Selenium Java - Simulate Microphone Access using Chrome Options

Introduction

In this blog, we'll dive into how to set up ChromeOptions in Selenium WebDriver with Java to simulate microphone access during automated testing. This approach is especially handy for testing web apps that rely on microphone input, like voice recording or voice recognition features.

Simulating Microphone Access using Chrome Options

Below is a complete Selenium code example that demonstrates how to configure ChromeOptions to simulate microphone access by using fake media streams.

java

package sa.Demo.SeleniumPractice;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.testng.annotations.Test;

public class Selenium_081 {
    /****
     *  Sample Code Definition :- Selenium - Mic Access
     *  Developed  By :- Pankaj Kumar

     */
    @Test
    public void Selenium_081() throws InterruptedException {
        System.out.println("Selenium - Mic Access");

        // Configure ChromeOptions to pass fake media stream
        ChromeOptions options = new ChromeOptions();
        options.addArguments("use-fake-device-for-media-stream");
        options.addArguments("use-fake-ui-for-media-stream");
        WebDriver driver = new ChromeDriver(options);
        // Maximize the Browser Window
        driver.manage().window().maximize();
        // Open URL
        driver.get("https://www.vidyard.com/mic-test/");
        // Mic Test
        driver.findElement(By.xpath("//button[normalize-space()='Start mic Test']")).click();
        Thread.sleep(10000);
        // Quit the Driver
        driver.quit();
    }
}

Explanation

• ChromeOptions Configuration:

  • The argument use-fake-device-for-media-stream simulates a fake media stream (microphone).

  • The argument use-fake-ui-for-media-stream bypasses any UI prompt for microphone access, ensuring automation without interruptions.

• Browser Initialization: A WebDriver instance is created with the configured ChromeOptions.

• Mic Test:

  • Opens the microphone test page.

  • Automates the process of starting the microphone test by clicking the "Start mic Test" button.

• Thread.sleep(): Includes a delay to allow observation of microphone test actions (optional for live execution).

• Driver Cleanup: Ensures the WebDriver session is properly closed by quitting the driver.

Conclusion

Using ChromeOptions in Selenium WebDriver to simulate microphone access is a great way to test voice features in web apps. It removes the hassle of needing real media devices during testing, making everything smooth and efficient.
