Class: Riot::ExistsMacro Deprecated

Inherits:

Defined in:
lib/riot/assertion_macros/exists.rb

Overview

Deprecated.

Please use denies.nil instead of asserts.exists.

Asserts that the result of the test is a non-nil value. This is useful in the case where you don't want to translate the result of the test into a boolean value

asserts("test") { "foo" }.exists
should("test") { 123 }.exists
asserts("test") { "" }.exists
asserts("test") { nil }.exists # This would fail

You can also test for non-existince (being nil), but if you would better if you used the nil macro:

denies("test") { nil }.exists # would pass
asserts("test") { nil }.nil   # same thing

denies("test") { "foo" }.exists # would fail
