🔒 No security concerns identified

⚡ Key issues to review Commented Code There is a commented out line of code that might be important for the test. It should be either removed or uncommented and explained. Nightly Version The PR is using a nightly version of Selenium.WebDriver (4.25.0-nightly202409100009). This might lead to instability and should be changed to a stable version before merging.

PR Code Suggestions ✨

Category	Suggestion	Score
Possible issue	Uncomment the line to handle the user prompt in the test Uncomment the line to handle the user prompt. This will allow the test to properly close the prompt and complete the event. examples/dotnet/SeleniumDocs/BiDi/BrowsingContext/BrowsingContextTest.UserPromptEvent.cs [48] -//await browsingContext.HandleUserPromptAsync(); +await browsingContext.HandleUserPromptAsync(); Apply this suggestion Suggestion importance[1-10]: 9 Why: Uncommenting the line to handle the user prompt is crucial for the test to function correctly, as it ensures the prompt is properly closed and the event can complete. This addresses a potential issue in the test logic.	9
Enhancement	Add a timeout to the HandleUserPromptAsync method call Consider adding a timeout parameter to the HandleUserPromptAsync method call to prevent indefinite waiting in case of issues. examples/dotnet/SeleniumDocs/BiDi/BrowsingContext/BrowsingContextTest.UserPromptEvent.cs [48] -//await browsingContext.HandleUserPromptAsync(); +await browsingContext.HandleUserPromptAsync(TimeSpan.FromSeconds(5)); Apply this suggestion Suggestion importance[1-10]: 8 Why: Adding a timeout to the HandleUserPromptAsync method call is a valuable enhancement that prevents indefinite waiting, improving the robustness of the test in case of unexpected issues.	8
	Add assertions to verify the content of the user prompt Consider adding assertions to verify the content of the user prompt, such as its type or message, to ensure the correct prompt is being handled. examples/dotnet/SeleniumDocs/BiDi/BrowsingContext/BrowsingContextTest.UserPromptEvent.cs [29-30] Assert.IsNotNull(userPromptOpenedEventArgs); +Assert.AreEqual("prompt", userPromptOpenedEventArgs.Type); +Assert.AreEqual("Enter your name", userPromptOpenedEventArgs.Message); Console.WriteLine(userPromptOpenedEventArgs); Apply this suggestion Suggestion importance[1-10]: 7 Why: Adding assertions to verify the content of the user prompt enhances the test by ensuring that the correct prompt is being handled, which improves test accuracy and reliability.	7
Best practice	Add error handling for the user prompt interaction Consider adding a try-catch block around the event handling to gracefully handle any exceptions that might occur during the prompt interaction. examples/dotnet/SeleniumDocs/BiDi/BrowsingContext/BrowsingContextTest.UserPromptEvent.cs [46-50] -driver.FindElement(By.Id("prompt")).Click(); +try +{ + driver.FindElement(By.Id("prompt")).Click(); -//await browsingContext.HandleUserPromptAsync(); + await browsingContext.HandleUserPromptAsync(); -var userPromptClosedEventArgs = await tcs.Task.WaitAsync(TimeSpan.FromSeconds(5)); + var userPromptClosedEventArgs = await tcs.Task.WaitAsync(TimeSpan.FromSeconds(5)); +} +catch (Exception ex) +{ + Console.WriteLine($"Error handling user prompt: {ex.Message}"); + Assert.Fail("User prompt handling failed"); +} Apply this suggestion Suggestion importance[1-10]: 8 Why: Implementing a try-catch block for error handling during user prompt interaction is a best practice that enhances the test's robustness by gracefully managing exceptions and providing informative error messages.	8

Then we can implicitly convert RemoteNodeValue (if I remember correctly) to SharedId.

await context.CaptureScreenshotAsync(new() { Clip = new ElementClipRectangle(element) });

And moving forfard:

await context.CaptureScreenshotAsync(new() { Clip = ClipRectangle.Element(element) });

Would be great if context1 can expose CreateContextAsync method, which implicitly sets ReferenceContext to the context1
