selenium testing best practice

1. how to select test cases to automate?

• how does business make money?
• how do users use your application?
• what browsers are user using?
• what things have broken in the past?

2. type of automation framework

• module based
• data driven
• keyword driven (table lookup)
• bdd (cucumber, jbehave)

3. page object model

• single place for the service offered by the page
• clean separation between test code and page specific code

4. page factory

• a class provided by selenium webdriver to support page object model
• allow testers use @FindBy annotation
• use the initElements method to initialize all the web elements located by @FindBy

5. avoid thread.sleep, prefer wait

    (new WebDriverWait(driver, 30)).until(new ExpectedCondition() {
                public Boolean apply(WebDriver d) {
                    return d.getTitle().toLowerCase().startsWith("java developer")             
    }

6. hrm modules

• users
• payroll
• personal information
• leave and timesheet
• recruitment
• performance
• training

7. ecommerce modules

• customer registration and account management
• product catalog
• orders and payment
• coupons
• store locator
• invoice and receipt

8. do not use try/catch in bdd code

• so that test will fail-fast (any run-time exception will terminate the step/step definition)

9. visual testing using blue-harvest

10. common issues

• handle UnexpectedAlertOpenError in protractor
• headless mode

11. open new page

• click something to open
• findInteractableWebElement on the new page (to know that new page is open)
