Strategy:
34 1 Tom Clegg
# Install your local (possibly modified) client library to a virtualenv
35 1 Tom Clegg
# Run the client library test suite
36 3 Tom Clegg
# Build a client library package and install it to the virtualenv
37 1 Tom Clegg
# Install your local (possibly modified) FUSE driver to the same virtualenv
38 1 Tom Clegg
# Run the FUSE driver test suite
39 3 Tom Clegg
# Build a FUSE driver package and install it to the virtualenv

Note: The test suite brings up a Keep server and an API server to run tests against. For best results:
42 2 Tom Clegg
* Try [[Hacking Keep]] and [[Hacking API Server]] to make sure you have all the right dependencies for running the Keep and API servers.
43 2 Tom Clegg
* Make sure you have a blob_signing_key in services/api/config/application.yml
