Since the release name is always set to the chart name and a random identifier, if the chart name is long it can interfere with other Kubernetes pods and resources that also have randomly generated identifiers appended.

Being able to specify the release name with a new flag (e.g. --release-name) would be great.

I have a PR ready with the contribution to make this possible. If you could approve it (and perhaps make a new release of chart-testing soon), that would be fantastic.
