Testing is an integral part of the software development process for embedded systems and its necessity to attain software quality is undisputed. This document gives a comprehensive overview on aspects of unit tests of embedded software and presents a suitable testing tool: Tessy.

The aim of the Classification Tree Method is to derive a set of test case specifications starting from a functional problem specification.

The objective of this paper is to define some commonly used code coverage measures and to discuss their strengths and weaknesses. Also the relation between the measures will be discussed. Small examples are used to illustrate some measures and to indicate common traps and pitfalls.
Eventually, we will be able to rate the value of code coverage in general and what it means if we have reached 100% of a certain coverage measure.
