Review comment:
To actually evaluate the value providers, the pipeline needs to be executed
right? Cause these are realistically only 'known' at runtime. The tests in
`TestReadFromBigQuery` just validate the input data to the initialisation.
We can of course just validate that query is of type `ValueProvider` after
initialising a pipeline, but I figured we want to check that the value provider
query is actually evaluated to a string type on pipeline execution.
Am I perhaps missing something?
