Unit Testing in Visual Studio 2017

This two-day, instructor-led Unit Testing in Visual Studio 2017 training class provides students with the knowledge and skills to effectively use Visual Studio to design, write, and run high-quality .NET unit tests. The course focuses on the applicable features and capabilities of Visual Studio as it relates to unit testing and Test-Driven Development (TDD). This course also introduces other, popular unit testing tools and techniques, and demonstrates how they integrate with Visual Studio and your development lifecycle.

This course is intended for current software development professionals who are involved with building high-quality .NET applications. Students will use Visual Studio while learning how to design, write, and run unit tests. They will also learn many relevant practices and techniques, such as TDD, CI, refactoring, and how to test difficult code.

  3. Learn to learn about popular unit testing frameworks.
  4. Learn to learn about the anatomy of a unit test.
  5. Learn to learn about the 3A pattern (Arrange, Act, Assert).
  6. Learn to learn about assertions.
  7. Learn to learn about expected exceptions.
  8. Learn to learn about test class inheritance.
  9. Learn to learn about testing support by Visual Studio edition.
