// These initial tests are for bootstrapping.  They verify that we can
// basically use the testing infrastructure itself to check if the test
// system is working.
//
// These tests use will break down the test runner badly in case of
// errors because if they simply fail, we can't be sure the developer
// will ever see anything (because failing means the failing system
// somehow isn't working! :-)
//
// Do not assume *any* internal functionality works as expected besides
// what's actually tested here.
