So I have the following code:
public static void main(String[] args) throws AWTException, InterruptedException {
Robot robot = new Robot();
robot.setAutoWaitForIdle(true);
robot.setAutoDelay(40);
// This works fine
robot.mouseMove(40, 130);
robot.mousePress(InputEvent.BUTTON1_MASK);
robot.delay(200);
robot.mouseRelease(InputEvent.BUTTON1_MASK);
robot.delay(200);
// The 'a' is never inputted
robot.keyPress(KeyEvent.VK_A);
robot.delay(200);
robot.keyRelease(KeyEvent.VK_A);
}
This code successfully moves the mouse to the location 40, 130 and clicks. I make sure to have a text editor open in this location so that it becomes focused.
The next bit of code is the issue. The keyPress/Release snippet works perfectly fine for other codes. (Like 100, corresponding to the number 4.) But for some reason the letter 'a' will not be printed into the text editor.
I have tried having the program continually loop and print a for ~5 seconds. After the programatic click it will not print 'a' in the text editor. If I click on the editor again myself during this time, the string of 'a's will then start to appear.
What is causing this behavior and how can I fix it?
As i assumed in my comments i think you have a problem focusing the editor correctly.
You can try to use the Windows solution by doing ALT+TAB and then release it to select the editor.
Robot robot = new Robot();
robot.setAutoWaitForIdle(true);
robot.setAutoDelay(40);
robot.keyPress(KeyEvent.VK_ALT);//on mac use VK_META
robot.keyPress(KeyEvent.VK_TAB);
robot.keyRelease(KeyEvent.VK_ALT);//on mac use VK_META
robot.keyRelease(KeyEvent.VK_TAB);
robot.keyPress(KeyEvent.VK_A);
robot.delay(200);
robot.keyRelease(KeyEvent.VK_A);

I'm trying to use Robot in order to switch apps, and then enter some text. To do this (on my mac), I'm pressing Meta, Tab, and then releasing Tab, Meta in this order:
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_META);
robot.keyPress(KeyEvent.VK_TAB);
robot.keyRelease(KeyEvent.VK_TAB);
robot.keyRelease(KeyEvent.VK_META);
This works, but only occasionally (about every 5 or six presses). I've tried calling Thread.wait() inbetween press and release, but this has no effect. Neither does trying to mask Tab with META_DOWN_MASK. I also tried using the JavaFX Robot (com.sun.glass.ui.Robot), but the JavaFX version doesn't work at all.
Ah.. Seems that I need to specify a delay between the events. Updated:
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_META);
robot.delay(300);
robot.keyPress(KeyEvent.VK_TAB);
robot.keyRelease(KeyEvent.VK_TAB);
robot.keyRelease(KeyEvent.VK_META);

Basically i've selected some text and trying to copy it; but below code is not doing Ctrl+C during runtime-nothing is storing into clipboard-however manually i've tried my keys are working fine, but it used to work few days back. Could you please help me on this issue.
robot.keyPress(KeyEvent.VK_CONTROL);
Thread.sleep(2000);
robot.keyPress(KeyEvent.VK_C);
Thread.sleep(2000);
robot.keyRelease(KeyEvent.VK_CONTROL);
Thread.sleep(2000);
robot.keyRelease(KeyEvent.VK_C);
*
First you need to release the key "C" and then "Control" key.
robot.keyPress(KeyEvent.VK_CONTROL);
Thread.sleep(2000);
robot.keyPress(KeyEvent.VK_C);
Thread.sleep(2000);
robot.keyRelease(KeyEvent.VK_C);
Thread.sleep(2000);
robot.keyRelease(KeyEvent.VK_CONTROL);
I make tests with WebDriver and at a moment a popup appears, with no fixed attribute (auto-generated).
So, the simplest way (I think) is to press the key 'Enter' on the keyboard.
But I can't find the way to say 'Just click on the browser, not on an element of the browser'.
It's possible with WebDriver? How can I achieve it?
An alternative is to use the java.awt.Robot to simulate a keyboard's interaction and not a WebElement's treatment.
[WebDriver code]
try {
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
robot.delay(200);
}
[WebDriver code]
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_ENTER); //press enter key
robot.keyRelease(KeyEvent.VK_ENTER); //release enter key
You should specify the release command also while the enter key has been pressed.
Using Actions utility we can achieve the same:
Actions builder = new Actions(driver);
builder.keyDown(Keys.RETURN).keyUp(Keys.RETURN).build().perform();
You can do something like this
driver.findElement(By.tagName("body")).sendKeys(Keys.ENTER);
What is the VK_[key] code for the command key on a mac, if one exists? I am trying to get a Robot (java Robot) to press the command key. I am using the command keyPress(), and I need to know the integer keycode for the command key on a mac.
