什么是使用Selenium PageObject Design Pattern的最佳方式 [英] What's the best way to use Selenium PageObject Design Pattern
问题描述
许多硒示例仅显示在Java中，.NET的API绑定并不总是与之相似，因为它们是由于限制和标准集按某些语言。
在.Net Selenium Web驱动程序中使用PageFactory的PageObject设计模式的最佳方法是什么？
最终，我希望我的PageObjects处理更多的功能，而不是使用PageObject IWebElements的NUnit测试。
下面是我正在如何创建我的测试的例子向前移动。
public class LoginPage
{
private IWebDriver webDriver;
[FindsBy（How = How.Id，Using =ctl00_ctl00_ctl00_insideForm_insideForm_content_txtPassword）]
public IWebElement Password {get;组; }
[FindsBy（How = How.Id，Using =ctl00_ctl00_ctl00_insideForm_insideForm_content_cmdSubmit）]
public IWebElement SubmitButton {get;组; }
[FindsBy（How = How.Id，Using =ctl00_ctl00_ctl00_insideForm_insideForm_content_txtUserName）]
public IWebElement UserName {get;组;
public LoginPage（）{}
public LoginPage（IWebDriver webDriver）
{
this.webDriver = webDriver;
if（！webDriver.Url.Contains（Login.aspx））
{
throw new StaleElementReferenceException（这不是登录页面） ;
}
PageFactory.InitElements（webDriver，this）;
}
public HomePage signIn（string username，string password）
{
UserName.SendKeys（username）;
Password.SendKeys（password）;
SubmitButton.Submit（）;
//即使我为这个
创建一个NUnit测试//当我尝试并返回新对象
时，页面加载仍然发生问题HomePage homePage = new HomePage（webDriver） ;
PageFactory.InitElements（webDriver，homePage）;
return homePage;
}
}
目前我正在做什么NUnit：
[TestFixture]
public class LoginPageTest：TestBase
{
private IWebDriver driver ;
private LoginPage loginPage;
private HomePage homePage;
[SetUp]
[描述（设置测试夹具页面对象并导航到登录页面）]
public void SetUp（）
{
driver = StartDriver（）;
Log.Info（Driver started）;
driver.Navigate（）。GoToUrl（http：//+ Environment +）;
loginPage = new LoginPage（）;
PageFactory.InitElements（driver，loginPage）;
//driver.Navigate（）。Refresh（）;
}
[测试]
[说明（进入无效凭证并断言显示正确的错误消息。）]
public void SubmitFormInvalidCredentials（）
{
loginPage.UserName.SendKeys（invalid）;
loginPage.Password.SendKeys（invalid）;
loginPage.SubmitButton.Click（）;
IWebElement invalidCredentials = driver.FindElement（By.Id（ctl00_ctl00_ctl00_insideForm_insideForm_ctl02_title））;
Assert.AreEqual（无效的用户名或密码，invalidCredentials.Text ）;
}
[测试]
[说明（输入有效的凭据并声明用户被带到主页）]
public void SubmitFormValidCredentials（）
{
login Page.UserName.SendKeys（ 有效）;
loginPage.Password.SendKeys（valid）;
loginPage.SubmitButton.Click（）;
homePage = new HomePage（）;
PageFactory.InitElements（driver，homePage）;
Assert.AreEqual（pattest，homePage.Username.Text）;
}
}
大部分文章和博文我发现selenium webdriver设计模式发出矛盾以前的帖子我发现。
那么正确的方法是什么？
为了摆脱这一点，我甚至给了PageObject设计模式一个尝试。
[测试]
[说明（使用PageObject Design Pattern登录）]
public void Login（）
{
loginPage = new LoginPage（driver）;
HomePage signIn = loginPage.SignIn（pattest，pattest）;
}
在我的LoginPage中
public LoginPage（IWebDriver驱动程序）
{
this.driver = driver;
如果（！driver.Url.Contains（Login.aspx））
{
抛出新的ElementNotFoundException（这不是登录页面）;
}
PageFactory.InitElements（driver，this）;
}
public HomePage SignIn（string username，string password）
{
UserName.SendKeys（username）;
Password.SendKeys（password）;
SubmitButton.Click（）;
return new HomePage（driver）;
}
当然要显示我的HomePage应该如何与其构造函数一起启动：
public HomePage（IWebDriver d）
{
webDriver = d;
//我需要使用这个，因为它不会在我通过网络驱动程序的constorctor等待我的页面加载。
var wait = new WebDriverWait（webDriver，TimeSpan.FromSeconds（60））;
try
{
wait.Until（driver => driver.FindElement（By.Id（ctl00_ctl00_ctl00_insideForm_insideForm_loginStatus）））;
}
catch（异常e）
{
抛出新的ElementNotFoundException（这不是主页）;
}
PageFactory.InitElements（webDriver，this）;
}
如何通过测试有效地使用WebDriver PageObject设计模式。
我无法理解这一点。
使用 PageFactory.InitElements（_driver，此）;在您的基页类的构造函数上：
public class页
{
public IWebDriver _driver;
public page（IWebDriver驱动程序）
{
this._driver = driver;
PageFactory.InitElements（_driver，this）;
}
}
请参阅 PageFactory文档
I'm creating tests using Selenium 2 Web Driver with C#.Net. After reading through a lot of the Selenium documentation, I am left still feeling unsure on how to go about testing using the PageObject design patterns.
