druid/quidem-it

Quidem IT

Enables to write sql level tests easily. Can be used to write tests against existing test backends (ComponentSupplier) - by doing so the testcases can be moved closer to the excercised codes.

Usage

Install java&maven (if needed)

If you don't have java&maven - one way to set that up is by using sdkman like this:

# install sdkman
curl -s "https://get.sdkman.io" | bash
# at the end of installation either open a new terminal; or follow the instructions at the end

# install java&maven
sdk install java 11.0.23-zulu
sdk install maven

# run mvn to see if it works
mvn --version

# download druid sourcces (FIXME: change this to the main repo/branch before merging)
git clone --branch quidem-record https://github.com/kgyrtkirk/druid

Running these tests

• CI execution happens by a standard JUnit test QTest in this module
• the dev/quidem script can be used to run these tests (after the project is built)

Launching a test generating broker

• make sure to build the project first; one way to do that is:

  mvn install -pl quidem-it/ -am -DskipTests -Pskip-static-checks
  

• launch the broker instance with:

  mvn exec:exec -pl quidem-it -Dquidem.record.autostart=true
  

  • the broker will be running at http://localhost:12345
  • the used test configuration backend can configured by supplying quidem.uri

    mvn exec:exec -pl quidem-it -Dquidem.uri=druidtest:///?componentSupplier=ThetaSketchComponentSupplier
    

  • new record files can be started by calling http://localhost:12345/quidem/start
    • if quidem.record.autostart is omitted recording will not start
• after finished with the usage of the broker ; a new record-123.iq file will be in the project's worktree - it will contain all the executed statements
  • running dev/quidem -Dquidem.overwrite updates the resultsets of all iq files around there
  • rename the testfile to have a more descriptive name
