Course#: TC201

About this Course

Course Type Course Code Duration
Embedded Software TC201 2 Days

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.

Why Attend this Course?

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.

What Makes this Course Stand Apart?

What you 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


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.


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