abstract infix fun and(assertions: Builder<T>.() -> Unit): Builder<T>
Evaluates a block of assertions on the current subject.
The main use for this method is after strikt.assertions.isNotNull or strikt.assertions.isA in order that a group of assertions can more conveniently be performed on the narrowed subject type.
This method may be used as an infix function which tends to enhance readability when it directly follows a lambda.
