SOLR-9285 is/has added a new TestRandomFlRTGCloud for testing out random permutations of fl params in RTG requests.
simple field names, field renames, field globs, and ValueSources/functions are already tested – adding additional DocTransformers is fairly straight forward by implementing a simple FlValidator.
This issue is being filed to track the work needed to:
- review the list of all DocTransformers in solr and add test coverage of them in this method
- file any blocker issues if new bugs are found in this process
- once all DocTransformers are accounted for, update TestRandomFlRTGCloud to programatically compare the list of FlValidator's it knows about with the list of all DocTransformers (similar to how QueryEqualityTest.testParserCoverage works) to fail the test if anyone adds a DocTransformer w/o adding corisponding test coverage to this class.
