Applitools + Specflow+ Selenium + C#

I'm asking for help, I'm already desperate.
I made a simple test script with Gherkin and generated the steps. I want to integrate Applitools into this process, that is, to use eyes.Check() method. But no matter how hard I try, every time I initialize the eyes object, I get the following error: Method not found: "Applitools.BatchInfo Applitools.IEyesBase.get_Batch().
Examples on applitools.com don't fit me, because the same Ruby implementation doesn't work for me, and the C# example doesn't involve using Gherkin.
My scenario:
#Default.Target.Environment:Edu
Feature: LoginScenario
#INWK.LP.C0002
Scenario: L001_Login
When I open Web Site
And I login as user my_email#edu.hse.ru with pass 12345678
Then I close browser
My steps:
using System.Drawing;
using Applitools;
using Applitools.Selenium;
using Lms.Helpers;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using TechTalk.SpecFlow;
using NUnit.Framework;
using Configuration = Applitools.Selenium.Configuration;
namespace Lms.Steps
{
[TestFixture]
[Binding]
public class LoginInLmsSteps
{
private IWebDriver driver;
private LoginHelper loginHelper;
private Eyes eyes;
private EyesRunner runner;
private string Url => "https://lms.hse.ru/";
[Before]
[SetUp]
public void BeforeEach()
{
Configuration config = new Configuration();
config.SetApiKey("my_key");
config.SetBatch(new BatchInfo("LMS Batch"));
config.AddBrowser(800, 600, BrowserType.CHROME);
runner = new ClassicRunner();
eyes = new Eyes(runner);
eyes.SetConfiguration(config);
}
[When(#"I open Web Site")]
public void WhenIOpenWebSite()
{
driver = new ChromeDriver();
driver.Url = Url;
}
[When(#"I login as user (.*) with pass (.*)")]
public void WhenILoginAsUserWithPass(string username, string password)
{
eyes.Open(driver, "LMS", "Login test", new Size(800, 600));
eyes.CheckWindow("Login Page");
loginHelper.Login(username, password);
eyes.CloseAsync();
}
[Then(#"I close browser")]
public void ThenICloseBrowser()
{
driver.Quit();
driver = null;
}
[TearDown]
public void AfterEach()
{
// If the test was aborted before eyes.close was called, ends the test as aborted.
eyes.AbortIfNotClosed();
//Wait and collect all test results
TestResultsSummary allTestResults = runner.GetAllTestResults();
}
}
}
That is, I catch the error already at the setup stage
I would be grateful for any help!

Run Selenium Grid C# Project in Visual Studio

I'm implemented Nunit selenium C# testing in visual studio (Console Application n Class Library). My project in visual studio is console application. I started the selenium grid using

}
I had tried execute using Test Explorer but it does not open any browser. I"m following this tutorial.
Questions:
How to run the project with browser open and see all actions?
How to run using Nunit-console-runner.
Please help me. Thanks.

I assume that:
1. You have tried your code locally and your test is opening the browser when you run it on your machine without the grid.
2. Your nodes are set up and registered with the hub.
You need to:
1. Use RemoteWebDriver:
var uri = 'uri_to_your_grid_hub';
var capabilities = new ChromeOptions().ToCapabilities();
var commandTimeout = TimeSpan.FromMinutes(5);
var driver = new RemoteWebDriver(new Uri(uri),capabilities,commandTimeout)
Add the attribute to a class: [Parallelizable(ParallelScope.Self)] in order to run your tests in parallel with other test classes.
In order to verify whether the hub is running, open the browser and navigate to http://localhost:4444 on the hub machine.
Sources:
How can I run NUnit(Selenium Grid) tests in parallel?
Selenium Grid in C#
Useful C# WebDriver examples
Selenium Grid set up

I haven't used grid in .Net but here my answer:
your command is just register a hub, which needs to keep running (open a browser and test it is working)
you need to register your nodes under that hub (different ports) (open a browser and test it is working)
in your code, you should use "RemoteWebDriver" to connect to the hub.
something along these lines (it is in java but I hope it gives you a starting point)
public class Gmail
{
public WebDriver driver=null;
#Parameters("browser") //testng.xml
#Test()
public void GmailTest(String browser)
{
System.out.println("Gmail " + browser);
// RemoteWebdriver
DesiredCapabilities cap = null;
if(browser.equals("firefox")){
cap = DesiredCapabilities.firefox();
cap.setBrowserName("firefox");
cap.setPlatform(Platform.ANY);
}else if (browser.equals("iexplore")){
cap = DesiredCapabilities.internetExplorer();
cap.setBrowserName("iexplore");
cap.setPlatform(Platform.WINDOWS);
}
driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),cap);
driver.get("http://gmail.com");
driver.findElement(By.id("Email")).sendKeys("abcd");
driver.quit();
}
I hope this helps.good luck

How to integrate Appium with C#?

