Embedded systems have overwhelming penetration around the world. Innovations are increasingly triggered by software embedded in automotive, transportation, medical-equipment, communication, energy, and many other types of systems. To test embedded software in a cost effective manner, a large number of test techniques, approaches, tools and frameworks have been proposed by both practitioners and researchers in the last several decades. However, reviewing and getting an overview of the entire

Also unfortunately, we often see that some companies reinvent the wheel (by designing a test approach new to them, but existing in the domain) due to not having an adequate overview of what already exists in this area. To address the above need, we conducted a systematic literature review (SLR) in the form of a systematic mapping (classification) in this area. After compiling an initial pool of 560 papers, a systematic voting was conducted among the authors, and our final pool included 272 technical papers. The review covers the types of testing topics studied, types of testing activity, types of test artifacts generated (e.g., test inputs or test code), and the types of industries in which studies have focused on, e.g., automotive and home appliances. Our article aims to benefit the readers (both practitioners and researchers) by serving as an "index" to the vast body of knowledge in this important and fast-growing area.
