I've been trying to implement headless browser to my tests and I'm getting an error message that shows me this: "Unable to locate element: {"method":"id","selector":"my_id"}". This is the code that I'm working with:
[TestFixture]
class ClientesSystemTest
{
private ChromeOptions options;
private NewClientesPage page;
private IWebDriver driver;
public ClientesSystemTest()
{
options = new ChromeOptions();
options.AddArgument("--headless");
driver = new ChromeDriver(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), options);
page = new NewClientesPage(driver);
}
[Test]
public void CadastraCliente()
{
page.Visita();
page.Cadastra("Paulo", "Guedes", "00870021087", "Rua abcdwxyz, 14", 15);
driver.Close();
}
}
and this is the Cadastra method.:
public void Cadastra(string nome, string sobrenome, string cpf, string endereco, int idade)
{
IWebElement nomeCliente = driver.FindElement(By.Id("Nome"));
IWebElement sobrenomeCliente = driver.FindElement(By.Id("Sobrenome"));
IWebElement cpfCliente = driver.FindElement(By.Id("CPF"));
IWebElement enderecoCliente = driver.FindElement(By.Id("Endereco"));
IWebElement idadeCliente = driver.FindElement(By.Id("Idade"));
IWebElement estadoCivilCliente = driver.FindElement(By.Name("EstadoCivil"));
driver.FindElement(By.CssSelector("[value=Divorciado]")).Click();
nomeCliente.SendKeys(nome);
sobrenomeCliente.SendKeys(sobrenome);
cpfCliente.SendKeys(cpf);
enderecoCliente.SendKeys(endereco);
idadeCliente.SendKeys(idade.ToString());
nomeCliente.Submit();
}
I've tried everything by this point. The test runs normally without the headless feature. Does anyone have a solution for this error? Thanks.
My guess would be that your site shows different elements depending on the browser resolution. Typically the headless browser is a smaller setting so I'd make sure it's set to the same size you use when you test non-headless.
