Selenium-webdriver is having trouble locating an element through the CSS selector

I encountered an issue while using selenium-webdriver in JavaScript to input a value into a field. Here is my test.js code:

async () => {
  let driver = await new webdriver.Builder().forBrowser("chrome").build();
  try {
    await driver.get("http://test.com");
     await driver.findElement(By.id('user')).sendKeys("test", Key.RETURN);
  }catch (e) {    
     console.log(e);
  } finally {
     await driver.quit();
  }
}

However, I received the following error message in the console:

NoSuchElementError: no such element: Unable to locate element: {"method":"css selector","selector":"*[id="user"]"}
(Session info: chrome=80.0.3987.163)

I am confused as the desired field in the HTML looks like this:

<input placeholder="User Name" type="text" id="user" class="input" value="">

Can anyone provide assistance on how to resolve this problem?

Answer №1

If you want to ensure that an element is located on the page before taking any action, you can utilize the wait function from Selenium WebDriver.

 await driver.get("http://example.com");

 // Use this line to wait for the element to be present on the page
 await driver.wait(until.elementLocated(By.id('username')));

 await driver.findElement(By.id('username')).sendKeys("sample", Key.RETURN);
