Unit Testing in Visual Studio

Unit Testing in .NET

• What is (and isn’t) a unit test
• Why write unit tests
• .NET unit testing frameworks
• MSTest, NUnit, xUnit
• The anatomy of a unit test
• Writing and running your first unit test

Unit Testing in Visual Studio

• Testing support in Visual Studio
• MSTest, NUnit, and xUnit test projects
• Test Explorer and other windows
• Project views (table, board, roadmap)
• Changing view layout
• Filtering, grouping, and ordering
• Creating and using custom fields
• Crating charts using Insight

Test-Driven Development (TDD)

• TDD overview and benefits
• Practicing TDD within Visual Studio
• Effectively refactoring code
• Working with legacy code
• Using CodeLens to support TDD and refactoring

Writing Good Unit Tests

• Asking questions about your code
• Path testing (e.g. happy, sad, evil, etc.)
• Right BICEP testing
• Testing for expected exceptions
• Maintaining high-quality test code
• Unit test naming conventions (e.g. BDD
• Organizing unit tests

Leveraging Visual Studio

• Analyzing code coverage
• Using code coverage as a metric
• Data-driven (parameterized) unit tests
• DataRow, DynamicData, and DataSource attributes
• Concurrent testing using Live Unit Testing
• Concurrent testing using NCrunch

Testing Difficult Code

• The need to isolate code under test
• Doubles (dummies, stubs, fakes, and mocks)
• Microsoft Fakes framework (stubs and shims)
• Comparing mocking frameworks
• Using moq .NET mocking framework
• Debugging and profiling slow-running unit tests
• Using IntelliTest with legacy code
