Presentation about how to use REST, Web and Mobile open source tools to increase your test codebase. This presentation was made by me and Edson Yanaga for JavaOne 2017 San Francisco on 04/09/2017

4. Intermediate validation
between back and front end
Test in REST service
To guarantee stability during
continuous test cycles
Mock in REST service
Functional and Acceptance tests
on Mobile UI
Test in Mobile UI
Functional and Acceptance
tests on Web UI
Test in Web UI
TOOL BOX
The correct toolbox is a key in a automation process

5. REST API
Our API “documentation” (you may use swagger)
ExampleURLVerbAction
/api/v1/person/api/v1/personGETList persons
/api/v1/person/27/api/v1/person/:idGETGet person by id
/api/v1/person/api/v1/personPOSTCreate a person
/api/v1/person/33/api/v1/person/:idPUTUpdate a person by id
/api/v1/person/52/api/v1/person/:idDELETERemove a person by id

6. REST SERVICE AUTOMATION
One of the most important layer
Have same importance as UI has
Always assert business transactions
On new services, try do validate manually first
CURL (CLI)
PostMan (Standalone application | Google Chrome extension)

7. MOCK FOR REST TESTS
The easiest way to create mocks for test
Microframework with Java 8 power
Great choice for micro services
Easy REST implementation to create you own mock with real response
http://sparkjava.com

8. MOCK FOR REST TESTS
Because you will not test in production (all the time), right?
Mock example with fixed data
Using fixed data is a good solution to test with a
real data (req, res) without code changes

9. MOCK FOR REST TESTS
Mock example with dynamic data
Create a list of pre-defined data may be a good way to
manage the testing data
Because you will not test in production (all the time), right?

10. REST
ASSURED
Easy DSL for REST service automation
Uses the give-when-then (BDD) syntax
https://github.com/jayway/rest-assured

11. WHAT I NEED?
What is needed to create a REST test automation with RestAssured
Import some static classes
Set the base URI, base path and port (if needed)
import static io.restassured.RestAssured.*;
import static org.hamcrest.Matchers.*;
baseURI = "http://localhost";
basePath = "/api";
port = 4567;

12. REST TEST AUTOMATION
You need do set the URL, path and port
Before and After (setup | tearDown) for each tests
A good solution to start and stop your API mock
server using Spark

13. RestAssured has a fluent API to automate REST tests
RestAssured test example
Sending a GET with id 1 (given) and the assert
the response/results (then)
REST TEST AUTOMATION

14. SELENIUM
WEBDRIVER
Browser automation API for real browsers (including IE)
Can be controller by many programming languages
http://seleniumhq.org
W3C
Simulate an real user on browser

15. WHAT I NEED?
What you need to create your first web test with Selenium
Web browser and a driver*
A browser to use the inspect tool (native function in various browsers)
[ProTip] Use any software to change internet speed
* you will need a proper driver (executable file) to each browser

16. INSPECT AN WEB ELEMENT ON A BROWSER
A way to get the find an element for future utilization
Inspect
button

17. PROCESS TO CREATE WEB TEST SCRIPT
Easy process to create all yours web test scripts
Selenium test
script creation
process
Browser initialization and
navigation control
(back, forward, refresh)
Navigation
A way to find a web element
id, name, cssSelector, xpath
Interrogation
Wait for dynamic elements or
some asynchronous request based
on web elements
Synchronization
A way to interact with the web elements
click, clear, sendKeys, getText
Manipulation

18. WEB TEST AUTOMATION
Selenium has an easy DLS
Selenium Automated test
Complete example with navigation, interrogation, manipulation and synchronization

19. 1

Use Page Objects to create modular test scripts
Apply design patterns in your test codebase
Execute web test in different internet speeds
Use XPATH only when needed
PRO TIPS FOR WEB TEST AUTOMATION
For a more professional test script

20. PRO-TIPS FOR YOUR WEB TEST SUITE
Is really important divide your tests into onto suites grouped by test levels
HEADLESS TEST ACCEPTANCE TEST FUNCTIONAL TEST
AUTOMATION TEST SUITE
1 2 3 4
GIVE FAST FEEDBACK FOR CONTINUOUS TEST CYCLES
TEST THE SYSTEM IN A USER PERSPECTIVE
TEST WITH A BUSINESS RULES PERSPECTIVE

21. APPIUM
API for automation on mobile devices
Android and iOS supported
http://appium.io
Execution on emulators, devices our cloud
Test on native or hybrid apps

22. WHAT I NEED?
Pre-reqs to create an automated test for mobile with Appium
Android SDK
Appium (via Appium.app or Nodejs)
Configure your path with (tools | platform-tools | tools/bin)
SDK Platform + System Image (to the emulator)
Emulator or Real Device

23. INSPECT COMPONENTS
You can inspect na component using uiautomatorviewer
Inspect
button
Inspected
component
Component
attributes

24. PROCESS TO CREATE MOBILE TEST SCRIPT
Easy process to create all your mobile test scripts
Appium test
script creation
process
Capabilities like Platform, Version,
Target app and others
DesiredCapabilities
Start the session between Appium
and Device (Appium.app or Nodejs)
Session
Wait for async requests basing on
components wait
Synchronization
The same way we do with Selenium
Find and interact with components
Interrogation and Manipulation

25. MOBILE TEST AUTOMATION
Despite of DesiredCapabilities and Session, is the same Selenium script
Example with a pre-installed app
Complete example targeting an Android platform

26. PRO TIPS FOR MOBILE TEST AUTOMATION
For a more professional test script
1

4
Execute tests with fresh and pre installed app
Create a test suite with user focus
Test on other networks(Wi-Fi, 3G…)
Test non-function req.
