Quiz:

When developing code using test driven development you should _____________________________________.

1. write your code and then test it to make sure it works
2. write your tests to cover as many eventualities as possible and then write your code to satisfy these conditions
3. write your code and tests in parallel so that you can adapt your tests to fit the situation as it evolves
4. adjust your tests to make sure that they all pass

Correct! The idea is that tests structure the writing of the code, not the other way around. If the tests correctly match your specification of the interactions between classes, you shouldn't need to adjust them at all.

Quiz:

In 1942, author Isaac Asimov introduced the "Three Laws of Robotics" to the world. These were:

1) A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2) A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
3) __________________________________________________.

1. On hearing the phrase Domo Arigato, Mr Roboto, all robots must respond with "Domo. Domo."
2. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law
3. A robot must know it is a robot
4. A robot can only pop some moves on their own time

Correct! The "Three Laws of Robotics" are a classic example of early thinking about the relationships between people and computers, and have, therefore, had a suprisingly large influence on computational ethics, at least informally. The correct response to "Domo Arigato, Mr Roboto" is, of course, "Dou itashimashite". "A robot must know it is a robot" is Kesarovski's Fifth Law of Robotics. Robots, strangely, can't do robotic dancing half as well as humans: see? Far too fluid. Rubbish.
