Test2::Compare::Array - Internal representation of an array comparison.


This module is an internal representation of an array for comparison purposes.


$ref = $arr->inref()

If the instance was constructed from an actual array, this will return the reference to that array.

$bool = $arr->ending

Set this to true if you would like to fail when the array being validated has more items than the check. That is, if you check indexes 0-3 but the array has values for indexes 0-4, it will fail and list that last item in the array as unexpected. If set to false then it is assumed you do not care about extra items.

$hashref = $arr->items()

Returns the hashref of key => val pairs to be checked in the array.


Accepts a hashref to permit indexes to be skipped if desired.

Note: that there is no validation when using set_items, it is better to use the add_item interface.

$arrayref = $arr->order()

Returns an arrayref of all indexes that will be checked, in order.


Sets the order in which indexes will be checked.

Note: that there is no validation when using set_order, it is better to use the add_item interface.

$name = $arr->name()

Always returns the string "<ARRAY>".

$bool = $arr->verify(got => $got, exists => $bool)

Check if $got is an array reference or not.

$idx = $arr->top_index()

Returns the topmost index which is checked. This will return undef if there are no items, or 0 if there is only 1 item.


Push an item onto the list of values to be checked.

$arr->add_item($idx => $item)

Add an item to the list of values to be checked at the specified index.

$arr->add_filter(sub { ... })

Add a filter sub. The filter receives all remaining values of the array being checked, and should return the values that should still be checked. The filter will be run between the last item added and the next item added.

@deltas = $arr->deltas(got => $got, convert => \&convert, seen => \%seen)

Find the differences between the expected array values and those in the $got arrayref.
