How to find the failed test: One of your tests timed out

I’m doing the exercise “phone number”, all tests were passed on my local host. Then I submitted it to exercism, and got error message:

One of your tests are timed out

there’s no further detailed information.

How to find which test timed out? Thanks.

The timeout applies to the entire test suite. Timeouts aren’t on a per test basis. You could try making a whitespace change and running again. Sometimes that helps when the issue is on the infrastructure.

The Phone Number exercise is unlikely to generate solutions that genuinely time out. @yuwendai if your solution passes within a second locally then this is most certainly an infrastructure issue.
