<P style="MARGIN: 0px">This practical, solutions-focused book shows software professionals how to easily and routinely achieve exceptionally high coverage in their unit tests, and use that coverage to significantly improve first-time quality in their software.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">Long-time developer and testing expert Stephen Vance shows why guidelines recommending coverage of 80% of statements (or some other arbitrary number) are insufficient -- and why 100% coverage in multiple metrics is both valuable <I>and achievable</I>. One realistic example at a time, Vance dispels the myth that high coverage unit testing is hard and not worth the effort by demonstrating the implementation patterns and refactorings that make it possible and even easy.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">With Vance’s guidance, you can:</P> <UL> <LI> <DIV style="MARGIN: 0px">Unit test all or virtually all of your code</DIV> </LI> <LI> <DIV style="MARGIN: 0px">Improve the testability of your software designs</DIV> </LI> <LI> <DIV style="MARGIN: 0px">Consistently identify the most effective testing approaches for each project</DIV> </LI> <LI> <DIV style="MARGIN: 0px">Address specialized testing challenges such as databases, threaded code, or legacy upgrades</DIV> </LI> <LI> <DIV style="MARGIN: 0px">Write unit tests that can scale as your applications grow</DIV> </LI> </UL>
