abstract fun <T : Any> newCollectingPlant(subjectProvider: () -> T): CollectingAssertionPlant<T>Creates a CollectingAssertionPlant which is intended to be used as receiver object in lambdas to collect created Assertions inside the lambda.
Notice, that the plant might not provide a CollectingAssertionPlant.subject in which case it throws a PlantHasNoSubjectException if subject is accessed. Use newCheckingPlant instead if you want to know whether the assertions hold.
subjectProvider - The function which will either provide the subject for this plant or throw an
PlantHasNoSubjectException in case it cannot provide it. A CollectingAssertionPlant should evaluate the
subjectProvider only once.
Return
The newly created assertion plant.
