Package de.cuioss.test.valueobjects

Class MapperTest<M extends Function<S,T>,S,T>

java.lang.Object

de.cuioss.test.valueobjects.MapperTest<M,S,T>

Type Parameters:

M - Mapper: The type of the Mapper

S - Source: The type of the source-Objects to be mapped from

T - Target: The type of the source-Objects to be mapped to

All Implemented Interfaces:

TestObjectProvider<M>, GeneratorRegistry

public class MapperTest<M extends Function<S,T>,S,T>
extends Object
implements GeneratorRegistry, TestObjectProvider<M>

Allows to test a mapper implementing a Function to map a (pseudo-)DTO object based on whatever technology (FHIR, ...) to a DTO object. The actual test-method is verifyMapper(). The mapper-test-configuration is defined with VerifyMapperConfiguration For simple uses-case, like well designed beans there is no special configuration needed

• In case the mapper needs to be configured in a special way (not using the default constructor) you can overwrite getUnderTest()
• The metadata / creation of the source objects can be adjusted in multiple ways:
  • PropertyMetadata: The annotations on class level affect the metadata for the source-objects
  • resolveSourcePropertyMetadata(): can be overwritten as an alternative for using PropertyMetadata annotations
  • getSourceInstantiator(RuntimeProperties): If not overwritten the default implementation chooses the BeanInstantiator in order to generate source-objects.
• The metadata target objects is derived by reflection. Caution: For more complex objects that can not be created by the generator framework you must provide either a TypedGenerator, see GeneratorRegistry or overwrite anyTargetObject()

Constructor Details

MapperTest

public MapperTest()

Method Details

intializeTypeInformation

protected void intializeTypeInformation()

Reads the type information and fills the fields #getMapperClass(), #getSourceClass(), #getTargetClass(). It runs it checks only once

verifyMapper

@Test
public void verifyMapper()

Shorthand for calling verifyMapper(PropertyReflectionConfig) with null

verifyMapper

public void verifyMapper(PropertyReflectionConfig targetConfig)

The actual test-method to be run

Parameters:

targetConfig - providing configuration, may be null

getUnderTest

public M getUnderTest()

Specified by:

getUnderTest in interface TestObjectProvider<M extends Function<S,T>>

Returns:

the bean to be tested. Usually instantiated by Inject or other concrete

resolveSourcePropertyMetadata

public List<PropertyMetadata> resolveSourcePropertyMetadata()

Resolves the PropertyMetadata for the source objects by using reflection and the annotations PropertyConfig and / PropertyConfigs if provided.

Returns:

a List of PropertyMetadata defining the base line for the configured attributes

resolveTargetPropertyMetadata

public List<PropertyMetadata> resolveTargetPropertyMetadata(PropertyReflectionConfig config)

Resolves the PropertyMetadata for the target objects by using reflection

Parameters:

config - providing configuration, may be null

Returns:

a List of PropertyMetadata defining the base line for the configured attributes

anyTargetObject

public T anyTargetObject()

Returns:

a target object to be used for reflection based resolving of PropertyMetadata. The default implementation uses the GeneratorRegistry in order to instantiate a corresponding object. For more complex objects you should add a corresponding TypedGenerator, see GeneratorRegistry

getSourceInstantiator

public ParameterizedInstantiator<? extends S> getSourceInstantiator(RuntimeProperties runtimeProperties)

Parameters:

runtimeProperties - to be used for creating the ParameterizedInstantiator

Returns:

the ParameterizedInstantiator to be used for instantiating source-object. If not overwritten it default to the beanInstantiator
