The document discusses acceptance test-driven development (ATDD) and behavior-driven development (BDD) using the Cucumber framework with Selenium. It provides an overview of Cucumber features like tags and scenario outlines. It then demonstrates how to set up a simple Cucumber and Selenium project in Maven including dependencies and feature files. Finally, it introduces the Automotion Responsive UI Validator for validating responsive design and visual elements in acceptance tests.
Smart acceptance GUI tests with Selenium
- 1. Smart acceptance GUI tests with Selenium >Denys~Zaiats
- 2. Agenda 1. Introduction into ATDD (BDD + Specification by example) and Cucumber. 2. Simple usage of Cucumber with Selenium. 3. Reporting as an important part of acceptance tests. 4. Smart UI testing.
- 3. What the software testing is? Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not. Criterias of good tests: ● Highly accurate ● Easy maintainable and readable ● Good results
- 4. Highly accurate tests 1. Using auto-generate strings with special symbols 2. Always to have different values for usernames and passwords 3. Test boundary and middle values. (e.g: 0..100: -1, 0, 1, 25, 63, 99, 100, 101 ) 4. Represent real business / user flow in the tests 1. Using simple hardcoded strings for verification like “abcd” or “1234” 2. Using username: test123 and password: test123 3. Skipping the testing of boundary values 4. Jumping between the steps using tricky navigation
- 5. Easy maintainable and readable tests Scenario: Verify that main logo is displayed When user navigates to 'https://www.facey.top' Then page is displayed correctly And language of the page is 'en' driver.get(“https://www.facey.top”); driver.findElement(By.id(“someId”)).isDisplayed() ; … function test(){ ... some function for verification of the language on the page ... }
- 6. Good results Loading... Test set: runner.RunnerMathTest ------------------------------------------------------------------------------- Tests run: 8, Failures: 2, Errors: 0, Skipped: 0, Time elapsed: 19.809 sec <<< FAILURE!

- 7. Definition “ATDD (Acceptance test-driven development) is a development methodology based on communication between the business customers, the developers, and the testers. ATDD encompasses many of the same practices as Specification by Example, Behaviour Driven Development (BDD), Example-Driven Development (EDD), and Story Test-Driven Development (SDD). All these processes aid developers and testers in understanding the customer’s needs prior to implementation and allow customers to be able to converse in their own domain language. ATDD is closely related to Test-Driven Development (TDD). It differs by the emphasis on developer-tester-business customer collaboration. ATDD encompasses acceptance testing, but highlights writing acceptance tests before developers begin coding.” (from Wikipedia)
- 11. BDD frameworks for Java Cucumber Concordion JBehave Spock (groovy) Easyb (groovy)
- 12. Example of Feature file Not very clear scenario: When user click on button Then everything works
- 13. Selenium + Cucumber: how to start?
- 14. What You need to know about Cucumber 1. Maven dependencies to Cucumber 2. Feature file under “src/test/resources/../features/../” 3. Cucumber test runner 4. Implemented steps
- 15. Step 1. Prepare Yourself. Tools 1. IntelliJ IDEA 2. JDK 1.8 3. Maven 4. Set environment variables for JAVA and Maven (for Windows) 5. Install plugins for IntelliJ “Cucumber for Java” if not installed 6. Ready to go! www.itarray.net - Lesson 1
- 16. Step 2. Maven dependencies 1. What is pom.xml? 2. Required dependencies for Cucumber and Selenium
- 18. Cucumbers features 1. Tags (@Smoke) 2. Scenario outlines (Tables)
- 20. First Selenium scenario ...So, what is Automotion? Possibility to run any of existing web / mobile drivers from one place Useful utils for web and mobile automation: Scrolling, swiping, tapping, waiting, end so on Manipulating by Android settings during test run Validation of the language on web / mobile page Tools for performing REST API testing Testing of responsive design
- 22. Responsive design How to test next things like:
- 23. Existing services - Image recognition (not very effective) - High costs - Not easy integration with existing test framework - Dependendencies to other services - Specific syntax
- 24. What we need? - Easy integration into existing framework - Working with Selenium tests - Readable syntax - Fast and accurate results
- 25. Automotion Responsive UI Validator We can do: - Define approximate or precise values for measuring of the sizes - Offsets and margins - Comparison with offsets of other elements - Overlapping (if inside or outside of specific elements) - Correct alignment - Different units for measuring ResponsiveUIValidator uiValidator = new ResponsiveUIValidator(driver); boolean result = uiValidator.init() .findElement({rootEelement}, "Name of element") .sameOffsetLeftAs({element} "Panel 1") .sameOffsetLeftAs({element} "Button 1") .sameOffsetRightAs({element} "Button 2") .sameOffsetRightAs({element}, "Button 3) .withCssValue("border", "2px", "solid", "#FBDCDC") .withCssValue("border-radius", "4px") .withoutCssValue("color", "#FFFFFF") .sameSizeAs({list_elements},) .insideOf({element}, "Container") .notOverlapWith({element}, "Other element") .withTopElement({element}, 10, 15) .changeMetricsUnitsTo(ResponsiveUIValidator.Units.PERCENT) .widthBetween(50, 55) .heightBetween(90, 95) .drawMap() .validate(); uiValidator.generateReport();

Editor's Notes
- #3: Today I will show You some screenshots, charts, videos and live examples.
- #4: Ask about is people agree with it. If not - ask why.
- #7: Ask people if they like it and if they do the same reporting on the project
- #8: Joke about many text.
- #17: Pom file is the main Maven file that defines how we want to run maven goals, which dependencies to use.
