        String lang = "en";

        List<AnalyzeToken> tokens = analyzer.analyze(text, field, lang);

        assertNotNull(tokens);
        assertEquals(8, tokens.size()); // "I'm" is split into "I" and "m" by our simple tokenizer
        assertEquals("Hello", tokens.get(0).getTerm());
        assertEquals("world", tokens.get(1).getTerm());
        assertEquals("How", tokens.get(2).getTerm());

3. Follow coding standards: `mvn formatter:format`
