Feature: `unstub`
`unstub` removes a method stub, essentially cleaning up the method
stub early, rather than waiting for the cleanup that runs at the end
of the example. The newer non-monkey-patching syntax does not have a direct
equivalent but in most situations you can achieve the same behavior using
[`and_call_original`](../configuring-responses/calling-the-original-implementation). The difference is that `obj.unstub(:foo)` completely cleans up the `foo`
method stub, whereas `allow(obj).to receive(:foo).and_call_original` continues to
observe calls to the method (important when you are using [spies](../basics/spies)), which could affect the
method's behavior if it does anything with `caller` as it will include additional rspec stack
frames.
Background:
Given a file named "spec/spec_helper.rb" with:
"""ruby
RSpec.configure do |config|
config.mock_with :rspec do |mocks|
mocks.syntax = :should
end
end
"""
And a file named ".rspec" with:
"""
--require spec_helper

Scenario: Unstub a method
Given a file named "spec/unstub_spec.rb" with:
"""ruby
RSpec.describe "Unstubbing a method" do
it "restores the original behavior" do
string = "hello world"
string.stub(:reverse) { "hello dlrow" }
expect {
string.unstub(:reverse)
}.to change { string.reverse }.from("hello dlrow").to("dlrow olleh")
