Refresh is not working using sendkeys ,Selenium JAVA - selenium

Question

I am trying to automate google search,normal sendkeys is working ,but when I try to send using keys.F5 or ascii code ,refresh wont work
also when try to do location reload it gives error as " The method execute_script(String) is undefined for the type WebDriver
"
Tried instead of F5 ,F1 key also but no avail
` package com.at.sample;
import org.openqa.selenium.Keys;
import java.lang.Thread;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
// import org.openqa.selenium.Alert;
import java.util.List;
public class Refreshgoogle {
public static void main(String[] args) throws InterruptedException {
WebDriver driver;
System.setProperty("webdriver.chrome.driver","c://chromedriver.exe");
driver= new ChromeDriver();
//Launch the Application Under Test (AUT)
driver.get("http://google.com");
Actions action = new Actions(driver);
WebElement element = driver.findElement(By.name("q"));
element.sendKeys("test data");
//sends normal keybaord strokes
// approch 1 driver.findElement(By.xpath("//html")).sendKeys(Keys.F5);
// approch 2.1 WebElement element1 = driver.findElement(By.xpath("//*[#id=\"tsf\"]/div[2]/div[1]/div[2]/div[2]"));
//approch 2.2 element1.sendKeys(Keys.F1);
// approch 3 driver.findElement(By.xpath("//*[#id=\"gsr\"]")).sendKeys(Keys.F5);
// driver.execute_script("location.reload(true);");
System.out.println(driver.getTitle());
// working driver.navigate().to(driver.getCurrentUrl());
}
}
`
There are 4 approaches
First 3 wont refresh pagea
when used 4th it shows error as The method execute_script(String) is undefined for the type WebDriver

Answer 1

You can refresh in below ways:
1.Using get method and recursive way
driver.get("https://URL.com");
driver.get(driver.getCurrentURL());
Using Navigate method and Recursively calling your URL
driver.get("https://URL.com");
driver.navigate.to(driver.getCurrentURL());
Using one valid webelement and send keys
driver.get("https://URL.com");
driver. findElement(By.id("username")).sendKeys(Keys.F5);
Hope this help.

Answer 2

Please refer below solution
driver.navigate.refresh();
If you want to refresh your page using keys then you can also use Robot class.
Robot robot = new Robot(); // Robot class throws AWT Exception
Thread.sleep(2000); // Thread.sleep throws InterruptedException
robot.keyPress(KeyEvent.VK_CONTROL); // press Control key down key of
robot.keyPress(KeyEvent.VK_F5);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyRelease(KeyEvent.VK_F5);
Thread.sleep(2000);

Answer 3

WebElement(I) sendKeys() will not accept Keys (keyboard keys). This can be handled using Actions class only.
Additionally, if you need to refresh the page, use WebDriver() refresh() or get current URL using getCurrentUrl() of same interface and navigate() using same url as parameter.
Update:
Here is the detailed explanation on each approach:
1) As per 'https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/WebElement.html#sendKeys-java.lang.CharSequence...-', sendKeys() in WebElement(I) accepts only char sequence (i.e. string.).
// approch 1 driver.findElement(By.xpath("//html")) returns a WebElement and this element sendKeys will accept only char sequence. Hence, your approach r=to refresh using Keys.F5 won't work here.
2) // approch 2.1 WebElement element1 = driver.findElement(By.xpath("//*[#id=\"tsf\"]/div[2]/div[1]/div[2]/div[2]"));
//approch 2.2 element1.sendKeys(Keys.F1);
Same explanation as approach 1.
3) // approch 3 driver.findElement(By.xpath("//*[#id=\"gsr\"]")).sendKeys(Keys.F5);
Did the same kind of operation as approach 1 and is explained there.
4) If we need to use javascriptexecutor, first we need to create javascriptexecutor object like below and should call execute_script() using reference variable of that object:
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript(Script,Arguments);
If you are not created this object, you will get 'execute_script(String) is undefined for the type WebDriver', which is expected.
Hence, the 4 approaches what you tried will not refresh the page.
Instead, you can use below options:
1) Actions class sendKeys(): which will accept keyboard keys.
2) using driver.navigate().refresh();
3) Using javascriptexecutor after creating an object for the same (as explained in approach 4)
Try with this code:
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import io.github.bonigarcia.wdm.WebDriverManager;
public class TestRefresh {
public static void main(String[] args) {
WebDriverManager.chromedriver().setup();
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("https://www.google.com");
`// case 1:`
`driver.navigate().to(driver.getCurrentUrl());`
`// case 2:`
`((JavascriptExecutor)driver).executeScript("document.location.reload()");`
`// case 3:`
`driver.navigate().refresh();`
}
}
