The FUSE driver requires associated libraries to build:

<pre>
10 5 Tom Clegg
sudo apt-get install libattr1-dev libfuse-dev pkg-config fuse
11 5 Tom Clegg
sudo adduser "$USER" fuse
12 5 Tom Clegg
sudo chmod g+rw /dev/fuse
13 5 Tom Clegg
sudo chown root:fuse /dev/fuse

</pre>

After installing @fuse@ and adding yourself to the @fuse@ group, you need to start a new login session. Make sure the @groups@ command reports that you're in the @fuse@ group.

h2. virtualenv
26 6 Brett Smith
27 6 Brett Smith
virtualenv helps you isolate the dependencies for a specific package or environment, much like Bundler does for our Rails applications.  The recommended way to deploy is to build a virtualenv for Arvados development.

To build the virtualenv, run:
30 6 Brett Smith
31 6 Brett Smith
<pre>
32 6 Brett Smith
$ virtualenv --setuptools VENVDIR
33 6 Brett Smith
</pre>
34 6 Brett Smith
35 6 Brett Smith
(@VENVDIR@ can be a directory anywhere you like, although best practice is to keep it outside your source directory.)
36 6 Brett Smith
37 6 Brett Smith
To set up the shell to use the isolated virtualenv environment, run:
38 6 Brett Smith
39 6 Brett Smith
<pre>
40 6 Brett Smith
$ source VENVDIR/bin/activate
41 6 Brett Smith
</pre>

To learn more about using and configuring virtualenv, read the "virtualenv usage documentation":https://virtualenv.pypa.io/en/latest/virtualenv.html#usage.

h2. Run tests

Strategy:
48 6 Brett Smith
# Set up the environment to use a dedicated virtualenv
49 1 Tom Clegg
# Run the client library test suite
50 1 Tom Clegg
# Build a client library package and install it to the virtualenv
51 1 Tom Clegg
# Run the FUSE driver test suite
52 1 Tom Clegg
# Build a FUSE driver package and install it to the virtualenv
53 1 Tom Clegg
54 1 Tom Clegg
Note: The test suite brings up a Keep server and an API server to run tests against. For best results:
55 1 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.
56 1 Tom Clegg
* Make sure you have a blob_signing_key in services/api/config/application.yml
