Timing Issues

Answer 9

Sometimes elements may appear dynamically on the page, you may not know how long they will take to appear. Bad practice is to use something like Thread.sleep(5000);
Good practice would be to use WebdriverWait wait = new WebDriverWait(webDriver, timeout); wait.unit(ExpectedConditions.visibilityOfElementLocated(By.id<locator>));</locator>

Page Object Design Pattern

Answer 10

An abstraction mechanism, consists of creating an object model around your web front end. Makes tests more maintainable and readable. Pass in a WebDriver through constructor, implement methods of interest and use methods in test.
