Example usage:

// myproject_test.go
import (
    "testing"
    
    "github.com/pwaller/go-deathtest"
)

func TestBadThing(t *testing.T) {
    if !deathtest.Run(t) { return }
    // something which causes go to crash
}

Then run go test as you normally would.

The test will pass only if TestBadThing() causes go to exit with a failure code. This is useful for testing that code fails when it should, without bringing down the whole test suite.

The death test runs in a separate go process, which causes deathtest.Run(t) to return true, allowing the crash branch to run.

Caveat: commandline options are not currently passed to the death tests.

Pull requests welcome.
