BDD is a process that improves communication between engineers and business teams to ensure development projects deliver the required functionality and meet user needs. UI automation best practices include using page object patterns to abstract element locators, writing user stories in Cucumber, and selecting element locators by data attribute, ID, then CSS before using XPath. Tests should cover user interactions, business logic, modules, and stories with screenshots on failures.

Best practices and Patterns

2. Overview
BDD is a process designed to aid the management and the delivery of software
development projects by improving communication between engineers and business
professionals. By aiding communication between these two teams, BDD ensures all
development projects remain focused on delivering what the business actually needs
while meeting all requirements of the user.

5. What to cover
Item 3
● End to End tests / E2E
● User interactions and business logic
● Self-contained modules
● User stories

6. Best practices
● PageObjects pattern
● User stories / Cucumber scenarios
● Selector order: data > id > css > xpath
● Relative URLs
● Creta datasets
● Make Screenshots on failures

7. Page Objects
Item 3
AbstractPage
- getUrl()
- validatePage()
- clearCookies()
- navigate()
HomePage
- getTopSearchBox()
- getLoginForm()
- getRegistrationForm()
- validate()
OrdersPage
- getOrdersList()
- getPendingOrdersTable()
- validate()

8. User Stories

9. Element selectors
Item 3
div#main div.full-height-page div#plans-compare div.container section.plans-section.plans-section--
api div.col-l-3.col-ie-3 a.button
CSS

10. Element selectors
Ex 1: /html/body/div[1]/div[2]/div/div/div/div/section[3]/div[2]/a
XPath
Ex 2: //div[@id="myid"]//div[@class="myclass"]//p[text()="found my text"]

11. Element selectors
Item 3
[data-qaid=video-box]
Data attribute
ID attribute
#video-box

12. Problems to overcome
Item 3● Prepare testing DB with preset datasets
● Access external APIs
● Run tests under different browsers (IE, FF, Chrome,
Safari)
● Run tests for different screen dimensions
