Testing is a vital aspect of verifying the design of a software system. This is especially true in a real-time embedded environment, where the system may be subject to strict safety or reliability requirements.

This course introduces the concepts and practice of testing embedded software across the entire development lifecycle. It covers testing software in an embedded environment and is a mixture of lectures and practical exercises. 

Attendees will also perform practical exercises in software verification and Agile development practices.

Course objectives:

  • To understand the need for testing in an embedded environment
  • To give an understanding of the test process
  • To understand the objectives of Agile Programming methodologies
  • The importance of testing in Refactoring
  • To identify the different types of testing and where and when they should be used

Delegates will learn:

  • How to create their own test harnesses
  • The use of test harnesses for embedded systems
  • Integration testing using test doubles
  • How to develop in a Test-Driven Development style.


Attendees should have a good working knowledge of the C language, and experience of simple programming structures: Linked lists, arrays, etc 

Who should attend:

The course is designed for software engineers working in an embedded, real-time environment. The target audience is engineers who have to create and also test their own code. The course is also highly beneficial for test engineers new to software testing in a real-time environment.
