How to run the tests in bitcore-node?

I am trying to run the tests in bitcore-node but am not being successful.

Can you please outline the steps I need to go through to see the tests run.

After running npm install I try running mocha at the command line but see this error message.

Error: Could not locate the bindings file. Tried:

Thanks for your help,

You may need to run node-gyp -d rebuild

Also note: if you want to run the tests in integration/regtest.js, you’ll need to recompile bitcoin and the bindings with an environment variable set: export BITCORENODE_ENV=test.
