Class BaseComparatorTestCase<T>

java.lang.Object

io.github.astrapi69.AbstractTestCase<Integer,Boolean>

io.github.astrapi69.BaseComparatorTestCase<T>

Type Parameters:

T - the generic type of the objects to compare

public abstract class BaseComparatorTestCase<T>
extends AbstractTestCase<Integer,Boolean>

The abstract class BaseComparatorTestCase is for unit tests with Comparator. An example is in the unit test class DateComparatorTest in project silly-collections

Method Details

newActualList

protected abstract List<T> newActualList()

Abstract factory callback method that have to be overwritten for create the List with objects to sort in the sort scenario.

Returns:

the List with objects to test the sort algorithm

newComparator

protected abstract Comparator<T> newComparator()

Abstract factory callback method that have to be overwritten for create the specific comparator object

Returns:

the specific comparator

newExpectedSortedList

protected abstract List<T> newExpectedSortedList()

Abstract factory callback method that have to be overwritten for create the expected List with objects to test the sort algorithm in the sort scenario.

Returns:

the List with objects to test the sort algorithm

newExpectedUnsortedList

protected abstract List<T> newExpectedUnsortedList()

Abstract factory callback method that have to be overwritten for create the List with objects to sort in the sort scenario.

Note:This list have to be equal with newActualList()

Returns:

the List with objects to test the sort algorithm

newO1Equal

protected abstract T newO1Equal()

Abstract factory callback method that have to be overwritten for create the other object to compare in the scenario that the objects are equal.

Returns:

the new created object to compare

newO1GreaterThan

protected abstract T newO1GreaterThan()

Abstract factory callback method that have to be overwritten for create the first comparison object in the scenario greater than.

Returns:

the new created first comparison object

newO1LessThan

protected abstract T newO1LessThan()

Abstract factory callback method that have to be overwritten for create the first comparison object in the scenario less than.

Returns:

the new created first comparison object

newO2Equal

protected T newO2Equal()

Factory callback method that can be overwritten for create the other object to compare in the scenario that the objects are equal.

Returns:

the new created object to compare

newO2GreaterThan

protected abstract T newO2GreaterThan()

Abstract factory callback method that have to be overwritten for create the other object to compare in the scenario greater than.

Returns:

the new created object to compare

newO2LessThan

protected abstract T newO2LessThan()
