# ct_os_test_template_app IMAGE APP IMAGE_IN_TEMPLATE EXPECTED_OUTPUT [PORT, PROTOCOL, RESPONSE_CODE, OC_ARGS, ... ]
# --------------------
# Runs [image] and [app] in the openshift and optionally specifies env_params
# as environment variables to the image. Then check the http response.
# Arguments: image_name - prefix or whole ID of the pod to run the cmd in (compulsory)
# Arguments: template - url or local path to a template to use (compulsory)
# Arguments: name_in_template - image name used in the template
# Arguments: expected_output - PCRE regular expression that must match the response body (compulsory)
# Arguments: port - which port to use (optional; default: 8080)
# Arguments: protocol - which protocol to use (optional; default: http)
# Arguments: response_code - what http response code to expect (optional; default: 200)
# Arguments: oc_args - all other arguments are used as additional parameters for the `oc new-app`
# command, typically environment variables (optional)
# Arguments: other_images - some templates need other image to be pushed into the OpenShift registry,
# specify them in this parameter as "<image>|<tag>", where "<image>" is a full image name
# (including registry if needed) and "<tag>" is a tag under which the image should be available
# in the OpenShift registry.
