Better document how to run the integration tests

[victornoel]

Actual behavior

I run make integration-test and I get the following output:

++ GCS_BUCKET=gs://kaniko-test-bucket
++ IMAGE_REPO=gcr.io/kaniko-test
++ '[' -f /common.sh ']'
++ echo 'Running integration tests...'

Expected behavior

Either the tests are not working or I'm doing something wrong. I have no way to know if there are things I need to setup beforehand. For the record I just ran dep ensure before running the integration tests.

Additional Information

Using go version go1.13 linux/amd64 on archlinux

[victornoel]

Seems I haven't read closely enough, this is documented in DEVELOPMENT.md

Hi @victornoel this is recent issue issue with go1.13.
See golang/go#34443, golang/go#33475

Can you revert back to go1.12?

[victornoel]

@tejal29 ah indeed, thanks for the feedback, I thought it was just me doing something wrong :)
I will try to see if I can, I'm not clear with go how to change the currently used go version (in js I would use nvm for example, in python pyenv, but in go I have no idea and my linux distribution is using 1.13.1.
