Sharing the dirver object initialized in base class to that of page classes

In the POM model, we ideally tend to have the driver object being initialized in base class. And in the page classed we pass this driver object. But the problem is to avoid passing this object as well and the tests should continue to work in parallel too in XUNit framework. Below is the structure
public class BaseClass:IDisposable
{
public IWebDriver Driver{get;set;}
public BaseClass()
{
if(Driver == null)
{
Driver = new ChromeDriver();
}
}
}
public class Page1:BaseClass
{
public void method1()
{
this.Driver.Navigate.GoToUrl("http://www.google.com")
}
}
public class Page2:BaseClass
{
public void method2()
{
this.Driver.Navigate.GoToUrl("http://www.stackoverflow.com")
}
}
public class TestClass
{
[Fact]
public void Test1()
{
new Page1().method1();
new Page2().method2();
}
}
Now in the above structure if the test executes two instances of the driver object will be created because of OOPS. If we need to avoid this we can the Driver object as static and reinitialize it if the object is null. But this will again fail when we run multiple tests in parallel. Any suggession? Thing I am trying to achieve is that full encapsulation where the Test class should not have any access to Selenium objects. These objects should be only accessible in Page class or its Operation class if we have any.

We need to ensure we create a driver singleton and its threadsafe to run parallely
[TestClass]
public class UnitTest1 : TestBase
{
[TestMethod]
public void TestMethod1()
{
new Page1().method1();
new Page2().method2();
Driver.Testcleanup();
}
[TestMethod]
public void TestMethod2()
{
new Page1().method1();
new Page2().method2();
Driver.Testcleanup();
}
public class Page1
{
public void method1()
{
Driver.Instance.Navigate().GoToUrl("http://www.google.com");
}
}
public class Page2
{
public void method2()
{
Driver.Instance.Navigate().GoToUrl("http://www.google.com");
}
}
}
Driver Class will handle the initialization of the singleton and cleanup
public sealed class Driver
{
[ThreadStatic]
public static IWebDriver driver = null;
public static IWebDriver Instance
{
get
{
if (driver == null)
{
driver = new ChromeDriver();
}
return driver;
}
}
public static void Testcleanup()
{
driver.Quit();
driver = null;
}
}

C# Extending Selenium Webdriver Class

I would like to add a static string property that will track the name of the current test running. I figured the best way to go about this was to use the WebDriver since it is the only object that is carried throughout all of my page objects.
Is there a way to extend the WebDriver class to add a string property that I can set?
EDIT: Since WebDriver uses the IWebDriver interface rather would I extend the interface perhaps?
EDIT #2: Adding example of what I currently have to load my WebDriver:
protected static NLog.Logger _logger = LogManager.GetCurrentClassLogger();
protected static IWebDriver _driver;
/// <summary>
/// Spins up an instance of FireFox webdriver which controls the browser using a
/// FireFox plugin using a stripped down FireFox Profile.
/// </summary>
protected static void LoadDriver()
{
ChromeOptions options = new ChromeOptions();
try
{
var profile = new FirefoxProfile();
profile.SetPreference("browser.helperApps.neverAsk.saveToDisk", "application/octet-stream doc xls pdf txt");
_driver = new FirefoxDriver(profile);
_driver.Navigate().GoToUrl("http://portal.test-web01.lbmx.com/login?redirect=%2f");
}
catch(Exception e)
{
Console.WriteLine(e.Message);
throw;
}
}

Ok let's stop the half answer practice (That is the full implementation of generic IWebDriver) after that you can call all the regular methods like you use in standard driver + you have your additional CurrentTest variable.
you can add more constructors for best compatibility.
class MyWebDriver<T> where T : IWebDriver, new()
{
IWebDriver driver;
public string CurrentTest { get; set; }
public MyWebDriver()
{
driver = new T();
}
public void Dispose()
{
this.driver.Dispose();
}
public IWebElement FindElement(By by)
{
return this.driver.FindElement(by);
}
public ReadOnlyCollection<IWebElement> FindElements(By by)
{
return this.driver.FindElements(by);
}
public void Close()
{
this.driver.Close();
}
public void Quit()
{
this.driver.Quit();
}
public IOptions Manage()
{
return this.driver.Manage();
}
public INavigation Navigate()
{
return driver.Navigate();
}
public ITargetLocator SwitchTo()
{
return this.SwitchTo();
}
public string Url
{
get
{
return this.driver.Url;
}
set
{
this.driver.Url = value;
}
}
public string Title
{
get
{
return this.driver.Title;
}
}
public string PageSource
{
get
{
return this.driver.PageSource;
}
}
public string CurrentWindowHandle
{
get
{
return this.driver.CurrentWindowHandle;
}
}
public ReadOnlyCollection<string> WindowHandles
{
get
{
return this.WindowHandles;
}
}
}
public class MyTest
{
public void main()
{
MyWebDriver<FirefoxDriver> driver = new MyWebDriver<FirefoxDriver>();
driver.CurrentTest = "Entering to google website with Firefox Driver";
driver.Navigate().GoToUrl("www.google.com");
}
}

