I would like to execute my tests with a specific launcher. I am using <testing.launcher> for that. The problem is that valgrind for example expects the arguments that are specific for it to be specified before the executable and this is why <testing.arg> can not be used for that.

Any suggestions?

... or if there is no more elegant way to do that, how I can specify an variable with space in it.
I tried to escape the space with \, to put it in quotes - nothing seems to work.

Something like:
local launcher_command = "valgrind --memcheck:foo=bar" ;

Thanks in advance
