Identifies the method to run before the test to allocate and configure resources needed by all tests in the test class. This class cannot be inherited.
Assembly: Microsoft.VisualStudio.QualityTools.UnitTestFramework (in Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll)
Thetype exposes the following members.
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from Attribute.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|IsDefaultAttribute||When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)|
|Match||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|_Attribute::GetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_Attribute::GetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_Attribute::GetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_Attribute::Invoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
When run in a load test, the method marked with this attribute will run once for every virtual user iteration in the test. If you need to do initialization operations once, that apply to the entire test, use the ClassInitializeAttribute.
The order that methods will be run is:
Methods marked with the AssemblyInitializeAttribute.
Methods marked with the ClassInitializeAttribute.
Methods marked with the .
Methods marked with the TestMethodAttribute.
This attribute can be specified on a method. Only one instance of this attribute may be applied to a method.
This attribute is used by default in generated code.

The SampleClassLib namespace contains the DivideClass class, which in turn contains the method we want to test. This method is called DivideMethod().
In the following code, the DivideClassTest test class contains a test method called DivideMethodTest. This code also contains attributes that control the initialization and clean-up execution order for the method, class, and assembly.
In particular, note the TestInitialize attribute on the Initialize() method.
