testing: testing a list of packages blocks the real-time output #27826
Someone must examine and confirm this is a valid issue and not a duplicate of an existing one.
An issue that has been verified to require only test changes, not just a test failure.
What version of Go are you using (
go version go1.11 darwin/amd64
Does this issue reproduce with the latest release?
Yes, reproduced on tip -
go version devel +ce58a39fca Thu Sep 20 22:52:44 2018 +0000 darwin/amd64
What operating system and processor architecture are you using (
What did you do?
go test -v -count=1 ./...doesn't print real-time test output if you got subpackages.
What did you expect to see?
I expect to see the output successively as the test is running.
And I will see it if run
go test -v -count=1 .instead.
What did you see instead?
./...doesn't produce real-time output.
The output is produced only when all the tests are finished.
It's not convenient when you run tests on a CI and see only "go test -v ./..." line for several minutes.
You don't have any idea if the tests have stuck somewhere or they are just too slow.
I understand that such behaviour may be connected with running the tests in parallel, but maybe we could do anything about it?
