KyleTIL in <a href="https://mastodon.social/tags/rspec" class="mention hashtag" rel="nofollow noopener" target="_blank">#rspec</a> ‘describe’ blocks are evaluated when the file is parsed, not when the spec is executed.

postmodernIs there a RSpec matcher to expect that a value exists in an Array of expected values? If not, there should be. I don't like inverting my expect() statement to be:expect(expected_values).to include(subject.thing_i_am_testing) # not idealIdeally it would look like:expect(subject.foo).to eq_any_of(expected_values) # better<a href="https://ruby.social/tags/rspec" class="mention hashtag" rel="nofollow noopener" target="_blank">#rspec</a>

Bradley SchaeferHeads up: rspec-mocks 3.13.3 (released May 1) is a BAD version.There's something wrong with verifying mocks that seems like it causes a problem with mocking methods that take keyword arguments and a block. It seems like the vast majority of mocking works, just some kind of nesting edge case.rspec-mocks 3.13.4 (released May 5) fixes the apparent problemI can't immediately spot what it was, something about the invoking flag<a href="https://github.com/rspec/rspec/compare/rspec-mocks-v3.13.3...rspec-mocks-v3.13.4" rel="nofollow noopener" translate="no" target="_blank">https://github.com/rspec/rspec/compare/rspec-mocks-v3.13.3...rspec-mocks-v3.13.4</a>cc <a href="https://fosstodon.org/@JonRowe" class="u-url mention" rel="nofollow noopener" target="_blank">@JonRowe</a> <a href="https://ruby.social/tags/ruby" class="mention hashtag" rel="nofollow noopener" target="_blank">#ruby</a> <a href="https://ruby.social/tags/rspec" class="mention hashtag" rel="nofollow noopener" target="_blank">#rspec</a>

Jay McGavrenThe output of RSpec's "expect(thing).to recieve(:act).with('foo')" can be a pain to debug if "act" is called with things other than "foo". But TIL combining "expect" with "allow" lists the calls:class Dog def say(sound); end endit "says bark" do dog = Dog.new allow(dog).to receive(:say) expect(dog).to receive(:say).with("bark") dog.say("meow") dog.say("oink") end# Failure message: expected: ("bark") got: ("meow") (1 time) ("oink") (1 time)<a href="https://mastodon.social/tags/Ruby" class="mention hashtag" rel="nofollow noopener" target="_blank">#Ruby</a> <a href="https://mastodon.social/tags/Rails" class="mention hashtag" rel="nofollow noopener" target="_blank">#Rails</a> <a href="https://mastodon.social/tags/RSpec" class="mention hashtag" rel="nofollow noopener" target="_blank">#RSpec</a>

François<a href="https://ruby.social/tags/Ruby" class="mention hashtag" rel="nofollow noopener" target="_blank">#Ruby</a> friends! I have a large number <a href="https://ruby.social/tags/rspec" class="mention hashtag" rel="nofollow noopener" target="_blank">#rspec</a> files. I added Sorbet and I want to have a rough idea if things are good or not before submitting to CI.I'd like to run specs, but let's say 10% of specs within files.Does anyone have a quick something already done? Or should I add a before block and cancel the example if rand > 0.1?

Bradley SchaeferI got to pull out a nice RSpec trick today - using compound expectations.I wanted to check that a method was called with a (rather large) string that had a few different substrings in it.expect(instance).to receive(:method).with( a_string_including("thing 1") & a_string_including(obj.message) & a_string_including("asdfasdfgasd") )The trick here is combining matchers with & There's other ways you might do this, but the test output is really nice this way.<a href="https://ruby.social/tags/ruby" class="mention hashtag" rel="nofollow noopener" target="_blank">#ruby</a> <a href="https://ruby.social/tags/rspec" class="mention hashtag" rel="nofollow noopener" target="_blank">#rspec</a>

Peter SolnicaOne more prompt and we found the culprit 🙃 Now I just asked it to find which specific spec scenario causes our failure and 💥 got it, fixed it, and now I also know that there's state leaking between specs which I want to address in a generic way.

Bradley SchaeferCategory of totally random. OSX Mojave doesn't play nice with `rspec --bisect` anymore because it crashes out when forking, like so:objc[49901]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called.My colleague told me to try running with the environment variable `OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES` and it works.OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES rspec --bisect --seed 1234What is this magic?<a href="https://ruby.social/tags/ruby" class="mention hashtag" rel="nofollow noopener" target="_blank">#ruby</a> <a href="https://ruby.social/tags/osx" class="mention hashtag" rel="nofollow noopener" target="_blank">#osx</a> <a href="https://ruby.social/tags/rspec" class="mention hashtag" rel="nofollow noopener" target="_blank">#rspec</a>

Bradley SchaeferMy favorite RSpec workflow is using the --next-failure option.1. Run your entire test suite to generate the list of failing specs 2. Run `rspec --next-failure` 3. Debug and fix failure, continue repeating step 2 until the test passes and you have a new failure 4. Step 2 succeeds? Run the entire test suite again to ensure none of the fixes broke something elseYou can plow through a lot of broken tests that way. I fixed 50 failing tests in about an hour yesterday by this method.<a href="https://ruby.social/tags/ruby" class="mention hashtag" rel="nofollow noopener" target="_blank">#ruby</a> <a href="https://ruby.social/tags/rspec" class="mention hashtag" rel="nofollow noopener" target="_blank">#rspec</a>
