What is White framework?

What is White framework?

White framework is an open-source framework which provides a handful of features to automate UI applications. By using White framework we can simulate a user effectively.  For example, if we want to perform some stereo type actions too many times like Launch an application, Click on a button, select a value, etc.. it might be awkward. If there is no decision making required then it has much worse situation. In these kinds of situations, we can avoid a human being from doing this. Instead we can have automation tool to simulate the human being.

White framework is basically a Test Automation tool, but we can use this to do the automation also. In simple words we can launch an application, can find buttons and other controls, can simulate mouse moves and clicks, activate controls, etc… That means everything which can be possible using Windows APIs.

White framework is developed using .NET 3 runtime. This uses windows UI automation library and Windows messages. If a developer uses white framework he does not worry about the PInvoke related activities. We can say White framework is a wrapper above the UI automation library and Windows messages.

White framework can be used to automate applications which are developed using Win32, WinForms, WPF, Silverlight and SWT (Java) platforms.

Basics Of Attributes in .Net Framework

The Attributes are the declarative informations used to instruct the .Net Runtime. The attributes can work with types, fields, methods and properties. These informations are stored with the metadata file. By using the Attributes the developer can control the CLR. So we will get a dynamic behaviour from the CLR.

Eg:- Serializable is an Attribute.

Usage of Attributes in VB.Net(Sample):

<Serializable()> _
Public Class Employee
Public Name As String
Public Designation As String
End Class

Usage of Attributes in C#.Net(Sample):

public class Employee
public string Name;
public string Designation;

Note: All the attributes are classes that derived from System.Attribute class.

.Net framework has a lot of attributes that can be used for controlling XML serialization, Web services, COM interoperability etc.. And .Net provides the oppertunity to create custom attributes.

Different Methods to Load Assembly Dynamically in .Net

  1. Assembly.LoadFrom : Loads an assembly given its file name or path. Loads the assembly from the specified path, this will not search for the assembly in other directories. If an assembly with the same identity is already loaded, LoadFrom returns the loaded assembly even if a different path was specified.

  2. Assembly.LoadFile : Loads the contents of an assembly file on the specified path.

  3. Assembly.ReflectionOnlyLoad :

  4. Assembly.Load : This method takes the name of the assembly, and the runtime searches for the assembly in different locations. These locations include local directory and global assembly cache.

  5. Assembly.LoadWithPartialName :
