Constructor Detail

TestDataProvider

public TestDataProvider()

This class will invoke classes with random data

TestDataProvider

public TestDataProvider(Map<String,Function<String,Object>> customMap)

This class will invoke classes with random data from a custom map

Parameters:

customMap - The elements in this map will override the keys of the default map

Method Detail

getDefaultProviderMap

public static Map<String,Function<String,Object>> getDefaultProviderMap()

This method defines the default functions which generate random values for the corresponding classes

Returns:

A map with key (string), (value(Function<String, Object>))

fill

public <T> T fill(Class c,
                  String seed,
                  boolean tryComplexConstructorIfPossible)

This method will try to invoke the provided class.

Type Parameters:

T - Return type

Parameters:

c - The class which should be invoked

seed - The seed which should be used to generate the constructor parameters

tryComplexConstructorIfPossible - If true, try largest constructor first

Returns:

Initialized object

generateTestDataByNonStandardClass

protected <T> T generateTestDataByNonStandardClass(Class c,
                                                   String seed,
                                                   boolean complex)

public <T> T fillMutableWithNull(Class c)
                          throws IllegalAccessException,
                                 InvocationTargetException

This method will initialize the provided class with null pointer for the mutable variables and random values for the immutable variables (can't be null)

Type Parameters:

T - Return type

Parameters:

c - Class which should be initialized

Returns:

Initialized class

Throws:

IllegalAccessException - is thrown if the access to the class, field, method or constructor is not allowed.
