#1 - Working with frames.
#2 - Working with tabs/windows.
#3 - Taking screenshots on failures.
#4 - Waits.

“Automation with frames is not trivial, In order to
access the elements within a frame we need to tell
Selenium to switch to it”
driver.switchTo().frame(“iframe”);
• Nested frames requires harder work:
ie. accessing /Level1/Level2/…/LevelN
driver.switchTo().frame(“Level1”);
driver.switchTo().frame(“Level2”);
etc…
driver.switchTo().frame(“LevelN”);
• Switching back if accessing outside the frame:
driver_.switchTo().defaultContent();

“The same as with frames, when new window/tab
created in browser we need to tell Selenium to
switch to it”
driver.switchTo().window(newWindowHandle);
• To identify new window we take list of windows
handles and subtract it from the old list before
new window was inserted.
SetString newHandles = driver_.getWindowHandles();

“Taking screenshots is one of the basics in automation to
understand whats’ failed”
• Prefer to set screenshot taking in base class.
• Take screenshots only on failures.
(Unless there is real need i.e. UI Automated Testing)
• Preserve order in naming so it will easy to find the images.
((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

7. 9CKVU
“Wait are usually required for synchronization with the
Application under test (AUT)”
• Implicit wait - The amount of time given to findElement
method before it fails (Raise an Exception)
Note: There default implicit wait in Selenium is 0
driver.manage().timeouts().implicitlyWait(4, TimeUnit.SECONDS)
• Explicit wait - Polling mechanism to fulfil a condition
within a given timeout.
(new WebDriverWait(driver, 10)).until(Condition);
*Condition can be either one of builtin ExpectedConditions or Custom
predicate.
