Constructor Detail

BinaryFunctionTest

protected BinaryFunctionTest(B testObject)

Creates a new test with the specified candidate.

Parameters:

testObject - the candidate of the test

Throws:

NullPointerException - if the specified test objects is null.

Method Detail

getInstance

public static final <S1,S2,T> BinaryFunctionTest<BinaryFunction<S1,S2,T>,S1,S2,T> getInstance(BinaryFunction<S1,S2,T> testObject)

Creates a new instance of this class with the specified testObject as test object.

Parameters:

testObject - the candidate of the test

Returns:

an instance of this class with the specified testObject as test object.

Throws:

NullPointerException - if the specified test objects is null.

assertConsistency

public void assertConsistency()

Checks consistency of all reading methods.

Overrides:

assertConsistency in class ObjectTest<B extends BinaryFunction<S1,S2,T>>

Throws:

AssertionFailedError - if the BinaryFunction contract is broken by the test object.

testWith

public void testWith(S1 arg1,
                     S2 arg2)

Performs various tests using the specified objects as arguments to the compute function of the tested binary function.

Parameters:

arg1 - a valid left argument to the underlying binary function

arg2 - a valid right argument to the underlying binary function

Throws:

AssertionFailedError - if the BinaryFunction contract is broken by the test object.

testWith

public void testWith(Object arg1)

Performs various tests using the specified object as identity element and sink.

Parameters:

arg1 - an arbitrary object

Throws:

AssertionFailedError - if the BinaryFunction contract is broken by the test object.

testWith

protected void testWith(S1 arg1,
                        S1 arg2,
                        S2 arg3)

Placeholder for associativity tests.

Parameters:

arg1 - a valid left argument to the underlying binary function

arg2 - a valid left and right argument to the underlying binary function

arg3 - a valid right argument to the underlying binary function

Throws:

AssertionFailedError - if the BinaryFunction contract is broken by the test object.
