Hybrid Test Automation Framework
Test Automation Framework
The most commonly implemented framework is a
combination of all of the above techniques, pulling
from their strengths and trying to mitigate their
NexOS Test Automation Framework (Hybrid) =
Test Script Modularity / Test library Framework
The DataDriven Testing Framework
Test Script Modularity Framework
The test script modularity framework requires the
creation of small, independent scripts that represent
modules, sections, and functions of the application-
These small scripts are then used in a hierarchical
fashion to construct larger tests, realizing a particular
Test Library Architecture Framework
The test library architecture framework is very similar to the test
script modularity framework and offers the same advantages, but
it divides the application-under-test into procedures and functions
instead of scripts.
This framework requires the creation of library files (SQABasic
libraries, APIs, DLLs, and such) that represent modules,
sections, and functions of the application-under-test. These
library files are then called directly from the test case script.
This is incorporated in NexOS Project by creation of Business
functions which are specific to partition/workspace/reveal in vbs
files and NexOS,generic / Global functions (for each web
Object). which are used as libraries.
VBS files for Partitions
Partition in NexOS Library file
Each .vbs file has the functions defined for that particular
Data-Driven Testing Framework
Data-driven testing framework is incorporated in
NexOS Project by inputting the data into an Excel file
and importing the values into QTP Data table at the
time of execution.
Enables to test the application with multiple sets of
Environment Variables (read only data) are declared
in Config.ini file
Following are the Environment variables:
The user id, password (encrypted) and environment
(URL) and the Host Name are driven from the
Login_Config.xls file attached to the config folder in
the QC test plan
Default URL i.e., http://originationit will be taken if
there is no entry for the URL and the QC User Name
will be taken to login to the application if there is no
userId Provided in the Login_Config.xls file
Test Plan consists of three main folders:
Development contain scripts under construction
Handoff are scripts delivered to client.
Performance are scripts modified
for stress testing.
Each folder structure contains:
Test Plan Structure
Config: Configuration file has the environmental variables of
URL, Userid, Password, Pool, AccessResultsLocation path,
Login config path, Screenshot root path, POS validation and
Take Screen shot.
Documents: Documents folder contains all documents required
for preparation and understanding of the NexOS Automation
LIB: Contains Business Library and Global Library Functions
located in the form of vbs file
OR: Contains object repository files attached in the Attachment
section. Object Repository is used in Login part of the
application, because some win objects are not identified by the
descriptive programming or takes more time to identify. The file
is saved in .tsr( Test Shared Repository) extension.
Test Plan Structure (continued)
Recovery: Contains some attachments for Recovery Scenarios
in .qrs(Quick Test Recovery Scenario) and .vbs files are attached
in Attachment section
Scripts: Contains Integration and POS folders, where integration
folder contains Test set folder, in Test Set Process Flow folder
wise is divided, respected test scripts and the Smoke Test
Cases. Each test script has its own test data attached in the
attachment section. POS folder contains all the pos test scripts
and the test data attached to the Attachment section.
The Test Scenarios in NexOS automation Project are divided
into different Test Sets, each Test Set contains 10 Process
Flows, each flow contains different Test scenario Scripts, for
each script test data is attached in the Attachment section.
Test Set (X)->Process Flow (X)->Test Script
Handoff and Performance Folder
Folder structure is same as the structure mentioned above
(i.e. Config, Documents, LIB, OR, Recovery, Results and
Process of delivering the scripts is a folder is created with a
date 2007_11_15(start date of deliverables).
These set of scripts were to support performance testing
team and returns the page rendering time.
Script Components Guideline
When the script is developed and ready for execution,
follow the guidelines given below:
Connect to Quality Center.
Ensure that Test Data (Excel sheet) is attached
to the Test Script.
Add all the Library files required for test
execution in LIB.
Add Configuration file in Config folder.
Add Object Repository file in OR.
Script Execution from Test Lab
Go to Test Lab in Quality Center
Select the required test from the execution grid and
click on Run button on the header,
Select the required host for execution and again click
on Run button in the Pop up window
Quality Center will initiate QTP and executes the
Click on Run Test Set button in order to run the entire
Test Results are of two types:
2) Screen shots
Reporting - Test Results are stored in two places.
Microsoft Access (Database)
Test Lab in Quality Center.
Storing Results in Access and QC
Tracking Results in MS-Access:
All the Verification points in each script are stored in the
Respective Table of the MS-Access. Results can be tracked at
the following location which can be configurable from the
Test Lab in Quality Center:
Go to Test Lab Tab in the Quality centre
Double click on the script executed in the Execution grid
Double click on the Run Name in the Test instance Properties
Verify the results in the Run Steps Dialog box
