Study Notes
Selenium WebDriver API Essentials
- Import
org.openqa.selenium.WebDriver
to use the Selenium WebDriver API. - Elements in WebDriver are located using the
findElement()
andfindElements()
methods.
Navigation in WebDriver
- To navigate forward in WebDriver, use the
navigate().forward()
method.
Exception Handling
- When using explicit waits, catch
TimeoutException
to handle when elements take too long to appear.
Wait Types
- Implicit waits are used to define a default waiting time for elements to appear before throwing an exception.
- Implicit waits can be set using
driver.manage().timeouts().implicitlyWait()
.
Driver Details
- The specific driver in use depends on the setup (e.g., ChromeDriver, FirefoxDriver).
- The expected title of the Mercury Tours homepage is typically "Welcome: Mercury Tours".
- The actual title can vary; it needs to be verified through actual execution.
URL and Methods
- The value of the
baseUrl
variable usually corresponds to the homepage URL of the application being tested. - The
get()
method in WebDriver is used to navigate to a specified URL.
Element Manipulation
- The tag name of a specific element can be extracted using the
getTagName()
method. - To find elements by the 'class' attribute, use
findElements(By.className())
. - Locate elements by their tag name using
findElements(By.tagName())
. - Simulate clicking on an element with the
click()
method. - The current page title can be fetched using
getTitle()
.
Window and Frame Management
- To close all windows, including pop-ups, use
quit()
. - Switch to a specific frame using
switchTo().frame()
. - Access the message of an alert box through
switchTo().alert().getText()
.
Wait Declarations
- Explicit waits are typically declared during the instantiation of the WebDriver.
- Import
org.openqa.selenium.support.ui.WebDriverWait
for implementing explicit waits. - For implicit waits,
org.openqa.selenium.WebDriver
must be imported.
Method Functions
- The
get()
method serves to load a new web page in the current browser window. - The
close()
method only closes the current window, unlikequit()
, which closes all associated windows. - Using
System.exit(0)
without closing all browser windows may lead to unexpected behavior since it terminates the JVM without gracefully closing WebDriver sessions.
Element Location and Exceptions
- Use
findElement()
to locate GUI elements. It throwsNoSuchElementException
if the element does not exist. -
WebDriverWait
will throw aTimeoutException
if the element does not appear within the specified timeout.
Navigation Method Differences
-
driver.get()
directly loads a webpage, whiledriver.navigate()
offers additional navigation features (back, forward, refresh). - Both the forward and backward buttons can be used with
driver.navigate()
, whereas withdriver.get()
, they won't function as expected between pages once the page is loaded.
