## Introduction ##
This dir contains most scripts needed for the auto-test environment. There are scripts with functions to adapt to the apis of the components of the Non-RT RIC; Policy Agent, A1 Controller and Ric (A1) simulator.
Some of the scripts can also be used for other kinds of tests, for example basic tests.

## Overview for common test scripts and files ##

`test_env.sh` \
Common env variables for test in the auto-test dir. All configuration of port numbers, image names and version etc shall be made in this file.
Used by the auto test scripts/suites but could be used for other test script as well.

`testcase_common.sh` \
Common functions for auto test cases in the auto-test dir. This script is the foundation of test auto environment which sets up images and enviroment variables needed by this script as well as the script adapting to the APIs.
The included functions are described in detail further below.

`testsuite_common.sh` \
Common functions for running two or more auto test scripts as a suite.

`agent_api_functions.sh` \
Contains functions for adapting towards the Policy Agent API, also via dmaap (using a message-router stub interface)

`controller_api_functions.sh` \
Contains functions for adaping towards the A1-controller API.

`ricsimulator_api_functions.sh` \
Contains functions for adapting towards the RIC (A1) simulator admin API.

`compare_json.py` \
A python script to compare two json obects for equality. Note that the comparsion always sort json-arrays before comparing (that is, it does not care about the order of items within the array). In addition, the target json object may specify individual parameter values where equality is 'dont care'.

`count_json_elements.py` \
A python script returning the number of items in a json array.

`create_policies_process.py` \
A python script to create a batch of policies. The script is intended to run in a number of processes to create policies in parallel.

`create_rics_json.py` \
A python script to create a json file from a formatted string of ric info. Helper for the test enviroment.

`delete_policies_process.py` \
A python script to delete a batch of policies. The script is intended to run in a number of processes to delete policies in parallel.

`extract_sdnc_reply.py` \
A python script to extract the information from an sdnc (A1 Controller) reply json. Helper for the test environment.

`do_curl_function.sh`
A script for executing a curl call with a specific url and optional payload. It also compare the response with an expected result in terms of response code and optional returned payload. Intended to be used by test script (for example basic test scripts of other components)



### Descriptions of functions in testcase_common.sh ###

#### Script args ####
The script can be started with these arguments

| arg list |
|--|
| `local|remote|remote-remove [auto-clean] [--stop-at-error] [--use-local-image <app-nam> [<app-name>]*]` |

| parameter | description |

| `--stop-at-error` | intended for debugging and make the script stop at first 'FAIL' and save all logs with a prefix 'STOP_AT_ERROR' |
| `--use-local-image` | Only applicable when running as 'remote' or 'remote-remove'.
