Problem: 

ERROR causing test failure: Test data folder missing

Solution:

ssh hudson
cd ~/hudson/jobs/integration-tests/workspace/integration-tests/targets/
ln -s ../../../../../test-data test-data


Note: If this happening on stage-jenkins you have to do the following:

ssh stage-jenkins
cd ~/hudson/tests-16.05/integration-tests/targets/
ln -s ../../../test-data test-data
