Discussion:
go test ./cmd/kubeadm/... fails with: it appears to be following a "RunCmd" pattern used by e2e tests, but unit tests should not require built binaries
can work on this
has a long discussion as to why this is. These tests only get run when gets run, which will produce the needed binary and pass it in as arg. For more information, authored this and should be able to provide more details.
Yup, the target explicitly ignores these tests: and like said, runs this script as part of its target:
then the test should have build tags to exclude it from a regular run of the package
or up for fixing that?
I thought build tags only works on the OS level or if you it would ignore it completely? Wouldnt break the command as well?
I'd also tolerate skipping the test if the built binary doesn't exist
I think that is a great solution. I think in I had initially suggested something like that. If everyone is ok with that, I will go ahead and make that change.
Sounds good, make that change and we'll see how it turns out. I'd really want these tests start working, so +1
