What type or syntax of regex is used when running go test -r <regex> commands? I'm using -list to find the tests I want to run before using -r, like this:
go test -list 'Foo' *.go
I'm having specific difficulty with the following two test names:
func TestSendTrap(...
func TestSendTrapFull(...
This works:
go test -list 'TestSendTrap\b' *.go
So I'm presuming PCRE syntax is being used, but command go doesn't detail.
It's Go regex, documented in regexp/syntax.
