+IDEAS FOR TESTING RENAMING OF MIRROR CALLS
+
+1) Rough skeleton:
+
+Map<Element, ElementAst> elementAsts = partiallyCompile(<source>); (How can we do this?)
+
+Assert elementAsts is as expected

Precisely what do you mean by "expected"?

Added tests.

+
+Map<Node, String> renames = new ...
+
+Map<LibraryElement, String> imports = new ..
+
+MirrorCollector collector = new MirrorCollector(renames, imports, compiler, elementAsts);
+
+for(Element e in elementAsts.keys) {
+  collector.collect(e);
+}
+Assert renames and imports have appropriate entries.
+
+
+Do the above with sources affecting all paths in mirrorCollector
+
+2) If the above not possible maybe manually construct the parts needed by mirrorCollector,
+   and call its methods directly.
+
+3) Later tests should test that the actual MirrorHelper library is called,
+   which should be doable by writing small test programs, compiling and running them.
+
+4) Even later, the MirrorHelper library should also be testet on its own with
+   hand-written sample programs as they would come out of compiling.
