I want to run the tests related to this project on github, see folder test on https://github.com/node-opcua/node-opcua . Unfortunately I have no idea which testing framework was used and how to run all the tests?
First, run npm install
This will install the required dependencies.
You can then use
npm test
See here: https://github.com/node-opcua/node-opcua/blob/master/package.json#L15
That will run the tests using Mocha.
