Matcher : be_in

[rx294]

Description

It will be very very useful to have a matcher that serves the following use case

describe nginx do
its('user') { should be_in AUTHORIZED_USER_LIST }
end

describe nginx do
its('module') { should_not be_in VULNURABLE_MODULE_LIST }
end

describe nginx do
its('user') { should_not be_in UNAUTHORIZED_USER_LIST }
end

Possible Solutions

The following code in matches.rb does the job

RSpec::Matchers.define :be_in do |list|
match do |item|
list.include?(item)
end

failure_message do |item|
"expected that #{item} to be in #{list}"
end
end

Thank you @arlimus, hope you guys can decide on the matcher's name soon...unless it can remain 'be_in' :)