You will need to wrap the WebDriver using the "Decorator" design pattern.
public class MyWebDriver : IWebDriver
{
private IWebDriver webDriver;
public string CurrentTest { get; set; }
public MyWebDriver(IWebDriver webDriver)
{
this.webDriver = webDriver
}
public Method1()
{
webDriver.Method1();
}
public Method2()
{
webDriver.Method2();
}
...
}
And then pass in whichever driver you are using at the time.
var profile = new FirefoxProfile();
MyWebDriver driver = new MyWebDriver(new FirefoxDriver(profile));
This way you are delegating the interface methods of IWebDriver to FirefoxDriver but can add whatever additions are appropriate.

what if you do something like
class MyWebDriver
{
private IWebDriver driver;
private static string CurrentTest;
....
//make constractors / getters, setters
}
execution
MyWebDriver d = new MyWebDriver(....)
...

Just use a sub class that has WebDriver as its parent:
public class MyWebDriver : WebDriver
{
private string _currentTest;
}
Then you can use MyWebDriver everywhere and set _currentTest as needed.

How to invoke unit test class in reflection c#

I have a class which is decorated with [TestFixture] attribute and this class contains methods that are decorated with [Test] attribute, each method signature is
public void MethodName([ValueSource("TestConfigurations")] TestConfiguration tConf)
also there are set up and tear down methods
[TestFixtureSetUp]
public void TestFixtureSetUp()
{
}
[SetUp]
public void TestSetUp() { }
[TearDown]
public void TestTearDown()
{
}
[TestFixtureTearDown]
public void TestFixtureTearDown()
{
}
how can I run this unit test class via reflection in c#?
Thank you in advanced

Something like:
public static class RunUnitTestsClass<TUnitTests> where TUnitTests : new()
{
private static IEnumerable<MethodInfo> WithAttribute<TAttribute>()
{
return typeof(TUnitTests).GetMethods().Where(method => method.GetCustomAttributes(typeof(TAttribute), true).Any());
}
private static void RunWithAttribute<TAttribute>()
{
var unitTests = new TUnitTests();
foreach (var method in WithAttribute<TAttribute>())
method.Invoke(unitTests, new object[0]);
}
public static void RunTestFixtureSetup()
{
RunWithAttribute<TestFixtureSetUp>();
}
// same for the rest of them
public static void RunTests(TestConfiguration tConf)
{
var unitTests = new TUnitTests();
foreach (var method in WithAttribute<Test>())
method.Invoke(unitTests, new []{tConf});
}
}

I have created an ordered test and prioritized the tests in the order of execution . But it is invoking two instances of the driver that means two times the browser.
My question is to How to share a single driver object across all selenium unit tests ?? create at the start and close the driver at the end.
Thanks.

HI If you are using using NUnit.Framework;
The code Execution plan is like below.
For First Test Case
[TestFixtureSetup] ---->For each test case this will work so here we can
initialize the driver instance.
[TestMethod] ----->test method will goes here
[TearDown] -----> clean up code
**For Second Test Case**
[TestFixtureSetup]
[TestMethod]
[TearDown]
If you have to run both test case in one browser instance
Dont close the driver inside TearDown.
AND INITIALIZE THE DRIVER UNDER TextFixtureSetup
[TestFixture()]
public class TestClass
{
[TestFixtureSetUp]
public void Init()
{
Driver.initialize(new InternetExplorerDriver());
}
[TearDown]
public void Close()
{
//dont do any driver.close()
}
[TestMethod]
public void TestCase001()
{
//your code goes here
}
[TestMethod]
public void TestCase002()
{
//your code goes here
}

You can take a look on this thread, where I answered how I did it: How to run multiple test methods in same browser instance without closing it (C#, SeleniumWebDriverz NUnit)?
Basically, I used:
using Microsoft.VisualStudio.TestTools.UnitTesting;
Instead of:
using NUnit.Framework;
So now I have next hierarchy:
[TestFixture]
[TestFixtureSetup] // this is where I initialize my WebDriver " new FirefoxDriver(); "
[Test] //first test
[Test] //second test
[Test] //third test
[TestFixtureTearDown] // this is where I close my driver
With this changes, my browser will open only once for TestFixture (or TestClass if you use "using Microsoft.VisualStudio.TestTools.UnitTesting;") and all [Test]-s from that fixture will run in that same browser instance. After all tests are done, browser will close.
Hope this will help someone else in future. Ask me if you need additional help.

