Send keys not working , right xpath and id (Selenium) - selenium

Question

Tried sendomg keys , right relative xpath or ID used but still not working properly
Tried using absolute xpath , relative xpath also ID. Tried using selassist and chropath still not working. Could there be something preventing it?
public void LoginWebSystem() {
driver = new ChromeDriver();
driver.get("http://localhost:82");
WebElement email = driver.findElement(By.id("login_username"));
email.sendKeys("superadmin");
System.out.println("Username Set");
WebElement password = driver.findElement(By.id("login_password"));
password.sendKeys("nelsoft121586");
System.out.println("Password Set");
WebElement login = driver.findElement(By.id("login_submit"));
login.click();
System.out.println("Login Button Clicked");
String newUrl = driver.getCurrentUrl();
if(newUrl.equalsIgnoreCase("http://localhost:82/controlpanel.php")){
System.out.println("Login Success");
}
else {
System.out.println("Login Failed");
}
driver.findElement(By.partialLinkText("Product")).click();
System.out.println("Successful in proceeding to Product Page");
driver.findElement(By.id("createlink")).click();
System.out.println("Successful in proceeding to Create Product by Detailed");
driver.switchTo().alert().accept();
System.out.println("Successful in clicking alert button");
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
}
#Test (priority=1)
public void ProductDetails() {
WebElement product = driver.findElement(By.xpath(" //*[#id="text-product"]"));
product.sendKeys("superadmin");
}
}
Expected output should input superadmin to product textbox

Answer 1

You have a typo in your XPath expression:
WebElement product = driver.findElement(By.xpath(" //*[#id="text-product"]"));
^ remove this space break
It's better to use By.Id locator strategy where possible as this is the fastest and the most robust way of identifying elements in DOM
Consider using Explicit Wait to ensure that the element is present and can be interacted with as it might be the case the element becomes available after document.readyState becomes complete. Check out How to use Selenium to test web applications using AJAX technology article for more detailed explanation.
new WebDriverWait(driver, 10)
.until(ExpectedConditions.elementToBeClickable(By.id("text-product")))
.click();
Make sure that your selector matches an <input> because if the id belongs to other element type like <div> it doesn't make a lot of sense to send keys there.
