Desired functionality.

Code coverage should work as expected

Mention any other details that might be useful.

For some reason .tmp folder files got included in test coverage report

Hi @valorkin,

fix(test) is not an actual scope. This seems like it's fix(@angular/cli). I'll reword your commit, but please keep that in mind next times you submit PR.

[valorkin]

sure, thank you!
