i use https://github.com/angularclass/angular2-webpack-starter , have foloowing problem: when i'm in project directory , run

karma start 

then get:

summary:

✔ 0 tests completed

but when run:

npm test 

i get:

summary:

✔ 0 tests completed

npm err! test failed. see above more details.

if run:

npm run test 

i get:

summary: ✔ 0 tests completed  npm err! darwin 16.1.0 npm err! argv "/usr/local/cellar/node/7.1.0/bin/node" "/usr/local/bin/npm" "run" "test" npm err! node v7.1.0 npm err! npm  v4.0.2 npm err! code elifecycle npm err! angular2-webpack-starter@5.0.5 test: `karma start` npm err! exit status 1 npm err!  npm err! failed @ angular2-webpack-starter@5.0.5 test script 'karma start'. npm err! make sure have latest version of node.js , npm installed. npm err! if do, problem angular2-webpack-starter package, npm err! not npm itself. npm err! tell author fails on system: npm err!     karma start npm err! can information on how open issue project with: npm err!     npm bugs angular2-webpack-starter npm err! or if isn't available, can info via: npm err!     npm owner ls angular2-webpack-starter npm err! there additional logging output above.  npm err! please include following file support request: npm err!     /users/kamil/desktop/code/officewise/officewise_frontend/npm-debug.log 

any idea remove npm err? important me because use external system run tests , report errors of new commits in repository (my node version v7.1.0 (lastest), npm version 4.0.2 (lastest), mac os sierra).
