3. When there are no problems nothing should be done
LETS START WITH PROBLEMS!

4. Endless regression testing

5. Duplicated efforts on tests
WebDriver
Test
=
Test Case

6. Everybody do manual tests
Developers
QA engineer
Customer

7. TDD is very simple concept but at the same is very hard to do
TDD WITH WEBDRIVER

8. TDD is simple cycle

9. Acceptance TDD approach
Automated
Acceptance
Acceptance Tests
criteria
Analysis

Implementation

Automated
Acceptance Acceptance
Tests criteria

10. WTF?!?
Write tests before
UI is ready?
Impossible!!!

11. WebDriver test components
Get Driver
Use Driver
Provide Data
Use Locators

12. How to provide data?
Customer Whole team
Acceptance
+ Criteria
Customer QA engineer
Acceptance Behavior
+ Tests Samples
Whole team
Functional Unit Integration
Tests Tests Tests

13. How to use locators?
Discuss page
Use mockup tools structure in details
Developer HTML mockup
starts from HTML from web designer

14. Locators team conventions
Controls by ID
Form elements
by name
Links by
text
List of items
(semantic classes)

15. Natural test parts separation
To enable reliable stable tests we need to
separate all parts as much as possible
Reliability
Clarity
Test Test
Data Logic
Flexibility
Application Maintainability
Driver
Stability

16. Team can be balanced

20. TDD can not only solve current issues but bring you to the next level
BENEFITS AND SUMMARY

21. Way to success is hard
1. Agree on team rules 2. Break your mind
3. Prepare to many issues 4. Relax in TDD environment

22. It is hard! What
are the benefits?

23. Specify how IT MUST WORK,
not how IT WORKS

24. Design with testability in mind
No rework
Less
mistakes Strong
guidelines
Discuss
design early Good
Testable locators
design
Easier tests

25. Less technical tests
Easy to
Clear Readable
maintain

26. Reduce manual checks

27. Clear Definition of Done
@Ignore tests VS iteration test suite

28. Shared
responsibility
for testing
is built
