Keyword-Driven Testing

Selenium tests can be con(ured in an external (le.

"his means that a tester can con(ure a set of tests in an Excel sheet )ust by

writin down keywords for each test case alon with any necessary data

without touchin the test code.

*hich in turn means that non+technical testers can con(ure new tests.

"his is called keyword-driven testing.

Data-Driven Testing

# Selenium test suite can be written in such a way as to load data for the test

from an external (le or database.

"his means that testers can control the data that is loaded without touchin

the test code.

*hich in turn means that non+technical testers can create new sets of data

that can result in new types of tests.

"his is called data-driven testing.

Hybrid Testing

eyword+ and data+driven testin approaches can be combined.

"his ives non+technical testers a lot of -exibility to create new tests that

respond to chanes in the software under test.

ut it re/uires an experienced automation enineer to set up the test suite in a

way that minimi0es the amount of technical maintenance re/uired.

"re#uently $hanging %ommer%e Site

Conventional wisdom holds that test automation isn7t worth the investment if

the user interface of your application chanes fre/uently. #nd that7s exactly

why one electronics retailer hadn7t bothered with Selenium automation for their

ecommerce site."he truth has lon since moved on from conventional wisdom.

9sin Selenium and &ava we enerated :E" and $OS" re/uests throuh4""$, parsed the responses and then used Selenium7s native methods for

validatin test results thereby skippin the user interface entirely.

*e set up a series of Excel spreadsheets with loin, credit card, items to

purchase and other details so that testers can chane the automated tests

without havin to edit the test code.

y automatin one level above the user interface and providin an Excel+

based interface for testers, the retailer was able to automate testin while

minimi0in maintenance in a way that did not re/uire fre/uent maintenance by

an automation enineer.

SaaS Web &ppli%ation Testing with Selenium

# software as a service web application provider wanted to automate their

reression test suite to reduce the friction involved in testin and deployin

chanes to their product.

"he e;ort involved in manually runnin their reression testin meant that notall of their builds were bein thorouhly tested before bein pushed out. "hey

hadn7t had any ma)or bus slip into production, but reali0ed that it could

happen at any time.

"he company wasn7t willin to commit the resources to hire a full+time

automation enineer to maintain the test suite either.

# hybrid keyword+ and data+driven testin framework was clearly in order. uteven a hybrid automated solution was oin to re/uire too much maintenance

by an automation enineer to )ustify the expense.

In addition to pullin test scenario and test data de(nitions from Excel sheets

in &ava+based test code, we also abstracted pae ob)ect de(nitions to an

external con(uration (le.

"his allowed testers to update existin tests when user interface elements

chaned, and even create some new tests.

1etailed and summary test reports were enerated automatically ivin

testers, developers and manaers the information they need to act on the

results.
