## Download required libraries

This projects requires the LibCommon and LibIts libraries to compile. The libraries location are git submodules of the current repository.

Once you have cloned the present repository, in order to install the libraries you want to execute:

    git submodule init
    git submodule update

Alternatively, you may clone the project together with the required libraries with the following command:

    git clone --recurse-submodules <URL to the repository>

## Installation

The MEC Testing Framework project builds and tests regularly on the following platforms:

  - Linux (Ubuntu)

Note: The [OpenSSL](https://www.openssl.org) version > 1.1.x is also required.

### How to do it?

They are two different methods:
- Using [Vagrant](https://www.vagrantup.com/)
- Using [Docker](https://www.docker.com/)

How to choose one of these methods is depending of your host system.

NOTE: In all case, if you want to setup an continuous integration process (e.g. Jenkins), Docker is the best choice. 


#### The host system is Windows
The both methods require a virtual machine. You can use either VirtualBox or WMware.
In this case, the easiest way is to use Vagrant.


#### The host system is Linux
Vagrant requires a virtual machine. You can use either VirtualBox or WMware.
Docker does not need a virtual machine, so it is the more efficant way.


### Using Vagrant

Pre-requisites on your host machine:
- Install [Virtualbox](https://www.virtualbox.org/manual/ch01.html)
- Install [Vagrant](https://www.vagrantup.com/intro/getting-started/)
- Install Vagrant plugin vagrant-vbguest
- Credentials to access [ETSI forge](https://forge.etsi.org/gitlab/users/sign_in)
    - Set the environment variable USERNAME to your ETSI EOL account user name
    - Set the environment variable PASSWORD to your ETSI EOL account password

Procedure:
- On your host machine, open a command line session (PuTTY, DOS window...)
- From the ETSI MEC Testing Framework project, clone the Vagrant folder
- In the file Vagrantfile, modify the tag config.vm.provision replacing <username> & <password> strings by your ETSI credentials
- In the Vagrant folder, execute the following commands:

```sh
$ vagrant up --provider virtualbox --provision
...
```

NOTE The creation and the installations will take some time to achieve
- Stop vagrant virtual machine

```sh
$ vagrant halt
...
```

- Update the file 'Vagrantfile' to match with your networks configuration
- Re-start the vagrant virtual machine and log to to the machine

```sh
$ vagrant up
...
$ vagrant ssh
```

- Switch to the next clause (Usage)

NOTE The user password is vagrant.


### Using Docker

Pre-requisites on your host machine:
- Install Virtualbox
- Install Docker

Procedure for a Windows host machine:
- On your host machine, open a the Docker Quickstart Terminal
- On your host machine, clone the ETSI MEC Testing Framework project. NOTE that only Docker folder and .jenkins.sh script file are required
- From the ETSI MEC Testing Framework project root directory, execute the following commands:

```sh
$ ./.jenkins.sh
...
```

NOTE The creation and the installations will take some time to achieve
- Start the container

```sh
$ ./docker/run-container.sh
...
```

- Switch to the next clause (Usage)


### From scratch

Pre-requisites:
- Install Virtualbox

Procedure:

- In your home directory, create the following folders: 
    - $HOME/frameworks, 
    - $HOME/dev
    - $HOME/lib
- In $HOME/frameworks, build the following package:
    - asn1c, according the procedure specified [here](https://github.com/vlm/asn1c.git)
    - Eclipse IDE for C/C++ Developers, according the procedure specified [here](https://www.eclipse.org/cdt/)

    - Import the TITAN plugin into your Eclipse IDE, according the procedure specified [here](https://github.com/eclipse/titan.core)
- Clone the ETSI MEC Testing Framework project into $HOME/dev folder

```sh
$ git clone 
```

- Update your default environment with the content of the script $HOME/dev/STF569_Mec/scripts/devenv.bash.ubuntu
- Switch to the next clause (Usage)


## Usage

This clause describes how to compile and execute an Abstract Test Suite.


Pre-requisites:
- Your machine is installed following one of the installation method describes in the previous clause
- Your are logged as 'etsi' or 'vagrant' user

Procedure using Eclipse TITAN:
- Start eclipse using a new workspace, (e.g. with the name workspace_titan)
- Download and follow the steps to install Eclipse plugins for TITAN, accessible [here]{https://www.eclipse.org/downloads/download.php?file=/titan/Eclipse_installationguide.pdf}
- Open the workspace_titan
- Create a new TITAN project (e.g. STF569_Mec)
<TODO>

Procedure in TITAN command line:
- Open several SSH session (PuTTY...)
- Change to the directory ~/dev/STF569_Mec/src/AtsMec/objs
- Build the test suite AtsMec

```sh
$ ../bin/mec_generate_makefile.bash
...
```

- Edit the file ../etc/AtsMec.cfg
- Update the following fields:
    - PICS_HEADER_HOST, the HTTP host header value
    - system.httpPort.params
- To run the test suite, execute the following command:

```sh
$ ../bin/run-all.bash
...
```

- The log files are located in ../logs folder. You can edit them using any editor or using the Eclipse TITAN log plugins
