Description
As described in pydata/xarray#7238: a long list of failing tests might cause the github REST API to return
{"resource":"Issue","code":"custom","field":"body","message":"body is too long (maximum is 65536 characters)"}
A quick search tells me that we can either move that list somewhere else (which is not really useful, because then we could just look at the log), or we'd need to shorten / truncate the issue body.
In order not to blindly truncate, maybe we can summarize tests? For example, if we have variants of the same test that fail with the same message, we could summarize that as
xarray/tests/test_cftimeindex_resample.py::test_resample[<56 variants>]: TypeError: Grouper.__init__() got an unexpected keyword argument 'base'
Not sure what to do if the message changes, but this kind of "compression" would not lose too much information. Of course, if all of that still doesn't help we'd have to truncate (i.e. drop errors and add something like + another 285 failing tests / ... 285 failing tests omitted)
