### Question:
BBCodeListPreprocessor implements TextProcessor { @Override public String process(String bbEncodedText) { return process(new StringBuilder(bbEncodedText)).toString(); }  @Override String process(String bbEncodedText); @Override CharSequence process(CharSequence bbEncodedText); @Override StringBuilder process(StringBuilder bbEncodedText); @Override StringBuffer process(StringBuffer bbEncodedText);  }### Answer:
@Test(dataProvider="validLists") public void testProcess(String bbCode, String expectedResult) { String result = service.process(bbCode); assertEquals(result, expectedResult); }
@Test(dataProvider="validLists") public void testProcessStringBuilder(String bbCode, String expectedResult) { StringBuilder result = service.process(new StringBuilder(bbCode)); assertEquals(result.toString(), expectedResult); }
@Test(dataProvider="validLists") public void testProcessStringBuffer(String bbCode, String expectedResult) { StringBuffer result = service.process(new StringBuffer(bbCode)); assertEquals(result.toString(), expectedResult); }
@Test(dataProvider="validLists") public void testProcessCharSequence(String bbCode, String expectedResult) { CharSequence result = service.process(new StringBuilder(bbCode).subSequence(0, bbCode.length())); assertEquals(result.toString(), expectedResult); }
@Test(dataProvider = "nestedLists") public void testProcessNestedLists(String bbCode, String expectedResult) { CharSequence result = service.process(new StringBuilder(bbCode)); assertEquals(result.toString(), expectedResult); }
@Test(dataProvider = "badLists") public void testBadLists(String bbCode, String expected) { CharSequence result = service.process(new StringBuilder(bbCode)); assertEquals(result.toString(), expected); }
