Test Classes

Configuration related

  Class Description
Public class TestConfiguration Provides access to a TestConfigurationSection that represents the microsoft.visualstudio.testtools section in an app.config file.
Public class TestConfigurationSection Provides access to data source configuration data.
Public class TestsContext Used to store information that is provided to unit tests.

Objects and Types

  Class Description
Public class Private Object Allows test code to call methods and properties on the code under test that would be inaccessible because they are not public.  Automatically generated by the framework.
Public class PrivateType Represents the type of a private class that gives access to private static implementations.

Assert classes for test verification

 th style="BORDER-RIGHT-STYLE:none;TEXT-ALIGN:left">Class
 Description
Public class Assert Verifies conditions in unit tests using true/false propositions.
Public class CollectionAssert Verifies true/false propositions associated with collections in unit tests.
Public class StringAssert Verifies true/false propositions associated with strings in unit tests.

Exception classes

 Class Description
Public class AssertInconclusiveException Used to indicate that a test is not yet implemented.
Public class AssertFailedException Used to indicate failure for a test.
Public class UnitTestAssertException This is the base class for unit test exceptions.
Public class InternalTestFailureException The exception that is thrown to indicate an internal failure for a test.


Test Class and Methods

   Class Description
Public class TestClassAttribute Used to identify classes that contain test methods. This class cannot be inherited.
Public class TestMethodAttribute Used to identify test methods. This class cannot be inherited.

Attribute classes used  like [AssemblyInitialize()] etc in the attribute for a method .  

Initialization Attributes

The order of the methods in the unit test will be run is specified by the attributes:
  1. Methods marked with the AssemblyInitializeAttribute.
  2. Methods marked with the ClassInitializeAttribute.  (used for initialization only once to the entire test)
  3. Methods marked with the TestInitializeAttribute.  (run once for every user iteration.)
  4. Methods marked with the TestMethodAttribute.
  ClassDescription
Public classAssemblyInitializeAttributeIdentifies a method that contains code to be used before all tests in the assembly have run and to allocate resources obtained by the assembly. This class cannot be inherited.
Public classClassInitializeAttributeIdentifies a method that contains code that must be used before any of the tests in the test class have run and to allocate resources to be used by the test class. This class cannot be inherited.
Public classTestInitializeAttributeIdentifies 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.

Cleanup Attributes

  ClassDescription
Public classAssemblyCleanupAttributeIdentifies a method that contains code to be used after all tests in the assembly have run and to free resources obtained by the assembly. This class cannot be inherited.
Public classClassCleanupAttributeIdentifies a method that contains code to be used after all the tests in the test class have run and to free resources obtained by the test class. This class cannot be inherited.
Public classTestCleanupAttributeIdentifies a method that contains code that must be used after the test has run and to free resources obtained by all the tests in the test class. This class cannot be inherited.

Modifier Attributes for TestMethod

  ClassDescription
Public classExpectedExceptionAttributeIndicates that an exception is expected during test method execution. This class cannot be inherited.    E.g. [ExpectedException(typeof(System.DividedByZeroException)]
Public classIgnoreAttributeIndicates that a specific test should not be run. This class cannot be inherited.  [Ignore()] (the test will be greyed out).
Public classTimeoutAttributeUsed to specify the time-out period of a unit test in milliseconds.
Public classDescriptionAttributeUsed to specify the description of the test. This class cannot be inherited.  e.g. [Description("test")]
Public classDataSourceAttributeProvides data source-specific information for data-driven testing. This class cannot be inherited.  Examples are: 

[DataSource("Provider=SQLOLEDB.1;Data Source=MySource;Integrated] Security=SSPI;Initial Catalog=MyCatalog;Persist Security Info=False", "MyTable")]

[DataSource("dataSourceNameFromConfigFile")]

Public classTestPropertyAttributeEstablishes a test specific property on a method. This class cannot be inherited.  e.g. [TestProperty("Name", "value"]

Other Attributes

  ClassDescription
Public classCssIterationAttributeRepresents the project iteration to which this test corresponds. This class cannot be inherited.
Public classCssProjectStructureAttributeRepresents the node in the team project hierarchy to which this test corresponds.
Public classDeploymentItemAttributeUsed to specify deployment items such as files or directories for per-test deployment. This class cannot be inherited.   Used for create Test Deployment.
Public classHostTypeAttributeUsed to specify the type of host that this unit test will run in. This class cannot be inherited.   Currently only one type type, i.e. [HostType("ASP.NET")]
Public classOwnerAttributeUsed to specify the person responsible for maintaining, running, and/or debugging the test. This class cannot be inherited.
Public classPriorityAttributeUsed to specify the priority of a unit test. This class cannot be inherited.
Public classWorkItemAttributeUsed to specify a work item associated with a test.