I am unable to find a single post where i can automate mobile testing with appium in C#.
I have written my Website automation code in the specflow. Can I also Reuse it ?

Appium provides the dotnet-appium-driver which is your API to interface with Appium. You can use that to write your app automation.
You did not provide any example here nor code, so I cannot really act on something to show you. I will just write down some C# code to let you understand how a simple test in C# can be written:
namespace AppiumTests
{
using System;
// .NET unit test namespaces needed here as well, just not mentioning them
using OpenQA.Selenium; /* Appium is based on Selenium, we need to include it */
using OpenQA.Selenium.Appium; /* This is Appium */
[TestClass]
public class TestSuite
{
private AppiumDriver driver;
private static Uri testServerAddress = new Uri("http:127.0.01:4723/wd/hub"); // If Appium is running locally
private static TimeSpan INIT_TIMEOUT_SEC = TimeSpan.FromSeconds(180); /* Change this to a more reasonable value */
private static TimeSpan IMPLICIT_TIMEOUT_SEC = TimeSpan.FromSeconds(10); /* Change this to a more reasonable value */
[TestInitialize]
public void BeforeAll()
{
DesiredCapabilities testCapabilities = new DesiredCapabilities();
testCapabilities.App = "<your-app-file>";
testCapabilities.AutoWebView = true;
testCapabilities.AutomationName = "";
testCapabilities.BrowserName = String.Empty; // Leave empty otherwise you test on browsers
testCapabilities.DeviceName = "Needed if testing on IOS on a specific device. This will be the UDID";
testCapabilities.FwkVersion = "1.0"; // Not really needed
testCapabilities.Platform = TestCapabilities.DevicePlatform.Android; // Or IOS
testCapabilities.PlatformVersion = String.Empty; // Not really needed
driver = new AppiumDriver(testServerAddress, capabilities, INIT_TIMEOUT_SEC);
driver.Manage().Timeouts().ImplicitlyWait(IMPLICIT_TIMEOUT_SEC);
}
[TestCleanup]
public void AfterAll()
{
driver.Quit(); // Always quit, if you don't, next test session will fail
}
///
/// Just a simple test to heck out Appium environment.
///
[TestMethod]
public void CheckTestEnvironment()
{
var context = driver.GetContext();
Assert.IsNotNull(context);
}
}
}
You can find more in this article I wrote.

Finally reached to the solution run a test in C#. Many Thanks to Andry.
This solution runs the website in the chrome browser of your phone connected to the computer :

1) Set up usual project in C# , install Appium , Selenium using NuGet package manager , Also install Nunit with the same process.
2) Download Android SDK
3) Envrionment variables : Add variable name "ANDROID_HOME" and in variable give path to sdk folder , In PATH (found in System variable) , append path to tools in sdk folder and append path to platform tools.
4) Connect your device (a.mobile device's drivers should be installed in the computer (my case moto g adb drivers installed) b. device should have developer mode option ON and debugger option checked and always awake option checked)
5) Now download Appium and open the Appium.exe.
6) Appium window -> In Android setting (first button) , check on "Use Browser" option and select "Browser" as an option.
7) Start the appium node server (play button at the top).
8) now run the test from the visual studio and you will see website opening in the browser of phone.

