Jorge Hidalgo

This document provides 9 tips for using Selenium best practices and patterns for testing Java applications. It discusses using JSON for configuration, managing nodes with VisGrid, creating an ephemeral grid, managing driver binaries with WebDriverManager, alternatives to XPath such as providing predictable IDs, using the ISelect interface effectively, how the Action Builder can help, continuous testing for microservices using Jenkins as an orchestrator, and considering Selenium tests as their own application. Credits are provided for related GitHub repositories and a previous presentation on the topic.

#TIP 3: CREATING AN EPHEMERAL GRID Copyright 2017 Accenture. All rights reserved. 8
#TIP 3: CREATING AN EPHEMERAL GRID Copyright 2017 Accenture. All rights reserved. 9 YOU CAN CONFIGURE AND LAUNCH NODES FROM YOUR CODE • Add the Selenium Server dependency to your POM
#TIP 3: CREATING AN EPHEMERAL GRID Copyright 2017 Accenture. All rights reserved. 10 Use the GridLauncher to create server instances with different roles
#TIP 4: MANAGING DRIVERS BINARIES WEBDRIVERMANAGER Copyright 2017 Accenture. All rights reserved. 11

#TIP 4: MANAGING DRIVERS WITH WEBDRIVERMANAGER Copyright 2017 Accenture. All rights reserved. 13 Add the dependency Use the DriverManager
#TIP 4: MANAGING DRIVERS WITH WEBDRIVERMANAGER Copyright 2017 Accenture. All rights reserved. 14 Fully configurable using the API Or parameters
#TIP 5: XPATH IS NOT UNDER YOUR CONTROL Copyright 2017 Accenture. All rights reserved. 15
XPath usage in Selenium depends on: Native capabilities for XPath of each browser If not available, Selenium provides its own implementation #TIP5: XPATH IS NOT UNDER YOUR CONTROL
An example from the Selenium documentation #TIP5: XPATH IS NOT UNDER YOUR CONTROL
COROLLARY: NEVER, NEVER USE XPATH Using XPath for interacting with your web is not a PREDICTABLE nor REPEATABLE approach.
#TIP 6: ALTERNATIVES: PROVIDE PREDICTABLE ID TO YOUR WEB ELEMENTS Copyright 2017 Accenture. All rights reserved. 19
Instead of investing a lot in creating highly complicated ways to interact with the elements in your application, consider change the application instead - Overriding ID of your web elements - Creating anchor elements that helps on accessing your elements #TIP6: ALTERNATIVES: PROVIDE PREDICTABLE ID TO YOUR WEB ELEMENTS
COROLLARY: THINK ON TESTABILITY One of the drivers when you define your web framework should be the ability to test the application
#TIP 7: USING API EFFECTIVELY: THE ISELECT INTERFACE Copyright 2017 Accenture. All rights reserved. 22
The ISelect Interface provide methods to interact with elements of type Select. The Select implementation provides methods for: • Select (by Index, by Value, by Text) • Deselect (All, by Index, by Value, by Text) Works with MultiSelect #TIP7: USING API EFFECTIVELY: THE ISELECT INTERFACE
#TIP 8: THE ACTION BUILDER CAN ALSO HELPS Copyright 2017 Accenture. All rights reserved. 24
We are using Selenium to emulate human interaction with the application under test The Action Interface Builder can be useful when try to explicitly guide the interaction through your web page #TIP8: THE ACTION BUILDER CAN ALSO HELPS
#TIP 9: CONTINUOUS TESTING FOR MICROSERVICES Copyright 2017 Accenture. All rights reserved. 26
Jenkins as Orchestrator CONTINUOUS DELIVERY PIPELINES Copyright © 2017 Accenture. All rights reserved. 27 Test scope is limited to one service/app Test scope is end-to-end
Jenkins as Orchestrator CONTINUOUS DELIVERY TRIGGERS Copyright © 2017 Accenture. All rights reserved. 28 Trigger on code/config/test change Tests are in the same code repo Trigger after any component is promoted and deployed Trigger on end-to-end test change End-to-end tests (and test data) are in separate code repo May reuse tests from components
corollary: consider it as an application When you are using Selenium you are creating an application to test your application