I used NUnit Framework:
using NUnit.Framework;
I then set up my WebDriver initialisation, test and teardown like this:
[TestFixture()]
class NUnitSeleniumTests
{
[OneTimeSetUp]
public void Init()
{
driverIE = new InternetExplorerDriver(ConfigurationManager.AppSettings["IEDriver"]);
driverIE.Manage().Window.Maximize();
// other setup logic
}
[Test]
public void TestMethod1()
{
// Test logic
}
[Test]
public void TestMethod2()
{
// Test logic
}
...
...
...
[Test]
public void TestMethodN()
{
// Test logic
}
[OneTimeTearDown]
public void Close()
{
driverIE.Close();
}
}
When I Run All tests, the WebDriver driverIE is initialised. All tests then execute in that WebDriver instance before the WebDriver instance is closed at the end of the test run.
The tests execute in alphabetical order by default; each test can also execute in isolation.

Xunit create new instance of Test class for every new Test ( using WebDriver and C#)

Is there any way to run multiple tests in same browser using Webdriver (Selenium) using Xunit, , at present xunit launches new browser for every new test , below is the sample code
public class Class1
{
private FirefoxDriver driver;
public Class1()
{
driver = new FirefoxDriver();
}
[Fact]
public void Test()
{
driver.Navigate().GoToUrl("http://google.com");
driver.FindElementById("gbqfq").SendKeys("Testing");
}
[Fact]
public void Test2()
{
driver.Navigate().GoToUrl("http://google.com");
driver.FindElementById("gbqfq").SendKeys("Testing again");
}
}

While I don't know Selenium, I do know that xUnit.net creates a new instance of your test class for every test method, so that probably explains why you are seeing the behaviour you're reporting: the driver field is initialized anew for each test method, because the constructor is invoked every time.
In order to reuse a single FirefoxDriver instance, you can use xUnit.net's IUseFixture<T> interface:
public class Class1 : IUseFixture<FirefoxDriver>
{
private FirefoxDriver driver;
public void SetFixture(FirefoxDriver data)
{
driver = data;
}
[Fact]
public void Test()
{
driver.Navigate().GoToUrl("http://google.com");
driver.FindElementById("gbqfq").SendKeys("Testing");
}
[Fact]
public void Test2()
{
driver.Navigate().GoToUrl("http://google.com");
driver.FindElementById("gbqfq").SendKeys("Testing again");
}
}

after some investigation able to find the solution here it is and also updated FirefoxDriver to IWebDriver::
public class SampleFixture : IDisposable
{
private IWebDriver driver;
public SampleFixture()
{
driver = new FirefoxDriver();
Console.WriteLine("SampleFixture constructor called");
}
public IWebDriver InitiateDriver()
{
return driver;
}
public void Dispose()
{
// driver.Close();
driver.Quit();
Console.WriteLine("Disposing Fixture");
}
}
public class Class1 : IUseFixture<SampleFixture>
{
private IWebDriver driver;
public void SetFixture(SampleFixture data)
{
driver = data.InitiateDriver();
}
[Fact]
public void Test()
{
driver.Navigate().GoToUrl("http://google.com");
driver.FindElement(By.Id("gbqfq")).SendKeys("Testing");
}
[Fact]
public void Test2()
{
driver.Navigate().GoToUrl("http://google.com");
driver.FindElement(By.Id("gbqfq")).SendKeys("Testing again");
}
}

IUseFixture doesn't exist any more and seems replaced by IClassFixture. But I can't directly inject the FirefoxDriver as posted by #Mark Seemann:
public class DashboardCategoryBoxes : IClassFixture<FirefoxDriver> {
IWebDriver driver;
public DashboardCategoryBoxes(FirefoxDriver driver) {
//this.driver = wrapper.Driver;
this.driver = driver;
}
}
This throw an error
System.AggregateException : One or more errors occurred. (Class fixture type 'OpenQA.Selenium.Firefox.FirefoxDriver' may only define a single public constructor.) (The following constructor parameters did not have matching fixture data: FirefoxDriver driver)
---- Class fixture type 'OpenQA.Selenium.Firefox.FirefoxDriver' may only define a single public constructor.
---- The following constructor parameters did not have matching fixture data: FirefoxDriver driver
As a workaround, we could create some wrapper class without constructor
public class FirefoxWrapper {
FirefoxDriver driver = new FirefoxDriver();
public FirefoxWrapper Driver {
get { return driver; }
}
}
and fetch the driver from there
public class DashboardCategoryBoxes : IClassFixture<FirefoxWrapper> {
IWebDriver driver;
public DashboardCategoryBoxes(FirefoxWrapper wrapper) {
driver = wrapper.Driver;
}
}
