Little surprises #7: more Qt versus the preprocessor misery

Trying to be a good kid. Writing tests as I code. Testing the edge cases. "Hey, this should throw, does Qt have a test for that?" Yeah, its QVERIFY_EXCEPTION_THROWN. Great, let's use that!

void suspisiousFunctionCallThrows()
{
    // Define badInput and otherParam;
    
    QVERIFY_EXCEPTION_THROWN(suspicisouFunction(badInput,otherParam), std::runtime_error);
}

It doesn't compile. Why not? Commas again, of course.

And it is conceptually easy to fix: you just create some blind wrapper than make the offending call without taking multiple argument.

void suspiciousFunctionCallThrows()
{
    // Define badInput and otherParam;
    
    std::function f = [&]{
    	suspiciousFunction(badInput,otherParam);
    }

    QVERIFY_EXCEPTION_THROWN(f(), std::runtime_error);
}

Not exactly a featured stop on the "Look at our transparent tests" tour, is it?
