Adding WaitForDownload test for .NET

[halex2005]

User description

Hi!

Description

I've added WaitForDownload test case for .NET. Review, please.

Note, that I've also added --no-sandbox switch to ChromeOptions because chrome crashes without it. It's to make sure that tests are green.

Types of changes

• [ ] Change to the site (I have double-checked the Netlify deployment, and my changes look good)
• [x ] Code example added (and I also added the example to all translated languages)
• [ ] Improved translation
• [ ] Added new translation (and I also added a notice to each document missing translation)

Checklist

• [x ] I have read the contributing document.
• [x ] I have used hugo to render the site/docs locally and I am sure it works.

PR Reviewer Guide 🔍

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

🧪 PR contains tests

🔒 Security concerns Security concern: Adding '--no-sandbox' to ChromeOptions (examples/dotnet/SeleniumDocs/BaseTest.cs, line 42) disables the Chrome sandbox, which is a security feature. This can potentially expose the system to security risks if malicious code is executed. While it may be necessary for testing environments, it should be used with caution and not in production environments.

⚡ Key issues to review Security Concern Adding '--no-sandbox' argument to ChromeOptions may introduce security risks in production environments. Error Handling The WaitForDownload test method lacks proper error handling for potential exceptions during file operations.

PR Code Suggestions ✨

Category	Suggestion	Score
Error handling	Add error handling when deleting files to manage potential exceptions ___ **Consider using File.Delete() within a try-catch block to handle potential exceptions that may occur during file deletion, such as access denied or file not found errors.** [examples/dotnet/SeleniumDocs/BiDi/CDP/NetworkTest.cs [192]](https://github.com/SeleniumHQ/seleniumhq.github.io/pull/1885/files#diff-e31523c285a75f1ed30aba52eb3c36546df30c19cd434a14ffbf02c431da54fcR192-R192) ```diff -File.Delete(downloadedFilePath); +try +{ + File.Delete(downloadedFilePath); +} +catch (IOException ex) +{ + Console.WriteLine($"Error deleting file: {ex.Message}"); +} ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 9 Why: This suggestion significantly enhances the code by adding error handling for file deletion, which is crucial for managing exceptions like access denied or file not found, thereby improving reliability.	9
	Add exception handling to the event handler to catch and log specific errors ___ **Consider using a more specific exception type instead of Exception when catching exceptions. This helps in better error handling and provides more information about the specific error that occurred.** [examples/dotnet/SeleniumDocs/BiDi/CDP/NetworkTest.cs [173-183]](https://github.com/SeleniumHQ/seleniumhq.github.io/pull/1885/files#diff-e31523c285a75f1ed30aba52eb3c36546df30c19cd434a14ffbf02c431da54fcR173-R183) ```diff session.DevToolsEventReceived += (sender, args) => { - var downloadState = args.EventData["state"]?.ToString(); - if (args.EventName == "downloadProgress" && - (string.Equals(downloadState, "completed") || - string.Equals(downloadState, "canceled"))) + try { - downloadId = args.EventData["guid"].ToString(); - downloaded = downloadState.Equals("completed"); - downloadCompleted.Set(); + var downloadState = args.EventData["state"]?.ToString(); + if (args.EventName == "downloadProgress" && + (string.Equals(downloadState, "completed") || + string.Equals(downloadState, "canceled"))) + { + downloadId = args.EventData["guid"].ToString(); + downloaded = downloadState.Equals("completed"); + downloadCompleted.Set(); + } + } + catch (KeyNotFoundException ex) + { + Console.WriteLine($"Error accessing EventData: {ex.Message}"); } }; ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 8 Why: The suggestion correctly adds exception handling to the event handler, which enhances error management by catching specific exceptions and logging them, improving robustness and debugging capabilities.	8
Best practice	Use null-coalescing operator when combining paths to handle potential null values ___ **Consider using Path.Combine() to construct the file path instead of string concatenation. This ensures that the correct path separator is used for the current operating system.** [examples/dotnet/SeleniumDocs/BiDi/CDP/NetworkTest.cs [190]](https://github.com/SeleniumHQ/seleniumhq.github.io/pull/1885/files#diff-e31523c285a75f1ed30aba52eb3c36546df30c19cd434a14ffbf02c431da54fcR190-R190) ```diff -var downloadedFilePath = Path.Combine(downloadPath, downloadId); +var downloadedFilePath = Path.Combine(downloadPath, downloadId ?? string.Empty); ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 7 Why: The suggestion improves the code by using a null-coalescing operator to handle potential null values when combining paths, ensuring that the path construction is robust and error-free.	7
Documentation	Add a comment to explain the usage of a potentially security-impacting browser argument ___ **Consider adding a comment explaining why the "--no-sandbox" argument is being used. This argument can have security implications, so it's important to document the reason for its usage.** [examples/dotnet/SeleniumDocs/BaseTest.cs [35]](https://github.com/SeleniumHQ/seleniumhq.github.io/pull/1885/files#diff-13e7f59b8933cf7834665df17e6282b912e7b6a94eb3d3ea51e02517365c77ceR35-R35) ```diff +// Adding --no-sandbox for CI/CD environments or when running with limited privileges options.AddArgument("--no-sandbox"); ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 6 Why: Adding a comment to explain the use of "--no-sandbox" is a good practice for documentation, especially given its security implications, but it is not critical to the functionality of the code.	6
