Attempting to inject an unknown injection: router:main when running unit or integration tests for controllers or routes.

[MiguelMadero]

Note: I think this is low priority since there is a workaround (scroll to the bottom), but I still wanted to open it in case someone runs into the same issue.

Easy repro steps:

$ ember new ember new router-main-injection-not-found && \
  cd router-main-injection-not-found && \
  bower install ember#1.11.4  && \
  ember g route dummy-route && \
  ember test

Note: the same error occurs for 1.11, 1.12, route and controller unit tests.

Expected

The tests should pass.

Actual the test fails with the message Attempting to inject an unknown injection:router:main`. Full log:

Prior to #100 these tests worked fine. https://github.com/zenefits/ember-test-helpers/commit/eb3e171f0c4218bd83e34328c307a8f73e8bb1d9 fixes the issue. {{link-to}} is broken with and without the commit in 1.11 and 1.12.

Based on the description from PR#100 "This ensures they receive no router at all instead of the 1.13-safe one.", I think it's better for those versions to receive a full router instead of no router at all.

Workaround: simply add needs: ['router:main'] to all your route and controller tests or upgrade to 1.13.

I'm getting this as well.

Sorry that this has caused you trouble, but I am going to go ahead and close the issue. The work around seems good enough for now, and Ember < 1.13 is getting very long in the tooth at this point...
