로케이터 셀렌을 찾을 수 없습니다. 3.4

Question

매우 이상합니다. 테스트를 자동화하려고하는데, 파이어 폭스 53을 사용하여 셀레늄 3.4를 사용하고 있습니다. 내 테스트 코드에 아무런 문제가 보이지 않습니다. 요소를 찾을 수는 없습니다이 테스트를 실행 한 후 :}

public class TC001_LoginWithInvalidCredentials { 

WebDriver driver ; 
@BeforeTest 
public void setUp(){ 
    System.setProperty("webdriver.gecko.driver",System.getProperty("user.dir")+"/Drivers/geckodriver.exe"); 
    driver = new FirefoxDriver(); 
    driver.get("http://automationpractice.com/index.php?"); 
} 
@Test 
public void LoginWithInvalidCredentials(){ 
    driver.findElement(By.xpath(".//*[@id='header']/div[2]/div/div/nav/div[1]/a")).click(); 
    driver.findElement(By.id("email")).sendKeys("test@gmail.com"); 
    driver.findElement(By.id("passwd")).sendKeys("passwrd"); 
    driver.findElement(By.xpath(".//*[@id='SubmitLogin']")).click(); 

    Assert.assertEquals(driver.findElement 
      (By.xpath(".//*[@id='center_column']/div[1]/ol/li")).getText(), "Authentication failed."); 

} 

@AfterTest 
public void endTest(){ 
    driver.close(); 

}

DOM에있는 요소가 나타날 때까지 기다린 후 클릭하십시오 :

WebDriverWait wait = new WebDriverWait(driver, 10); 
wait.until(ExpectedConditions.elementToBeClickable(By.linkText("Sign in"))).click(); 
wait.until(ExpectedConditions.elementToBeClickable(By.id("email"))).sendKeys("test@gmail.com");
