Let's customize Google to show previous searchs by Hitesh Sharma

2012-01-24T18:38:00.001+05:30

while going through code project website i show one article published by Hitesh sharma.
which catches my eyes with his nice idea and explanation of the article.
awesome!!
here is little introduction:
Introduction

Usually when I Google something there are a good amount of chances that I'll be googling the same thing again after a few days to recollect whatever I learned last time. So I run Internet Explorer and look into the history if I feel like hitting the search button again with the same keywords as I used last time to get the results I am looking for. This works great but one day I just wondered that why doesn't google shows recently searched text on its page, if it does so it will provide Googlers much ease. Certainly since I can't approach Google with the idea so I decided to customize google for my machine so that it may show me whatever I looked for last few times

you can visit this link to get the more details about the artile.

Google Automation-Automated Testing Search Engine

2012-01-22T13:05:00.001+05:30

While I was reading Sep 2011 issue of Automated Software Testing Magazine, but at one page my eye got stuck, where the publisher has partnered with Google to create a software test automation search engine. I tried this and its work great it means gave my all search related to automation.

So here is the word complied for the same magazine.

“The Automated Testing Institute has partnered with Google to create a software test automation search engine. If your are looking for the software test automation information, you will get the best results by using this search engine, because it only searches the sites that matter most to automators. You can also restrict searches to blogs and forum sites."

Script to Get Microsoft Product Installed on your machine with version Number

2012-01-16T15:02:00.001+05:30

Few days back I was working on build machine. Or you can say I need to release new build machine installed with some specific software.

To achieve this I wrote few bat file to installed particular software silently.

But to verify this whether that software or application has been installed or not I need to check this through control panel. It was kind of manual process.

So avoid this manual process I came across bat file or VBscript file which will list out the entire Microsoft product with version number installed on that particular machine.

First I will show you the bat file to write the entire product with version list in test file:

echo CompanyName SoftwareInstalled VersionNumber>ListOfMicroSoftware.txt

echo ===========================================>>ListOfMicroSoftware.txt
cscript //nologo D:\Install-Jawed\GetListOfSoft.vbs >>ListOfMicroSoftware.txt

Now here is the logic written in VBscript file.

On Error Resume Next

Const strComputer = "."
Const HKLM = &H80000002
Const strKeyPath = "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
Dim oReg, arrSubKeys, strProduct, strDisplayName, strVersion
Set oReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _
strComputer & "\root\default:StdRegProv")
' Enumerate the subkeys of the Uninstall key
oReg.EnumKey HKLM, strKeyPath, arrSubKeys
For Each strProduct In arrSubKeys
' Get the product's display name
oReg.GetStringValue HKLM, strKeyPath & "\" & strProduct, "DisplayName", strDisplayName
' Process only products whose name contain 'Microsoft'
If InStr(1, strDisplayName, "Microsoft", vbTextCompare) > 0 Then
' Get the product's display version
oReg.GetStringValue HKLM, strKeyPath & "\" & strProduct, "DisplayVersion", strVersion
WScript.Echo strDisplayName &"======"& vbTab &"===========================================" & strVersion
End If
Next

Click on bat file and it will generate the text file with all products with version number.

Enable Sound when Breakpoint is hit in Visual Studio 2010

2012-01-12T12:10:00.000+05:30

It is really interesting and funny to let Visual studio make sound or give some signal that it hit break point.

So here is the tips to do the same. I have done this in windows 7 machine. Might be for other OS setting would be different.

First look at the below snap shot.

Steps:
1. Go to Control Panel.
2. Click on Hardware and Sound. A different window appears.
3. On new popup window click on Change System sounds. A different pop window would appear, refer above snap shot.
4. Select sound tab and scroll down to Microsoft Visual Studio.
5. Select Break point Hit.
6. Now select your desired sound from Sounds drop down menu.
7. Click on Apply and then ok.

Now you are ready to hear the Hit sound, whenever visual studio would hit the breakpoint.

Happy Debugging.

Copy files from source directory to target directory using Xcopy in C#.

2012-01-11T13:07:00.002+05:30

If you are interested to copy files and folder to target location using Xcopy then just use the below piece of code to perform you desired operation.

private static void ProcessXcopy(string SolutionDirectory, string TargetDirectory)

{
     // Use ProcessStartInfo class
    ProcessStartInfo startInfo = new ProcessStartInfo();
    startInfo.CreateNoWindow = false;
    startInfo.UseShellExecute = false;
    startInfo.FileName = "xcopy";
    startInfo.WindowStyle = ProcessWindowStyle.Hidden;
    startInfo.Arguments = "\"" + SolutionDirectory + "\"" + " " + "\"" + TargetDirectory + "\"" +
                                                                                                                                      @" /e /y /I";
    try
    {
         using (Process exeProcess = Process.Start(startInfo))
          {
             exeProcess.WaitForExit();
          }

