StateArrayReverse test case
|
|
|
|
The purpose of this test case is verify what happens when re-ordering the Widgets / Components
|
|
of same type. Here, the test is done with built-in text (not with a own subclass of JSView)
|
|
|
|
The expectation is that TextElement objects are created only once, then put to new order.
|
|
For this to work, each time a TextComponent is created it needs to be assigned the same unique key.
|
|
|
|
This is why anArray is not a simple array of strings. strings are not uniquely identifyable.
|
|
Therefore, the app needs to provide a unique id for each array item.
|
|
We do so by making each array item an object with a unique id.
|
|
|
|
this id should be used as the 'key' argument when creating a Text.
