Print the rendered chart or section when failure

[cornfeedhobo]

I'm getting the strangest failures that only happen within unittest. When I feed the exact same values to helm, my renders are clean. I need a way to see what unittest is rendered, beyond the tiny little error message.

Hello @cornfeedhobo,

Currently working on it.
Still have some issues with proper handling of feature flags, which is blocking this enhancement.

@cornfeedhobo would you like to share a reproducible scenario showcasing the failure you are facing? I would be interested in trying to help ^^

@cornfeedhobo My workaround is to use the snapshot test.

tests:
  - it: should not change manifest
    templates:
      - deployment.yaml
    asserts:
      - matchSnapshot: {}

I put it as the first test case, and use helm unittest . -u to create a snapshot in the __snapshot__ folder, now I can check how the deployment.yaml is rendered by helm unittest.
