java.lang.Objectorg.junit.runner.Description
public class Description
A Description describes a test which is to be run or has been run. Descriptions
can be atomic (a single test) or compound (containing children tests). Descriptions are used
to provide feedback about the tests that are about to run (for example, the tree view
visible in many IDEs) or tests that have been run (for example, the failures view).
Descriptions are implemented as a single class rather than a Composite because
they are entirely informational. They contain no logic aside from counting their tests.
In the past, we used the raw TestCases and TestSuites
to display the tree of tests. This was no longer viable in JUnit 4 because atomic tests no longer have
a superclass below Object. We needed a way to pass a class and name together. Description
emerged from this.
