Measuring Mc Dc Coverage Of Pair 2 levels of code coverage code coverage can be measured in a variety of ways. the most common approach is to measure one or a combination of one or more of the following: statement coverage, branch coverage, and modified condition decision coverage (mc dc). the following sections will describe each of these coverage types in detail. • this part of the project is concerned primarily with measuring mc dc coverage using test cases generated by pair wise testing. • future parts include research into how to improve mc dc coverage of pair wise test suites and developing tools that integrate these two testing techniques into one framework.
Mc Dc Coverage A Critical Testing Technique Qa Systems As detailed in “multiple code coverage modes”, page 16, several code coverage modes are available for measuring mc dc, condition, and decision coverage. before adapting the build process for trace32 code coverage measurement, you must choose the appropriate code coverage mode. This means that the mc dc analysis really needs to track executed test vectors and analyze them to find pairs of test vectors in order to ascertain whether the mc dc constraints are satisfied for each condition. Mc dc includes all measure points for decision coverage. additionally, for each atomic condition in a decision, an independence pair of true false combinations has to be tested, showing that the condition can independently determine the value of the decision. Please note: the tessy coverage instrumentation for mc dc coverage has been extended in v3.1 to include measurement of switch statements as branch points which was previously covered only by the branch (c1) coverage.

What is mc dc? “modified condition decision coverage” a metric pertaining to conditions in a boolean expression decision in which: each condition has been shown to affect that decision outcome independently “modified” refers to changing the test input to yield a different test path given 2n total possible test paths (exponential). However, there is no direct mc dc support. i believe that people just approximate mc dc with branch coverage. for side effect free expressions like (b && c) || a, there might be avenues for compiler transformation into a tree style bdd, such as a || (b && c). however, i don't know the presence of such tools. efficient test coverage measurement for mc dc describes a code instrumentation.
