[rb] implement navigation commands with BiDi

[titusfortner]

User description

Description

• creates context manager class, constructed with bridge instance
• pulls page load strategy from capabilities and uses in required methods
• we eventually want to figure out how to store current browsing context as state on the bridge (I think)? For now this always gets the current window handle first
• deprecates BrowsingContext

Considerations

• navigate and reload return NavigateResult objects; should I return it as a Struct or just ignore it since we aren't doing anything with it and not promising a return value?
• Should these BiDi classes be marked private api?
• I want to implement this as BrowsingContext instead of creating a new class and deprecating that one; do we need to be backwards compatible with this since we didn't mark it private api?

Motivation and Context

Ruby implementation of #13995

PR Review 🔍

⏱️ Estimated effort to review [1-5]	3, because the PR introduces a new class `ContextManager` and deprecates an existing one, `BrowsingContext`. It also modifies navigation methods in `BiDiBridge` and adds integration tests. The changes are moderate in size and involve understanding the new navigation logic and its integration with the existing system.
🧪 Relevant tests	Yes
⚡ Possible issues	Possible Bug: The `navigate`, `traverse_history`, and `reload` methods in `ContextManager` assume that `@bridge.window_handle` will always provide a valid context ID. This might not be the case if the window has been closed or not initialized properly.
	Deprecation Concern: The deprecation of `BrowsingContext` needs a clear migration path and thorough documentation to ensure that existing users can transition smoothly without breaking their implementations.
🔒 Security concerns	No

PR Code Suggestions ✨

Category	Suggestion	Score
Possible issue	Add a default value for @readiness to handle cases where page_load_strategy is not present ___ **The @readiness instance variable is being set based on the page_load_strategy from bridge.capabilities. It would be prudent to handle cases where page_load_strategy might not be present in the capabilities, to avoid potential nil errors.** [rb/lib/selenium/webdriver/bidi/context_manager.rb [36-37]](https://github.com/SeleniumHQ/selenium/pull/14094/files#diff-d33b3544b8c2f2fd2da4cae84f30b2bf830dbfb91708995b4fab8f8d6a573ea4R36-R37) ```diff page_load_strategy = bridge.capabilities[:page_load_strategy] -@readiness = READINESS_STATE[page_load_strategy] +@readiness = READINESS_STATE.fetch(page_load_strategy, 'complete') ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 8 Why: This suggestion correctly identifies a potential issue where `page_load_strategy` might be missing, which could lead to a `nil` error. Adding a default value is a crucial improvement for robustness.	8
Validation	Add URL validation to the navigate method to ensure the provided URL is valid ___ **The navigate method sends a command to navigate to a URL. It would be beneficial to validate the url parameter to ensure it is a valid URL before sending the command, to prevent potential errors.** [rb/lib/selenium/webdriver/bidi/context_manager.rb [40-43]](https://github.com/SeleniumHQ/selenium/pull/14094/files#diff-d33b3544b8c2f2fd2da4cae84f30b2bf830dbfb91708995b4fab8f8d6a573ea4R40-R43) ```diff +require 'uri' + def navigate(url, context_id: nil) + raise ArgumentError, 'Invalid URL' unless url =~ URI::DEFAULT_PARSER.make_regexp + context_id ||= @bridge.window_handle @bidi.send_cmd('browsingContext.navigate', context: context_id, url: url, wait: @readiness) end ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 7 Why: Validating the URL before navigating helps prevent errors from invalid URLs, which is a good practice for robustness, though not as critical as handling potential `nil` errors.	7
Thread safety	Use a mutex to ensure thread safety when initializing @context_manager ___ **The context_manager method initializes a new ContextManager instance if it doesn't already exist. To ensure thread safety, consider using a mutex to avoid potential race conditions when initializing @context_manager.** [rb/lib/selenium/webdriver/remote/bidi_bridge.rb [60-62]](https://github.com/SeleniumHQ/selenium/pull/14094/files#diff-812b66f6ce3688d462c12e405e4808ffc075e0b6b2b9804b236ca977539a46e7R60-R62) ```diff def context_manager - @context_manager ||= WebDriver::BiDi::ContextManager.new(self) + @context_manager_mutex ||= Mutex.new + @context_manager_mutex.synchronize do + @context_manager ||= WebDriver::BiDi::ContextManager.new(self) + end end ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 7 Why: Ensuring thread safety with a mutex is a good practice, especially in a multi-threaded environment, to avoid race conditions during the initialization of shared resources.	7
Testing	Add assertions to verify the navigate, back, and forward methods are called the expected number of times ___ **The navigation tests could benefit from adding assertions to verify that the navigate, back, forward, and refresh methods are called the expected number of times, ensuring the methods are invoked correctly.** [rb/spec/integration/selenium/webdriver/navigation_spec.rb [30-46]](https://github.com/SeleniumHQ/selenium/pull/14094/files#diff-254580087740f237f15e45221c3b7adb90c6fafeca31bedc75c0b977722138ccR30-R46) ```diff +expect(driver.navigate).to receive(:to).with(form_url).once driver.navigate.to form_url expect(driver.title).to eq(form_title) driver.find_element(id: 'imageButton').click wait.until { driver.title != form_title } expect(driver.current_url).to include(result_url) expect(driver.title).to eq(result_title) +expect(driver.navigate).to receive(:back).once driver.navigate.back expect(driver.current_url).to include(form_url) expect(driver.title).to eq(form_title) +expect(driver.navigate).to receive(:forward).once driver.navigate.forward expect(driver.current_url).to include(result_url) expect(driver.title).to eq(result_title) ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 6 Why: Adding assertions for method calls enhances the test's ability to verify correct behavior, although it's more about refining tests than fixing a critical issue.	6

**Failure summary:** The action failed because the process completed with exit code 1. This indicates that there was an error during the execution of the tests or commands. The log shows a deprecation warning related to DidYouMean::SPELL_CHECKERS.merge! which should be replaced with DidYouMean.correct_error. The error seems to occur after a code block involving describe BrowsingContext and reset_driver!.

✨ 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](https://pr-agent-docs.codium.ai/tools/ci_feedback/).
