Pex - Automated Whitebox Testing for .NET : Supported Test Frameworks

Supported Test Frameworks

Pex supports the following test frameworks:

Attribute Usage Table

Feature Visual Studio Unit Test Description
fixture [TestClass, PexClass] [PexClass] tests are logically grouped in a type
parameterized test [PexMethod] instance method tagged with PexMethod same
fixture setup [ClassInitialize] supported not supported
fixture teardown [ClassCleanup] supported not supported
test setup [TestInitialize] supported not supported
test teardown [ClassCleanup] supported not supported

All other attributes are copied to the generated unit tests but their function is not understood.

  • For VSTS, the ITestContext instance is always null.

Specifying up the test framework

Pex automatically guesses the test framework by walking the list of assembly references of the test project and looking for the unit test framework assembly. If Pex cannot guess the test framework you are using, you can set it with the TestFramework option of the PexAssemblySettingsAttribute.
