Testing Tools
it-tools is a copy of extensions-core/testing-tools (module
name druid-testing-tools.)
The testing tools are added to the Druid test Docker image. The
druid-testing-tools module defines most such additions. However,
integration-tests defines a custom node role which also must be
added to the image. integration-tests uses a different mechanism
to do that addition.
Here, we want a single extension for all the testing gizmos.
This is a direct copy of the druid-testing-tools
extension, along with a copy of the custom node role from
integration-tests.
The reason this is a copy, rather than fixing up druid-testing-tools
is that the existing integration-tests must continue to run and it
is very difficult to change or test them. (Which is the reason for
this parallel approach.) To keep backward compatibility, and to avoid
changing integration-tests, we keep the prior approach and make
copies here for the new approach.
The names should never clash: it-tools is only ever used
within the docker-test project, and the druid-testing-tools is
not included as a dependency.
Over time, once integration-tests are converted, then the
druid-testing-tools module can be deprecated in favor of this one.
