Description

• Added support for launching Selenium server using Bazel JDK launcher if specified in the environment variable SELENIUM_BAZEL_SERVER_LAUNCHER.

PR Review

⏱️ Estimated effort to review [1-5]	2, because the changes are moderate in size and scope, involving environment variable checks and command construction adjustments. The logic is straightforward, but careful attention is needed to ensure the new environment configurations are handled correctly.
🧪 Relevant tests	No
🔍 Possible issues	Possible Bug: The use of ENV.fetch('SELENIUM_BAZEL_SERVER_LAUNCHER', '') in rb/spec/integration/selenium/webdriver/spec_support/test_environment.rb might lead to unexpected behavior if the environment variable is not set, as it defaults to an empty string which is then attempted to be split. This should be handled more gracefully.
🔒 Security concerns	No

PR Code Suggestions

Category	Suggestions
Best practice	Improve code safety by avoiding in-place modification of shared arrays. To avoid potential issues with mutable state, create a new array for server_command instead of modifying properties in-place. This ensures that the original properties array remains unchanged, which can prevent side effects if it's used elsewhere in the code. rb/lib/selenium/server.rb [245] -server_command = [ENV['SELENIUM_BAZEL_SERVER_LAUNCHER']] + properties + args + @additional_args +server_command = [ENV['SELENIUM_BAZEL_SERVER_LAUNCHER']] + properties.dup + args + @additional_args
Bug	Prevent duplication of command line arguments in the server command. Ensure that the @additional_args are not duplicated in the server_command when constructing the command for the Selenium server. This can be achieved by removing @additional_args from the concatenation since it's already included in properties. rb/lib/selenium/server.rb [247] -server_command = ['java'] + properties + ['-jar', @jar] + args + @additional_args +server_command = ['java'] + properties + ['-jar', @jar] + args
	Correct the formatting of the path in the environment variable to avoid potential path resolution issues. Ensure that the path specified in SELENIUM_BAZEL_SERVER_LAUNCHER is correctly formatted without unnecessary single quotes, which might be interpreted literally in some contexts, leading to path resolution issues. rb/spec/tests.bzl [179] -"SELENIUM_BAZEL_SERVER_LAUNCHER": "'$(rootpaths //java/src/org/openqa/selenium/grid:selenium_server)'", +"SELENIUM_BAZEL_SERVER_LAUNCHER": "$(rootpaths //java/src/org/openqa/selenium/grid:selenium_server)",
Maintainability	Use a local variable instead of modifying an environment variable in-place. Instead of modifying the SELENIUM_BAZEL_SERVER_LAUNCHER environment variable in-place, consider using a local variable to hold the modified value. This prevents unintended side effects across different parts of the application that might rely on the original environment variable. rb/spec/integration/selenium/webdriver/spec_support/test_environment.rb [39] -ENV['SELENIUM_BAZEL_SERVER_LAUNCHER'] = ENV.fetch('SELENIUM_BAZEL_SERVER_LAUNCHER', '').split(' ').first +selenium_bazel_server_launcher = ENV.fetch('SELENIUM_BAZEL_SERVER_LAUNCHER', '').split(' ').first
Possible issue	Add a check to ensure the JAR file path is provided when not using Bazel. To ensure that the server command is correctly constructed regardless of the environment, add a check to ensure that @jar is not nil or empty when not using Bazel to launch the server. This prevents runtime errors when attempting to launch the server without a specified JAR file. rb/lib/selenium/server.rb [247] +raise 'JAR path must be provided' if @jar.nil? || @jar.empty? server_command = ['java'] + properties + ['-jar', @jar] + args + @additional_args

✨ CI feedback usage guide:

---

The CI feedback tool (/checks) automatically triggers when a PR has a failed check.
The tool analyzes the failed checks and provides several feedbacks:

• Failed stage
• Failed test name
• Failure summary
• Relevant error logs

In addition to being automatically triggered, the tool can also be invoked manually by commenting on a PR:

/checks "https://github.com/{repo_name}/actions/runs/{run_number}/job/{job_number}"

where {repo_name} is the name of the repository, {run_number} is the run number of the failed check, and {job_number} is the job number of the failed check.

Configuration options

• enable_auto_checks_feedback - if set to true, the tool will automatically provide feedback when a check is failed. Default is true.
• excluded_checks_list - a list of checks to exclude from the feedback, for example: ["check1", "check2"]. Default is an empty list.
• enable_help_text - if set to true, the tool will provide a help message with the feedback. Default is true.
• persistent_comment - if set to true, the tool will overwrite a previous checks comment with the new feedback. Default is true.
• final_update_message - if persistent_comment is true and updating a previous checks message, the tool will also create a new message: "Persistent checks updated to latest commit". Default is true.

See more information about the checks tool in the docs.
