When running a large test suite, being able to find a specific test by name is a challenge because the results are not sorted.

If a viewercomparator was added to testviewer then the results could be shown in a sorted order:

in org.eclipse.jdt.internal.junit.ui.TestViewer:

 fTreeContentProvider= new TestSessionTreeContentProvider();
 fTreeViewer.setContentProvider(fTreeContentProvider);
 fTreeLabelProvider= new TestSessionLabelProvider(fTestRunnerPart, TestRunnerViewPart.LAYOUT_HIERARCHICAL);
 fTreeViewer.setLabelProvider(new ColoringLabelProvider(fTreeLabelProvider));
+fTreeViewer.setComparator(new ViewerComparator());

This might need to be an option to allow users to turn it on/off. If the desire to make results sorted all the time is needed then it would probably make sense to modify the org.eclipse.jdt.internal.junit.model.TestSuiteElement to store the elements as a TreeSet sorted by the test name instead:

-private List/*<TestElement>*/ fChildren;
+private SortedSet<TestElement> fChildren;

-fChildren= new ArrayList(childrenCount);
+fChildren= new TreeSet<TestElement>();

(The TestElement would need to implement Comaparable to make that happen, as well as other iteration paths in that class).
