PR Review
| ⏱️ Estimated effort to review [1-5] |
3, because the PR involves multiple files and significant refactoring, including the introduction of new classes and methods, modifications to existing logic, and removal of deprecated code. The changes are well-structured and seem to follow good coding practices, but due to the extent of modifications across different components, a thorough review is required to ensure functionality and integration are preserved.
|
| 🧪 Relevant tests |
Yes
|
| 🔍 Possible issues |
Possible Regression: The removal of proxy setting methods from HtmlUnitDriver and delegation to ProxyConfigurationManager could potentially introduce regressions if not all use cases are covered by the new implementation. |
|
Code Duplication: The ProxyConfigurationManager class introduces methods (setHTTPProxy, setSocksProxy, etc.) that are very similar to each other and could benefit from further refactoring to reduce code duplication. |
|
Error Handling: The new proxy configuration management does not seem to include explicit error handling for invalid proxy configurations. It would be beneficial to add validation and error handling to prevent runtime issues. |
| 🔒 Security concerns |
No

PR Code Suggestions
| Category | Suggestions |
| Enhancement |
Initialize ProxyConfigurationManager in the constructor for better design.
It's recommended to initialize the ProxyConfigurationManager in the constructor of
HtmlUnitDriver or through dependency injection, rather than instantiating it directly in
the method where it's used. This approach enhances the design for better testability and
adherence to the single responsibility principle.
src/main/java/org/openqa/selenium/htmlunit/HtmlUnitDriver.java [171]
-private ProxyConfigurationManager proxyConfigurationManager=new ProxyConfigurationManager();
+// Assuming there's a constructor or an initialization block
+this.proxyConfigurationManager = new ProxyConfigurationManager();
Add exception handling for StaleElementReferenceException in shouldSwitchFocus method.
Consider handling StaleElementReferenceException in shouldSwitchFocus method to maintain
the previous behavior where exceptions were caught and handled.
src/main/java/org/openqa/selenium/htmlunit/HtmlUnitWebElement.java [258-263]
private boolean shouldSwitchFocus(HtmlUnitWebElement oldActiveElement) {
- final boolean jsEnabled = driver_.isJavascriptEnabled();
- final boolean oldActiveEqualsCurrent = oldActiveElement.equals(this);
- final boolean isOldElementBody = "body".equalsIgnoreCase(oldActiveElement.getTagName());
+ try {
+ final boolean jsEnabled = driver_.isJavascriptEnabled();
+ final boolean oldActiveEqualsCurrent = oldActiveElement.equals(this);
+ final boolean isOldElementBody = "body".equalsIgnoreCase(oldActiveElement.getTagName());
- return jsEnabled && !oldActiveEqualsCurrent && !isOldElementBody;
+ return jsEnabled && !oldActiveEqualsCurrent && !isOldElementBody;
+ } catch (final StaleElementReferenceException ex) {
+ // old element has gone, do nothing
+ return false;
+ }
}
Add a break statement to exit the loop once the alert is locked in alert method.
Consider adding a break statement inside the if condition after Thread.sleep to exit the
loop once the alert is locked, to avoid unnecessary iterations.
src/main/java/org/openqa/selenium/htmlunit/HtmlUnitTargetLocator.java [194-201]
for (int i = 0; i < ALERT_LOCK_RETRY_COUNT; i++) {
if (!alert.isLocked()) {
try {
Thread.sleep(ALERT_LOCK_RETRY_DELAY_MS);
} catch (final InterruptedException e) {
throw new RuntimeException(e);
}
+ } else {
+ break; // Exit the loop once the alert is locked
}
}
| | Best practice |
Encapsulate the logic of applying proxy settings in a method.
Instead of directly setting the proxy settings on proxyConfigurationManager in the
HtmlUnitDriver class, consider using a method that encapsulates the logic of applying
proxy settings to the WebClient. This approach adheres to encapsulation and separation of
concerns principles.
src/main/java/org/openqa/selenium/htmlunit/HtmlUnitDriver.java [264]
-proxyConfigurationManager.setProxySettings(proxy);
+// In HtmlUnitDriver class
+applyProxySettings(proxy);
+// This method then uses proxyConfigurationManager internally
Add input validation to proxy configuration methods to enhance robustness.
The ProxyConfigurationManager class should validate the input parameters for methods like
setHTTPProxy, setSocksProxy, and others to ensure they are not null or invalid, which
could lead to runtime errors. Adding input validation enhances the robustness of the code.
src/main/java/org/openqa/selenium/htmlunit/ProxyConfigurationManager.java [90-93]
public void setHTTPProxy(final String host, final int port, final List<String> noProxyHosts) {
+ if (host == null || host.trim().isEmpty()) throw new IllegalArgumentException("Host cannot be null or empty");
+ if (port < 0) throw new IllegalArgumentException("Port cannot be negative");
this.proxyConfig.setProxyHost(host);
this.proxyConfig.setProxyPort(port);
- noProxyHosts.forEach(this.proxyConfig::addHostsToProxyBypass);
+ if (noProxyHosts != null) {
+ noProxyHosts.forEach(this.proxyConfig::addHostsToProxyBypass);
+ }
}
Use a more specific exception for handling InterruptedException in alert method.
