Invalid YAML is generated when exporting a deployment

[bschmalhofer]

In a rel-11_0 installation I exported a simple deployment. The exported file claims to be a YAML file. However yamllint has a different opinion.

Looks like I was fooled by yamllint here. The program complained about missing indention for the list in:

    EffectiveValue:
    - Computer
    - Hardware
    - Location
    - Network
    - Software
    - NamespaceBoden
    IsValid: 1

But the YAML spec says that the item marker - already counts as indention, so the snippet is valid YAML.

I could not immediately find a YAML validator, so I used yq -o json Export_Deployment_8.yml for double checking. That command transformed YAML into JSON without complaints. So the generated file semms to be valid YAML. Double-doublechecking I found that breaking the YAML file also broke the transformation. This is a good thing.

Enhanced the test script. Closing this issue.
