----------------------------------
Summary: Support multi-container robot test execution
Key: HDDS-1424
URL: https://issues.apache.org/jira/browse/HDDS-1424
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Elek, Marton
Assignee: Elek, Marton
The ./smoketest folder in the distribution package contains robotframework
based test scripts to test the main behaviour of Ozone.
The tests have two layers:
1. robot test definitions to execute commands and assert the results (on a
given host machine)
2. ./smoketest/test.sh which starts/stops the docker-compose based environments
AND execute the selected robot tests inside the right hosts
The second one (test.sh) has some serious limitations:
1. all the tests are executed inside the same container (om):
https://github.com/apache/hadoop/blob/5f951ea2e39ae4dfe554942baeec05849cd7d3c2/hadoop-ozone/dist/src/main/smoketest/test.sh#L89
Some of the tests (ozonesecure-mr, ozonefs) may require the flexibility to
execute different robot tests in different containers.
2. The definition of the global test set is complex and hard to understood.
The current code is:
{code}
TESTS=("basic")
execute_tests ozone "${TESTS[@]}"
TESTS=("auditparser")
execute_tests ozone "${TESTS[@]}"
TESTS=("ozonefs")
execute_tests ozonefs "${TESTS[@]}"
TESTS=("basic")
execute_tests ozone-hdfs "${TESTS[@]}"
TESTS=("s3")
execute_tests ozones3 "${TESTS[@]}"
TESTS=("security")
execute_tests ozonesecure .
{code}
For example for ozonesecure the TESTS is not used. And the usage of bash lists
require additional complexity in the execute_tests function.
I propose here a very lightweight refactor. Instead of including both the test
definitions AND the helper methods in test.sh I would separate them.
Let's put a test.sh to each of the compose directories. The separated test.sh
can include common methods from a main shell script. For example:
{code}
source "$COMPOSE_DIR/../testlib.sh"
start_docker_env
execute_robot_test scm basic/basic.robot
execute_robot_test scm s3
stop_docker_env
generate_report
{code}
This is a more clean and more flexible definition. It's easy to execute just
this test (as it's saved to the compose/ozones3 directory. And it's more
flexible.
Other example, where multiple containers are used to execute tests:
{code}
source "$COMPOSE_DIR/../testlib.sh"
start_docker_env
execute_robot_test scm ozonefs/ozonefs.robot
export OZONE_HOME=/opt/ozone
execute_robot_test hadoop32 ozonefs/hadoopo3fs.robot
execute_robot_test hadoop31 ozonefs/hadoopo3fs.robot
stop_docker_env
generate_report
{code}
With this separation the definition of the helper methods (eg.
execute_robot_test or stop_docker_env) would also be simplified.