To make this more comprehensive, I have written a blog post which explains all the steps clearly with images. Its a step by step tutorial to use appium with c# and MSTest
You can read it here.
http://www.binaryclips.com/2016/03/test-automation-on-android-using-appium.html

This is how I have implemented Appium. I think it adds some depth to the discussion.
Appium is both a WebDriver that can interact with a device in your project as well as a Server that bridges your project to your physical device or emulator.
You have to run the Appium server as a listener and set up your Capabilities to connect to it. That will start the app and execute your test.
There is a lot more to it than this but here is a setup that you can try to get you on your way:
In a WebDriver Support Class use the [BeforeScenario] tag to execute this code before your test. This has a Sauce Labs implementation.
[BeforeScenario]
public void BeforeScenario()
{
var name = Locale == "sauce" ? "AppiumSauceDriver" : "AppiumDriver";
InitializeServiceLocator();
if (WebDriver == null)
{
InitializeWebDriver(name);
}
ObjectContainer.RegisterInstanceAs(WebDriver);
if (WebDriver != null)
{
Console.WriteLine("Driver Already Exists");
}
}
Then you need to populate the InitializeServiceLocator() method. There is a Device Selector Method here that doesn't do anything other than set the name. You can just hard code it to your capabilities instead.
private static void InitializeServiceLocator()
{
if (ServiceLocator == null)
{
var ip = "";
var deviceType = TestSetupHelper.DeviceSelector["iphone7"];
var capabilities = TestSetupHelper.SetAppiumCababilities(deviceType, Locale);
string server = MSTestContextSupport.GetRunParameter("appiumServer");
var port = Convert.ToInt32(MSTestContextSupport.GetRunParameter("appiumPort"));
if (Locale != "sauce")
{
ip = TestSetupHelper.GetComputerIpAddress(server, port, true);
}
var kernel = new StandardKernel();
kernel.Bind<IOSDriver<AppiumWebElement>>().ToConstructor(x => new IOSDriver<AppiumWebElement>(new Uri("http://" + ip + ":" + port + "/wd/hub"), capabilities, TimeSpan.FromMinutes(10))).Named("AppiumDriver");
kernel.Bind<IOSDriver<AppiumWebElement>>().ToConstructor(x => new IOSDriver<AppiumWebElement>(new Uri("http://ondemand.saucelabs.com:80/wd/hub"), capabilities, TimeSpan.FromMinutes(10))).Named("AppiumSauceDriver");
ServiceLocator = new NinjectServiceLocator(kernel);
Microsoft.Practices.ServiceLocation.ServiceLocator.SetLocatorProvider(() => ServiceLocator);
}
}
From here you need to set up your capabilities. The below method is how I have done it.
public static DesiredCapabilities SetAppiumCababilities(string deviceType, string locale, bool realDevice = false, string udid = "FAKEUDIDFOREXAMPLE")
{
string appiumAppFilePath = MSTestContextSupport.GetRunParameter("appiumAppFilePath");
//Universal Capabilities
capabilities.SetCapability("platformName", "iOS");
capabilities.SetCapability("deviceName", deviceType);
capabilities.SetCapability("automationName", "XCUITest");
capabilities.SetCapability("app", appiumAppFilePath);
capabilities.SetCapability("xcodeOrgId", "GET_THIS_FROM_APP_DEV");
capabilities.SetCapability("xcodeSigningId", "iPhone Developer");
capabilities.SetCapability("noReset", true);
capabilities.SetCapability("newCommandTimeout", 80);
if (locale == "sauce")//Sauce specific capabilities
{
capabilities.SetCapability("appiumVersion", "1.7.2");
capabilities.SetCapability("name", MSTestContextSupport.GetRunParameter("appiumJobName"));
capabilities.SetCapability("username", MSTestContextSupport.GetRunParameter("sauceId"));
capabilities.SetCapability("accessKey", MSTestContextSupport.GetRunParameter("sauceKey"));
capabilities.SetCapability("tunnel-identifier", MSTestContextSupport.GetRunParameter("sauceTunnel"));
capabilities.SetCapability("browserName", "");
capabilities.SetCapability("platformVersion", "11.2");
}
else//Local specific capabilities
{
capabilities.SetCapability("platformVersion", "11.3");
}
if (realDevice)//Sauce real device testing will not need this. This is for Local Real Device testing only
{
capabilities.SetCapability("udid", udid);
}
return capabilities;
}
Anything referencing GetRunParameter is getting a value from a .runsettings file.
Example:
<TestRunParameters>
<Parameter name="appiumJobName" value="OBI App Automated Test"/>
</TestRunParameters>
You have to add all of the stuff to the .runsettings file you are using to run the project that you want to source from there. You can hardcode it if you don't want to go through the runsettings file but I prefer to do it that way. You can make things variable that way based on the runsettings file you have selected.
Then you have to define TestSetupHelper.GetComputerIpAddress(server, port, true); If you have a hard coded IP Address to the computer that is running your Appium server you can just hard code that. Otherwise you need a Helper class somewhere (In this example it is TestSetupHelper). This example initiates a Socket Connection to the server and returns all of the details. That way you don't have to worry about IP addresses changing. You just pass the host name and the port you have Appium configured to run on and you can get the connection information from that connection and make your actual connection to the Appium Server instance.
public static string GetComputerIpAddress(string computerName, int port, bool remote)
{
var ip = "";
using (Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, 0))
{
socket.Connect(computerName, port);
//If remote it gets the connection destination IP, else it gets the connection initiator IP
IPEndPoint endPoint = remote ? socket.RemoteEndPoint as IPEndPoint : socket.LocalEndPoint as IPEndPoint;
ip = endPoint.Address.ToString();
}
return ip;
}
This isn't going to get you completely there but it will get you close to a working environment. Then you can start working on getting a test to actually run.
I hope this helps.

