Website login Issue in Selenium ChromeDriver

Question

I am login to a website using Selenium and ChromeDriver. But website login details are shown as incorrect every time. But I have manually logged into the site using Chrome browser easily.

How do I login to the website using Selenium and ChromeDriver without issue?

Code:

IWebDriver driver = new ChromeDriver(service, options);
driver.Navigate().GoToUrl("https://www.textnow.com/login");
driver.FindElement(By.Name("username")).SendKeys("pankajsingh42@gmail.com");
driver.FindElement(By.Name("password")).SendKeys("*********");
driver.FindElement(By.Id("btn-login")).Click();

Answer 1

The code looks like it could work, but maybe the page loads slow and you are trying to interact with an element that does not exist yet. Be sure you wait for the first element to be ready. I added a wait to your example.

IWebDriver driver = new ChromeDriver(service, options);
driver.Navigate().GoToUrl("https://www.textnow.com/login");

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(5));
var username = wait.Until(f => f.FindElement(By.Name("username")));

username.SendKeys("pankajsingh42@gmail.com");
driver.FindElement(By.Name("password")).SendKeys("*********");
driver.FindElement(By.Id("btn-login")).Click();

Like Niels said above, it could be the timing issue. You might wanna wait until the element exists in the page and then do the stuff. Like you can make a function called WaitUntilElementIsVisible, and call that function before you find any element in the page. Will be easier for you
