I've written basic code which goes to a specific URL then changes the country and currency. I now want to tidy my code up and make it easier to maintain.
I've not used page object model before so have been reading about it. I understand the basic concepts of creating another class within the project and creating an extension to page objects that are used to initialize the web elements.
So essentially all my FindElements will be stored in a separate class. I've created two Classes within a PageObjects folder. HomePage and PreferencePage.
Below code is working and does exactly as I expect.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.UI;
using OpenQA.Selenium.Interactions;
using System.Threading;
namespace Exercise1
{
class Program
{
static void Main(string[] args)
{
IWebDriver webDriver = new ChromeDriver();
webDriver.Navigate().GoToUrl("http://www.asos.com/men/");
webDriver.Manage().Window.Maximize();
webDriver.FindElement(By.XPath(".//button[#data-testid='country-selector-btn']")).Click();
WebDriverWait wait = new WebDriverWait(webDriver, TimeSpan.FromSeconds(5));
IWebElement country = wait.Until(ExpectedConditions.ElementExists(By.Id("country")));
SelectElementFromDropDown(country, "India");
IWebElement currency = wait.Until(ExpectedConditions.ElementExists(By.Id("currency")));
SelectElementFromDropDown(currency, "$ USD");
webDriver.FindElement(By.XPath(".//button[#data-testid='save-country-button']")).Click();
webDriver.Quit();
}
private static void SelectElementFromDropDown(IWebElement ele, string text)
{
SelectElement select = new SelectElement(ele);
select.SelectByText(text);
}
}
}
Now I want to implement Page Object Model. I have created my main TestClass, along with a HomePage and PreferencePage class. I'm unsure of how to implement the next bit. I know my TestClass will be making a call to the HomePage for the URL and PreferencePage for the country and currency but I'm unsure how the implementation would look.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
namespace Exercise1
{
class TestClass
{
private IWebDriver driver;
public void SetUp()
{
IWebDriver webDriver = new ChromeDriver();
webDriver.Manage().Window.Maximize();
}
public void ChangePreferences()
{
Homepage home = new Homepage(driver);
home.goToPage();
PreferencePage preference = home.GoToPreferencePage();
UpdateCountry = preference.UpdateCountryPreference();
UpdateCurrency = preference.UpdateCurrencyPreference();
UpdatePreference = preference.PreferenceUpdated();
}
}
}
HomePage class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Exercise1
{
class HomePage
{
private IWebDriver driver;
public HomePage(IWebDriver driver)
{
this.driver = driver;
PageFactory.InitElements(driver, this);
}
public void goToPage()
{
driver.Navigate().GoToUrl("http://www.asos.com/men/");
}
}
}
Preference page
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Exercise1.PageObjects
{
class PreferencePage
{
private IWebDriver driver;
public UpdateCountry(string text)
{
WebDriverWait wait = new WebDriverWait(webDriver, TimeSpan.FromSeconds(5));
IWebElement country = wait.Until(ExpectedConditions.ElementExists(By.Id("country")));
SelectElementFromDropDown(country, "India");
}
public void UpdateCurrency()
{
IWebElement currency = wait.Until(ExpectedConditions.ElementExists(By.Id("currency")));
SelectElementFromDropDown(currency, "$ USD");
}
public void ClickPreference()
{
webDriver.FindElement(By.XPath(".//button[#data-testid='save-country-button']")).Click();
}
}
}
it would look like that:
class TestClass
{
private IWebDriver driver;
public void SetUp()
{
..
}
public TestChangePreferences()
{
//actual test
ChangePreferences();
}
public void ChangePreferences()
{
.......
}
}
I'd wrap it with a testing framework such as NUnit for better test management and tools.
this could give you a pretty good example:

I'm not sure it makes sense to use ExtentReports for you automation frameworkwritten in C#.
Starting from v.4 ExtentReports they don't support it anymore.
The reply from them was that they were going to support only Java.
This is a feature of NUnit 3. You should install the Visual Studio Test Adapter ( https://github.com/nunit/docs/wiki/Visual-Studio-Test-Adapter ) via NuGet package named "NUnit3TestAdapter" to get the OneTimeSetup to work.
Then you can check your implementation of the report :-)
Maybe your report is created in the temporary folder (after some time I found it, using windows search). I have the same when running my tests, using Visual Studio. Try to run your test, using Nunit console application. Download it separately, then run tests using console command
nunit "path to compiled .dll with tests"
In this case, I think you should found reports near .dll file. This happens in my case (using Allure reports).
I've updated packages from my project on Mac and find out that PageObjects has been moved to SeleniumExtras. I struggle to use it but the error "System.NullReferenceException : Object reference not set to an instance of an object." is shown.
Nevertheless, the same element can be found through FindElement. Currently, I run out of ideas and would appreciate the help.
Thanks!

Got solution:
Add all DotNetSeleniumExtras through NuGet Packages: PageObjects and PageObjects.Core;
Add namespaces:
using FindsByAttribute = SeleniumExtras.PageObjects.FindsByAttribute;
using How = SeleniumExtras.PageObjects.How;
So I wrote a test and am trying to run it but when I right click it and hit, "Run Selected Test" the green loading bar moves up for less than a second and just stops. Fairly new to this so excuse my ignorance.
Test being ignored & not running.
This is the stack trace I get from the test output when I try to run it.

My test projects .csproj file was corrupted. Corrected and tests are visibly running again.
I am running my selenium script on amazon work space, scripting language using is c#

Can anyone please help me on this.
Thanks in Advance
I have rearranged my class files and Webdriver variable so I can use Context Injection to share the Webdriver variable between steps. Before I was using SetupFixture, Setup and TearDown which is not correct for BDD. Trying Context Injection now with BeforeAllTests, BeforeTestRun etc.

How do I resolve this please?
I think it is complaining that objectContainer.RegisterInstanceAs does not have any value, it is Null. It has not been instantiated?
Thanks, Riaz
your problem is that you have a typo in your constructor. This:
public BeforeAllTests(IObjectContainer container)
{
this.objectContainer = objectContainer;
}
should be
public BeforeAllTests(IObjectContainer container)
{
this.objectContainer = container;
}
you are not using the container instance given in the constructor, you are simply setting the objectContainer to itself.