Replace the direct instantiation of RuntimeException with a more specific exception or
create a custom exception class to provide more context about the error.
src/main/java/org/openqa/selenium/htmlunit/HtmlUnitTargetLocator.java [197-199]
try {
Thread.sleep(ALERT_LOCK_RETRY_DELAY_MS);
} catch (final InterruptedException e) {
- throw new RuntimeException(e);
+ throw new AlertLockInterruptedException("Interrupted while waiting for alert lock", e);
}
+// Elsewhere in the class or package
+public class AlertLockInterruptedException extends RuntimeException {
+ public AlertLockInterruptedException(String message, Throwable cause) {
+ super(message, cause);
+ }
+}
+
| | Maintainability |
Refactor setHTTPProxy and setSocksProxy to avoid code duplication.
The setHTTPProxy and setSocksProxy methods in ProxyConfigurationManager have overlapping
functionality. Consider refactoring these methods to avoid code duplication, possibly by
extracting the common logic into a private method.
src/main/java/org/openqa/selenium/htmlunit/ProxyConfigurationManager.java [90-98]
-public void setHTTPProxy(final String host, final int port, final List<String> noProxyHosts) {
+private void configureProxy(final String host, final int port, final List<String> noProxyHosts, boolean isSocks) {
this.proxyConfig.setProxyHost(host);
this.proxyConfig.setProxyPort(port);
+ if (isSocks) {
+ this.proxyConfig.setSocksProxy(true);
+ }
noProxyHosts.forEach(this.proxyConfig::addHostsToProxyBypass);
}
-public void setSocksProxy(final String host, final int port, final List<String> noProxyHosts) {
- this.proxyConfig.setSocksProxy(true);
- setHTTPProxy(host, port, noProxyHosts);
-}
Remove commented-out code for better maintainability.
The method sendKeys in HtmlUnitKeyboard class has commented-out code that seems to be an
old implementation. It's a good practice to remove such commented-out code to keep the
codebase clean and maintainable.
src/main/java/org/openqa/selenium/htmlunit/HtmlUnitKeyboard.java [106-120]
-// private void addToKeyboard(final Keyboard keyboard, final char ch, final boolean isPress) {
-// if (HtmlUnitKeyboardMapping.isSpecialKey(ch)) {
-// final int keyCode = HtmlUnitKeyboardMapping.getKeysMapping(ch);
-// if (isPress) {
-// keyboard.press(keyCode);
-// modifiersState_.storeKeyDown(ch);
-// }
-// else {
-// keyboard.release(keyCode);
-// modifiersState_.storeKeyUp(ch);
-// }
-// }
-// else {
-// keyboard.type(ch);
-// }
-// }
+// Code block removed for clarity and maintainability.
Refactor redundant condition checks into a separate method in getAttribute.
Refactor the getAttribute method to reduce redundancy by extracting the common condition
check into a separate method.
src/main/java/org/openqa/selenium/htmlunit/HtmlUnitWebElement.java [285-290]
-final boolean isHtmlInput = element_ instanceof HtmlInput;
-final boolean isSelectableAttribute = "selected".equals(lowerName) || "checked".equals(lowerName);
-
-if (isHtmlInput && isSelectableAttribute) {
+if (isSelectableInputAttribute(lowerName)) {
HtmlInput htmlInput = (HtmlInput) element_;
return trueOrNull(htmlInput.isChecked());
}
+// Elsewhere in the class
+private boolean isSelectableInputAttribute(String attributeName) {
+ final boolean isHtmlInput = element_ instanceof HtmlInput;
+ final boolean isSelectableAttribute = "selected".equals(attributeName) || "checked".equals(attributeName);
+ return isHtmlInput && isSelectableAttribute;
+}
+
| | Possible issue |
Add null check for keyboard parameter in addToKeyboard method.
Ensure that addToKeyboard method handles the case where keyboard is null to prevent
NullPointerException.
src/main/java/org/openqa/selenium/htmlunit/KeyboardModifiersState.java [64-76]
public void addToKeyboard(final Keyboard keyboard, final char ch, final boolean isPress) {
+ if (keyboard == null) {
+ throw new IllegalArgumentException("Keyboard cannot be null");
+ }
if (HtmlUnitKeyboardMapping.isSpecialKey(ch)) {
final int keyCode = HtmlUnitKeyboardMapping.getKeysMapping(ch);
if (isPress) {
keyboard.press(keyCode);
storeKeyDown(ch);
} else {
keyboard.release(keyCode);
storeKeyUp(ch);
}
} else {
keyboard.type(ch);
}
}
