...78 * WebDriverDecorator and override some of the following methods:79 * {@link #beforeCall(Decorated, Method, Object[])},80 * {@link #afterCall(Decorated, Method, Object[], Object)},81 * {@link #call(Decorated, Method, Object[])} and82 * {@link #onError(Decorated, Method, Object[], InvocationTargetException)}</li>83 * <li>if you want to modify behavior of a specific class instances only84 * (e.g. behaviour of WebElement instances) you can override one of the85 * overloaded <code>createDecorated</code> methods to create a non-trivial86 * decorator for the specific class only.</li>87 * </ul>88 * Let's consider both approaches by examples.89 * <p>90 * One of the most widely used decorator examples is a logging decorator.91 * In this case we want to add the same piece of logging code before and after92 * each invoked method:93 * <code>94 * public class LoggingDecorator extends WebDriverDecorator {95 * final Logger logger = LoggerFactory.getLogger(Thread.currentThread().getName());96 *97 * @Override98 * public void beforeCall(Decorated<?> target, Method method, Object[] args) {99 * logger.debug("before {}.{}({})", target, method, args);100 * }101 * @Override102 * public void afterCall(Decorated<?> target, Method method, Object[] args, Object res) {103 * logger.debug("after {}.{}({}) => {}", target, method, args, res);104 * }105 * }106 * </code>107 * For the second example let's implement a decorator that implicitly waits108 * for an element to be visible before any click or sendKeys method call.109 * <code>110 * public class ImplicitlyWaitingDecorator extends WebDriverDecorator {111 * private WebDriverWait wait;112 *113 * @Override114 * public Decorated<WebDriver> createDecorated(WebDriver driver) {115 * wait = new WebDriverWait(driver, Duration.ofSeconds(10));116 * return super.createDecorated(driver);117 * }118 * @Override119 * public Decorated<WebElement> createDecorated(WebElement original) {120 * return new DefaultDecorated<>(original, this) {121 * @Override122 * public void beforeCall(Method method, Object[] args) {123 * String methodName = method.getName();124 * if ("click".equals(methodName) || "sendKeys".equals(methodName)) {125 * wait.until(d -> getOriginal().isDisplayed());126 * }127 * }128 * };129 * }130 * }131 * </code>132 * This class is not a pure decorator, it allows to not only add new behavior133 * but also replace "normal" behavior of a WebDriver or derived objects.134 * <p>135 * Let's suppose you want to use JavaScript-powered clicks instead of normal136 * ones (yes, this allows to interact with invisible elements, it's a bad137 * practice in general but sometimes it's inevitable). This behavior change138 * can be achieved with the following "decorator":139 * <code>140 * public class JavaScriptPoweredDecorator extends WebDriverDecorator {141 * @Override142 * public Decorated<WebElement> createDecorated(WebElement original) {143 * return new DefaultDecorated<>(original, this) {144 * @Override145 * public Object call(Method method, Object[] args) throws Throwable {146 * String methodName = method.getName();147 * if ("click".equals(methodName)) {148 * JavascriptExecutor executor = (JavascriptExecutor) getDecoratedDriver().getOriginal();149 * executor.executeScript("arguments[0].click()", getOriginal());150 * return null;151 * } else {152 * return super.call(method, args);153 * }154 * }155 * };156 * }157 * }158 * </code>159 * It is possible to apply multiple decorators to compose behaviors added160 * by each of them. For example, if you want to log method calls and161 * implicitly wait for elements visibility you can use two decorators:162 * <code>163 * WebDriver original = new FirefoxDriver();164 * WebDriver decorated =165 * new ImplicitlyWaitingDecorator().decorate(166 * new LoggingDecorator().decorate(original));167 * </code>168 */169@Beta170public class WebDriverDecorator {171 private

  4. Selenium 4 Is Now W3C Compliant: JSON Wireframe protocol is retiring from Selenium 4, and they are adopting W3C protocol to learn in detail about the advantages and impact of these changes.

  5. How To Use Selenium 4 Relative Locator? : Selenium 4 came with new features such as Relative Locators that allow constructing locators with reference and easily located constructors nearby. Get to know its different use cases with examples.

  6. Selenium Grid 4 Tutorial For Distributed Testing: Selenium Grid 4 allows you to perform tests over different browsers, OS, and device combinations. It also enables parallel execution browser testing, reads up on various features of Selenium Grid 4 and how to download it, and runs a test on Selenium Grid 4 with best practices.

  7. Selenium Video Tutorials: Binge on video tutorials on Selenium by industry experts to get step-by-step direction from automating basic to complex test scenarios with Selenium.
