How Automating Web Browsers with Selenium and C# in VS Code Using Cursor AI Assistant

Automation is transforming the software development process—making testing faster, reducing repetitive tasks, and improving productivity. In this guide, we’ll explore how to automate web browsers using Selenium with C# inside Visual Studio Code, and more specifically, how to boost your workflow using the Cursor AI assistant (v1.1.5).

🧠 Cursor is an AI-powered coding assistant embedded directly into VS Code. It helps write, explain, and debug code faster using natural language prompts.

🔧 Prerequisites

Before diving in, make sure the following tools are installed:

• .NET SDK (6.0 or later) – Download
• Visual Studio Code (v1.96.2 or later) – Download
• Cursor AI extension (v1.1.5) – Installed from https://www.cursor.so/
• Google Chrome and ChromeDriver
• NuGet packages for Selenium

🚀 Step 1: Create a New C# Project with Cursor

Open VS Code with Cursor enabled and type:

dotnet new console -n SeleniumAutomation
cd SeleniumAutomation

Ask Cursor:
💬 “Add Selenium dependencies to this C# project using NuGet.”

It will auto-generate the correct command:

💻 Step 2: Automate a Browser Using Selenium

Open Program.cs, and type this prompt into Cursor:

💬 “Create a sample Selenium script in C# that opens Chrome, searches on Google, and closes the browser.”

Cursor will generate code similar to this:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;
using System.Threading;

class Program
{
    static void Main()
    {
        using var driver = new ChromeDriver();
        driver.Navigate().GoToUrl("https://www.google.com");

        var searchBox = driver.FindElement(By.Name("q"));
        searchBox.SendKeys("Selenium with C#");
        searchBox.SendKeys(Keys.Enter);

        Thread.Sleep(3000);
        driver.Quit();
    }
}

🧠 Step 3: Debug & Explain with Cursor

Highlight any part of your code and ask:

💬 “Explain this line.”
💬 “How can I wait until the element is visible?”
💬 “Convert this to use WebDriverWait.”

Cursor will rewrite or enhance the logic with contextual explanations.

🖱 Bonus: Automating Actions via JavaScript

Want to simulate mouse interaction or click buttons? Try:

IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
js.ExecuteScript("document.querySelector('input[name=q]').click();");

You can prompt Cursor:
💬 “Use JavaScriptExecutor to click a button by CSS selector.”

You can prompt Cursor:
💬 “Use JavaScriptExecutor to click a button by CSS selector.”

🧪 Cursor for Test Automation Engineers

Cursor can also:

• Suggest NUnit test structure
• Generate test classes from comments
• Refactor repeated Selenium actions into reusable methods
• Provide answers from docs directly in VS Code
