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.
Engineers require a good knowledge of how to test their code but in addition they must understand other techniques to find and eliminate errors earlier in the design lifecycle.
Supporting testing are the concepts of configuration and change management, vital skills required for managing industrial software.
A four day course covering testing software in a real-time embedded environment. The course is a mixture of lectures and practical exercises.
- To understand the need for testing in an embedded environment
- To develop practical testing skills
- To give an understanding of the test process and how it fits with the development lifecycle
- To identify the different types of testing and where and when they should be used.
- To introduce good testing practices
Delegates will learn:
- How to perform static analysis of code
- The creation of black box test harnesses
- The creation of white box tests
- An understanding of software metrics
- How to create tests from Use Cases
Attendees should have a practical working knowledge of the C language.
Who should attend:
This 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. This course is also highly beneficial for test engineers new to software testing in a real-time environment.
- Four days
- Delegate handbook
At least a third of the course is devoted to practical exercises. Delegates will gain hands-on experience developing test harnesses, static analysis and software metric analysis.
