⚡ Recommended focus areas for review Resource Cleanup The WebDriver instance should be properly disposed using a try-finally block to ensure cleanup even if tests fail WebDriver driver = new ChromeDriver(); driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500); Hard-coded Wait The implicit wait timeout is hardcoded to 500ms which may be too short for some environments. Consider making this configurable driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500);

PR Code Suggestions ✨

Latest suggestions up to 020711f
Explore these optional code suggestions:

Category	Suggestion	Score
General	Ensure proper resource cleanup Implement proper cleanup in case of test failure by wrapping the WebDriver operations in a try-finally block to ensure driver.Quit() is always called examples/dotnet/SeleniumDocs/Interactions/AlertsTest.cs [33-81] WebDriver driver = new ChromeDriver(); -driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500); -// ... test code ... -driver.Quit(); //close all windows +try { + driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500); + // ... test code ... +} +finally { + driver.Quit(); //close all windows +} Suggestion importance[1-10]: 9 Why: Adding a try-finally block is crucial for ensuring WebDriver resources are properly cleaned up even if tests fail, preventing resource leaks and orphaned browser processes.	9
	Optimize wait condition reuse Reuse the WebDriverWait instance instead of creating multiple wait conditions for each alert, as the timeout value is the same examples/dotnet/SeleniumDocs/Interactions/AlertsTest.cs [44-70] +var alertIsPresent = SeleniumExtras.WaitHelpers.ExpectedConditions.AlertIsPresent(); WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30)); -wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.AlertIsPresent()); +wait.Until(alertIsPresent); // ... more code with same wait conditions ... -wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.AlertIsPresent()); +wait.Until(alertIsPresent); Suggestion importance[1-10]: 5 Why: Reusing the AlertIsPresent condition improves code efficiency and readability by avoiding redundant object creation, though the performance impact is minimal.	5

Suggestions up to commit 020711f

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); 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"); 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"); +} 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

#2089 this is the new PR. i don't see changes on website.
2084 should be closed- used a .net library we aren't suppose to use.
