Develop Reference

I am trying to run a test on multiple Browsers using MSTest and Selenium

I am simultaneously teaching myself Selenium 3.0 and Programming to learn how to Automate my tests (previously a manual tester with no IT background, fell into testing via UAT).
I have successfully written a handful of tests all of which work :). I can define which browser to run the test set on, but cant run the test set on multiple browsers as 1 test run. (I have to define the browser in my Test Initialise and comment out the other browsers). When I try to run the test on 2 browsers at once Browser A opens but nothing runs, Browser B then opens and runs the tests.
I have looked through the posts on this site and on google generally but have not found a clear answer to how to get this to work using MSTest and Semenium in C#
My Code
One of my tests
using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Kukd_Consumer_Tests;
namespace Kukd_Consumer_Test
{
//login from Hompage
[TestClass]
public class Login : Consumer_Standard_Functionality
{
[TestMethod]
public void User_Can_Login()
{
LoginPage.LoginAs("Richard.Cariven#Kukd.Com").WithPassword("Test1234").Login();
Assert.IsTrue(AccountPageAssert.IsAtAccountPage("Hi Richard"), "Failed to login");
}
}
}
My std Functionality Test Class (Initialise and Cleanup steps)
using Kukd_Consumer_Tests;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Kukd_Consumer_Test
{
public class Consumer_Standard_Functionality
{
[TestInitialize]
public void Init()
{
driver.InitializeChrome();
driver.InitializeFireFox();
Homepage.GoTo_HomePage();
}
[TestCleanup]
public void Cleanup()
{
driver.Quit();
}
}
}
My driver class
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.Remote;
using System;
namespace Kukd_Consumer_Tests
{
public class driver
{
public static IWebDriver Instance { get; set; }
public static void InitializeChrome()
{
Instance = new ChromeDriver(#"C:\Users\xxxxxxxxx.xxxxxxxx\Documents\Visual Studio 2015\Drivers\Chrome");
Instance.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10));
}
public static void InitializeFireFox()
{
Instance = new FirefoxDriver();
Instance.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10));
public static void Quit()
{
Instance.Quit();
}
}
}
My LoginPage class
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Kukd_Consumer_Tests
{
public class LoginPage
{
public static LoginCommand LoginAs(string userName)
{
return new LoginCommand(userName);
}
public class LoginCommand
{
private readonly string userName;
private string password;
public LoginCommand(string userName)
{
this.userName = userName;
}
public LoginCommand WithPassword(string password)
{
this.password = password;
return this;
}
public void Login()
{
var accountButton = driver.Instance.FindElement(By.LinkText("My Account"));
accountButton.Click();
var loginInput = driver.Instance.FindElement(By.Id("login-email"));
loginInput.SendKeys(userName);
var passwordInput = driver.Instance.FindElement(By.Id("login-password"));
passwordInput.SendKeys(password);
var loginButton = driver.Instance.FindElement(By.Id("loginBtn"));
loginButton.Click();
}
}
}
}
When I run the above Chrome opens a blank window and does nothing more. Firefox opens the homepage, then runs the test as expected and closes the window when done.

COM object that has been separated from its underlying RCW cannot be used while testing

I'm doing some test using the .NET 4.5 TestTools and Visual Studio 2010. I m testing a singleton class that creates an COM Instance somewhere during construction/initialization, so the classes state will be keep the same in all tests. The Problem is, each test runs for itself, running all test will give a strange result - the first test succeeds, all other fail
"System.Runtime.InteropServices.InvalidComObjectException: COM object
that has been separated from its underlying RCW cannot be used.."
result of a corrupted COM reference (see myComInstance below).
Not quite sure if i explained the problem correctly. Below is my singleton class
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace APITestTrial3
{
public partial class frmMbxControl : Form
{
private frmMbxControl()
{
InitializeComponent();
Connect("abhishek281mbx","PCMBXsrv.281","appmat1.bsd.com");
}
private static frmMbxControl g_Mbx;
public static frmMbxControl GetMbx()
{
if (g_Mbx == null)
{
g_Mbx = new frmMbxControl();
}
return g_Mbx;
}
private string Connect(string mbxName, string serverName, string hostName)
{
// frmControls frm = new frmControls();
mbx.HostName = hostName;
mbx.MbxName = mbxName;
mbx.ServerName = serverName;
mbx.replybox = "replyBox";
if (mbx.Status != 0)
{
if (mbx.Connect())
{
Console.WriteLine("Connected");
return ("Connected");
}
else
{
return ("Not Connected");
}
}
return ("Connected");
}
public String Send(String txnName, String txn)
{
String msgReply = "";
String rep = "";
//mbx.Send(txnName, txn);
mbx.Open("ReplyBox1","c");
mbx.SendAndReply(txnName, txn, "ReplyBox1");
if (mbx.WaitForMsg("ReplyBox1", 0, ref msgReply, ref rep) == CwMboxLib.CwWaitResult.CwWaitOk)
{
rep = msgReply;
mbx.Close("ReplyBox1");
}
return msgReply;
}
private void frmMbxControl_Load(object sender, EventArgs e)
{
}
}
}
Another class uses GetMbx() and Send() method of above class.

