(Not to happy with this, or the similar changes to elemHide. Open to suggestions
if you can see a cleaner way.)

How about you use sandboxed-module ;). The following configuration should do to
get internal variable exported, for unit tests only:

  sourceTransformers: {
    exportInternalVars: function(source)
    {
      let needExport = {
        "cssRules": ["filters"],
        "elemHide": ["filterByKey", "exceptions"]
      };

      let basename = path.basename(this.filename, ".js");
      if (needExport.hasOwnProperty(basename))
        for (let varName of needExport[basename])
          source += `Object.defineProperty(exports, '${varName}', {get: () =>
${varName}});`;
      return source;
    }    
  }

+  {
+    return filters;
   }
 };
