Selenium C# – Web Cam Access Test

Introduction

Automating browser-based webcam access is helpful for testing video input features in web applications. With ChromeOptions, Selenium lets you simulate webcam access using fake media streams. In this guide, I'll show you how to access a webcam test site and simulate webcam usage with Selenium in C#.

Code Implementation

Below is a C# Selenium script that opens a browser, navigates to a webcam test site, and simulates webcam access using ChromeOptions.

Example: Web Cam Access with Selenium in C#.

        [TestMethod]
        public void Selenium_Test()
        {
            Console.WriteLine("Selenium Test - Browser - Web Cam Access");

            // Configure ChromeOptions to pass fake media stream
            ChromeOptions options = new ChromeOptions();
            options.AddArgument("use-fake-device-for-media-stream");
            options.AddArgument("use-fake-ui-for-media-stream");

            // Initialize Chrome WebDriver with options
            IWebDriver driver = new ChromeDriver(options);

            // Maximize the browser window
            driver.Manage().Window.Maximize();

            // Set implicit wait time
            driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(30);

            // Open the webcam test website
            driver.Navigate().GoToUrl("https://webcamtests.com/check");

            // Wait for 10 seconds
            Thread.Sleep(10000);

            // Click the \"Test my cam\" button
            driver.FindElement(By.Id("webcam-launcher")).Click();

            // Wait for another 10 seconds
            Thread.Sleep(10000);

            // Quit the driver
            driver.Quit();            
        }
    }
}

Steps Explained

1. Setting Up Fake Media Stream

ChromeOptions is configured to simulate webcam access without a real device.

2. Navigating to Webcam Test Site

The browser opens the test website and waits for it to fully load.

3. Starting Webcam Test

Clicks the “Test my cam” button to simulate webcam activation.

4. Clean Exit

The browser session is properly closed after the test.

Expected Outcome

• Opens the webcam test website.

• Simulates webcam usage using fake media stream.

• Initiates webcam test via button click.

• Closes the browser session.

Conclusion

Simulating webcam access in Selenium using ChromeOptions is a handy way to automate video input tests. This example shows you how to access and interact with webcam features in a browser, all without needing an actual webcam device.
