Well Erlang does not have an enum per se, but you can have unions of atoms. We can calculate branch coverage using the below formula: list.add(Foo); Fixing these problems is easy if you can find them, but in order to find them, you need to supply data that truly represents all of the possible inputs to the code. Code coverage isn't everything; bugs can still exist in code with 100% coverage. Heres a simple code example, assuming x, y, and z are booleans: If ( (x||y) && z) { doSomethingGood(); } else {doSomethingElse();}. The Element column gives the packages in the current application.
