I think you should just put this file into the test file, and give the model the
ExecuteJavascript method. Nothing else.

+    self._js_host = js_host
+    self._win_idx = win_idx
+    self._tab_idx = tab_idx
+
+  def ExecuteJavascript(self, js):
+    return self._js_host.ExecuteJavascript(
+      js = js,
+      windex = self._win_idx,
+      tab_index = self._tab_idx
+    )
+
+  def ExecuteJavascriptFile(self, fileName):
+    fileJs, fd = (None, None)
+    try:
+      fd = open(os.path.join(os.path.dirname(__file__), fileName), "r")
+      fileJs = fd.read()
+    finally:
+      if fd:
+        fd.close()
+    return self.ExecuteJavascript(fileJs);
