Hi @MikeThomsen sorry for the delay, I have been just very busy. It turns
out there have been some changes in the flow XML format, which I have fixed
against the latest GA version: now all of the tests are executed properly.
I have also introduced strict version checking: the NiFi version referenced
in the flow file is checked against the actual version of the NiFi distribution
used so that we can avoid confusion in the future.
If a user tries to run the test harness with a flow created using a
different version of NiFi than the one actually used, this will fail fast,
preventing a non functioning installation leaving the user being confused why
it does not work properly.

> Key: NIFI-5318
> URL: https://issues.apache.org/jira/browse/NIFI-5318
> Project: Apache NiFi
> Issue Type: New Feature
> Reporter: Peter Horvath
> Priority: Major
>
> Currently, it is not really possible to automatically test the behaviour of a
> specific NiFi flow and make unit test type asserts if it works as expected.
> For example, if the expected behaviour of a NiFi flow is that a file placed
> to a specific directory will trigger some operation after which some output
> file will appear at another directory, once currently can only do one thing:
> test the NiFi flow manually.
> Manual testing is especially hard to manage if a NiFi flow is being actively
> developed: any change to a complex, existing NiFi flow might require a lot of
> manual testing just to ensure there are no regressions introduced.
> Some kind of Java API that allows managing a NiFi instance and manipulating
> flow deployments like for example, [Codehaus
> Cargo|]https://codehaus-cargo.github.io/] would be of great help.
