    Study Notes

    Selenium WebDriver Overview

    • Selenium is an open-source tool for automating web browsers.
    • Selenium WebDriver provides an API in various languages (Java is exampled here) for controlling browsers.
    • Use cases include automated scripts, web scraping, test automation, and performance testing.
    • Selenium's WebElement class facilitates browser actions.

    Setup (Older Selenium Versions)

    • Include Selenium and WebDriverManager dependencies in pom.xml (Example versions provided)
    • Download and include the appropriate browser driver (e.g., chromedriver.exe) in src/main/resources.
    • Manual Configuration (Older Versions): Set system property webdriver.chrome.driver to the driver path.
    • WebDriver Manager (Recommended): Use WebDriverManager to automate driver setup.

    Setup (Selenium 4+)

    • Selenium 4+ version of the dependency does not require manual driver setup.

    Creating a Browser Instance

    • Create a browser driver instance (e.g., ChromeDriver).
    • Navigate to a URL using driver.get("url").
    • Always driver.quit() to close the browser instance.

    Browser Options

    • Use ChromeOptions or similar to configure browser settings:
      • Add arguments like --incognito.
      • Manage profiles.

    Locating Web Elements

    • Selenium's By class provides locator strategies for web elements (e.g., ID, class name, CSS selector).
    • Locator strategies include (but not limited to):
      • class name — Finds elements with the given class name.
      • css selector — Finds elements matching a CSS expression.
      • id — Finds elements with the given ID.
      • name — Finds elements with given name attribute.
      • link text — Finds anchor elements with specified text.
      • partial link text — Finds anchor elements with partial text matches.
      • tag name - Finds elements with the same tag name.
      • xpath — Finds elements matching an XPath expression.

    XPath

    • XPath is a powerful way to find elements.
    • Absolute XPath starts at the top level html/body/div/p.
    • Relative XPath starts from a specific element //div/p.
    • XPath allows various search criteria (text match, functions).

    Driver Interactions: Navigation

    • driver.navigate().back(), driver.navigate().forward(), driver.navigate().refresh() - mimic browser actions.
    • driver.navigate().to("url"); or driver.get("url"); both work identically and save session data, but driver.navigate().to (version-neutral) is more appropriate for maintainability.

    Locating Web Elements (continued)

    • driver.findElement(By.locator) - finds first element matching.
    • driver.findElements(By.locator) - retrieves all elements matching.
    • NoSuchElementException is thrown if no element is found
    • StaleElementException occurs when an element you were previously referencing no longer exists.

    Interacting with Web Elements

    • clear(): removes text from a field.
    • click(): simulates a click.
    • getAttribute(): returns an attribute's value.
    • getText(): retrieves element text.
    • sendKeys(String text): simulates typing text. (file uploads with file paths)
    • submit(): deprecated method to send web form.

    Waits

    • Implicit Waits: a global timeout for element searching (slows down).
    • Explicit Waits: individual, dynamic wait time specified for each element (better management).
      • Use ExpectedConditions class for specific situations (visible, clickable, presence, etc.).
    • Fluent Waits: greater control over wait time, polling frequency, and exception handling.

    Alerts

    • driver.switchTo().alert(): Access the alert dialog
    • Use getText(), sendKeys(), accept(), or dismiss() to interact.

    Actions API

    • Actions(driver): chain together mouse and keyboard actions in a more fine-grained way.
    • moveToLocation(), clickAndHold(), moveByOffset(), release(), and perform() methods create and execute actions, giving better user-level control.

    Screenshots

    • Selenium supports taking and saving screenshots
    • Use the TakesScreenshot interface (casting driver).
    • Save screenshots to a file using the provided interface.

    Windows and Tabs

    • driver.getWindowHandles() returns all open windows or tabs.
    • driver.switchTo().window(windowHandle) - Switch to specific window or tab identified by its handle.
    • Use driver.getWindowHandle() to determine currently active window or tab.

    Uploading Files

    • Use sendKeys() to provide the file path for file uploads rather than interacting with the browser's file dialog.
