## Getting Started

**QConnectBaseLibrary** is a connection testing library for [Robot
Framework](https://robotframework.org). Library will be supported to
downloaded from PyPI soon. It provides a mechanism to handle trace log
continously receiving from a connection (such as Raw TCP, SSH, Serial,
etc.) besides sending data back to the other side. It's especially
efficient for monitoring the overflood response trace log from an
asynchronous trace systems. It is supporting Python 3.7+ and
RobotFramework 3.2+.

### How to install

**QConnectBaseLibrary** can be installed in two different ways.

1.  Installation via PyPi (recommended for users)

    ``` 
    pip install robotframework-qconnect-base
    ```

    [QConnectBaseLibrary in
    PyPi](https://pypi.org/project/robotframework-qconnect-base/)

2.  Installation via GitHub (recommended for developers)

    -   Clone the **robotframework-qconnect-base** repository to your
        machine.

        ``` 
        git clone https://github.com/test-fullautomation/robotframework-qconnect-base.git
        ```

        [QConnectBaseLibrary in
        GitHub](https://github.com/test-fullautomation/robotframework-qconnect-base)

    -   Install dependencies

        **QConnectBaseLibrary** requires some additional Python
        libraries. Before you install the cloned repository sources you
        have to install the dependencies manually. The names of all
        related packages you can find in the file `requirements.txt` in
        the repository root folder. Use pip to install them:

        ``` 
        pip install -r ./requirements.txt
        ```

        Additionally install **LaTeX** (recommended: TeX Live). This is
        used to render the documentation.

    -   Configure dependencies

        The installation of **QConnectBaseLibrary** includes to generate
        the documentation in PDF format. This is done by an application
        called **GenPackageDoc**, that is part of the installation
        dependencies (see `requirements.txt`).

        **GenPackageDoc** uses **LaTeX** to generate the documentation
        in PDF format. Therefore **GenPackageDoc** needs to know where
        to find **LaTeX**. This is defined in the **GenPackageDoc**
        configuration file

        ``` 
        packagedoc\packagedoc_config.json
        ```

        Before you start the installation you have to introduce the
        following environment variable, that is used in
        `packagedoc_config.json`:

        -   `GENDOC_LATEXPATH` : path to `pdflatex` executable

    -   Use the following command to install **QConnectBaseLibrary**:

        ``` 
        python setup.py install
        ```

## Usage

QConnectBase Library support following keywords for testing connection
in RobotFramework.

### **connect**

## Contribution Guidelines

QConnectBaseLibrary is designed for ease of making an extension library.
By that way you can take advantage of the QConnectBaseLibrary's
infrastructure for handling your own connection protocal. For creating
an extension library for QConnectBaseLibrary, please following below
steps.

1.  Create a library package which have the prefix name is
    **robotframework-qconnect-***\[your specific name\]*.
2.  Your hadling connection class should be derived from
    **QConnectBase.connection_base.ConnectionBase** class.
3.  In your *Connection Class*, override below attributes and methods:

> -   **\_CONNECTION_TYPE**: name of your connection type. It will be
>     the input of the conn_type argument when using **connect**
>     keyword. Depend on the type name, the library will detemine the
>     correct connection handling class.
> -   **\_\_init\_\_(self, \_mode, config)**: in this constructor
>     method, you should:
>
> > -   Prepare resource for your connection.
> >
> > -   Initialize receiver thread by calling
> >     **self.\_init_thread_receiver(cls.\_socket_instance,
> >     mode=\"\")** method.
> >
> > -   Configure and initialize the lowlevel receiver thread (if it's
> >     necessary) as below
> >
> >         self._llrecv_thrd_obj = None
> >         self._llrecv_thrd_term = threading.Event()
> >         self._init_thrd_llrecv(cls._socket_instance)
> >
> > -   Incase you use the lowlevel receiver thread. You should
> >     implement the **thrd_llrecv_from_connection_interface()**
> >     method. This method is a mediate layer which will receive the
> >     data from connection at the very beginning, do some process then
> >     put them in a queue for the **receiver thread** above getting
> >     later.
> >
> > -   Create the queue for this connection (use Queue.Queue).
>
> -   **connect()**: implement the way you use to make your own
>     connection protocol.
> -   **\_read()**: implement the way to receive data from connection.
> -   **\_write()**: implement the way to send data via connection.
> -   **disconnect()**: implement the way you use to disconnect your own
>     connection protocol.
> -   **quit()**: implement the way you use to quit connection and clean
>     resource.

## Configure Git and correct EOL handling

Here you can find the references for [Dealing with line
endings](https://help.github.com/articles/dealing-with-line-endings/).

Every time you press return on your keyboard you're actually inserting
an invisible character called a line ending. Historically, different
operating systems have handled line endings differently. When you view
changes in a file, Git handles line endings in its own way. Since you're
collaborating on projects with Git and GitHub, Git might produce
unexpected results if, for example, you're working on a Windows machine,
and your collaborator has made a change in OS X.

To avoid problems in your diffs, you can configure Git to properly
handle line endings. If you are storing the .gitattributes file directly
inside of your repository, than you can asure that all EOL are manged by
git correctly as defined.

## Sourcecode Documentation

For investigating sourcecode, please refer to [QConnectBase library
documentation](docs/html/index.html)

A detailed documentation of the QConnectBase package can also be found
here:
[QConnectBase.pdf](https://github.com/test-fullautomation/robotframework-qconnect-base/blob/develop/QConnectBase/QConnectBase.pdf)

## Feedback

If you have any problem when using the library or think there is a
better solution for any part of the library, I'd love to know it, as
this will all help me to improve the library. Please don\'t hesitate to
contact me.

Do share your valuable opinion, I appreciate your honest feedback!