KeyEvent.VK_META, with key code 157, is Java's virtual key that maps to the the Mac command key.
KeyEvent.VK_META can be used as COMMAND button in Mac OS.
if its not working with you, that is because you need to add a delay
sample code for opening a new tab
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_META);
robot.delay(200);
robot.keyPress(KeyEvent.VK_T);
robot.keyRelease(KeyEvent.VK_META);
robot.keyRelease(KeyEvent.VK_T);
there is also isMetaDown() method, which in my case works if somebody wants to use the shortcuts for copy/paste text and so on.
Sample code:
public void keyPressed(KeyEvent e) {
if (e.isMetaDown() && (e.getKeyCode() == KeyEvent.VK_V) && readonly.isSelected()){
e.consume();
}
}
I saw that lots of people have Problems uploading a file in a test Environment with Selenium WebDriver. I use the selenium WebDriver and java, and had the same problem. I finally have found a solution, so i will post it here hoping that it helps someone else.
When i need to upload a file in a test, i click with Webdriver in the button and wait for the window "Open" to pop. And then i copy the path to the file in the clipboard and then paste it in the "open" window and click "Enter". This is working because when the window "open" pops up, the focus is always in the "open" button.
You will need these classes and method:
import java.awt.Robot;
import java.awt.event.KeyEvent;
import java.awt.Toolkit;
import java.awt.datatransfer.StringSelection;
public static void setClipboardData(String string) {
StringSelection stringSelection = new StringSelection(string);
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(stringSelection, null);
}
And that is what i do, just after opening the "open" window:
setClipboardData("C:\\path to file\\example.jpg");
//native key strokes for CTRL, V and ENTER keys
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
And that´s it. It is working for me, i hope it works for some of you.
Actually, there is an in-built technique for this, too. It should work in all browsers and operating systems.
Selenium 2 (WebDriver) Java example:
// assuming driver is a healthy WebDriver instance
WebElement fileInput = driver.findElement(By.xpath("//input[#type='file']"));
fileInput.sendKeys("C:/path/to/file.jpg");
The idea is to directly send the absolute path to the file to an element which you would usually click at to get the modal window - that is <input type='file' /> element.
Thanks Alex,
Java Robot API helped me for uploading file. I was fedup with File Upload using WebDriver. Following is the code I used (Small modification to yours):
Robot robot = new Robot();
robot.delay(1000);
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
robot.delay(1000);
Thanks Alex! I needed this since I could not get the sendKeys function to work when used via Play framework 2.1 (fluentlenium wrapper). I am testing over Firefox [17.0.7] for Mac and had to make a few mods to get it working. Below is an approximation of the final snippet I used.
val file = new File(PATH_TO_IPA)
val stringSelection: StringSelection = new StringSelection(file.getAbsolutePath)
Toolkit.getDefaultToolkit.getSystemClipboard().setContents(stringSelection, null)
val robot: Robot = new Robot()
// Cmd + Tab is needed since it launches a Java app and the browser looses focus
robot.keyPress(KeyEvent.VK_META)
robot.keyPress(KeyEvent.VK_TAB)
robot.keyRelease(KeyEvent.VK_META)
robot.keyRelease(KeyEvent.VK_TAB)
robot.delay(500)
robot.keyPress(KeyEvent.VK_META)
robot.keyPress(KeyEvent.VK_SHIFT)
robot.keyPress(KeyEvent.VK_G)
robot.keyRelease(KeyEvent.VK_META)
robot.keyRelease(KeyEvent.VK_SHIFT)
robot.keyRelease(KeyEvent.VK_G)
robot.keyPress(KeyEvent.VK_META)
robot.keyPress(KeyEvent.VK_V)
robot.keyRelease(KeyEvent.VK_META)
robot.keyRelease(KeyEvent.VK_V)
robot.keyPress(KeyEvent.VK_ENTER)
robot.keyRelease(KeyEvent.VK_ENTER)
robot.delay(500)
robot.keyPress(KeyEvent.VK_ENTER)
robot.keyRelease(KeyEvent.VK_ENTER)
The switching of application on Mac is much better to do with AppleScript. AppleScript is integrated to system, so it will be always functional and does not depend on order of apps on Cmd+Tab. Your test/app will be less fragile.
https://developer.apple.com/library/content/documentation/AppleScript/Conceptual/AppleScriptLangGuide/reference/ASLR_cmds.html
You need only detect you are on mac and has name of the application.
Runtime runtime = Runtime.getRuntime();
String[] args = { "osascript", "-e", "tell app \"Chrome\" to activate" };
Process process = runtime.exec(args);
