You are not allowed to write any production code unless it is to make a failing unit test pass
You are not allowed to write any more of a unit test than is sufficient to fail; and compilation failures are failures
You are not allowed to write any more production code than is sufficient to pass the one failing unit test
Stop coding when told

Any dead cell with exactly three live neighbours becomes a live cell as by reproduction
