collectNullable

Use this function if you want to make Assertion about a feature or you perform a type transformation or any other action which results in a sub-AssertionPlantNullable being created and you do not require this resulting plant.

Or in other words, you do not want to make further assertions about the resulting subject in the resulting sub assertion plant.

This function can be useful in several cases. For instance:

• You are writing an assertion about a feature often enough so that it deserves an own assertion function (see e.g. MapAssertions.hasSize)
• You want the collected assertion to be part of an AssertionGroup

Parameters

plant - The plant from which the AssertionPlantNullable.subject will be used as subject of the CollectingAssertionPlantNullable.

assertionCreator - A lambda which typically creates a sub AssertionPlantNullable and adds assertions to it. For instance, if you create a feature assertion or a type transformation assertion, you will typically end up creating a sub assertion plant which delegates created Assertions to the CollectingAssertionPlantNullable.

Exceptions

IllegalArgumentException - in case the given assertionCreator did not create a single assertion, did not pass it to the CollectingAssertionPlantNullable respectively.

Return
The collected assertions as an AssertionGroup with an InvisibleAssertionGroupType.
