sendKeys() not working in Selenium Webdriver
Last Updated :
28 Aug, 2024
In the world of Selenium WebDriver automation, the sendKeys() method is commonly used to input text into web elements like text fields and search boxes. However, there are times when sendKeys() might not work as expected, leading to challenges in test automation. This issue can arise due to various reasons such as element visibility, focus issues, or JavaScript interference. Understanding these issues and exploring alternative methods, such as using JavaScript Executor, is crucial for effective test automation and ensuring that your tests run smoothly.
This article will delve into why sendKeys() might fail and how you can address these issues.
Understanding sendKeys()
The sendKeys() method is used in Selenium to input text into web elements. It simulates keyboard input, allowing you to interact with text fields, password fields, and text areas on a webpage. The basic syntax is:
Java
WebElement element = driver.findElement(By.id("elementId"));
element.sendKeys("text to input");
Common Issues with sendKeys()
1. Element Not Interactable
- Issue: If an element is not interactable, sendKeys() will fail. This might occur if the element is not yet visible or enabled.
- Solution: Ensure the element is visible and enabled before attempting to send keys.
Java
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("elementId")));
element.sendKeys("text to input");
2. Element Not Found
- Issue: If the element is not found, sendKeys() will not work.
- Solution: Verify the locator used to find the element. Use reliable locators and ensure they are correct.
Java
WebElement element = driver.findElement(By.id("elementId"));
element.sendKeys("text to input");
3. Element is Covered by Another Element
- Issue: If the element is covered by another element, sendKeys() will fail because the underlying element is not clickable.
- Solution: Ensure no other element is overlapping the target element. You may need to scroll or adjust the page layout.
Java
WebElement element = driver.findElement(By.id("elementId"));
((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", element);
element.sendKeys("text to input");
- Issue: Some inputs are managed by JavaScript and may not respond to sendKeys().
- Solution: Use JavaScript to set the value of such elements.
Java
WebElement element = driver.findElement(By.id("elementId"));
((JavascriptExecutor) driver).executeScript("arguments[0].value='text to input';", element);
5. Stale Element Reference
- Issue: If the page is refreshed or the element is updated, a stale element reference exception may occur.
- Solution: Re-locate the element if it becomes stale.
Java
WebElement element = driver.findElement(By.id("elementId"));
((JavascriptExecutor) driver).executeScript("arguments[0].value='text to input';", element);
6. Solutions and Workarounds
- Wait for Element to be Visible
- Using WebDriverWait to ensure the element is interactable can prevent many issues.
Java
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("elementId")));
element.sendKeys("text to input");
- Use Actions Class for Complex Interactions
- The Actions class can be used for more complex interactions that might involve multiple steps.
Java
Actions actions = new Actions(driver);
WebElement element = driver.findElement(By.id("elementId"));
actions.moveToElement(element).click().sendKeys("text to input").perform();
7. Handle Overlapping Elements
If elements overlap, use JavaScript to interact with the element.
Java
WebElement element = driver.findElement(By.id("elementId"));
((JavascriptExecutor) driver).executeScript("arguments[0].click();", element);
element.sendKeys("text to input");
Use JavaScript Executor for JavaScript-Based Inputs
For JavaScript-managed inputs, set the value directly using JavaScript.
WebElement element = driver.findElement(By.id("elementId"));
((JavascriptExecutor) driver).executeScript("arguments[0].value = 'text to input';", element);
Refresh the WebElement
Re-locate the element if it becomes stale or if you encounter issues with element state.
Java
WebElement element = driver.findElement(By.id("elementId"));
element.sendKeys("text to input");
// Handle stale element
element = driver.findElement(By.id("elementId"));
element.sendKeys("text to input");
Example of solving Problem sendKeys() not working in Selenium Webdriver
Here’s a complete example demonstrating how to handle common issues with sendKeys():
Java
package com.example.tests;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import io.github.bonigarcia.wdm.WebDriverManager;
public class SendKeysExample {
public static void main(String[] args) {
WebDriverManager.chromedriver().setup();
// Initialize ChromeDriver instance
WebDriver driver = new ChromeDriver();
// Maximize the browser window
driver.manage().window().maximize();
try {
// Launch the Google homepage
driver.get("https://www.google.com/");
// Slow down to observe the page loading
Thread.sleep(2000); // Wait for 2 seconds
// Identify the search box element
WebElement searchBox = driver.findElement(By.name("q"));
// Slow down to observe the search box before entering text
Thread.sleep(2000); // Wait for 2 seconds
// Use JavaScript Executor to enter text into the search box
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("document.getElementsByName('q')[0].value= 'geeksforgeeks.org'");
// Slow down to observe the entered text
Thread.sleep(2000); // Wait for 2 seconds
// Retrieve the entered text to verify
String enteredText = searchBox.getAttribute("value");
System.out.println("Text entered: " + enteredText);
// Slow down before closing the browser
Thread.sleep(2000); // Wait for 2 seconds
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
// Close the browser
driver.quit();
}
}
}

In summary, while sendKeys() is a fundamental method in Selenium WebDriver for simulating user input, it is not always reliable in every scenario. Issues with element visibility, focus, or JavaScript interactions can cause sendKeys() to malfunction. By leveraging alternative approaches, such as using JavaScript Executor to directly set the value of input fields, you can overcome these challenges and enhance the robustness of your automated tests.
Understanding and addressing these issues ensures that your Selenium WebDriver tests remain effective and dependable, leading to more reliable automation outcomes