How do I use Selenium in C#?

Selenium.
I downloaded the C# client drivers and the IDE. I managed to record some tests and successfully ran them from the IDE. But now I want to do that using C#. I added all relevant DLL files (Firefox) to the project, but I don't have the Selenium class. Some Hello, World! would be nice.

From the Selenium Documentation:
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium;
class GoogleSuggest
{
static void Main(string[] args)
{
IWebDriver driver = new FirefoxDriver();
//Notice navigation is slightly different than the Java version
//This is because 'get' is a keyword in C#
driver.Navigate().GoToUrl("http://www.google.com/");
IWebElement query = driver.FindElement(By.Name("q"));
query.SendKeys("Cheese");
System.Console.WriteLine("Page title is: " + driver.Title);
driver.Quit();
}
}

Install the NuGet packet manager
Download link: https://visualstudiogallery.msdn.microsoft.com/27077b70-9dad-4c64-adcf-c7cf6bc9970c
Create a C# console application
Right-click on the project → Manage NuGet Packages.
Search for "Selenium" and install package Selenium.Support.
You are done now, and you are ready to write your code :)
For code with Internet Explorer, download the Internet Explorer driver.
Link: http://selenium-release.storage.googleapis.com/index.html
Open 2.45 as its the latest release
Download IEDriverServer_x64_2.45.0.zip or IEDriverServer_Win32_2.45.0.zip
Extract and simply paste the .exe file at any location, for example C:\
Remember the path for further use.
Overall reference link: Selenium 2.0 WebDriver with Visual Studio, C#, & IE – Getting Started
My sample code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;
using OpenQA.Selenium.IE;
namespace Selenium_HelloWorld
{
class Program
{
static void Main(string[] args)
{
IWebDriver driver = new InternetExplorerDriver("C:\\");
driver.Navigate().GoToUrl("http://108.178.174.137");
driver.Manage().Window.Maximize();
driver.FindElement(By.Id("inputName")).SendKeys("apatra");
driver.FindElement(By.Id("inputPassword")).SendKeys("asd");
driver.FindElement(By.Name("DoLogin")).Click();
string output = driver.FindElement( By.XPath(".//*[#id='tab-general']/div/div[2]/div[1]/div[2]/div/strong")).Text;
if (output != null )
{
Console.WriteLine("Test Passed :) ");
}
else
{
Console.WriteLine("Test Failed");
}
}
}
}

To set up the IDE for Selenium in conjunction with C# is to use Visual Studio Express. And you can use NUnit as the testing framework. The below links provide you more details. It seems you have set up what is explained in the first link. So check the second link for more details on how to create a basic script.
How to setup C#, NUnit and Selenium client drivers on Visual Studio Express for Automated tests
Creating a basic Selenium web driver test case using NUnit and C#
Sample code from the above blog post:
using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
// Step a
using OpenQA.Selenium;
using OpenQA.Selenium.Support;
using OpenQA.Selenium.Firefox;
using NUnit.Framework;
namespace NUnitSelenium
{
[TestFixture]
public class UnitTest1
{
[SetUp]
public void SetupTest()
{
}
[Test]
public void Test_OpeningHomePage()
{
// Step b - Initiating webdriver
IWebDriver driver = new FirefoxDriver();
// Step c: Making driver to navigate
driver.Navigate().GoToUrl("http://docs.seleniumhq.org/");
// Step d
IWebElement myLink = driver.FindElement(By.LinkText("Download"));
myLink.Click();
// Step e
driver.Quit();
)
}
}

