C# Unit Testing

Overview
The course provides a thorough introduction to the NUnit testing framework. It covers the concepts underlying unit testing, and the way these concepts are realised in the NUnit framework. The procedures for setting up NUnit and using it in C# development projects are covered in detail. The hands on exercises will familiarise students with test-driven development as a methodology for implementing highly reliable C# code.

Course Benefits
At the end of the course student will know

• about NUnit's role in C# testing
• how to setup, integrate and work with NUnit
• how to design, implement and carry out NUnit tests
• follow best practices in testing and software development
• improve their effectiveness in software testing and the quality of the code they are developing

Key Delivery
Instructor led in-house training with a great deal of hands-on practice.
