SUMMARY

• FRAMEWORK? WHY?• WHAT TO INCLUDE• HOW IT WORKS• HOW TO SCALE IT

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

SYSTEM COMPONENTS

1. TEST SCRIPTS (SELENIUM)2. AUT DRIVER (SELENIUM SERVER)3. PERL4. DATABASE

SYSTEM DIAGRAM & WORKFLOW

TEST SCRIPTS

• Coded in Perl• Cross platform• Use page objects• Based on a standard

template

TEST SCRIPT TEMPLATE

• PLATFORM LOOP• BROWSER LOOP

• TEST DATA LOOP• SETUP TEST• RUN TEST• CLEANUP TEST

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 ParallelGRID1

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

SYSTEM COMPONENTS BLOCK DIAGRAM

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

• 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 = success0 = unsuccessful

• WepaApp.pm• ShoppingCart.pm• SettingsModule.pm

FUNCTIONAL LAYER

• 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

TEST BREAKDOWN• ONE

WEPA<AREANAME>.PM FOR EACH APPLICATION FUNCTIONAL AREA

• INHERITS BASE ACTIONS FROM WEPAAPP.PM (THE FUNCTIONAL LAYER’S MAIN CLASS)

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

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

VIRTUALIZEDEXECUTION

ENVIRONMENT

• 6 VIRTUAL MACHINES

• 11 BROWSERS / VM

• CAPABILITY TO RUN 46CONCURRENT TESTS
