[JAVA] Use Shift Right and Shift Left properly in Selenium

Overview in 3 lines

problem

If you want to keyDown using Selenium in Java, write the following code.

public void sendKey(WebDriver webDriver, CharSequence... keys) {
  WebElement element = webDriver.findElement(By.className("hoge"))
  element.sendKeys(keys);
}

WebElement.sendKeys takesCharSequence ...as an argument, but often uses the provided enumKeys. However, be careful if you want to use the same function keys on the left and right, such as the right Shift key / left Shift key.

The implementation of enumKeys is as follows. SHIFT / LEFT_SHIFT are defined respectively, but unfortunately the behavior of the left Shift key will behave regardless of which one is sent.

Keys.java


public enum Keys implements CharSequence {
  ...
  SHIFT        ('\uE008'),
  LEFT_SHIFT   (Keys.SHIFT),
  CONTROL      ('\uE009'),
  LEFT_CONTROL (Keys.CONTROL),
  ALT          ('\uE00A'),
  LEFT_ALT     (Keys.ALT),
  LEFT         ('\uE012'),
  ARROW_LEFT   (Keys.LEFT),
  UP           ('\uE013'),
  ARROW_UP     (Keys.UP),
  RIGHT        ('\uE014'),
  ARROW_RIGHT  (Keys.RIGHT),
  DOWN         ('\uE015'),
  ARROW_DOWN   (Keys.DOWN),
  ...
}

solution

Keys implements CharSequence, and the constructor and toString () implementation are as follows.

Keys.java


public enum Keys implements CharSequence {
  ...

  private final char keyCode;
  private final int codePoint;

  Keys(Keys key) {
    this(key.charAt(0));
  }

  Keys(char keyCode) {
    this.keyCode = keyCode;
    this.codePoint = String.valueOf(keyCode).codePoints().findFirst().getAsInt();
  }

  ...

  @Override
  public String toString {
    return String.valueOf(keyCode);
  }
}

Also, WebElement.sendKeys only combines the given keycodes with line breaks and sends them to WebDriver. Therefore, it will be recognized normally by specifying it with a character string as shown below without using the KeyCode defined in Keys.SHIFT.

  WebElement element = webDriver.findElement(By.className("hoge"))
  element.sendKeys("ShiftRight");
