Error with karma unit tests

[popod]

When running unit tests with karma, I've this error:

ERROR in ./app/node_modules/keytar/lib/keytar.js
Module not found: Error: Can't resolve 'node-loader' in '/rootPath'
 @ ./app/node_modules/keytar/lib/keytar.js 1:13-52
 @ ./app/src/renderer/routes.js
 @ ./app/src/renderer ^\.\/(?!main(\.js)?$)
 @ ./test/unit/index.js

What should be the problem ?

My bad.. node-loader was not installed in devDependencies !
