PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

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

🧪 PR contains tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Resource Management The WebDriver instance should be properly disposed using a 'using' statement or try-finally block to ensure proper cleanup of resources Hard-coded Wait The implicit wait timeout is hardcoded to 500ms which may be too short for some scenarios and could lead to flaky tests

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
General	Ensure proper resource cleanup by using a disposal pattern for WebDriver instances Wrap the WebDriver instance in a using statement to ensure proper disposal of resources, even if an exception occurs. examples/dotnet/SeleniumDocs/Interactions/AlertsTest.cs [33-34] -WebDriver driver = new ChromeDriver(); -driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500); +using (WebDriver driver = new ChromeDriver()) +{ + driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500); Apply this suggestion Suggestion importance[1-10]: 8 Why: Using a 'using' statement ensures proper disposal of WebDriver resources even in case of exceptions, preventing memory leaks and resource exhaustion. This is a critical best practice for managing IDisposable objects.	8
	Simplify alert text verification by removing unnecessary intermediate variables Reuse the IAlert variable declaration to avoid redundant variable assignments and improve code readability. examples/dotnet/SeleniumDocs/Interactions/AlertsTest.cs [48-50] -IAlert alert = driver.SwitchTo().Alert(); -string text = alert.Text; -Assert.AreEqual(text, "Sample Alert"); +var alert = driver.SwitchTo().Alert(); +Assert.AreEqual(alert.Text, "Sample Alert"); Apply this suggestion Suggestion importance[1-10]: 4 Why: The suggestion improves code readability and reduces unnecessary variable assignments, though it's a minor optimization that doesn't significantly impact functionality.	4
Possible issue	Add error handling for alert interactions to improve test robustness Add try-catch block around alert interactions to handle potential NoAlertPresentException and improve test reliability. examples/dotnet/SeleniumDocs/Interactions/AlertsTest.cs [46-47] -wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.AlertIsPresent()); -IAlert alert = driver.SwitchTo().Alert(); +try { + wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.AlertIsPresent()); + IAlert alert = driver.SwitchTo().Alert(); +} catch (WebDriverTimeoutException) { + throw new Exception("Alert did not appear within timeout"); +} Apply this suggestion Suggestion importance[1-10]: 7 Why: Adding proper error handling for alert interactions makes the test more robust and provides clearer error messages when alerts fail to appear, improving test maintainability and debugging.	7

@A1exKH the tests are failing because of this -Error: D:\a\seleniumhq.github.io\seleniumhq.github.io\examples\dotnet\SeleniumDocs\Interactions\AlertsTest.cs(58,24): error CS0103: The name 'SeleniumExtras' does not exist in the current context . It is a .net package which is required for the implemented code to run. It is a problem with the environment.

The SeleniumExtras is a .net package required for ExpectedConditions
