    Test Case Generation for Adequacy of Floating-point to Fixed-point Conversion
    (2010) Pham, Hung T.; Truong, Anh-Hoang; Chin, Wei-Ngan; Aoshima, Takenobu
    Porting an application written for personal computer to embedded devices requires conversion of floating-point numbers and operations into fixed-point ones. Testing the conversion hence requires the latter be as close as possible to the former. The closeness is orthogonal to code coverage and requires different strategies to generate a test suite that reveals the gap between the two functions. We introduce a new test adequacy criterion and propose several metrics to quantify the closeness of two functions. After that we propose a method to generate a better test suite from a given one for the test adequacy criteria. We also show experimental results on some well-known mathematical functions.
