It is useful when you have unit tests, integration tests, functional tests in the same test project but under different namespaces such as
/NUnitTests.UnitTests
/NUnitTests.IntegrationTests
/UnitTestss.FunctionalTets

1. Open up CMD.exe and CD to C:\Program Files (x86)\NUnit 2.5.10\bin\net-2.0

2. Input:
nunit-console Path_To_NUnitTests.dll /run=NUnitTests.UnitTests,NUnitTests.IntegrationTests
Or
nunit-console Path_To_NUnitTests.dll /run:NUnitTests.UnitTests,NUnitTests.IntegrationTests

The only thing you need to be careful here is that do not leave space between the namespaces!

The answer from the stackoverflow question is very useful.

PetaPoco seems to be a very nice little micro ORM framework, I have given a try to create some demo for it. It seems to be relatively easy to use besides the T4 template may not be that straightforward if you have not never used it before.

1. Install the latest Nuget
Get it from http://nuget.org/ and install it to your VS2008/2010

2. Install the PetaPoco package via Nuget

Right click the Project root in the Visual Studio

Search for PetaPoco package

After installed the package, it will generate a few files under the /Models folder

3. Add the connection string in the web.config, in my case, it is a connection string to the MS Northwind database.

<add name="NorthwindConnection" connectionString="data source=.;Initial Catalog=Northwind;Integrated Security=SSPI;" providerName="System.Data.SqlClient" />

4. Add ConnectionStringName = “NorthwindConnection“; to the Database.tt T4 template file
under /Models/Generated folder, and save the change, the T4 generator will generate all of the database Poco classes
in the Database.cs file.

5. Add a CustomerController, Customer Index view and CustomerModels for demonstrating the PetaPoco magic.

    Model:

    public class CustomerModel
    {
        public IEnumerable<Customer> GetCustomers()
        {
            var db = new PetaPoco.Database("NorthwindConnection");
            return db.Query<Customer>("SELECT * FROM Customers");
        }
    }

   View Action:

   public ActionResult Index()
   {
       var cm = new CustomerModel();
       ViewBag.Customers = cm.GetCustomers();
       return View();
   }

   Razor View:

   @model NorthwindConnection.Customer

   @{
      ViewBag.Title = "Customer";
    }

   <h2>Customer List</h2>
   <table>
    @foreach (var c in ViewBag.Customers)
    {
        <tr>
            <td>@c.CustomerID</td>
            <td>@c.CompanyName</td>
            <td>@c.ContactName</td>
            <td>@c.Phone</td>
        </tr>
    }
   </table>

Note:
You can install PetaPoco from the Nuget, if you have encountered error when installing via Nuget “The ‘schemaVersion’ attribute is not declared.” It probably means you have an old version of Nuget, visit http://nuget.org/ and install the latest version.

Entity Framework Profiler

The Selenium2 WebDriver has some exciting features compared to Selenium 1. You can find more details on the Selenium offical blog release blog about Selenium2!

1. New WebDriver APIs for Python, Ruby, Java and C#, PHP, Perl, WebkitDriver.
2. Fast (no need to run RC server anymore), stable and a lot of bug fixes.
3. IE(6-9)/Firefox(3,4,5,6,7)/Chrome/Opera support
More…

You can download the dotnet webdriver API from:

http://code.google.com/p/selenium/downloads/list

If you are using InternetExploreDriver, you need to modify some security settings, which you can find out more from this wiki page.

On IE 7 or higher on Windows Vista or Windows 7, you must set the Protected Mode settings for each zone to be the same value. The value can be on or off, as long as it is the same for every zone. To set the Protected Mode settings, choose “Internet Options…” from the Tools menu, and click on the Security tab. For each zone, there will be a check box at the bottom of the tab labeled “Enable Protected Mode”.
The browser zoom level must be set to 100% so that the native mouse events can be set to the correct coordinates.

I have created a really basic C# library project when playing with selenium2 webdriver, you can download it from: Selenium2Sample

For migrating from Selenium1 to Selenium2, you can take a look at:

http://seleniumhq.org/docs/appendix_migrating_from_rc_to_webdriver.html#migrating-to-webdriver-reference

There are some links below that I found quite helpful along the way.

@ symbol is quite handy in csharp when you want to paste a file path or multiple lines of sql queries etc. Such as

string path = @”c:\temp\hello.txt”;
string path2 = “c:\\temp\\hello.txt”;

The above two lines of code produce the same result, which is the same as path2.

Now let’s see an example for multiple lines of string concatenation.

static void Main(string[] args)
{
    StringsCompare();
}

private static void StringsCompare()
{
  string a = @"SELECT * FROM TABLE
WHERE 1 = 1";
  string b = "SELECT * FROM TABLE\\r\\n" + "WHERE 1 = 1";
  Console.WriteLine("a: \\r\\n" + a);
  Console.WriteLine("b: \\r\\n" + b);
  Console.WriteLine();
  Console.WriteLine(a == b);
}

The @ symbol is a complier feature which result the same constant string as using + sign to concatenate strings together.
Following is the result of the decompiling the above code using the ILSpy:

private static void StringsCompare()
{
  string a = "SELECT * FROM TABLE\\r\\nWHERE 1 = 1";
  string b = "SELECT * FROM TABLE\\r\\nWHERE 1 = 1";
  Console.WriteLine("a: \\r\\n" + a);
  Console.WriteLine("b: \\r\\n" + b);
  Console.WriteLine();
  Console.WriteLine(a == b);
}

pres ctrl+alt+t to open terminal and then:
1. sudo apt-get install ruby1.9.2-full
2. sudo gem install rails –no-ri –no-rdoc
(file not found ‘lib’ issue)

restart the terminal after installing and check
ruby -v
rails -v

Output:
1.9.2p290
Rails 3.1.0

1. You now can use the windows build for nodejs, Windows Executable: http://nodejs.org/dist/v0.5.6/node.exe
Download it and copy the sample js code from the nodejs.org

var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, "127.0.0.1");
console.log('Server running at http://127.0.0.1:1337/');

Save as test.js then in cmd.exe, type: node test.js then you will get the following output.

Server running at http://127.0.0.1:1337/

Open http://127.0.0.1:1337/ in your browser then you will see ‘Hello World’ on the page.

2. Also you can also try the CoffeeScript compiler for Windows as well.
Go to https://github.com/alisey/CoffeeScript-Compiler-for-Windows, download the coffee.exe, and set the coffee.exe folder path to the environment PATH variable and you are good to go!

It is always easy once you figure it out.

typeperf “\Process([process name])\*” to monitor a particular process in your system. For instance, typeperf “\Process(cmd)\*” or typeperf “\Process(cmd)\Working Set” or typeperf “\Process(cmd)\% Processor Time” etc, but it is not really readable unless you only need to see some particular counter like Working Set. Otherwise you should use perfmon.exe GUI tool for more complicated scenario like scheduled performance data collection and adding more counters etc.
