...75 * <ul>76 * <li>if you want to apply the same behavior modification to all methods of77 * a WebDriver instance and its derived objects you can subclass78 * 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 Decorated<WebDriver> decorated;172 public final WebDriver decorate(WebDriver original) {173 Require.nonNull("WebDriver", original);174 decorated = createDecorated(original);175 return createProxy(decorated);176 }177 public Decorated<WebDriver> getDecoratedDriver() {178 return decorated;179 }180 public Decorated<WebDriver> createDecorated(WebDriver driver) {181 return new DefaultDecorated<>(driver, this);182 }183 public Decorated<WebElement> createDecorated(WebElement original) {184 return new DefaultDecorated<>(original, this);185 }186 public Decorated<WebDriver.TargetLocator> createDecorated(WebDriver.TargetLocator original) {187 return new DefaultDecorated<>(original, this);188 }189 public Decorated<WebDriver.Navigation> createDecorated(WebDriver.Navigation original) {190 return new DefaultDecorated<>(original, this);191 }192 public Decorated<WebDriver.Options> createDecorated(WebDriver.Options original) {193 return new DefaultDecorated<>(original, this);194 }195 public Decorated<WebDriver.Timeouts> createDecorated(WebDriver.Timeouts original) {196 return new DefaultDecorated<>(original, this);197 }198 public Decorated<WebDriver.Window> createDecorated(WebDriver.Window original) {199 return new DefaultDecorated<>(original, this);200 }201 public Decorated<Alert> createDecorated(Alert original) {202 return new DefaultDecorated<>(original, this);203 }204 public Decorated<VirtualAuthenticator> createDecorated(VirtualAuthenticator original) {205 return new DefaultDecorated<>(original, this);206 }207 public void beforeCall(Decorated<?> target, Method method, Object[] args) {}208 public Object call(Decorated<?> target, Method method, Object[] args) throws Throwable {209 return decorateResult(method.invoke(target.getOriginal(), args));210 }211 public void afterCall(Decorated<?> target, Method method, Object[] args, Object res) {}212 public Object onError(Decorated<?> target, Method method, Object[] args,213 InvocationTargetException e) throws Throwable214 {215 throw e.getTargetException();216 }217 private Object decorateResult(Object toDecorate) {218 if (toDecorate instanceof WebDriver) {219 return createProxy(getDecoratedDriver());220 }221 if (toDecorate instanceof WebElement) {222 return createProxy(createDecorated((WebElement) toDecorate));223 }224 if (toDecorate instanceof Alert) {225 return createProxy(createDecorated((Alert) toDecorate));226 }227 if (toDecorate instanceof VirtualAuthenticator) {228 return createProxy(createDecorated((VirtualAuthenticator) toDecorate));229 }230 if (toDecorate instanceof WebDriver.Navigation) {231 return createProxy(createDecorated((WebDriver.Navigation) toDecorate));232 }233 if (toDecorate instanceof WebDriver.Options) {234 return createProxy(createDecorated((WebDriver.Options) toDecorate));235 }236 if (toDecorate instanceof WebDriver.TargetLocator) {237 return createProxy(createDecorated((WebDriver.TargetLocator) toDecorate));238 }239 if (toDecorate instanceof WebDriver.Timeouts) {240 return createProxy(createDecorated((WebDriver.Timeouts) toDecorate));241 }242 if (toDecorate instanceof WebDriver.Window) {243 return createProxy(createDecorated((WebDriver.Window) toDecorate));244 }245 if (toDecorate instanceof List) {246 return ((List<?>) toDecorate).stream()247 .map(this::decorateResult)248 .collect(Collectors.toList());249 }250 return toDecorate;251 }252 protected final <Z> Z createProxy(final Decorated<Z> decorated) {253 Set<Class<?>> decoratedInterfaces = extractInterfaces(decorated);254 Set<Class<?>> originalInterfaces = extractInterfaces(decorated.getOriginal());255 final InvocationHandler handler = (proxy, method, args) -> {256 try {257 if (method.getDeclaringClass().equals(Object.class)258 || decoratedInterfaces.contains(method.getDeclaringClass())) {259 return method.invoke(decorated, args);260 }261 if (originalInterfaces.contains(method.getDeclaringClass())) {262 decorated.beforeCall(method, args);263 Object result = decorated.call(method, args);264 decorated.afterCall(method, result, args);265 return result;266 }267 return method.invoke(decorated.getOriginal(), args);268 } catch (InvocationTargetException e) {269 return decorated.onError(method, e, args);270 }271 };272 Set<Class<?>> allInterfaces = new HashSet<>();273 allInterfaces.addAll(decoratedInterfaces);274 allInterfaces.addAll(originalInterfaces);275 Class<?>[] allInterfacesArray = allInterfaces.toArray(new Class<?>[0]);276 return (Z) Proxy.newProxyInstance(...
