How do you decouple the tests of two functions F and G in which F calls
G? If a code change broke the behaviour of G, then both tests should
fail. Then we run into this problem with the default test runner. To
make F's tests independent of G would require that they pass
*regardless* of the behaviour of G, which seems like an unattainable
goal unless you also decouple F from G, which implies that every tested
function must be a leaf function. Which seems unrealistic.
