this wasn't really using testChecker for anything ... when reporter was set, it
bypassed all of the error validation. It was just used for creating the Compiler
instance, so inlined that here.

-        createReporter: (x) => reporter = new SummaryReporter(x));
+    var provider = createTestResourceProvider(files);
+    var uriResolver = new TestUriResolver(provider);
+    var srcOpts = new SourceResolverOptions(
+        entryPointFile: '/main.dart', useMockSdk: true);
+    var context = createAnalysisContextWithSources(
+        new StrongModeOptions(), srcOpts, fileResolvers: [uriResolver]);
+    var reporter = new SummaryReporter(context);
+    new Compiler(new CompilerOptions(sourceOptions: srcOpts),
+        context: context, reporter: reporter).run();
 
     _verifySummary(GlobalSummary summary) {
       var mainLib = summary.loose['file:///main.dart'];
