–Test Automation is Software Development
–End-to-End Tests are slow

–Perfect vs. Good Enough – A Context where
Time to Market Matters

CLIENT
•Is seen as „Selenium“ by the users
•Is called by the test framework or the CI server

•Generates HTTP requests which are received by the
server

•Supported languages:
Java, C#, Python, Ruby, PHP, JS


12

SERVER
•Receives HTTP requests
•Start and teardown of browser

•Translates requests into browser specific commands
•Communicates back to the client

• Elements are found by locators
• Found element are used for different
interactions
• Example

BORDERLESS TEST AUTOMATION
•Our business is borderless  test automation needs
to be as well

•Use the same approach and infrastructure for web
and mobile


32

SAME API FOR WEB AND MOBILE
A regular Web Test Case

An iPhone app test

An Android app test
