Error is thrown if test values.yaml is empty in helm based deployers

[vcanaa]

If test values.yaml is empty, the yaml parser returns None when the deployer tries to overlay it on top of the real values.yaml

Traceback (most recent call last):
File "/bin/overlay_test_files.py", line 45, in
overlay_yaml_file(orig, dest)
File "/bin/yaml_util.py", line 47, in overlay_yaml_file

File "/bin/yaml_util.py", line 30, in add_or_replace
for key in orig:
TypeError: 'NoneType' object is not iterable

I can confirm this is still an issue. Does anyone know of a fix or workaround?

I ended up defining a value that is not used anywhere or defined in any of the subcharts:

Chart values.yaml:

placeholder: {}

Annoying but effective. 🙂
