Ember test "No tests were run"

I am trying to test my code in Ember.js. However when I run ember test --filter="my-test", I get No tests were run, please check whether any errors occurred in the page (ember test --server) and ensure that you have a test launcher (e.g. PhantomJS) enabled.

I am using Ember 2.7.0, node 4.4.7, and OS darwin x64.

In fact, my project structure is somewhat complex.

I have multiple projects, A, B and C. Because project B and C have a lots of similar code, I made A an addon, B and C are just normal projects. By doing that I can reuse my code written in A because all of them will be copied into B and C.

When I run ember s, I run under B directory. Everything works fine.

Now suppose I want to test a component written in A, called nav-bar. And my test is my-test.js

I ran ember test --filter="my-test" under B directory. Then I got No tests were run error.

If I run it under A directory, I got

Error: Version "0.1.2" not compatible with "^0.1.3"

How can I get my test to work? thank you.
