In computer programming, a characterization test (also known as Golden Master Testing [1]) is a means to describe (characterize) the actual behavior of an existing piece of software, and therefore protect existing behavior of legacy code against unintended changes via automated testing. This term was coined by Michael Feathers.
Many software products have experienced problems with old legacy source code; for example: Legacy code may not have been designed under a defensive programming initiative, and might therefore be of much lower quality than newly designed source code. Legacy code may have been written and tested under conditions which no longer apply.
Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.
As a result, legacy systems are typically modernized incrementally. Initially, the system consists completely of legacy code. As each increment is completed, the percentage of legacy code decreases. Eventually, the system is completely modernized. A migration strategy must ensure that the system remains fully functional during the modernization ...
Legacy systems are considered to be potentially problematic by some software engineers for several reasons. [4]If legacy software runs on only antiquated hardware, the cost of maintaining the system may eventually outweigh the cost of replacing both the software and hardware unless some form of emulation or backward compatibility allows the software to run on new hardware.

Software archaeology or source code archeology is the study of poorly documented or undocumented legacy software implementations, as part of software maintenance. [1] [2] Software archaeology, named by analogy with archaeology, [3] includes the reverse engineering of software modules, and the application of a variety of tools and processes for extracting and understanding program structure and ...
question you're working on. 2. Read Part One and Part Two as preparation for your workshop, perhaps making notes as you read. When you've finished, set aside three hours and write your answers to the questions in Part Three. Whatever your choice, enjoy the journey! THE TURNING POINT The idea started on New Year’s Day in 1980, when my ...
