AssertionMacro show all
Defined in:

Overview

Asserts the result contains the expected element

asserts("a string") { "world" }.includes('o')
asserts("an array") { [1,2,3] }.includes(2)
asserts("a range") { (1..15) }.includes(10)

You can also assert that the result does not contain an element:

denies("a string") { "world" }.includes('f')
denies("an array") { [1,2,3,4,5] }.includes(0)
denies("a range") { (1..15) }.includes(16)
