Why ember test –server was failing

When I tried to run ember test –server on my Linux machine I got the following:

$ ember test --server

All my mac friends were doing fine. What was the matter?

Solution: I needed to install the right watchman. As the doc says:

Note, there exists a similarly named npm package (watchman) which is not the intended installation.

I’d fallen for that one. Once I installed the correct watchman, ember test –server yielded the screen I was looking for:

ember-test-server-working