Get Assembly Version

2012-01-11T12:54:00.001+05:30

Below code would help you get the Assembly version.
This code also stamp the build version in a file where you want to write the build version.
The build version is nothing but versioning provided after building the Project from tfs.
so here the code:
///

/// This method will get the version
///
/// return version of version as string
private static string GetVersion()
{
Assembly assembly = Assembly.GetExecutingAssembly();
FileVersionInfo fileVersionInfo = FileVersionInfo.GetVersionInfo(assembly.Location);
return fileVersionInfo.ProductVersion;
}

Dynamically Find controls Type used in web application using WaTin

2011-12-16T15:11:00.000+05:30

Introduction:
Using this WaTin feature user would be able to get all the controls types dynamically used in web page.
Details:

While performing automation so many times we have faced the issues to find the control type on fly and perform some basic operation or get the properties of controls.

Let me give an example to explain this with clear picture.

Suppose that developer has placed a table on webpage. This table would contents many controls like textbox, button, picture box, label, dropdown, list etc. etc. all this control would appear in table cells dynamically, it means we are not sure when and at what position of cells it will appear in table.

Now we have to read this control on fly and performed some basic operation.

So being an automation engineer, we have programmed our automation code in such a way to know about this control and where it has appeared then performed operation or read properties of that control.

Its bit tricky to handle this kind of situation.

To solve this kind of issues WaTin have provided one best feature to get the type of controls and then based on control we can call our custom method to either get the properties or performed common action.

Here I will only show to how to read controls types on FLY using WaTin.

Below is the Image of web page (to automate this scenario I have developed one basic web application)

And here is the piece of the code to the same.

try

{
IE ie = IE.AttachTo<IE>(Find.ByUrl("http://localhost:28348/Home.aspx"));
var tablecells = ie.Table("table").TableCells;
var type = new string[tablecells.Count];
int i = 0;
    foreach (TableCell tableCell in tablecells)
    {
      try
       {
          string watinType = tableCell.Elements[0].GetType().FullName;
          if (watinType != null) type[i] = watinType.Split('.')[2];
       }
       catch (Exception)
       {
           throw;
        }
    i++;
    }
}
Catch (Exception)
{
throw;
}

And below is the Result when you run the above piece of code. You can see all the controls type in the Type array of string. Shown in below drop down.

Feel free to provide your valuable comments and suggestion.

Perform action on web application using White framework

2011-12-14T14:25:00.000+05:30

Introduction:
Using this user would be able to transfer control from WaTiN framework to White Framework to perform action on target web site which is not provided by WaTin.
you can also read this post on http://www.c-sharpcorner.com/UploadFile/jawedmd/perform-action-on-web-application-using-white-framework/

Details:
Before explain this Article/tips I assume that reader is well aware with WaTiN and White Framework (refer below link to get roll your eyes with WaTin and White framework).

Being automation engineering sometimes while automating web application we have to passes the browser control from one framework to another framework to perform some additional action/task on target application.

Okay so let's talk about some real time scenario.

To automate web application I highly concentrated on WaTin framework, as I'm good in that.But sometimes I have to pass browser control from WaTin to White (framework for Windows application) to get focus of open browser or to bring the Browser on User Focus and/or user wants to Click at some particular coordination of browser for that the white framework is much comfortable doing this.

• To know more about White you can refer my link posted on this site
    Click Here
       "or"
http://white.codeplex.com/

• And to know more about WaTin framework you can refer below link.
   http://watin.org/

okay so now come to the coding part,To achieve this below is the piece of code doing the same?.

I have commented each lines of the code to get clear picture about logic of the code written. And I think rest of things is self-explanatory.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using WatiN.Core;
using WatiN.Core.Logging;
using WatiN.Core.Native.Windows;
using White.Core;
using White.Core.UIItems;
///

///Pass the Browser control from Watin to White
///

class BrowserFocus
{
//Instance of Internet explorer using watin
readonly IE _browser = new IE();
///

/// Method to open browser using watin
///

public void AutomationUsingWaTin()
{
//open browser
_browser.GoTo(http://jawedm.blogspot.com);
_browser.WaitForComplete();
//call white method to pass control from watin to white
PerformActionUsingWhite();

}
///

/// Perform Operation on Web application using White, by passing control from WaTin To White
///

private void PerformActionUsingWhite()
{
try
{
//Get the application from watin using processId
var app = White.Core.Application.Attach(_browser.ProcessID);
//get the open browser by watin for white
var windows = app.GetWindows();
White.Core.UIItems.WindowItems.Window window;
//check whether its having browser control or not
if (windows.Count == 1)
{
window = windows[0];
}
else
{//get the browser control using desktop instance
window = White.Core.Desktop.Instance.Windows().Find(w => w.Title.Contains(_browser.Title));
}
//bring the focus on Browser using white
window.Focus();
//Coordination of point where we want to perform right click
var point = new System.Windows.Point(400, 500);
//Right click on the browser using white.
window.RightClickAt(point);
}
catch (Exception ex)
{
// This happens when one of the open windows doea not respond.
// Logger.TraceException("White caused an exception", ex);
}
}
}

Assert for Image in MStest

2011-11-29T11:22:00.001+05:30

Few days back while giving an interview in some R&D company. The interviewer who took my interview asked me one question, how will you assert images in test method and I was unable to answer this question, cuz I had never used this in my automation till now. Let me put this in clear way!!

