commit 6ae5c95b246ce61ec4382f260ad99ae739967786

macOS, 12.3.1, Intel,
Running on local docker,

Description:

When I run the go example it ends with failed outcome:

testground run single --plan=example --testcase=output --builder=docker:go --runner=local:docker --instances=1

This is somewhat expected: these examples do not use the InitializedTestCase wrapper.
Without this wrapper, the test won't send the "success message" to testground and it'll assume the test failed.

See also: #1303 (comment)

One fix is to add the wrapper to the tests:

• tests: https://github.com/testground/testground/blob/master/plans/example/main.go
• example: https://github.com/testground/testground/blob/master/plans/network/main.go#L9

A more thoughtful fix might be to make InitializedTestCase the new default, see:
