Remove those silly arguments checks. If you do keep them in for some reason, change the return type. We now have mixed return types :/

• upgrading to JUnit 5
• displaying the input in assertion messages
• removal of Integer constructor, which triggers deprecation warnings (fixing this issue)

src/test/java/TipCalculatorTest.java:8: warning: [removal] Integer(int) in Integer has been deprecated and marked for removal
assertEquals(new Integer(2), TipCalculator.calculateTip(30d, "poor"));
