Arvados

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

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>
