end_with matcher

Use the end_with matcher to specify that a string or array ends with the
expected characters or elements.

  "this string".should end_with "string"
  "this string".should_not end_with "stringy"
  [0, 1, 2].should end_with 1, 2
Scenarios
string usage
Given
a file named "example_spec.rb" with:
describe "this string" do
  it { should end_with "string" }
  it { should_not end_with "stringy" }

  # deliberate failures
  it { should_not end_with "string" }
  it { should end_with "stringy" }
end
When
I run rspec example_spec.rb
Then
the output should contain all of these:
4 examples, 2 failures
expected "this string" not to end with "string"
expected "this string" to end with "stringy"
array usage
Given
a file named "example_spec.rb" with:
describe [0, 1, 2, 3, 4] do
  it { should end_with 4 }
  it { should end_with 3, 4 }
  it { should_not end_with 3 }
  it { should_not end_with 0, 1, 2, 3, 4, 5 }

  # deliberate failures
  it { should_not end_with 4 }
  it { should end_with 3 }
end
When
I run rspec example_spec.rb
Then
the output should contain all of these:
6 examples, 2 failures
expected [0, 1, 2, 3, 4] not to end with 4
expected [0, 1, 2, 3, 4] to end with 3
