This is a course for developers, designed to bring about a fundamental change to the way developers go about their day-to-day business of writing software code. Instead of thinking about unit tests as at best an afterthought, having already written the application code, the course aims to turn this practice on its head, and get programmers to write tests before the code to be tested.
Originating in the Agile methodology of Extreme Programming, Test Driven Development (TDD) has become accepted as a mainstream best practice, and is being adopted by major organisations as a means of improving code quality and developer productivity. Because Test Driven Development involves such a major inversion of most developers' ways of thinking and working, the course is strongly exercise based . Typically developers find TDD initially strange, but go on to find it quite liberating, and become 'test infected' (unable to write code without having first devised unit tests.) The exercises are based on the C# programming language using Visual Studio, MSTest, NUnit2,Nunit3, Xunit, NCrunch, Moq, Fluent Assertions and Specflow. All of these operating in a client-only GIT environment.
Competence in C#
At the end of this course you will have:
- The ability to take the TDD approach to software development
- An understanding of the key techniques and strategies of TDD, and principles of refactoring code
- The ability to write unit tests in MSTest, NUnit2, Nunit3, Xunit
- Understand the async and parallel capabilities of these unit testing frameworks
- To understand the benefits that NCrunch offers
- The ability to use mock objects in unit tests
- Work with Specflow to produce automated Acceptance Tests
The traditional approach : Test-Last
- Introduce enough GIT (client) to allow local s/w control throughout the course
Introduction to Unit Test (2 chapters)
- MSTest, Nunit, NCrunch, Fluent Assertions.
- For the introduction we use NCrunch which effectively hides the underlying unit test framework.
Data-Driven unit tests
- How this is achieved in MSTest, Nunit2, Nunit3 and Xunit
- Using Moq
- Advice on fitting unit test philosophy into Code Contracts, WinForms, WebForms, WPF, MVC, Entity Framework
- Moving beyond Unit Test into automated Acceptance Tests using Specflow

How do QA’s online courses work?
QA online courses, also commonly known as distance learning courses or elearning courses, take the form of interactive software designed for individual learning, but you will also have access to full support from our subject-matter experts for the duration of your course. When you book a QA online learning course you will receive immediate access to it through our e-learning platform and you can start to learn straight away, from any compatible device. Access to the online learning platform is valid for one year from the booking date.
All courses are built around case studies and presented in an engaging format, which includes storytelling elements, video, audio and humour. Every case study is supported by sample documents and a collection of Knowledge Nuggets that provide more in-depth detail on the wider processes.
