Method Details

ofSize

default IteratorArbitrary<T> ofSize(int size)

Fix the size to size.

Specified by:

ofSize in interface SizableArbitrary<T>

Specified by:

ofSize in interface StreamableArbitrary<T,Iterator<T>>

Parameters:

size - The size of the generated iterator

Returns:

new arbitrary instance

ofMinSize

IteratorArbitrary<T> ofMinSize(int minSize)

Set lower size boundary minSize (included).

Specified by:

ofMinSize in interface SizableArbitrary<T>

Specified by:

ofMinSize in interface StreamableArbitrary<T,Iterator<T>>

Parameters:

minSize - The minimum size of the generated iterator

Returns:

new arbitrary instance

ofMaxSize

IteratorArbitrary<T> ofMaxSize(int maxSize)

Set upper size boundary maxSize (included).

Specified by:

ofMaxSize in interface SizableArbitrary<T>

Specified by:

ofMaxSize in interface StreamableArbitrary<T,Iterator<T>>

Parameters:

maxSize - The maximum size of the generated iterator

Returns:

new arbitrary instance

withSizeDistribution

@API(status=EXPERIMENTAL,
     since="1.5.3")
IteratorArbitrary<T> withSizeDistribution(RandomDistribution uniform)

Set random distribution distribution of size of generated iterator. The distribution's center is the minimum size of the generated iterator.

Specified by:

withSizeDistribution in interface SizableArbitrary<T>

Specified by:

withSizeDistribution in interface StreamableArbitrary<T,Iterator<T>>

uniqueElements

@API(status=MAINTAINED,
     since="1.4.0")
IteratorArbitrary<T> uniqueElements()

Add the constraint that elements of the generated iterator must be unique, i.e. no two elements must return true when being compared using Object.equals(Object).

The constraint can be combined with other uniqueElements(Function) constraints.

Specified by:

uniqueElements in interface StreamableArbitrary<T,Iterator<T>>

Returns:

new arbitrary instance

uniqueElements

@API(status=MAINTAINED,
     since="1.4.0")
IteratorArbitrary<T> uniqueElements(Function<T,Object> by)

Add the constraint that elements of the generated iterator must be unique relating to an element's "feature" being extracted using the by function. The extracted features are being compared using Object.equals(Object).

The constraint can be combined with other uniqueElements(Function) constraints.

Specified by:

uniqueElements in interface StreamableArbitrary<T,Iterator<T>>

Returns:

new arbitrary instance
