Michael Schmoock 43b5abeb22 fix: pip dependency version for psycopg2-binary 
Trying to `pip install psycopg2-binary==2.8.3` raised an error for a
long time. Since version `2.8.4` is recent and also seem to work I
suggest updating the requirements so other users dont run into the
following error, where pip tries to use `pg_config` for the BINARY
package:

Collecting psycopg2-binary==2.8.3 (from -r contrib/pyln-testing/requirements.txt (line 6))

    Error: pg_config executable not found.

    pg_config is required to build psycopg2 from source.  Please add the directory
    containing pg_config to the $PATH or specify the full executable path with the
    option:

        python setup.py build_ext --pg-config /path/to/pg_config build ...

    or with the pg_config option in 'setup.cfg'.

    If you prefer to avoid building psycopg2 from source, please install the PyPI
    'psycopg2-binary' package instead.

    For further information please check the 'doc/src/install.rst' file (also at
    <http://initd.org/psycopg/docs/install.html>).

README.md

pyln-testing: A library to write tests against c-lightning

This library implements a number of utilities that help building tests for c-lightning nodes. In particular it provides a number of pytest fixtures that allow the management of a test network of a given topology and then execute a test scenarion.

pyln-testing is used by c-lightning for its internal tests, and by the community plugin directory to exercise the plugins.

Installation

pyln-testing is available on pip:

pip install pyln-testing

Alternatively you can also install the development version to get access to currently unreleased features by checking out the c-lightning source code and installing into your python3 environment:

git clone https://github.com/ElementsProject/lightning.git
cd lightning/contrib/pyln-testing
python3 setup.py develop

This will add links to the library into your environment so changing the checked out source code will also result in the environment picking up these changes. Notice however that unreleased versions may change API without warning, so test thoroughly with the released version.
