Spectator::Block(T)

Inherits Spectator::Expression / Spectator::AbstractExpression / Reference / Object

Represents a block from a test. This is typically captured by an expect macro. It consists of a label and parameter-less block. The label should be a string recognizable by the user, or nil if one isn't available.

Constructors

new(block : -> T, label : Label = nil)

Creates the block expression from a proc. The proc will be called to evaluate the value of the expression. The label is usually the Crystal code for the proc. It can be nil if it isn't available.

Source

new(label : Label = nil, &block : -> T)
