Coverage types

Code Coverage for Ada, Java, C and C++

The Code Coverage feature provides the capability of reporting of various source code units and branches, depending on the coverage type selected.

By default, Code Coverage implements full coverage analysis, meaning that all coverage types are instrumented by source code insertion (SCI). However, in some cases, you might want to reduce the scope of the Code Coverage report, such as to reduce the overhead generated by SCI for example.

Branches

When referring to the Code Coverage feature, a branch denotes a generic unit of enumeration. For each branch, you specify the coverage type. Code Coverage instruments each branch when you compile the source under test.
