This 'fixes' the `wait_for` helper by removing a pointless final `time.sleep()`, thus potentially making the method return quicker. The old code could have had three final states: - success() := True - Timeout and success() := True - Timeout and success() := False The new code has just two final state: - success() := True - Timeout and success() := False It ensures the final `time.sleep()` is just the right amount before timeout. And more importantly making it more readable :-) Changelog-None
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.
