assertAndReturnModelAttributeOfType

public static <T> T assertAndReturnModelAttributeOfType(ModelAndView mav,
                                                        String modelName,
                                                        Class<T> expectedType)

Checks whether the model value under the given modelName exists and checks it type, based on the expectedType. If the model entry exists and the type matches, the model value is returned.

Parameters:

mav - the ModelAndView to test against (never null)

modelName - name of the object to add to the model (never null)

expectedType - expected type of the model value

Returns:

the model value

assertCompareListModelAttribute

public static void assertCompareListModelAttribute(ModelAndView mav,
                                                   String modelName,
                                                   List expectedList)

Compare each individual entry in a list, without first sorting the lists.

Parameters:

mav - the ModelAndView to test against (never null)

modelName - name of the object to add to the model (never null)

expectedList - the expected list

assertModelAttributeAvailable

public static void assertModelAttributeAvailable(ModelAndView mav,
                                                 String modelName)

Assert whether or not a model attribute is available.

Parameters:

mav - the ModelAndView to test against (never null)

modelName - name of the object to add to the model (never null)

assertModelAttributeValue

public static void assertModelAttributeValue(ModelAndView mav,
                                             String modelName,
                                             Object expectedValue)

Compare a given expectedValue to the value from the model bound under the given modelName.

Parameters:

mav - the ModelAndView to test against (never null)

modelName - name of the object to add to the model (never null)

expectedValue - the model value

assertModelAttributeValues

public static void assertModelAttributeValues(ModelAndView mav,
                                              Map<String,Object> expectedModel)

Inspect the expectedModel to see if all elements in the model appear and are equal.

Parameters:

mav - the ModelAndView to test against (never null)

expectedModel - the expected model

assertSortAndCompareListModelAttribute

public static void assertSortAndCompareListModelAttribute(ModelAndView mav,
                                                          String modelName,
                                                          List expectedList,
                                                          Comparator comparator)

Compare each individual entry in a list after having sorted both lists (optionally using a comparator).

Parameters:

mav - the ModelAndView to test against (never null)

modelName - name of the object to add to the model (never null)

expectedList - the expected list

comparator - the comparator to use (may be null). If not specifying the comparator, both lists will be sorted not using any comparator.

assertViewName

public static void assertViewName(ModelAndView mav,
                                  String expectedName)

Check to see if the view name in the ModelAndView matches the given expectedName.

Parameters:

mav - the ModelAndView to test against (never null)

expectedName - the name of the model value
