This document describes a Webdriver Enhanced Platform for Automation (WEPA) framework for automating web application testing using Selenium. It discusses why a framework is useful for standardizing test artifacts, scripts, and classes to make tests reusable across projects, easy to maintain and extend. The framework uses Selenium scripts in Perl, a database to store test data and results, and a grid to run tests in parallel on multiple browsers and machines. It provides layers for test execution, functional actions on the application under test, and system services like the database. Configuration files are used to specify test browsers, platforms, and data.

2. SUMMARY
• FRAMEWORK? WHY?
• WHAT TO INCLUDE
• HOW IT WORKS
• HOW TO SCALE IT

3. WHY USE A FRAMEWORK
• STANDARD NOMENCLATURE
• TEST ARTIFACTS (SCREENSHOTS, LOG FILES)
• TEST SCRIPTS
• TEST CLASSES
• REUSABILITY (SAME FRAMEWORK DIFF PROJECTS)
• EASY TO MAINTAIN
• EASY TO EXTEND
• EASY TO UNDERSTAND

4. SYSTEM COMPONENTS
1. TEST SCRIPTS (SELENIUM)
2. AUT DRIVER (SELENIUM SERVER)
3. PERL
4. DATABASE

5. SYSTEM DIAGRAM & WORKFLOW

6. TEST SCRIPTS
• Coded in Perl
• Cross platform
• Use page objects
• Based on a standard
template

7. TEST SCRIPT TEMPLATE
• PLATFORM LOOP
• BROWSER LOOP
• TEST DATA LOOP
• SETUP TEST
• RUN TEST
• CLEANUP TEST

8. THE GRID
• Java (jar file)
• Selenium Stand Alone Server
• Can be launched in two modes / roles
• Hub
• Node
• Adds the capability to run tests in Parallel
GRID1

9. AUTOMATION DB
• MySQL
• Test Data
• Form Field Data
• HTML Element Object Map
• Test Pages (URLs)
• Keyword / Actions
• Test Artifacts
• Test Runs
• Results (pass/fail)
• Screenshots

10. SYSTEM COMPONENTS BLOCK DIAGRAM

11. TEST EXECUTION LAYER
• FACES THE USER (SCRIPT PROGRAMMER)
• COMMUNICATES WITH FUNCTIONAL LAYER
VIA EXPOSED METHODS (ACTIONS):
• LOAD_TEST_DATA
• LOGIN_AS
• ADD_ITEM
• EDIT_ITEM
• DETERMINES PASS / FAIL STATUS
• TEST.PL

12. • Only layer that “speaks AUT”
language
• Drives the AUT (by executing
actions)
• All actions to be performed on
AUT are defined here
• Utilizes System Layer as
needed
• Returns 1 or 0 to Test
Execution layer
1 = success
0 = unsuccessful
• WepaApp.pm
• ShoppingCart.pm
• SettingsModule.pm
FUNCTIONAL LAYER

13. • Interface with anything that is
not AUT
• Provides Services for the other
layers
– DB access
– Write and Parse Log Files
– Test results processing
• WepaSubs.pm
SYSTEM LAYER

14. TEST BREAKDOWN
• ONE
WEPA<AREANAME>.PM
FOR EACH APPLICATION
FUNCTIONAL AREA
• INHERITS BASE ACTIONS
FROM WEPAAPP.PM (THE
FUNCTIONAL LAYER’S
MAIN CLASS)

15. TEST CONFIGURATION
• INI type configuration files
• Test Browsers (FFX,
CHR, IE, SFR)
• Test Platforms (Win7,
Win8, MAC)
• Test Information
• Test Data
• Configuration File is loaded
when the test runs

16. SYSTEM REQUIREMENTS
• WebDriver itself does not have any system requirements
• Requirements will depend on numerous factors:
• Total number of tests
• Number of physical machines (PC’s)
• Complexity of the tests
• Type of test (end-to-end, regression)
• 12 Browsers per WebDriver node (VM)
• 2 GB RAM
• ~1.5 – 2GHz Processor
General Guideline

17. VIRTUALIZED
EXECUTION
ENVIRONMENT
• 6 VIRTUAL
MACHINES
• 11 BROWSERS /
