[go-nuts] go test -run regexp

Hello all,

I want to run all tests except specific one. This test is "Test_main".

the command go test -h displays :
...
-run regexp
             Run only those tests and examples matching the regular
             expression.
...

So I try :
go test -run=^\(\(?\!Test_main\).\)*$ ./...

But unfortunately, that doesn't work :
testing: invalid regexp for -test.run: error parsing regexp: invalid or
unsupported Perl syntax: `(?!`


Is it possible to do this ?

Many thx
Best
Jérôme
