That's because you did not define arg1... Also, 'arg1="test"' does not work. arg1=test works. 'arg1=test' would work. "arg1=test" would work, 'arg1="test"' does not work.

$ cat t.bro
const arg1 ="x" &redef ;

event bro_init() {
    print arg1;
$ bro t.bro
$ bro t.bro arg1=test
$ bro t.bro 'arg1=test two'
test two
