h1. Hacking prerequisites
The Arvados test suite can run in a Docker container, a VM, or your workstation -- provided a few prerequisites are satisfied.
h2. Host options
h3. Starting on your workstation
If your workstation is a debian stretch jessie system -- and you don't mind installing a bunch of packages on your workstation, some of them without apt -- the easiest way to get running is to run tests on bare metal. Skip to "Dependencies".
Other linux distributions should work too with some modifications, but it's probably easier to use a VM.
h3. Starting on a VM
Another option is to create a virtual machine using something like Xen or VirtualBox, and run debian stretch jessie on it. The instructions below assume you have just a few basic requirements:
* SSH server
* sudo (@apt-get install sudo@)
* A user account with sudo privileges
h3. Starting in a docker container
This can get you started quickly, but (unlike the above options) you'll need to remember to use something like @docker commit@ to save your state before shutting down your container.
See http://docker.io for more about installing docker. On debian it looks something like this.
<pre>
echo 'deb http://http.debian.net/debian jessie-backports main' | sudo tee -a /etc/apt/sources.list.d/jessie-backports.list
sudo apt-get install docker-ce docker.io
sudo adduser $USER docker
# {log out & log back in}
groups
# {should include "docker"}
</pre>
Start up a new container with debian 9 (stretch), make a new user and log in as that user:
<pre>
docker run -it --privileged debian:9 bash
apt-get update
apt-get -y install sudo
adduser me
adduser me sudo
sudo -u me -i
</pre>
The "--privileged" is required in order for /dev/fuse to be accessible (without it, no tests that require FUSE will work).
h2. Install dev environment
<pre>
# only on debian 9 (stretch), to permit ruby 2.3 compilation (see https://github.com/rbenv/ruby-build/wiki#openssl-usrincludeopensslasn1_mach102-error-error-this-file-is-obsolete-please-update-your-software):

h2. Get the arvados source tree and test scripts
<pre>
cd
git clone https://github.com/curoverse/arvados.git
</pre>
...or, if you're a committer with your public key on our git server:
<pre>
cd
git clone git@git.curoverse.com:arvados.git
</pre>
h2. Start Postgres
_If you're running in a docker container_ you'll need to start Postgres manually:
<pre>
sudo /etc/init.d/postgresql start
</pre>
(If you're on a regular workstation/server/VM, startup scripts have already taken care of that for you.)
h2. Ensure entropy
If you're running in a VM, you might run out of entropy, which will make some tests run very slowly. The easiest solution is to install haveged.
<pre>
sudo apt-get install haveged
</pre>
h2. Setup groups
Make sure the fuse and docker groups exist (create them if necessary) and that the user who will run the tests is a member of them.
h2. Create a Postgres user
Create an "arvados" user with "create database" privileges. The test suite will create and drop the arvados_test database as needed.
<pre>
newpw=`tr -cd a-zA-Z </dev/urandom |head -c32`
sudo -u postgres psql -c "create user arvados with createdb encrypted password '$newpw'"
cp -i ~/arvados/services/api/config/database.yml{.example,}
newpw="$newpw" perl -pi~ -e 's/xxxxxxxx/$ENV{newpw}/' ~/arvados/services/api/config/database.yml
</pre>
h2. Run tests
<pre>
time ~/arvados/build/run-tests.sh WORKSPACE=~/arvados
</pre>
During development, you'll probably want something more like this. It reuses the given temp directory, which avoids a lot of repetitive downloading of dependencies, and allows you to save time with @--skip-install@ or @--only-install sdk/ruby@ and so on.
<pre>
mkdir -p ~/.cache/arvados-build
time ~/arvados/build/run-tests.sh WORKSPACE=~/arvados --temp ~/.cache/arvados-build
</pre>
