I guess generally you have identified that setting solr.data.dir isn't necessary?

yeah... I ran the test before and after the cahnge and everythign was green. Then I started looking for other tests that had solr.data.dir and did the same thing...

I at least checked where SolrInstance is used, data dir is the default so, indeed, at least where SolrInstance is used (like here), we don't need to relay it to "solr.data.dir".

Clearing properties in an @After or @AfterClass is always pointless since our test infra does that for us. Removing them everywhere would be a nice separate PR.

Dunno. The test still runs. Sometimes I think that some of this code just got copy/pasted over and over from test to test. Maybe it mattered for one test, and then it just kept living like a zombie. If you are really itnerested I can investigate (i.e ask Little Buddy what the deal is!).

I think it's a bit irresponsible to do this on the grounds that tests pass, without looking into the matter any further. Take a look at solr/core/src/test-files/solr/solr.xml. There are comments there about why the settings are different (e.g. distribUpdateSoTimeout) and various customizability that (unfortunately) our standard solr.xml doesn't have (but should).

I can see that the current situation could use improvement. Probably a separate PR should tackle that. Maybe that solr.xml should be in the solr-test-framework JAR as a resource that the test infra can reference and be used by 3rd parties. But also need a simple one-liner to install it into provided Path dir. Or alternatively a new property to the node props which contains a path to where solr.xml is.

I noticed that I documented the rule's startSolr as follows, meaning it has good test defaults. But only EmbeddedSolrServerTestRule follows this. I suppose then we have room to improve the Jetty side, after which it will indeed make sense to not copy a general test solr.xml.

I think I removed the vairuable and it still ran... I went and looked and yeah, they pretty much are the same:

Solrconfig files: Nearly identical except for a comment difference:

configset-1: Generic comment about being a "kitchen sink" config file for tests
configset-2: Specific comment stating "Small solrconfig with no /get handler defined, for use in TestConfigSets#testConfigSetOnReload"

Lets not change this in this PR.
"collection1" is the default, not "configset-1". It is an unfortunate kitchen-sink, with many tests using it. I'd rather see tests use one of several basic / standard configs without any quirks and then if needed modify it at runtime using config edit API or another approach on the fly.