Question: In your test method how will you assert for image. Like assert that two given images are same or equal?

Answer: I was not having clear answer to this question. Just I told that we have to customize our Assert for images assert.

Then I come back and wrote piece of code to assert the image for AreEqual.

Here is the code. Thanks to interviewer who forced me to think about this.

Test Method:

Assert Class for Image(Assert.AreEqual)

Please feel free to provide your Feedback and comments!!

Tools To Validate Output\Get all dependencies objects From Store Procedure.

2011-10-25T15:30:00.000+05:30

**********TALK 2 DB**************
I have developed an application/tool to get the output from a store procedure after connecting to the source and target storprocedure on a specific server.

Just you need to pass inputs parameter on UI and this will show all the output values generated by selected store procedure. Even you will get flexibility to get all the dependencies object names on particular selected store procedure name. These entire interfaces on UI itself.

Still i am working to come with full article or details.

Soon I will share an article with all of you.

To just give a glimpse of the application, i have added few snaps shot of tool.

"Talk2DB" that’s the name of this tool.

Compare bitmaps images.

2011-10-03T13:25:00.002+05:30

Here is the code to compare 2 bitmaps images.
public class ComparingImages
{
   public enum CompareResult
   {
      Match,
      Mismatch,
      SizeMismatch
   };

public static CompareResult Compare(Bitmap bmp1, Bitmap bmp2)
{
   CompareResult cr = CompareResult.Match;
   //Test to see if we have the same size of image
   if (bmp1.Size != bmp2.Size)
   {
     cr = CompareResult.SizeMismatch;
   }
else
  {
    //Convert each image to a byte array
    ImageConverter ic = new ImageConverter();
   byte[] btImage1 = new byte[1];
   btImage1 = (byte[])ic.ConvertTo(bmp1, btImage1.GetType());
   byte[] btImage2 = new byte[1];
   btImage2 = (byte[])ic.ConvertTo(bmp2, btImage2.GetType());
   //Compute a hash for each image
   var shaM = new SHA256Managed();
   byte[] hash1 = shaM.ComputeHash(btImage1);
   byte[] hash2 = shaM.ComputeHash(btImage2);
   //Compare the hash values
   for (int i = 0; i < hash1.Length && i < hash2.Length
   && cr == CompareResult.Match; i++)
   {
     if (hash1[i] != hash2[i])
     cr = CompareResult.Mismatch;
    }
   }
   return cr;
}
}

Resizing an Array

2011-09-21T14:41:00.000+05:30

I have seen people declaring an array of fixed size. But sometimes while working on dynamic elements size this would be capable enough to hold all the elements in the array. But unfortunately it’s not true. Sometimes you need to handle with small set of data and sometimes with big set of data. Then, how to resize the array. So that it would be capable enough to hold this situation.

Simple:

The .NET Framework Version 2.0 introduced a solution to this problem by adding the

Array.Resize method, which is used to change the size of an array.

Assume that, you have an array named firstArray initialized with five

Elements, you can extend its size to ten elements by using the following

statement:

Array.Resize (ref firstArray, 10);

This is very small method. but, very useful

See the example with the code below.

What ia dumb file and how to capture it.

2011-08-16T10:44:00.000+05:30

A nice article to read about What is a dump, and how do I create one?

i found this while surfing..so thought to share with all of you!!

http://blogs.msdn.com/b/debugger/archive/2009/12/30/what-is-a-dump-and-how-do-i-create-one.aspx

Using Visual studio you can capture the Dump file also.

make sure that under Debuge the Save Dump As menu item is added in visual atudio. if not then follow the below steps to add this menu item:

a. Select Tools -> Customize

b. Select the Commands tab

c. Select Debug from the Menu bar dropdown

d. Click Add Command...

e. Select Debug from the Categories list.

f. Find the Save Dump As entry in the Commands window.

g. Click OK (the Save Dump As... command is added to the top of the Debug menu).

h. Click Close

You can use the following steps to get a mini dump file:

1. Start Visual Studio.

2. Start another instance of VS.

3. In the second instance click Tools
Attach to Process...

4. In the list of processes locate devenv.exe.

5. Click Select... and explicitly choose 'Native' and 'Managed' code.

6. Click OK and OK to close Select dialog and Attach to Process dialog.

7. Go back to the first instance of VS and repro the crash\hang.

8. Upon the crash\hang, control should go to the second instance of VS.

9. In the second instance click Debug
Save Mini Dump (without heap).
