[英]Selenium Username Password Code Error
I am writing a code that enters the username and password into a URL and submits that page. 我正在编写一个将用户名和密码输入URL并提交该页面的代码。 but I keep getting this error
但我不断收到这个错误
"Caused by: org.openqa.selenium.remote.ErrorHandler$UnknownServerException:
Unable to locate element: {"method":"name","selector":"username"}"
Below is the code 下面是代码
package org.openqa.selenium.example;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
public class LoginPage {
private final WebDriver driver;
public LoginPage(WebDriver driver) {
this.driver = driver;
// Check that we're on the right page.
if (!"Outreach Configuration".equals(driver.getTitle())) {
// Alternatively, we could navigate to the login page, perhaps logging out first
throw new IllegalStateException("This is not the login page");
}
}
// The login page contains several HTML elements that will be represented as WebElements.
// The locators for these elements should only be defined once.
// By usernameLocator = By.name("username");
// By passwordLocator = By.name("password");
// By loginButtonLocator = By.name("submit");
// The login page allows the user to type their username into the username field
public LoginPage typeUsername(String username) {
// This is the only place that "knows" how to enter a username
driver.findElement(By.name("username")).sendKeys(username);
// Return the current page object as this action doesn't navigate to a page represented by another PageObject
return this;
}
// The login page allows the user to type their password into the password field
public LoginPage typePassword(String password) {
// This is the only place that "knows" how to enter a password
//driver.findElement(passwordLocator).sendKeys(password);
driver.findElement(By.name("password")).sendKeys(password);
// Return the current page object as this action doesn't navigate to a page represented by another PageObject
return this;
}
// The login page allows the user to submit the login form
public HomePage submitLogin() {
// This is the only place that submits the login form and expects the destination to be the home page.
// A seperate method should be created for the instance of clicking login whilst expecting a login failure.
// driver.findElement(By.name("submit")).submit();
// Return a new page object representing the destination. Should the login page ever
// go somewhere else (for example, a legal disclaimer) then changing the method signature
// for this method will mean that all tests that rely on this behaviour won't compile.
return new HomePage(driver);
}
// The login page allows the user to submit the login form knowing that an invalid username and / or password were entered
public LoginPage submitLoginExpectingFailure() {
// This is the only place that submits the login form and expects the destination to be the login page due to login failure.
// driver.findElement(By.name("submit")).submit();
// Return a new page object representing the destination. Should the user ever be navigated to the home page after submiting a login with credentials
// expected to fail login, the script will fail when it attempts to instantiate the LoginPage PageObject.
return new LoginPage(driver);
}
// Conceptually, the login page offers the user the service of being able to "log into"
// the application using a user name and password.
public HomePage loginAs(String username, String password) {
// The PageObject methods that enter username, password & submit login have already defined and should not be repeated here.
typeUsername(username);
typePassword(password);
return submitLogin();
}
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
// And now use this to visit Google
driver.get("URL Goes Here");
LoginPage login = new LoginPage(driver);
HomePage a=login.loginAs("username","Password");
}
}
I reffered it from http://code.google.com/p/selenium/wiki/PageObjects 我从http://code.google.com/p/selenium/wiki/PageObjects引用了它
Try to add 尝试添加
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
before HomePage a=login.loginAs("username","Password");
在
HomePage a=login.loginAs("username","Password");
之前HomePage a=login.loginAs("username","Password");
. 。
It is not quite good approach, but it will help to find out where is the problem. 这不是一个很好的方法,但是它将有助于找出问题所在。 This is just a pause before next step.
这只是下一步之前的暂停。 You shouldn't use it in future, because it is not pretty good practice.
将来您不应该使用它,因为它不是很好的做法。 It is better to use
wait for condition
check this out for more information. 这是更好地使用
wait for condition
检查这出更多的信息。
