Add option to git diff between last 2 local commits about chart-testing HOT 6 CLOSED

I assume this is the repo: https://github.com/monotek/helm-charts

Give this is a repo that's supposed to be added to the hub, I'd say it would make sense to test charts before they make it to master.

I agree that it would be quite useful to not only diff to HEAD but to a configurable commit passed via a flag:
Tested and valid helm charts live on the master branch and changes can only be done by opening a PR and ensuring the helm chart tests pass.
After merging the PR I want to git diff .. with the previous commit HEAD~1 to be able to detect the changes, test again and finally push the chart to a helm repository.

Coud your explain your workflow? Generally speaking, this tool is meant to test changes against a target branch before they are merged. In your case, the chart already seems to be on the target branch. Why is this? Can you elaborate?

I've pushed directly to master without using a pr but still wanted the travis ci pipline to do the tests...

Yes, of course. The repo was more or less a test to copy the old helm/stable repo workflow without the need to have own infrastructure. At the end i wanted to have the repo on Github pages (https://monotek.github.io/charts/index.yaml via https://github.com/monotek/monotek.github.io ) and the upload to that repo should be triggered after succesful test in https://github.com/monotek/helm-charts.

This would be useful. We were able to work around it by setting target-branch to master^ if we detected that HEAD and origin/master (our remote and target branch) were the same commit hash (and that there were no diffs in the files).
