### Question:
HelmPathUtils { public String filename(final TokenMatcher.State state) { return match(state, "filename"); }  String filename(final TokenMatcher.State state); String contentFilePath(final TokenMatcher.State state); String extension(final TokenMatcher.State state); TokenMatcher.State matcherState(final Context context); String buildAssetPath(final TokenMatcher.State matcherState); String buildContentAssetPath(final TokenMatcher.State matcherState);  }### Answer:
@Test public void filename() throws Exception { Map<String, String> map = new HashMap<>(); map.put("filename", FILENAME); when(state.getTokens()).thenReturn(map); String result = underTest.filename(state); assertThat(result, is(equalTo(FILENAME))); }
