Samples

• Validation test for roman translation

assertTrue(
    assertThrows(ConversionException.class, () -> ConvertToArabic.fromRoman("VX"), "")
        .getMessage()
        .contains("Sintaxis violation"));

• Convert from roman to arabic

assertEquals(1914, ConvertToArabic.fromRoman("MCMXIV"));

• Convert from arabic to roman

assertEquals("MCMXIV", ConvertToRoman.fromArabic(1914));

• Create your own alphabet and convert to arabic

Alphabet alphabet =
    Alphabet.builder()
        .One("F")
        .Five("A")
        .Ten("C")
        .Fifty("U")
        .OneHundred("N")
        .FiveHundred("D")
        .Thousand("O")
        .build();

assertEquals(1914, ConvertToArabic.fromAlphabet("ONOCFA", alphabet));

• If your alphabet is incomplete then you will receive an IncompleteAlphabetException

Alphabet.Builder alphabet =
    Alphabet.builder().One("G").Five("O").Ten("N").Fifty("Z").OneHundred("A");

assertTrue(
    assertThrows(
        IncompleteAlphabetException.class, () -> alphabet.build(), "")
            .getMessage()
            .contains("Alphabet must have 7 defined pair key-values")
    );

• Remember: the alphabet created is immutable

assertNotNull(
    assertThrows(
        UnsupportedOperationException.class, () -> alphabet.getAlphabet().put("G", 19), ""));
