I'm not sure why we need a second test case. Both simply test that reporting a
grammar error at a specific location results in a green underline.

I think we should report grammar error where it exactly is, similarly to other
examples here. That looks better in pixel result. Otherwise the whole sentence
will be marked in green but in inline_spelling_markers.html we expect grammar
error at (4, 3) and (32, 5)

+        {"the the adlj adaasj sdklj. there there", 32, 5},
         {"zz apple orange.", 0, 16},
     };
     for (size_t i = 0; i < ARRAYSIZE_UNSAFE(grammarErrors); ++i) {
         size_t offset = 0;
         string16 error(grammarErrors[i].text, grammarErrors[i].text + strlen(grammarErrors[i].text));
         while ((offset = stringText.find(error, offset)) != string16::npos) {
             results->push_back(WebTextCheckingResult(WebTextDecorationTypeGrammar, offset + grammarErrors[i].location, grammarErrors[i].length));
             offset += grammarErrors[i].length;
         }
     }
     return false;
 }
 
 }
