Running tests

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.

Background

You have the arvados source tree at ~/arvados and you might have local modifications.

Install prerequisites

Follow instructions at Hacking prerequisites: "Install dev environment", etc. Don't miss creating the Postgres database, docker groups, etc.

Environment

Your locale must use utf-8. Set environment variable LANG=C.UTF-8 if necessary to ensure the "locale" command reports UTF-8.

If you're Jenkins

Run all tests from a clean slate (slow, but more immune to leaks)

~/arvados/build/run-tests.sh WORKSPACE=~/arvados

If you're a developer

Cache everything needed to run test suites:

mkdir ~/.cache/arvados-build
~/arvados/build/run-tests.sh WORKSPACE=~/arvados --temp ~/.cache/arvados-build --only install

Start interactive mode:

$ ~/arvados/build/run-tests.sh WORKSPACE=~/arvados --temp ~/.cache/arvados-build --interactive

Start interactive mode and enabled debug output:

$ ~/arvados/build/run-tests.sh WORKSPACE=~/arvados ARVADOS_DEBUG=1 --temp ~/.cache/arvados-build --interactive

When prompted, choose a test suite to run:

== 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

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:

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

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.

Controlling test order (Rails)

Rails tests start off with a line like this

Run options: -v -d --seed 57089

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:

What next? test services/api TESTOPTS="-v -d --seed 57089"

Other options

For more usage info, try:

~/arvados/build/run-tests.sh --help

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.

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

You can now run the "qr1hi" diagnostics tests using the following command:

  cd $ARVADOS_HOME
  RAILS_ENV=diagnostics bundle exec rake TEST=test/diagnostics/pipeline_test.rb

Running workbench2 tests

These instructions assume a Debian 10 (buster) host system. It is also possible to run the tests in a docker container, which you should start with these arguments:

xhost +local:root
ARVADOS_DIR=/path/to/arvados
docker run -ti -v$PWD:$PWD -v$ARVADOS_DIR:/usr/src/arvados -w$PWD --env="DISPLAY" --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" bash

If you use docker, the rest of the instructions should be executed inside the container.

Install the Arvados test dependencies:

echo "deb http://deb.debian.org/debian buster-backports main" > /etc/apt/sources.list.d/backports.list
apt-get update
apt-get install -y --no-install-recommends golang -t buster-backports
apt-get install -y --no-install-recommends build-essential ca-certificates git libpam0g-dev

Install a few more dependencies for workbench2:

apt-get update
apt-get install -y --no-install-recommends gnupg2 sudo curl
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
apt-get update
apt-get install -y --install-recommends yarn
yarn run cypress install

Make sure you have both the arvados and arvados-workbench2 source trees available, and then run a command like this (adjust path for the arvados source tree, if necessary) from your workbench2 source tree:

./tools/run-integration-tests.sh -i -a /usr/src/arvados