One of the things that I had a hard time finding was how to use PageFactory in C#. Especially for multiple IWebElements. If you wish to use PageFactory, here are a few examples. Source: PageFactory.cs
To declare an HTML WebElement, use this inside the class file.
private const string _ID ="CommonIdinHTML";
[FindsBy(How = How.Id, Using = _ID)]
private IList<IWebElement> _MultipleResultsByID;
private const string _ID2 ="IdOfElement";
[FindsBy(How = How.Id, Using = _ID2)]
private IWebElement _ResultById;
Don't forget to instantiate the page object elements inside the constructor.
public MyClass(){
PageFactory.InitElements(driver, this);
}
Now you can access that element in any of your files or methods. Also, we can take relative paths from those elements if we ever wish to. I prefer pagefactory because:
I don't ever need to call the driver directly using driver.FindElement(By.Id("id"))
The objects are lazy initialized
I use this to write my own wait-for-elements methods, WebElements wrappers to access only what I need to expose to the test scripts, and helps keeps things clean.
This makes life a lot easier if you have dynamic (autogerated) webelements like lists of data. You simply create a wrapper that will take the IWebElements and add methods to find the element you are looking for.

FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(#"D:\DownloadeSampleCode\WordpressAutomation\WordpressAutomation\Selenium", "geckodriver.exe");
service.Port = 64444;
service.FirefoxBinaryPath = #"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";
Instance = new FirefoxDriver(service);

C#
First of all, download Selenium IDE for Firefox from the Selenium IDE.
Use and play around with it, test a scenario, record the steps, and then export it as a C# or Java project as per your requirement.
The code file contains code something like:
using System;
using System.IO;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
// Add this name space to access WebDriverWait
using OpenQA.Selenium.Support.UI;
namespace MyTest
{
[TestClass]
public class MyTest
{
public static IWebDriver Driver = null;
// Use TestInitialize to run code before running each test
[TestInitialize()]
public void MyTestInitialize()
{
try
{
string path = Path.GetFullPath(""); // Copy the Chrome driver to the debug
// folder in the bin or set path accordingly
Driver = new ChromeDriver(path);
}
catch (Exception ex)
{
string error = ex.Message;
}
}
// Use TestCleanup to run code after each test has run
[TestCleanup()]
public void MyCleanup()
{
Driver.Quit();
}
[TestMethod]
public void MyTestMethod()
{
try
{
string url = "http://www.google.com";
Driver.Navigate().GoToUrl(url);
IWait<IWebDriver> wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(30.00)); // Wait in Selenium
wait.Until(ExpectedConditions.PresenceOfAllElementsLocatedBy(By.XPath(#"//*[#id='lst - ib']")));
var txtBox = Driver.FindElement(By.XPath(#"//*[#id='lst - ib']"));
txtBox.SendKeys("Google Office");
var btnSearch = Driver.FindElement(By.XPath("//*[#id='tsf']/div[2]/div[3]/center/input[1]"));
btnSearch.Click();
System.Threading.Thread.Sleep(5000);
}
catch (Exception ex)
{
string error = ex.Message;
}
}
}
}
You need to get the Chrome driver from here.
You need to get NuGet packages and necessary DLL files for the Selenium NuGet website.
You need to understand the basics of Selenium from the Selenium documentation website.
That's all...

driver.FindElement(By.ClassName("account_icon")).Click();
driver.FindElement(By.LinkText("Log out")).Click();
driver.Close();
}
}

You will need to install Microsoft Visual Studio community Edition
Create a new project as Test Project of C#
Add Selenium references from the NuGet Package Manager. Then you will be all set.
Create a new class and use [Test Class] and [Test Method] annotations to run your script
You can refer to Run Selenium C# | Setup Selenium and C# | Configure Selenium C# for more details.

Use the below code once you've added all the required C# libraries to the project in the references.
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
namespace SeleniumWithCsharp
{
class Test
{
public IWebDriver driver;
public void openGoogle()
{
// creating Browser Instance
driver = new FirefoxDriver();
//Maximizing the Browser
driver.Manage().Window.Maximize();
// Opening the URL
driver.Navigate().GoToUrl("http://google.com");
driver.FindElement(By.Id("lst-ib")).SendKeys("Hello World");
driver.FindElement(By.Name("btnG")).Click();
}
static void Main()
{
Test test = new Test();
test.openGoogle();
}
}
}
