Description
The test schema files are intimidating. There are about a zillion of them, and making a change in any of them risks breaking some other test. That leaves people three choices:
1> add what they need to some existing schema. Which makes schemas bigger and bigger and bigger.
2> create a new schema file, adding to the proliferation thereof.
3> Look through all the existing tests to see if they have something that works.
The recent work on LUCENE-7705 is a case in point. We're adding a maxLen parameter to some tokenizers. Putting those parameters into any of the existing schemas, especially to test < 255 char tokens is virtually guaranteed to break other tests, so the only safe thing to do is make another schema file. Adding to the multiplication of files.
As part of SOLR-5260 I tried creating the schema on the fly rather than creating a new static schema file and it's not hard. WDYT about making this into some better thought-out utility?
At present, this is pretty fuzzy, I wanted to get some reactions before putting much effort into it. I expect that the utility methods would eventually get a bunch of canned types. It's reasonably straightforward for primitive types, if lengthy. But when you get into solr.TextField-based types it gets less straight-forward.
We could manage to just move the "intimidation" from the plethora of schema files to a zillion fieldTypes in the utility to choose from...
Also, forcing every test to define the fields up-front is arguably less convenient than just having some canned schemas we can use. And erroneous schemas to test failure modes are probably not very good fits for any such framework.
steve_rowe and hossman_lucene@fucit.org in particular might have something to say.
