Running tests¶
- Table of contents
- 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 == Test targets: cmd/arvados-client lib/dispatchcloud/container sdk/go/auth sdk/pam:py3 services/fuse tools/crunchstat-summary cmd/arvados-server lib/dispatchcloud/scheduler sdk/go/blockdigest sdk/python services/fuse:py3 tools/crunchstat-summary:py3 lib/cli lib/dispatchcloud/ssh_executor sdk/go/crunchrunner sdk/python:py3 services/health tools/keep-block-check lib/cloud lib/dispatchcloud/worker sdk/go/dispatch services/arv-git-httpd services/keep-balance tools/keep-exercise lib/cloud/azure lib/service sdk/go/health services/crunch-dispatch-local services/keepproxy tools/keep-rsync lib/cloud/ec2 sdk/cwl sdk/go/httpserver services/crunch-dispatch-slurm services/keepstore tools/sync-groups lib/cmd sdk/cwl:py3 sdk/go/keepclient services/crunch-run services/keep-web lib/controller sdk/go/arvados sdk/go/manifest services/crunchstat services/nodemanager lib/crunchstat sdk/go/arvadosclient sdk/go/stats services/dockercleaner services/nodemanager:py3 lib/dispatchcloud sdk/go/asyncbuf sdk/pam services/dockercleaner:py3 services/ws What next?
Example: testing lib/dispatchcloud/container, showing verbose/debug logs:
What next? test lib/dispatchcloud/container/ -check.vv ======= test lib/dispatchcloud/container START: queue_test.go:99: IntegrationSuite.TestCancelIfNoInstanceType WARN[0000] cancel container with no suitable instance type ContainerUUID=zzzzz-dz642-queuedcontainer error="no suitable instance type" WARN[0000] cancel container with no suitable instance type ContainerUUID=zzzzz-dz642-queuedcontainer error="no suitable instance type" START: queue_test.go:37: IntegrationSuite.TearDownTest PASS: queue_test.go:37: IntegrationSuite.TearDownTest 0.846s PASS: queue_test.go:99: IntegrationSuite.TestCancelIfNoInstanceType 0.223s START: queue_test.go:42: IntegrationSuite.TestGetLockUnlockCancel INFO[0001] adding container to queue ContainerUUID=zzzzz-dz642-queuedcontainer InstanceType=testType Priority=1 State=Queued START: queue_test.go:37: IntegrationSuite.TearDownTest PASS: queue_test.go:37: IntegrationSuite.TearDownTest 0.901s PASS: queue_test.go:42: IntegrationSuite.TestGetLockUnlockCancel 0.177s OK: 2 passed PASS ok git.arvados.org/arvados.git/lib/dispatchcloud/container 2.150s ======= test lib/dispatchcloud/container -- 3s Pass: lib/dispatchcloud/container tests (3s) All test suites passed.
Running individual test cases¶
Golang¶
Most Go packages use gocheck. Use gocheck command line args like -check.f.
What next? test lib/dispatchcloud/container -check.vv -check.f=LockUnlock ======= test lib/dispatchcloud/container START: queue_test.go:42: IntegrationSuite.TestGetLockUnlockCancel INFO[0000] adding container to queue ContainerUUID=zzzzz-dz642-queuedcontainer InstanceType=testType Priority=1 State=Queued START: queue_test.go:37: IntegrationSuite.TearDownTest PASS: queue_test.go:37: IntegrationSuite.TearDownTest 0.812s PASS: queue_test.go:42: IntegrationSuite.TestGetLockUnlockCancel 0.184s OK: 1 passed PASS ok git.arvados.org/arvados.git/lib/dispatchcloud/container 1.000s ======= test lib/dispatchcloud/container -- 2s
Python¶
If what you really want to do is focus on failing or newly-added tests, consider passing the appropriate switches to do that:
-x, --exitfirst Exit instantly on first error or failed test
--lf, --last-failed Rerun only the tests that failed at the last run (or
all if none failed)
--ff, --failed-first Run all tests, but run the last failures first. This
may re-order tests and thus lead to repeated fixture
setup/teardown.
--nf, --new-first Run tests from new files first, then the rest of the
tests sorted by file mtime
If you want to manually select tests:
FILENAME Run tests from FILENAME, relative to the source root
FILENAME::CLASSNAME Run tests from CLASSNAME
FILENAME::FUNCNAME, FILENAME::CLASSNAME::FUNCNAME
Run only the named test function
-k EXPRESSION Only run tests which match the given substring
expression. An expression is a Python evaluable
expression where all names are substring-matched
against test names and their parent classes.
Example: -k 'test_method or test_other' matches all
test functions and classes whose name contains
'test_method' or 'test_other', while -k 'not
test_method' matches those that don't contain
'test_method' in their names. -k 'not test_method
and not test_other' will eliminate the matches.
Additionally keywords are matched to classes and
functions containing extra names in their
'extra_keyword_matches' set, as well as functions
which have names assigned directly to them. The
matching is case-insensitive.
-m MARKEXPR Only run tests matching given mark expression. For
example: -m 'mark1 and not mark2'.
For even more options, refer to the pytest command line reference.
Example:
What next? test sdk/python:py3 --disable-warnings --tb=no --no-showlocals tests/test_keep_client.py::KeepDiskCacheTestCase ======= test sdk/python […pip output…] ========================================================== test session starts ========================================================== platform linux -- Python 3.8.19, pytest-8.2.0, pluggy-1.5.0 rootdir: /home/brett/Curii/arvados/sdk/python configfile: pytest.ini collected 9 items tests/test_keep_client.py F........

RailsAPI¶
What next? test services/api TESTOPTS=--name=/.*signed.locators.*/ [...] # Running: .... Finished in 1.080084s, 3.7034 runs/s, 461.0751 assertions/s.
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 $ARVADOS_HOME RAILS_ENV=diagnostics bundle exec rake TEST=test/diagnostics/pipeline_test.rb
Running workbench2 tests¶
React uses a lot of filesystem watchers (via inotify). The default number of watched files is relatively low at 8192. Increase that with:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -pDocker¶
The integration tests can be run on non-debian based systems using docker. The workbench2 repo includes a Dockerfile that preinstalls the necessary dependencies to run cypress.
Build the docker image using this command from within the arvados repository
docker build . -f services/workbench2/docker/Dockerfile -t workbench2-build
Then, start the container using the following arguments:
xhost +local:root ARVADOS_DIR=/path/to/arvados docker run -ti -v$ARVADOS_DIR:/usr/src/arvados -w /usr/src/arvados --env="DISPLAY" --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" workbench2-build:latest bash
Docker Troubleshooting¶
No version of Cypress is installed¶
Solution: Manually install the required cypress version by running ./node_modules/.bin/cypress install inside the container
Debian Host System¶
These instructions assume a Debian 10 (buster) host system.
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 --no-install-recommends yarn libgbm-dev # we need the correct version of node to install cypress # use arvados-server install to get it (and all other dependencies) # All this will then not need to be repeated by ./tools/run-integration-tests.sh # so we are not doing double work. cd /usr/src/arvados go mod download cd cmd/arvados-server go install ~/go/bin/arvados-server install -type test cd <your-wb2-directory> yarn run cypress install
Make sure you have both the arvados and arvados-workbench2 source trees available, and then use the following commands (adjust path for the arvados source tree, if necessary) from your workbench2 source tree.
Running Tests¶
Run the unit tests with:
make unit-tests # or yarn test
Run the cypress integration tests with:
./tools/run-integration-tests.sh -i -a /usr/src/arvados
