h1. Running tests
{{toc}}
The arvados git repository has a @run-tests.sh@ script which tests (nearly) all of the components in the source tree. Jenkins at https://ci.arvados.org uses this exact script, so running it _before pushing a new master_ is a good way to predict whether Jenkins will fail your build and start pestering you by IRC.
h2. Background
You have the arvados source tree at @~/arvados@ and you might have local modifications.
h2. Install prerequisites
Follow instructions at [[Hacking prerequisites]]: "Install dev environment", etc. Don't miss creating the Postgres database, docker groups, etc.
h2. Environment
Your locale must use utf-8. Set environment variable LANG=C.UTF-8 if necessary to ensure the "locale" command reports UTF-8.
h2. If you're Jenkins
Run all tests from a clean slate (slow, but more immune to leaks)
<pre>
~/arvados/build/run-tests.sh WORKSPACE=~/arvados
</pre>
h2. If you're a developer
Cache everything needed to run test suites:
<pre>
mkdir ~/.cache/arvados-build
~/arvados/build/run-tests.sh WORKSPACE=~/arvados --temp ~/.cache/arvados-build --only install
</pre>
Start interactive mode:
<pre>
$ ~/arvados/build/run-tests.sh WORKSPACE=~/arvados --temp ~/.cache/arvados-build --interactive
</pre>
Start interactive mode and enabled debug output:
<pre>
$ ~/arvados/build/run-tests.sh WORKSPACE=~/arvados ARVADOS_DEBUG=1 --temp ~/.cache/arvados-build --interactive
</pre>
When prompted, choose a test suite to run:
<pre>
== Interactive commands:
test TARGET
test TARGET:py3 (test with python3)
test TARGET -check.vv (pass arguments to test)
install TARGET
install env (go/python libs)
install deps (go/python libs + arvados components needed for integration tests)
reset (...services used by integration tests)
exit

Example: testing lib/dispatchcloud/container, showing verbose/debug logs:
<pre>
What next? test lib/dispatchcloud/container/ -check.vv

h3. Running individual test cases
Most Go packages use gocheck. Use gocheck command line args like -check.f.
<pre>
What next? test lib/dispatchcloud/container -check.vv -check.f=LockUnlock
======= test lib/dispatchcloud/container

h3. Restarting services for integration tests
If you have changed services/api code, and you want to check whether it breaks the lib/dispatchcloud/container integration tests:
<pre>
What next? reset # teardown the integration-testing environment
What next? install services/api # (only needed if you've updated dependencies)
What next? test lib/dispatchcloud/container # bring up the integration-testing environment and run tests
What next? test lib/dispatchcloud/container # leave the integration-testing environment up and run tests
</pre>
h3. Updating cache after pulling master
Always quit interactive mode and restart after modifying run-tests.sh (via git-pull, git-checkout, editing, etc).
When you start, run "install all" to get the latest gem/python dependencies, install updated versions of Arvados services used by integration tests, etc.
Then you can resume your cycle of "test lib/controller", etc.
h3. Controlling test order (Rails)
Rails tests start off with a line like this
<pre>
Run options: -v -d --seed 57089
</pre>
The seed value determines the order tests are run. To reproduce reproduce an order-dependent test failure, specify the same seed as a previous failed run:
<pre>
What next? test services/api TESTOPTS="-v -d --seed 57089"
</pre>
h3. Other options
For more usage info, try:
<pre>
~/arvados/build/run-tests.sh --help
</pre>
h2. Running workbench diagnostics tests
You can run workbench diagnostics tests against any production server.
Update your workbench application.yml to add a "diagnostics" section with the login token and pipeline details. The below example configuration is to run the "qr1hi-p5p6p-ftcb0o61u4yd2zr" pipeline in "qr1hi" environment.
<pre>
diagnostics:
secret_token: useanicelongrandomlygeneratedsecrettokenstring
arvados_workbench_url: https://workbench.qr1hi.arvadosapi.com
user_tokens:
active: yourcurrenttokenintheenvironmenttowhichyouarepointing
pipelines_to_test:
pipeline_1:
template_uuid: qr1hi-p5p6p-ftcb0o61u4yd2zr
input_paths: []
max_wait_seconds: 300
</pre>
You can now run the "qr1hi" diagnostics tests using the following command:
<pre>
cd $ARVADOS_HOME
RAILS_ENV=diagnostics bundle exec rake TEST=test/diagnostics/pipeline_test.rb
</pre>
