A better test would be to let everything be analyzed with default options, then
change the options in a way that would add or remove errors so that we can see
that the options were actually applied.

Yup, good idea. I updated this to set and unset the generateHints flag (also
found what looks like a bug).

+    standardAnalysisSetup();
+
+    await analysisFinished;
+
+    expect(currentAnalysisErrors[pathname], isList);
+    List<AnalysisError> errors = currentAnalysisErrors[pathname];
+    expect(errors, isEmpty);
+  }
+
+  @override
+  bool get enableNewAnalysisDriver => true;
+}
