ddf-test

Test suite for DDF

Running test suite

Change the engine in [global] section and queries for your engine in [your engine] section in ddf-conf/ddf_spec.ini. Add a ddf.ini file for your engine.

You can also create your own BaseSpec and then add its name to the baseSpec field in [your engine] section. An example baseSpec for AWS engine known as BaseSpecAWS is given. To use this baseSpecAWS add the AWS assembly jars and uncomment the lines corresponding to the same in baseSpecAWS.

There are two ways to add the ddf-on-x jars:

  • Execute the shell script which takes the location of a directory which has the ddf-on-x jars.
  • Add ddf-on-x implementation jar to lib directory.

Running the tests using the shell script

$ ./bin/DDFTestRunner.sh

//Enter the required jar files and java Options in the command prompt.

Hello, welcome to ddf-test. This script will ask you choose an engine and run the tests.

Choose your java options for tests (for spark: -Dhive.metastore.warehouse.dir=/tmp/hive/warehouse )

Enter your java options or leave blank and press [ENTER]:

Enter your ddf-on-x jar's location(required) and press [ENTER]:

Running the tests in sbt console

In this case , the lib directory contains ddf-on-x jars and any changes of java Options are made in build.sbt.

$ sbt

//to run all the tests
sbt> test

Reports:

To open the Html Reports of the tests generated, open index.html from target/test-reports directory in a web browser. Clicking on the DDFSpec suite, will show the test reports.

Note:

  • For spark implementation, before running tests, you may need to execute the following to remove files:
$ rm -r "./metastore_db/"
$ rm -r "/tmp/hive/"  //Run this if you used the java options for hive metastore directory for spark
  • Make sure that there are no duplicate jars present when adding jars to lib directory or when giving the jar directory in the shell script. Do not include scalatest and junit jars . Do not remove the asm-all-4.0.jar from the lib directory as it contains some essential classes required for the scalatest to generate a html report.
