Let’s go Selenium • Page class abstracts away the Web. Driver for child pages • Web. Driver is initialized once and not passed around in constructors • Awaitility is a cool tool © 2018 NTT DATA Corporation 5

• Too much initialization • Every Object needs to be initialized explicitly • Order of initialization in tester’s responsibility • Web. Driver configuration is in the Test’s responsibility © 2018 NTT DATA Corporation 6

Spring Boot to the rescue • Initialization of objects taken care of by Spring Boot • Configuration handled via application properties files • @Post. Construct for one-time initialization tasks © 2018 NTT DATA Corporation 7

The new and revised Test Framework • Spring Boot Application • Deployable unit • Runs in the virtual cluster of the Backend being tested • Rest endpoint for starting test execution © 2018 NTT DATA Corporation 11

Farewell Selenium. Hello REST API! • Selenium tests are a, very slow, magical thing • Rest API tests, not magical, but very fast • Rest API offers more than just Frontend uses © 2018 NTT DATA Corporation 12
