Usage

A good example can be found here. This is a simple test that always expects a SecurityException:

class Test {
    static class DenyAll extends GroovyValueFilter {
        Object filter(Object o) { throw new SecurityException('Denied!') }
    }
    @Test(expected = SecurityException)
    void testScript() {
        final sh = new GroovyShell(new CompilerConfiguration()
                .addCompilationCustomizers(new SandboxTransformer()))
        new DenyAll().register()
        sh.evaluate('println hi')
    }
}
