Project: RSpec Expectations 3.5

`end_with` matcher

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

  expect("this string").to end_with "string"
  expect("this string").not_to end_with "stringy"
  expect([0, 1, 2]).to end_with 1, 2
Scenarios
string usage
Given
a file named "example_spec.rb" with:
RSpec.describe "this string" do
  it { is_expected.to end_with "string" }
  it { is_expected.not_to end_with "stringy" }

  # deliberate failures
  it { is_expected.not_to end_with "string" }
  it { is_expected.to 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:
RSpec.describe [0, 1, 2, 3, 4] do
  it { is_expected.to end_with 4 }
  it { is_expected.to end_with 3, 4 }
  it { is_expected.not_to end_with 3 }
  it { is_expected.not_to end_with 0, 1, 2, 3, 4, 5 }

  # deliberate failures
  it { is_expected.not_to end_with 4 }
  it { is_expected.to 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