NSubstitute Checking received calls don't work

Hey guys im new with the NSubstitute framework. I'm trying to test some of my classes, but when i use NSubstitute to check received calls it says received no matching calls.
I'm trying to test if the method Tick() is receiving update() from track class.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ATM_System.Event;
using ATM_System.EventDetection;
using ATM_System.Region;
using ATM_System.Track;
namespace ATM_System
{
public class ATM
{
private List<ITrack> _tracks;
private IRegion _region;
private List<IEventDetection> _eventdetects;
private List<IEvent> _events;
public ATM()
{
_tracks = new List<ITrack>();
_region = new Region.Region(100000,100000); //could be changed by user
_events = new List<IEvent>();
_eventdetects = new List<IEventDetection>();
}
public void Tick()
{
// update track positions
foreach (var track1 in _tracks)
{
track1.update();
}
//check for events
foreach (var detector in _eventdetects)
{
_events.AddRange(detector.DetectEvent(_tracks));
}
//handle events and output
foreach (var event1 in _events)
{
event1.HandleEvent();
event1.LogEvent();
}
}
public void IncomingTrack(ITrack track)
{
//add incoming track
_tracks.Add(track);
}
}
}
TEST FILE
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ATM_System.Event;
using ATM_System.EventDetection;
using ATM_System.Track;
using NUnit.Framework;
using NSubstitute;
namespace ATM_System.Tests.Unit
{
[TestFixture]
class ATMUnitTests
{
private ATM _uut;
private ITrack _track;
private IEvent _event;
private IEventDetection _eventDetection;
[SetUp]
public void Setup()
{
_track = Substitute.For<ITrack>();
_event = Substitute.For<IEvent>();
_eventDetection = Substitute.For<IEventDetection>();
_uut = new ATM();
}
[Test]
public void Tick_UpdateTracks_TracksUpdated()
{
_uut.Tick();
_track.Received().update();
}
}
}

You forgot to include _track in notification receivers. It simply hasn't subscribed to event and as a result is not notified. To fix simply call your IncomingTrack method:
[Test]
public void Tick_UpdateTracks_TracksUpdated()
{
_uut.IncomingTrack(_track);
_uut.Tick();
_track.Received().update();
}

Dynamic parameters in postsharp

I am trying to assign the property dynamically using post sharp. Such as in the below example I would like to have custom logging messages. But the problem is how could I set xname in the attribute part.In the first log I would like to have the logging message would have the persons name in the beginning but the second logging message would have the persons name at the end.
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplicationLogging
{
internal static class Program
{
private static void Main()
{
Trace.Listeners.Add(new TextWriterTraceListener(Console.Out));
SayHelloInTurkish("Ayse");
SayGoodByeSayHelloInEnglish("Elizabeth");
}
[Trace("xname Loglanıyor Gunaydın")]
private static void SayHelloInTurkish(string personName)
{
Console.WriteLine("Hello, world.");
}
[Trace("Good Bye Logging for xname")]
private static void SayGoodByeSayHelloInEnglish(string personName)
{
Console.WriteLine("Good bye, world.");
}
}
}
using System;
using System.Diagnostics;
using PostSharp.Aspects;
namespace ConsoleApplicationLogging
{
[Serializable]
public sealed class TraceAttribute : OnMethodBoundaryAspect
{
private readonly string category;
public TraceAttribute(string category)
{
this.category = category;
}
public string Category { get { return category; } }
public override void OnEntry(MethodExecutionArgs args)
{
if (args.Method.DeclaringType != null)
Trace.WriteLine(string.Format("Entering {0}.{1}.",
args.Method.DeclaringType.Name, args.Method.Name), this.category);
}
public override void OnExit(MethodExecutionArgs args)
{
if (args.Method.DeclaringType != null)
Trace.WriteLine(string.Format("Leaving {0}.{1}.",
args.Method.DeclaringType.Name, args.Method.Name), this.category);
}
}
}

If I understand correctly, you need something like this (no sanity checking included):
this.category.Replace("xname", (string)args.Arguments[0])
If I did not understand correctly, feel free to comment below.

wiimotelib bug?

I am recently writing a wiimote program:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using WiimoteLib;
namespace WiiTester
{
public partial class Form1 : Form
{
Wiimote wm = new Wiimote();
public Form1()
{
InitializeComponent();
wm.WiimoteChanged += wm_WiimoteChanged;
wm.WiimoteExtensionChanged += wm_WiimoteExtensionChanged;
wm.Connect();
wm.SetReportType(InputReport.IRAccel, true);
}
void wm_WiimoteChanged(object sender, WiimoteChangedEventArgs args)
{
WiimoteState ws = args.WiimoteState;
if (ws.ButtonState.A == true)
{
wm.SetRumble(true);
}
else
{
wm.SetRumble(false);
}
}
void wm_WiimoteExtensionChanged(object sender, WiimoteExtensionChangedEventArgs args)
{
if (args.Inserted)
{
wm.SetReportType(InputReport.IRExtensionAccel, true);
}
else
{
wm.SetReportType(InputReport.IRAccel, true);
}
}
}
}
My wiimote keeps getting disconnected and this error keeps running on wm.Connect();
Timed out waiting for status report
Is there a solution?

I have a lot of experience with this library, and your problem is most likely being caused because you are calling SetRumble so often, this code:
void wm_WiimoteChanged(object sender, WiimoteChangedEventArgs args)
{
WiimoteState ws = args.WiimoteState;
if (ws.ButtonState.A == true)
{
wm.SetRumble(true);
}
else
{
wm.SetRumble(false);
}
}
Will call SetRumble constantly whether A is down or not, consider using this code instead:
bool rumbleOn = false;
void wm_WiimoteChanged(object sender, WiimoteChangedEventArgs args)
{
WiimoteState ws = args.WiimoteState;
bool newRumble = (ws.ButtonState.A == true);
if (rumbleOn != newRumble)
{
rumbleOn = newRumble;
wm.SetRumble(rumbleOn);
}
}
This way the set rumble method is only called when required and not constantly sending output reports to the WiiMote which causes the Bluetooth BUS to overload.
