Class: Riot::SizeMacro

Inherits:
AssertionMacro show all
Defined in:
lib/riot/assertion_macros/size.rb

Overview

Asserts that result’s size is as expected. Expected size can be specified as a number or a range.

asserts("a string") { 'washington' }.size(9..12)
asserts("an array") { [1, 2, 3] }.size(3)
asserts("a hash") { {:name => 'washington'} }.size(1)

To ensure that the result is not of a specific size:

denies("a string") { 'washington' }.size(4)
denies("an array") { [1, 2, 3] }.size(6..10)
denies("a hash") { {:name => 'washington'} }.size(2)
