Automated tools for error prevention and error detection exist for many high-level languages, but have been nonexistent for assembly-language programs, embedded programs in particular. We present new tools that improve the quality and reliability of assembly-language programs by helping the educator automate the arduous tasks of exposing and correcting common errors and oversights. These tools give the educator a user-friendly, but powerful means of completely testing student programs. The new tools that we have developed are the result of years of research and experience by the authors in testing and debugging students' programming assignments. During this time, we created a few preliminary versions of these automated tools, allowing us to test our students' projects in one fell swoop. These tools gave us the ability to catch stack errors and memory-access errors that we would not have been able to detect with normal testing. These tools considerably shortened the amount of testing time and allowed us to detect a larger group of errors.

Most programming errors are reasonably simple to understand and detect. One of the benefits of a high-level language is its encapsulation of error-prone concepts such as memory access and stack manipulation. Assembly-language programmers do not have this luxury. In our quest to create automated error-prevention and error-detection tools for assembly language, we need to create a comprehensive list of possible errors. We are not considering syntax errors or algorithmic errors. Assemblers, simple testing, and automated testing can detect those errors. We want to deal with design errors that are direct byproducts of the assembly-language environment or result from a programmer's lack of understanding of the assembly-language environment. Over many years of assembly-language instruction, we have come across a plethora of errors. Understanding the different types of errors and how to prevent and detect them is essential to our goal of creating automated error-prevention and error-detection tools. In this paper we list and explain the types of errors we have cataloged.

DynaTest and beyond: From dynamic testing to automated error-prevention and error-detection

JOURNAL OF COMPUTATIONAL METHODS IN SCIENCES AND ENGINEERING 2005年第1期5卷 S1-S12页

DynaTest, which stands for Dynamic Tester, is a macro-language software-testing and validation system that verifies programs, subroutines, and interrupt-handler routines written in assembly language. A scriptwriter writes a DynaTest test driver in a test-script language that specifically supports the development of test scripts. DynaTest uses comparative analysis of a combination of automatically generated pseudo-random test cases and handpicked test cases against a known, working solution. The current version of DynaTest executes on specific hardware platforms. The documented results speak for themselves. Using DynaTest has improved error detection tremendously while dramatically decreasing test-preparation time. Unfortunately, no matter how impressive DynaTest is, it always faces the limited-resource constraints of small microprocessors in embedded systems. With the ever-increasing performance of today's personal computers, a simulated embedded-processor environment opens the way for numerous possible error-prevention and error-detection tools. By wrapping these tools around a simulated embedded-processor environment, we can completely control and analyze the execution phase of a software system. Many tools for high-level languages work by incorporating themselves into the target program, affecting the memory layout and timing of the code. With our tools, we do not modify the target program, and the simulated environment keeps the timing and the memory map unchanged.
