Subject [jira] [Created] (HDDS-1424) Support multi-container robot test execution
Date Thu, 11 Apr 2019 13:51:00 GMT
Elek, Marton created HDDS-1424:

             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):


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:
   execute_tests ozone "${TESTS[@]}"
   execute_tests ozone "${TESTS[@]}"
   execute_tests ozonefs "${TESTS[@]}"
   execute_tests ozone-hdfs "${TESTS[@]}"
   execute_tests ozones3 "${TESTS[@]}"
   execute_tests ozonesecure .

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:


source "$COMPOSE_DIR/../testlib.sh"


execute_robot_test scm basic/basic.robot

execute_robot_test scm s3




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:


source "$COMPOSE_DIR/../testlib.sh"


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



With this separation the definition of the helper methods (eg. execute_robot_test or stop_docker_env)
would also be simplified.
