Parameterizing web servers helps in parameterizing URLs of web server in web test. We can use the same web tests for different environments without need to regenerate the code.

Let me show how to parameterize web servers:

• Open the web test
• Click on parameterize web servers button
• 
• Parameterize webservers screen shown
• 
• Click on change
• Enter context parameter name and web server to be used
• 
• Context parameters will be added and URLs will be replaced with the parameter name
• 
• Update the context parameter to required URL

You can use Xperf tool to capture trace and narrow down exact processes/operation which is causing performance issue like CPU usage, disk utilization by process, File I/O Types, processes usage and etc.

Example: To trace disk IO and CPU usage run the following trace command

E:\xperf>Xperf.exe -START -on FileIO+CSWITCH+DISK_IO_INIT+PROFILE+FILENAME+DRIVERS+NETWORKTRACE+DPC+INTERRUPT+Latency -stackwalk CSwitch+DiskReadInit+DiskWriteInit+DiskFlushInit+FileCreate+FileCleanup+FileClose+FileRead+FileWrite+FileFlush+profile -f E:\xperfresults\GSdiskio.etl -BufferSize 1024 -MaxBuffers 1024 -MaxFile 1024 -FileMode Circular

Run the performance scripts.

Stop tracing.

E:\xperf>xperf -stop

GSdiskio.etl is the trace file name open the trace file using xperfview.exe and analyze the results.

CUITe is coded UI test enhanced framework available at https://cuite.codeplex.com/ useful for test UI automation. The advantages of CUITe is reduced code, better readability and maintainability. Let me show how to use CUITe.

• Download and install from https://cuite.codeplex.com/
• Launch CUITe_ObjectRecorder
• Enter website address to test
• 
• Click on record
• Click on the controls in web page
• Click on Code button in the toolbar
• It will generate the code as  shown below

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using Microsoft.VisualStudio.TestTools.UITesting;
  using CUITe.Controls.HtmlControls;

  namespace $ProjectNameSpace.$ObjectRepository
  {
     
         public class LoginWindow : CUITe_BrowserWindow
      {
          public new string sWindowTitle = "Server Login";
          public CUITe_HtmlEdit txtusername = new CUITe_HtmlEdit("Id=username");
          public CUITe_HtmlPassword txtpassword = new CUITe_HtmlPassword("Id=password");
          public CUITe_HtmlInputButton btnLogIn = new CUITe_HtmlInputButton("Value=Log In");

      }
  }

• Create test project.
• Record a normal Coded UI test to get all references done automatically.
• Add reference to “CUITe.dll”  from the install path. Do not copy and reference.
• Create objectrepository folder
• Add a class file and rename it to LoginWindow
• Copy paste the above code in a LoginWindow.cs file which will act as object repository. Update the name space and class name appropriately.
• Can have inheritance work for object repository classes (move common stuff to parent classes for better organization and modularity).
• In test methods you can call the objects as

LoginWindow.txtusername.SetText(username);

LoginWindow.txtpassword .SetText(password);

LoginWindow.btnLogIn .Click();

Note:

1. Object recorder now only works for html/web.

2. Object recorder only records the object/control definitions, not actions.

For one of my application testing I required files of specific different size starting from 1 MB to 1.5 TB. Using fsutil you can easily create a new file of a specific size as shown below:

Syntax:

fsutil file createnew <path with name of file> <size in bytes>

For example the command to create one GB file is:

fsutil file createnew d:\OneGB.txt 1073741824

When using Web performance tests it might not show web test recorder in Internet explorer (IE) meaning the web test recorder add-on is disabled. If web test recorder is not visible in IE you need to enable “Web Test recorder 10.0” add on as:

• Launch IE
• Click on tools or Press Alt + X and click on Manage add-ons
• 
• Navigate to  and select web test recorder 10.0 and click on enable
• 
• Now you should be able to see web test recorder window in IE

You can enable tracing for the following components using the respective config files

• mtlm.exe.config – For MTLM features
• CodedUITestBuilder.exe.config – For coded UI test builder
• QTAgent32.exe.config – For coded UI test

The config files are located at “%ProgramFiles%\Microsoft Visual Studio 10.0\Common7\IDE”

Update EqtTraceLevel or UITestTraceLevel in corresponding files as

• 1 - indicates Errors only
• 2 - indicates Errors and Warnings
• 3 - indicates Errors, Warnings and Information
• 4 - indicates All including Verbose Information

EqtTraceLevel is for all testing tools modules of the executable

UITestTraceLevel  is for UI test modules of the executable

Trace logs helps in debugging and identifying issues better. We can enable trace logs for coded UI tests as:

• Launch regedit and navigate to [HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\EnterpriseTools\QualityTools\Diagnostics]
• Check the key values for

"EnableTracing"=dword:00000001
"TraceLevel"=dword:00000004

• “1” indicates tracing is on “0” indicates tracing is off
• Trace level
• 1 indicates Errors only
• 2 indicates Errors and Warnings
• 3 indicates Errors, Warnings and Information
• 4 indicates All including Verbose Information
• If you don’t find the key download and run the EnableTraceLogs registry file. It enables tracing for all VS testing tools.
• To disable tracing set EnableTracing to 0

The trace files are generated in %temp%\UITestLogs\LastRun\UITestLog.html. The LastRun contains the latest/last run details. The previous run details are stored as PreviousRunXX.

Test impact analysis helps developers to quickly identify the tests(unit/CUIT) that need to be run for the latest code change. It’s one of the features in visual studio 2010 (VS) available in Premium and Ultimate editions. It works with only managed code.

Let me show Test impact analysis with a Sample web application which has a web page and a class along with Test project.

• Launch visual studio 2010
• Click on new project ->Visual C# - Test – Test Project ( make sure you have selected .NET Framework4 to see the test project)
•  
• Give appropriate project name and save the project
• Close VS
• Launch VS 2010
• Click file-> New project - > Web -> select ASP.NET web application
• 
• Give appropriate project name and save the project
• Right click and add new class and close the solution.
• Open the test project and add the website. The solution will look like
• 
• Create a simple method in class file as DisplayText which returns string
•  
• Create unit test for the above method in UnitTest1.cs as
• 
• Launch test impact view by clicking on Test -> Windows - > Test impact view
• 
• If the test impact diagnostic data is not enabled, click on the link in test impact view window to enable it. Alternatively, you can also set it in test settings as below ( Test -> Edit test settings - > Data and diagnostics)
•  
• Now build the solution and run the unit test to baseline data
• Click on Test-> Windows -> Test view
• 
• Select the test method and click on run
• 
• At this point the test impact view will look like
• 
• Now, lets change the code in DisplayText method and add line of code as
•  
• Since there is change in code it shows up in impacted tests as
• 
• Select the impacted test and click on run tests. Make sure the unit test passes to ensure the code change hasn’t effected the test case.
