This package runs tests and sub-tests both in parallel. The purpose of
this is to illustrate a bug in the output of go test -json (and also
go tool test2json) using Go 1.14 and Go 1.14.1. See lines 86-87 of
"output-go1.14.1.txt" for evidence of this.
At SmartyStreets we have built our own testing library
which makes heavy use of parallel tests and sub-tests (see t.Parallel()).
After upgrading to Go 1.14 we noticed that failure output wasn't being presented
correctly by the GoLand test runner.
