Scala Hyperledger API - Running Tests locally using the Production Network

Prerequisites

Have a working UC4-chaincode-network running (Checkout the hlf-network or alternatively fetch the latest network by executing sh ./fetch_prod_network.sh )
- Have faketime installed
```
sudo apt-get install faketime
```
- Start the network by executing
```
./restart.sh -t
```
of the hlf-network.
Note: use the testing flag to have the network create the testing identities.
Set up the Environment Variables: The necessary variables with their concrete values which need to be exported are provided at the end of the output of the network start script. They look similar to these:
- find the Certificate Authority
```
export UC4_KIND_NODE_IP=172.17.0.2
```
- referencing the "connection_profile.yaml"
```
export UC4_CONNECTION_PROFILE=/tmp/hyperledger/connection_profile_kubernetes_local.yaml
```
- describing what kind of Network you are using
```
export UC4_TESTBASE_TARGET=PRODUCTION_NETWORK
```
The given three export lines can simply be copied to the command line.

Run the Tests :)

Run the tests from the hlf-api directory using: sbt clean compile testOnly "*ApprovalTests *CertificateErrorTests"

Troubleshooting:

Without sbt clean, tests might fail without obvious reasons.
