Бышева - Лабораторная работа #1

@ljaljushkin, @nikkrasn, @bobylkov-f please review
For test with repeated input conditions (or data), would be better to use `setUp` function with `@Before` annotation, and set there necessary environment, e.g. you could add 2 private filed `vector3D` and `vector2D`, init it into `setUp` and use in that test. So test would one-line and easy to understand.
