### Question:
ValueUtil { public static int colorFor(AlarmSeverity severity) { return rgbSeverityColor.get(severity); } private  ValueUtil(); static Class<?> typeOf(Object obj); static Alarm alarmOf(Object obj); static Alarm alarmOf(Object value, boolean connected); static Alarm highestSeverityOf(final List<Object> args, final boolean considerNull); static Time latestTimeOf(final List<Object> args); static Time latestValidTimeOrNowOf(final List<Object> args); static Time timeOf(Object obj); static Display displayOf(Object obj); static boolean displayHasValidDisplayLimits(Display display); static Double normalizedNumericValueOf(Object obj); static Double normalize(Number value, Display display); static Double normalize(Number value, Number lowValue, Number highValue); static Double numericValueOf(Object obj); static BufferedImage toImage(VImage vImage); static VImage toVImage(BufferedImage image); static boolean displayEquals(Display d1, Display d2); static void setAlarmSeverityColorMap(Map<AlarmSeverity, Integer> map); static int colorFor(AlarmSeverity severity); static DateTimeFormatter getDefaultTimestampFormat(); static void setDefaultTimestampFormat(DateTimeFormatter defaultTimestampFormat); static NumberFormat getDefaultNumberFormat(); static void setDefaultNumberFormat(NumberFormat defaultNumberFormat); static ValueFormat getDefaultValueFormat(); static void setDefaultValueFormat(ValueFormat defaultValueFormat); static ListNumber numericColumnOf(VTable table, String columnName); static List<String> stringColumnOf(VTable table, String columnName); static List<ArrayDimensionDisplay> defaultArrayDisplay(VNumberArray array); static List<ArrayDimensionDisplay> defaultArrayDisplay(ListInt sizes); static VNumberArray subArray(VNumberArray array, int index);  }### Answer:
@Test public void colorFor1() { assertThat(colorFor(AlarmSeverity.NONE), equalTo(Color.GREEN.getRGB())); assertThat(colorFor(AlarmSeverity.MINOR), equalTo(Color.YELLOW.getRGB())); assertThat(colorFor(AlarmSeverity.MAJOR), equalTo(Color.RED.getRGB())); assertThat(colorFor(AlarmSeverity.INVALID), equalTo(Color.MAGENTA.getRGB())); assertThat(colorFor(AlarmSeverity.UNDEFINED), equalTo(Color.DARK_GRAY.getRGB())); }