Many of the selenium examples are only shown in Java and the API bindings for .Net are not always as similar as one would think they are due to limitations and the standards set by certain languages.
What is the best way to use the PageObject design pattern with PageFactory in .Net Selenium Web Driver?
Eventually, I want my PageObjects to handle more functionality, rather than my NUnit tests using the PageObject IWebElements.
Below is an example of how I am currently going to create my tests moving forward.
public class LoginPage
{
private IWebDriver webDriver;
[FindsBy(How = How.Id, Using = "ctl00_ctl00_ctl00_insideForm_insideForm_content_txtPassword")]
public IWebElement Password { get; set; }
[FindsBy(How = How.Id, Using = "ctl00_ctl00_ctl00_insideForm_insideForm_content_cmdSubmit")]
public IWebElement SubmitButton { get; set; }
[FindsBy(How = How.Id, Using = "ctl00_ctl00_ctl00_insideForm_insideForm_content_txtUserName")]
public IWebElement UserName { get; set; }
public LoginPage() { }
public LoginPage(IWebDriver webDriver)
{
this.webDriver = webDriver;
if(!webDriver.Url.Contains("Login.aspx"))
{
throw new StaleElementReferenceException("This is not the login page");
}
PageFactory.InitElements(webDriver, this);
}
public HomePage signIn(string username, string password)
{
UserName.SendKeys(username);
Password.SendKeys(password);
SubmitButton.Submit();
// Even if i create a NUnit test for this
// Issue with page loading still occures when I try and return new object
HomePage homePage = new HomePage(webDriver);
PageFactory.InitElements(webDriver, homePage);
return homePage;
}
}
At the moment this is what I am currently doing with NUnit:
[TestFixture]
public class LoginPageTest : TestBase
{
private IWebDriver driver;
private LoginPage loginPage;
private HomePage homePage;
[SetUp]
[Description("Sets up the test fixture page objects and navigates to the login page.")]
public void SetUp()
{
driver = StartDriver();
Log.Info("Driver started");
driver.Navigate().GoToUrl("http://" + Environment + ");
loginPage = new LoginPage();
PageFactory.InitElements(driver, loginPage);
//driver.Navigate().Refresh();
}
[Test]
[Description("Enters invalid credentials and asserts that a correct error message is displayed.")]
public void SubmitFormInvalidCredentials()
{
loginPage.UserName.SendKeys("invalid");
loginPage.Password.SendKeys("invalid");
loginPage.SubmitButton.Click();
IWebElement invalidCredentials = driver.FindElement(By.Id("ctl00_ctl00_ctl00_insideForm_insideForm_ctl02_title"));
Assert.AreEqual("Invalid user name or password", invalidCredentials.Text);
}
[Test]
[Description("Enters valid credentials and asserts that the user is taken to the home page.")]
public void SubmitFormValidCredentials()
{
loginPage.UserName.SendKeys("valid");
loginPage.Password.SendKeys("valid");
loginPage.SubmitButton.Click();
homePage = new HomePage();
PageFactory.InitElements(driver, homePage);
Assert.AreEqual("pattest", homePage.Username.Text);
}
}
Most of the articles and blog posts I find for selenium webdriver Design Patterns give off contradictions to previous posts I find.
So, what is the right way?
To top this off, I even gave the PageObject design pattern a try.
[Test]
[Description("Login using PageObject Design Pattern")]
public void Login()
{
loginPage = new LoginPage(driver);
HomePage signIn = loginPage.SignIn("pattest", "pattest");
}
Inside my LoginPage
public LoginPage(IWebDriver driver)
{
this.driver = driver;
if (!driver.Url.Contains("Login.aspx"))
{
throw new ElementNotFoundException("This is not the login page");
}
PageFactory.InitElements(driver, this);
}
public HomePage SignIn(string username, string password)
{
UserName.SendKeys(username);
Password.SendKeys(password);
SubmitButton.Click();
return new HomePage(driver);
}
And, of course to show how my HomePage should be initiated with its Constructor:
public HomePage(IWebDriver d)
{
webDriver = d;
// I need to use this as its not freaking waiting for my Page to load when I pass the webdriver in the consturctor.
var wait = new WebDriverWait(webDriver, TimeSpan.FromSeconds(60));
try
{
wait.Until(driver => driver.FindElement(By.Id("ctl00_ctl00_ctl00_insideForm_insideForm_loginStatus")));
}
catch(Exception e)
{
throw new ElementNotFoundException("This is not the home page.");
}
PageFactory.InitElements(webDriver, this);
}
How do I use WebDriver PageObject design pattern effectively with testing. I can't figure this out.
Use PageFactory.InitElements(_driver, this); on the constructor of your base page class:
public class Page
{
public IWebDriver _driver;
public Page(IWebDriver driver)
{
this._driver = driver;
PageFactory.InitElements(_driver, this);
}
}
Please see the PageFactory documentation
