@yyx990803 I noticed that the weex test case is failed here and in many other PRs, but the modified codes have nothing with weex. That may because the version of weex-js-runtime is mismatched with these weex test cases.

Actually, the codes of weex in this repo are a little outdated, including the test cases. I can sync the codes and fix the ci, but I have to wait for these PRs to be merged and solve the conflicts with the latest code.
