Reviewer's Guide by SourceryThis PR implements automatic browser cleanup by adding shutdown hooks to both Playwright and Web infrastructure Apps. The implementation uses the AppDomain.CurrentDomain.ProcessExit event to ensure browser resources are properly disposed of when the application exits.

The method GoTo<TPage>() lacks error handling for scenarios where the page cannot be resolved or fails to open. This can lead to unhandled exceptions which may crash the application.
Recommended Solution:
Implement try-catch blocks around the page resolution and opening steps to handle potential exceptions gracefully and provide fallback or error logging mechanisms.

The DisposeBrowserService.Dispose(driver, container); call in the AddShutdownHook() method does not check if driver or container are already disposed or null. This could lead to unnecessary operations or errors during application shutdown.
Recommended Solution:
Add null checks and check if the resources are already disposed before attempting to dispose them again. This will prevent potential null reference exceptions and ensure cleaner resource management.

Initializing resources and registering shutdown hooks directly in the constructor can lead to issues with testability and separation of concerns. Consider initializing critical resources like _apiClientService in a dedicated initialization method rather than the constructor. This approach enhances modularity and makes unit testing easier by allowing more control over the initialization process.
Recommended Change:
public App() { }
public void Initialize() {
_apiClientService = GetNewApiClientService();
AddShutdownHook();

Using AppDomain.CurrentDomain.ProcessExit for cleanup tasks is potentially unreliable for applications that can be terminated abruptly, as this event might not always fire. Additionally, resolving IWebDriver directly in the shutdown hook couples the cleanup logic tightly with the service's availability, which can lead to issues if the service is unavailable at shutdown time.
Recommended Change:
Consider using a more reliable mechanism for cleanup, such as implementing IDisposable and ensuring that all consumers of the class properly call Dispose. This change would decouple the shutdown process from the global state and improve the reliability of resource cleanup.
public void Dispose() {
DisposeDriverService.Dispose(driver, ServicesCollection.Current);
base.Dispose();

Hey @2lambda123 - I've reviewed your changes - here's some feedback:
Overall Comments:
- Consider using IAsyncDisposable or a more robust cleanup mechanism instead of ProcessExit event handler, which isn't guaranteed to be called in all termination scenarios (e.g., force kill).
- The disposal pattern needs review - calling both specific disposal methods and this.Dispose() in the event handler could lead to double disposal issues if Dispose() is called explicitly elsewhere.
Here's what I looked at during the review
- 🟡 General issues: 3 issues found
- 🟢 Security: all looks good
- 🟢 Testing: all looks good
- 🟢 Complexity: all looks good
- 🟢 Documentation: all looks good

Consider extracting the shutdown hook logic into a shared base class or utility to avoid duplication

Add error logging in the ProcessExit event handler.
Tell me more
Consider adding error logging in the ProcessExit event handler. If an exception occurs during the disposal process, it would be beneficial to log it for debugging purposes. You could wrap the disposal calls in a try-catch block and log any exceptions that occur.

Resolve IWebDriver within the event handler in AddShutdownHook.
Tell me more
The current implementation of AddShutdownHook resolves the IWebDriver too early. Instead of resolving it when adding the hook, we should resolve it within the event handler to ensure we're disposing of the correct driver instance at shutdown. Consider modifying the method as follows:
private void AddShutdownHook()
{
AppDomain.CurrentDomain.ProcessExit += new EventHandler((sender, eventArgs) =>
{
var container = ServicesCollection.Current;
var driver = container.Resolve<IWebDriver>();
DisposeDriverService.Dispose(driver, container);
this.Dispose();
});
}This change will ensure that the correct IWebDriver instance is resolved and disposed of when the application is actually shutting down.

Description
In this pull request, the following changes are being made:
App.csin theBellatrix.Playwrightproject andApp.csin theBellatrix.Webproject.AddShutdownHookis added in both files to handle cleanup when the application is about to shut down.AddShutdownHookmethod subscribes to theProcessExitevent of the currentAppDomainto dispose of resources properly before the application exits.Here are the changes in the code:
using Bellatrix.Playwright.Services.Browser;.Appclass constructor, called theAddShutdownHookmethod to set up the shutdown hook.AddShutdownHookmethod which disposes of browser-related services properly before the application exits. The method resolves the necessary services and subscribes to theProcessExitevent, executing the cleanup logic.WrappedBrowser) in the Bellatrix.Playwright project or the WebDriver service (IWebDriver) in the Bellatrix.Web project.Description by Korbit AI
What change is being made?
Add a shutdown hook to automatically dispose of browser services and drivers upon application exit for the Playwright and Web App classes.
Why are these changes being made?
These changes ensure that browser instances are properly closed and resources are freed when the application terminates, preventing potential memory leaks and resource locks. The addition of a shutdown hook is a consistent and automated solution to handle cleanup in an orderly manner without relying on manual interventions.
