ICS2002-12-01: JBlanket: Support for Extreme Coverage in Java Unit Testing - J. Agustin

nit testing is a tool commonly used to ensure reliability in software development and can be applied to the software development process as soon as core functionality of a program is implemented. In conventional unit testing, to properly design unit tests programmers will need to have access to specifications and source code. However, this is not possible in Extreme Programming (XP), where tests are created before any feature of a system is ever implemented. Obviously, XP's approach does not lead to improper testing, but instead leads to a different approach for testing. JBlanket is a tool developed in the Collaborative Software Development Laboratory(CSDL) at the University of Hawai'i (UH) that is meant to assist these types of "unconventional" testing that calculates method-level coverage in Java programs, a coarse enough granularity of test case coverage whereby programmers will not only be able to ensure that all of their unit tests pass, but will also be able to test all of their currently implemented methods. Unit testing where 100 percent of all unit tests must pass that also exercises 100 percent of all non-trivial remaining implemented methods is called Extreme Coverage. This research will attempt to show that Extreme Coverage is useful in developing quality software.
