operator-sdk test local ./test/e2e --up-local --namespace=memcached

What did you expect to see?
Test pass.

What did you see instead? Under which circumstances?

@camilamacedo86 I'm facing the same problem with my project too.

[camilamacedo86]

Hi @AlexNPavel could you give a hand here to us? I understand that he is using the sample.

[pratikjagrut]

@camilamacedo86 and @AlexNPavel If I run go test ./test/e2e/... -namespacedMan /tmp/namespace-init.yaml -globalMan /tmp/cache_v1alpha1_memcached_crd.yaml -root $GOPATH/src/github.com/operator-framework/operator-sdk-samples/memcached-operator -v -parallel=2 -localOperator test is passing.

[pratikjagrut]

@camilamacedo86 My apologies, I didn't know that operator-sdk test local ./test/e2e --up-local --namespace=memcached this won't create ns namespace=memcached if not present and will fail the test due to not finding ns. So closing this issue.
