Description

I'm attempting to debug my fuzz test via:

dlv test . -- -test.parallel=1 -test.fuzzminimizetime=0 -test.fuzz FuzzDSO -test.fuzztime=30s

After dlv starts and I continue, the process exits with error:

(dlv) c
testing: -test.fuzzcachedir must be set if -test.fuzz is set
...

Where -test.fuzzcachedir is an internal option flag:

  -test.fuzzcachedir string
    	directory where interesting fuzzing inputs are stored (for use only by cmd/go)

In order to work around this error I need to manually provide -test.fuzzcachedir:

dlv test . -- -test.parallel=1 -test.fuzzminimizetime=0 -test.fuzz FuzzDSO -test.fuzztime=30s -test.fuzzcachedir=./testdata

Instead, I expect dlv test to figure it out without similarly to how go test does.
