405. Test-Driven Development Using NUnit

405.� Test-Driven Development Using NUnit

Rev. 1.0

An emerging software engineering paradigm is test-driven development, where tests are written early and testing is performed continuously during the development process. Problems are discovered early and corrected when they are found. This one-day course for developers explains the methodology of test-driven development and the use of NUnit in supporting test-driven development on Microsoft .NET.

The course is practical, with many example programs and tests written in C#, including a cumulative case study. The goal is to quickly bring you up to speed in using NUnit in your .NET development projects. The student will receive a comprehensive set of materials, including course notes and all the programming examples.

LEARNING OBJECTIVES

� Understand the principles of test-driven development

� Acquire fluency in developing tests using the NUnit framework

� Efficiently exercise tests suites using both GUI and command-line tools

Duration:� 1 day. There is enough material, including five labs, to run the course over a somewhat longer duration if desired. The instructor guide contains suggestions for pacing.

Prerequisites:� The student should have a basic knowledge of the .NET Framework and experience programming in C# with Visual Studio.
