           The thing we are testing is called a "System under test" (SUT) (XTD) or "object under test" (POODR, p. 195, Figure 9.1). We'll use SUT. It is fair to think about other things being under test, such as a class, object, method, or application, but the idea here is that the thing under test is defined by the scope of the test itself. Other objects may be involved, such as a "depended-on component" (DOC).
