openshiftApply step unit test

[dtschan]

Implement unit test for openshiftApply step which tests:

• Works whether oc is in PATH or not
  • Installs oc if not in PATH
• Executes oc convert -f ${tmpfile} to validate configuration argument
  • Where tmpfile contains the configuration argument of the step
  • Fails when configuration is invalid, e.g.

apiVersion: extensions/v1beta1
kind: Deployment
spec:
  template:
    spec:
      containers:
      - name: mycontainer        
        resources:
          limits:
            cpu: 1   # Wrong type, must be a string
...

or:

apiVersion: v1  # Unknown type, API group is missing
kind: DeploymentConfig
...

• Executes oc apply -f ${tmpfile} -l "app=${appLabel}" --prune
  • Where tmpfile contains the value of configuration
• if waitForRollout is true:
  • if rolloutSelector is not provided:
    • Executes oc rollout status ${rolloutKind}/${appLabel}
  • else
    • Executes oc rollout status ${rolloutKind}/${object} for every rolloutKind object matched by rolloutSelector

OC Install check und Rollout abgdeckt durch #42

Andere Testfälle ev. durch einen System Test abdecken
