# Passes if actual includes expected. This works for

# collections and Strings. You can also pass in multiple args
|
|
# and it will only pass if all args are found in collection.

|
|
# == Examples
|
|
#
|
|
# [1,2,3].should include(3)
|
|
# [1,2,3].should include(2,3) #would pass
|
|
# [1,2,3].should include(2,3,4) #would fail
|
|
# [1,2,3].should_not include(4)
