should arrangement what's duty section exam runs?

as i am coding section tests, i tend i insert following lines:

console.writeline("starting interopapplication, runinbackground set true...");
try
{
    interopapplication concentration = new interopapplication(true);
    application.start();
    console.writeline("application started correctly");
}
catch(exception e)
{
    assert.fail(string.format("interopapplication unsuccessful start: {0}", e.tostring()));
}

//test formula continues ...

all tests graceful many same thing. displaying information since failed, displaying information doing. i haven't any formal methods section tests should coded. should displaying information doing? should tests speechless arrangement any information during doing, wholly arrangement disaster messages?
