Method Detail

testToStringImplementation

public static void testToStringImplementation(@Nonnull
                              Object aObject)

Test the toString implementation of the passed object. It may not be empty, and consistent.

Parameters:

aObject - The object to be tested.

testDefaultImplementationWithEqualContentObject

public static <DATATYPE> void testDefaultImplementationWithEqualContentObject(@Nonnull
                                                              DATATYPE aObject1,
                                                              @Nonnull
                                                              DATATYPE aObject2)

Check if two different objects (who may not be the same) are equal to each other. Checks toString, equals and hashCode.

Type Parameters:

DATATYPE - The data type to be used

Parameters:

aObject1 - First object. May not be null.

aObject2 - Second object. May not be null.

testDefaultImplementationWithDifferentContentObject

public static <DATATYPE> void testDefaultImplementationWithDifferentContentObject(@Nonnull
                                                                  DATATYPE aObject1,
                                                                  @Nonnull
                                                                  DATATYPE aObject2)

Check if two different objects are different to each other. Checks toString, equals and hashCode.

Type Parameters:

DATATYPE - The data type to be used

Parameters:

aObject1 - First object. May not be null.

aObject2 - Second object. May not be null.

testDefaultSerialization

@Nonnull
public static <DATATYPE extends Serializable> DATATYPE testDefaultSerialization(@Nonnull
                                                                        DATATYPE aSerializable)

Test the serializability of objects. First writes the object to a byte array stream, and then tries to rebuild it from there. After reading it performs an equals check using testDefaultImplementationWithEqualContentObject(Object, Object)

Type Parameters:

DATATYPE - The type of object to be serialized.

Parameters:

aSerializable - The object to be written and read

Returns:

The newly read object

testGetClone

public static void testGetClone(@Nonnull
                ICloneable<?> aCloneable)

Test if the implementation ICloneable is OK. It creates a clone and than uses testDefaultImplementationWithEqualContentObject(Object, Object) to check for equality.

Parameters:

aCloneable - The cloneable object to test

testMicroTypeConversion

public static <T> T testMicroTypeConversion(@Nonnull
                            T aObj)

Test if the MicroTypeConverter is OK. It converts it to XML and back and than uses testDefaultImplementationWithEqualContentObject(Object, Object) to check for equality.

Type Parameters:

T - The data type to be used and returned

Parameters:

aObj - The object to test

Returns:

The object read after conversion

testInParallel

public static void testInParallel(@Nonnegative
                  int nCalls,
                  @Nonnull
                  Runnable aRunnable)

Run something in parallel

Parameters:

nCalls - The number of invocations of the passed runnable. Must be ≥ 0.

aRunnable - The runnable to execute. May not be null.

testInParallel

public static void testInParallel(@Nonnegative
                  int nCalls,
                  @Nonnull
                  IThrowingRunnable aRunnable)

Run something in parallel

Parameters:

nCalls - The number of invocations of the passed runnable. Must be ≥ 0.

aRunnable - The runnable to execute. May not be null.
