Pressing "F12" key directly through Selenium

Question

Below is my scenario :

1. Open the URL (http://google.com)
   
2. Press "F12" key

I have tried below lines of code :

public static void main(String[] args) throws InterruptedException {

    WebDriver driver=new FirefoxDriver();
    driver.manage().window().maximize();
    driver.get("http://google.com");

    String CurrentURL= driver.getCurrentUrl();
    System.out.println("Current URL is : " + CurrentURL);

    Actions action = new Actions(driver);
    action.sendKeys(Keys.F12);

    System.out.println("successfuly pressed key F12");
    driver.close();
}

It is printing "successfuly pressed key F12" on the console. But, I don't see 'F12' being pressed on website.

Please can anyone help me out of this ?

Thanks in advance.

I have been trying to use C# selenium to automatically open browsers with the devtools console open. To date (January 2020) My experience with C# is Chrome options.AddArguments("--auto-open-devtools-for-tabs"); Firefox options.AddArgument("-devtools"); IE11 no command line options but you can use driver.FindElement(By.Id("body")).SendKeys(Keys.F12); after the browsers is open Edge I have not been able to find any way to do this automatically, so selecting the browser and pressing F12 will have to suffice.

Thanks to the other contributors who helped me get this far

For pressing F12: The following Selenium Java code using Robot could work both in Firefox and Chrome:

driver.get("https://www.google.com/");
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_F12);
robot.keyRelease(KeyEvent.VK_F12);

VS 2017 , Selenium v 3.12.1 ,C# , Firefox V 60.0.2 , Chrome V 66 , Nunit v3.10.1 , Gecko Driver v 20.1 , chrome driver v 2.4

I tried to search for Firefox but did not success but I do get solution for Chrome v66

Please provide profile like this:

options.AddArguments("--auto-open-devtools-for-tabs");
    

This is the chrome driver implementation:

ChromeOptions options = new ChromeOptions();
options.AddArgument("--start-maximized");
options.AddArguments("disable-infobars");
options.AddArguments("--disable-notifications");
options.AddArguments("--auto-open-devtools-for-tabs");
driver = new ChromeDriver(DrivePath, options, TimeSpan.FromSeconds(100));

Below commands are NOT working, this is issue with Geckodriver so Gecko team has to provide some solution or fix for that :

driver.FindElement(By.CssSelector("body")).SendKeys(Keys.F12);

Actions action = new Actions(driver); action.SendKeys(Keys.F12); action.Perform();

Actions action = new Actions(driver); action .KeyDown(Keys.Control).SendKeys(Keys.F12).KeyUp(Keys.Control).Perform();

Actions action = new Actions(driver); action.SendKeys(Keys.F12); action.Click();

Can you try pressing F12 on body of the website? I used below java junit code and it opened google and pressed F12.

@Test
public void Test_Google_FireFox() throws Exception {
    driver = new FirefoxDriver();
    driver.manage().window().maximize();
    baseUrl = "https://www.google.com";
    driver.get(baseUrl);
    driver.findElement(By.xpath("/html/body")).sendKeys(Keys.F12);

OR,

driver.findElement(By.cssSelector("body")).sendKeys(Keys.F12);

OR,

driver.findElement(By.tagName("body")).sendKeys(Keys.F12);

}

Answer 5

I think you forgot to add the perform method. So it should be:

Actions action = new Actions(driver);
action.sendKeys(Keys.F12);
action.perform();

or

Actions action = new Actions(driver);
action.sendKeys(Keys.F12).perform();
