It's really hard for ricow@ and kustermann@ to keep our testing infrastructure
stable they don't know what is going on. In this particular case, had
kustermann@ been involved in the review, the chances are high that he would have
caught the following problem: this doesn't work with the new way dart2js handles
CSP mode.

The CSP builder turned red, partially due to this CL:
http://build.chromium.org/p/client.dart/builders/dart2js-drt-linux-csp-be/bui...

Recently dart2js has been changed to emit a "test.precompiled.js" in addition to
"test.js". In csp mode the precompiled version has to be used instead of the
normal one, you can see that below in the else branch.

+          }
+          new File(htmlPath).writeAsStringSync(htmlContents);
         }
       } else {
         htmlPath = '$tempDir/test.html';
         if (isWrappingRequired && !isWebTest) {
           // test.dart will import the dart test.
           _createWrapperFile(dartWrapperFilename, filePath);
         } else {
           dartWrapperFilename = filename;
         }
