It allows you to use `block_is_expected` similarly to how you would use `is_expected` if a block was wrapping the subject. Supports the same versions of Ruby that RSpec does, 1.8.7 - current ruby-head, as well as the JRuby equivalents. +<div id="badges"> +[![CI Build][🚎dl-cwfi]][🚎dl-cwf] +[![Test Coverage][🔑cc-covi]][🔑cc-cov] +[![Maintainability][🔑cc-mnti]][🔑cc-mnt] +[![Depfu][🔑depfui]][🔑depfu] + +[🚎dl-cwf]: https://github.com/pboling/rspec-block_is_expected/actions/workflows/current.yml +[🚎dl-cwfi]: https://github.com/pboling/rspec-block_is_expected/actions/workflows/current.yml/badge.svg + +[comment]: <> ( 🔑 KEYED LINKS ) + +[🔑cc-mnt]: https://codeclimate.com/github/pboling/rspec-block_is_expected/maintainability +[🔑cc-mnti]: https://api.codeclimate.com/v1/badges/ca0a12604ecc19f5e76d/maintainability +[🔑cc-cov]: https://codeclimate.com/github/pboling/rspec-block_is_expected/test_coverage +[🔑cc-covi]: https://api.codeclimate.com/v1/badges/ca0a12604ecc19f5e76d/test_coverage +[🔑depfu]: https://depfu.com/github/pboling/rspec-block_is_expected?project_id=5865 +[🔑depfui]: https://badges.depfu.com/badges/79867e590f063376f40b031a1447c215/count.svg + +----- + +[![Liberapay Patrons][⛳liberapay-img]][⛳liberapay] +[![Sponsor Me on Github][🖇sponsor-img]][🖇sponsor] + +<span class="badge-buymeacoffee"> +<a href="https://ko-fi.com/O5O86SNP4" target='_blank' title="Donate to my FLOSS or refugee efforts at ko-fi.com"><img src="https://img.shields.io/badge/buy%20me%20coffee-donate-yellow.svg" alt="Buy me coffee donation button" /></a> +</span> +<span class="badge-patreon"> +<a href="https://patreon.com/galtzo" title="Donate to my FLOSS or refugee efforts using Patreon"><img src="https://img.shields.io/badge/patreon-donate-yellow.svg" alt="Patreon donate button" /></a> +</span> + +</div> + +[⛳liberapay-img]: https://img.shields.io/liberapay/patrons/pboling.svg?logo=liberapay +[⛳liberapay]: https://liberapay.com/pboling/donate +[🖇sponsor-img]: https://img.shields.io/badge/Sponsor_Me!-pboling.svg?style=social&logo=github +[🖇sponsor]: https://github.com/sponsors/pboling + +This gem does ~~five~~, _three sir_, five things. + +1.

So negated matchers are required. A basic set of them are included with this gem, and can be loaded with: ```ruby -require "rspec/block_is_expected/matchers/not" + require "rspec/block_is_expected/matchers/not" ``` This gives you the following matchers: ```ruby -RSpec::Matchers.define_negated_matcher(:not_change, :change) -RSpec::Matchers.define_negated_matcher(:not_include, :include) -RSpec::Matchers.define_negated_matcher(:not_eq, :eq) -RSpec::Matchers.define_negated_matcher(:not_raise_error, :raise_error) + RSpec::Matchers.define_negated_matcher(:not_change, :change) + RSpec::Matchers.define_negated_matcher(:not_include, :include) + RSpec::Matchers.define_negated_matcher(:not_eq, :eq) + RSpec::Matchers.define_negated_matcher(:not_raise_error, :raise_error) ``` #### Example You have a module like this: ```ruby -module MyTasks - def my_rakelib - Rake.add_rakelib("bananas") - end - module_function :my_rakelib -end + module MyTasks + def my_rakelib + Rake.add_rakelib("bananas") + end + module_function :my_rakelib + end ``` You have a spec like this: ```ruby -require "rake" + require "rake" -RSpec.describe(MyTasks) do - describe "my_rakelib" do - subject(:my_rakelib) { described_class.my_rakelib } - it "updates rakelib" do - block_is_expected.to(not_raise_error & - change { Rake.application.options.rakelib }.from(["rakelib"]).to(%w[rakelib bananas])) + RSpec.describe(MyTasks) do + describe "my_rakelib" do + subject(:my_rakelib) { described_class.my_rakelib } + it "updates rakelib" do + block_is_expected.to(not_raise_error & + change { Rake.application.options.rakelib }.from(["rakelib"]).to(%w[rakelib bananas])) + end + end end - end -end ``` ### Integration with RuboCop You'll likely get the following linting error from `rubocop-rspec` if you use `block_is_expected.to ...`: @@ -120,43 +216,43 @@ ## Usage The spec suite for this gem has some examples of usage, lightly edited here. ```ruby -RSpec.describe("TestyMcTest") do - context "errors raised" do - subject { Integer(nil) } - it("can be tested") do - # Where you used to have: - # expect { subject }.to raise_error(TypeError) - block_is_expected.to(raise_error(TypeError)) + RSpec.describe("TestyMcTest") do + context "errors raised" do + subject { Integer(nil) } + it("can be tested") do + # Where you used to have: + # expect { subject }.to raise_error(TypeError) + block_is_expected.to(raise_error(TypeError)) + end + end + context "execution" do + let(:mutex) { Mutex.new } + subject { mutex.lock } + it("can change state") do + expect(mutex.locked?).to(eq(false)) + # Where you used to have: + # expect { subject }.to_not raise_error + block_is_expected.to_not(raise_error) + expect(mutex.locked?).to(eq(true)) + end + end + context "changed state" do + let(:mutex) { Mutex.new } + subject { mutex.lock } + it("can be tested") do + # Where you used to have: + # expect { subject }.to change { mutex.locked? }.from(false).to(true) + block_is_expected.to(change { mutex.locked? }.from(false).to(true)) + end + end end - end - context "execution" do - let(:mutex) { Mutex.new } - subject { mutex.lock } - it("can change state") do - expect(mutex.locked?).to(eq(false)) - # Where you used to have: - # expect { subject }.to_not raise_error - block_is_expected.to_not(raise_error) - expect(mutex.locked?).to(eq(true)) - end - end - context "changed state" do - let(:mutex) { Mutex.new } - subject { mutex.lock } - it("can be tested") do - # Where you used to have: - # expect { subject }.to change { mutex.locked? }.from(false).to(true) - block_is_expected.to(change { mutex.locked? }.from(false).to(true)) - end - end -end ``` -## Switcch to `main` branch +## Switch to `main` branch We recently migrated from `master` to `main` as the default branch.
