Action class keyDown and keyUp Selenium Java-CodePudding

Code trials:

searchbx.sendKeys("computer");
Thread.sleep(6000);
Actions action=new Actions(driver);
action.keyDown(Keys.CONTROL).sendKeys("a").keyUp(Keys.CONTROL).build().perform();
action.keyDown(Keys.CONTROL).sendKeys("c").keyUp(Keys.CONTROL).build().perform();
Thread.sleep(6000);
searchbx.clear();
Thread.sleep(6000);
searchbx.click();
action.keyDown(Keys.CONTROL).sendKeys("v").keyUp(Keys.CONTROL).build().perform();

I am trying to run this but am getting the following error:

INFO: Detected dialect: W3C
Exception in thread "main" java.lang.IllegalArgumentException: keyDown argument must be an instanceof Keys: null
    at org.openqa.selenium.interactions.Actions.asKeys(Actions.java:219)
    at org.openqa.selenium.interactions.Actions.keyDown(Actions.java:115)
    at protrainingtech.automationtrainingcourse.Key.main(Key.java:22)

I am trying to run the above code in selenium but getting the above error.

CodePudding user response：

If you just want to simulate "CTRL a" and then CTRL "c" you can use the below code: (using searchbx webelement as an example from your question)

Code:

searchbx.sendKeys("computer");
Thread.sleep(6000);
Actions action = new Actions(driver);
//action.keyDown(Keys.CONTROL).sendKeys("a").keyUp(Keys.CONTROL).build().perform();
//action.keyDown(Keys.CONTROL).sendKeys("c").keyUp(Keys.CONTROL).build().perform();
searchbx.SendKeys(Keys.LEFT_CONTROL   "a");
searchbx.SendKeys(Keys.LEFT_CONTROL   "c"); 
Thread.sleep(6000);
searchbx.clear();
Thread.sleep(6000);
searchbx.click();
searchbx.sendKeys(Keys.LEFT_CONTROL   "v");

You can interchangeably use CONTROL also in this case.

CodePudding user response：

You need to add the following import:

import org.openqa.selenium.Keys;

However, as per the Key down documentation you can use the following code block:

Actions actionProvider = new Actions(driver);
Action keydown = actionProvider.keyDown(Keys.CONTROL).sendKeys("a").build();
keydown.perform();
