PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis ✅ 15585 - PR Code Verified Compliant requirements: Implement WebDriver BiDi commands for installing and uninstalling web extensions Implement the following BiDi commands: webExtension.install webExtension.uninstall Requires further human verification: Support Chrome and Firefox implementations (PR mentions it will fail on stable Firefox and needs Firefox version 138)

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 PR contains tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Variable Naming Inconsistency The test class uses inconsistent variable naming conventions. In some methods the WebExtension variable is capitalized (Extension) while in others it's lowercase (extension). WebExtension Extension = new WebExtension(driver); var ex = Assertion Style The tests use direct assert statements instead of more descriptive assertion libraries that would provide better failure messages. assert exIn.get("extension").equals(extensionData.get("id"));

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Learned best practice	Add parameter null check Add a null check for the path parameter in the constructor to prevent NullPointerException. Use the Require utility class that's already being used elsewhere in the codebase to validate the input parameter. java/src/org/openqa/selenium/bidi/webextension/ExtensionArchivePath.java [25-27] public ExtensionArchivePath(String path) { - this.path = path; + this.path = org.openqa.selenium.internal.Require.nonNull("path", path); } Apply / Chat Suggestion importance[1-10]: 6 __ Why: Relevant best practice - Add null checks for parameters and properties before using them to prevent NullReferenceExceptions.	Low
General	Fix variable naming convention Variable naming convention is inconsistent. The variable Extension starts with an uppercase letter, which violates Java naming conventions. Use camelCase for variable names to maintain consistency with the rest of the codebase. java/test/org/openqa/selenium/bidi/webextension/WebExtensionTest.java [53-57] -WebExtension Extension = new WebExtension(driver); +WebExtension extension = new WebExtension(driver); var ex = - Extension.install( + extension.install( new InstallExtensionParameters(new ExtensionArchivePath(path.toString()))); assert ex.get("extension").equals(extensionData.get("id")); Apply / Chat Suggestion importance[1-10]: 5 __ Why: The suggestion correctly identifies and fixes a violation of Java variable naming conventions, improving code readability and maintainability, but it does not affect functionality or correctness.
