Hi @derekbit, it looks like test failed because I added error check to avoid lint issue. Can we assert err is nil here?

sparse-tools/sparse/test/client_test.go

Lines 255 to 256 in 813ac9e

	err := rest.TestServer(context.Background(), port, dst, timeout)
	assert.Nil(t, err)

It looks like server returns http: Server closed when server is closed. I update the test case.

Hi @derekbit, I tried to remove error check, but there still has data race condition. May you take a look when you have time? Thank you.

I am fine with merging this then using another ticket to track the data race
