cmd tests are not working properly

[kadel]

one example

test result:

===> Starting test <===
convert::expect_success_and_warning: Running: 'kompose convert --stdout -f /home/tomas/dev/goenv/kompose/src/github.com/skippbox/kompose/script/test/fixtures/etherpad/docker-compose.yml' expected_output: '/home/tomas/dev/goenv/kompose/src/github.com/skippbox/kompose/script/test/fixtures/etherpad/output-k8s.json' expected_warning: 'Unsupported key depends_on - ignoring'
PASS: converted output matches
PASS: warning found: 'Unsupported key depends_on - ignoring'

but if I run command manually it fails and there is no output:

My bad, I forgot export env varibales. 😳
When I export proper env variables that are specified in docker-compose.yml it works properly.
