On assertions

Answer the following questions:

1. The following assertion fails assertTrue(3 * .4 == 1.2). Explain why and describe how this type of check should be done.

2. What is the difference between assertEquals and assertSame? Show scenarios where they produce the same result and scenarios where they do not produce the same result.

3. In classes we saw that fail is useful to mark code that should not be executed because an exception was expected before. Find other uses for fail. Explain the use case and add an example.

4. In JUnit 4, an exception was expected using the @Test annotation, while in JUnit 5 there is a special assertion method assertThrows. In your opinion, what are the advantages of this new way of checking expected exceptions?
