private String EXPECTED_MESSAGE = "The key to efficient learning is practice!";
For me this var make coupling between tests, what do you think about it?

Also, just wondering, regarding this test class, why do you need to crazy logic in the com.bobocode.intro.ExerciseIntroductionTest#encodeMessageReturnsCorrectPhrase? Vs just
assertEquals(exerciseIntroduction.encodeMessage(EXPECTED_MESSAGE), "VGhlIGtleSB0byBlZmZpY2llbnQgbGVhcm5pbmcgaXMgcHJhY3RpY2Uh");
