⚡ From ~30 minutes to ~2 minutes: how a Rails team achieved ultra-fast CI — without rewriting tests.

Parallel RSpec done right, smart workload balancing, PostgreSQL on tmpfs (RAM), and even reconsidering cloud vs physical hardware.

Hi #ruby community I'm looking for other recommendation here https://codeberg.org/codeDude/romodoro-socket/src/branch/main/lib/romodoro/socket/timer/countdown.rb

I''m not sure how to test this with #Rspec

basically the intention is test if the duration is for example 2 seconds the countdown spend 2 seconds.

Could you gimme ideas please?

@kerrick And #RSpec.

Whenever I have to use anything other than #Ruby, I am immediately reminded of how every single testing framework is miles, no, light-years behind RSpec.

Hello #ruby people, How can I test using #Rspec that accept method is receive(triggered). The class is here https://codeberg.org/codeDude/romodoro-socket/src/branch/main/lib/romodoro/socket/timer/command_server.rb#L24

shoulda-matchers가 실제로 당신을 위해 하는 일

shoulda-matchers는 Rails 테스트 코드를 간결하고 가독성 높게 만들어주며, 모델의 계약을 명확히 문서화합니다.

As expected, the ~65% #RSpec test coverage meant that there have been several issues which came up during manual testing, including some very pleasantly head-scratching ones 🧠

hspec uses the same syntax Rspec used many years ago.

Makes me feel nostalgic.

Had to write a spec for some Ruby code recently, turns out instead of function(args).should_equal result one now has to write expect(function(args).to == result.

Oh why?

10591 is the zip code for Tarrytown, NY, the real world setting of Washington Irving's "The Legend of Sleepy Hollow".

This. I've seen a lot of garbage tests this year. I like #RSpec's `xit` shorthand for walking more slowly and deliberately through test scenarios, regardless of whether an agent is involved or not.

TIL in #Ruby #RSpec,

this:

expect(File.exist?(old_file)).to be true

can be shortened to this:

expect(File).to exist(old_file)

expect(File).to exist old_file

Neat!

@postmodern and also, why doesn't #Ruby itself have an opposite direction of .include? method?

[1, 2, 3].include? 1

Like #Rails’ .in?

1.in? [1, 2, 3]

Then the #RSpec would be:

expect(1).to be_in [1, 2, 3]

continuing about collection-based #rspec matchers...

When using `match` and `include` you can let the `it` spec to speak for itself:

```ruby
context 'when one of the values is off' do
it do
expect(subject).to match(
error: 'P',
context: be_a(String).and( eq('S'))
)
end
end
```

I tend to not declare what the `it` is, because it's gratifying see its errors :), usually that's the context blocks are for.

* puns intended
# ruby

@benjamineskola I'd argue that relying on concrete type is something the spec shouldn't care, at least not in #ruby

For example, perhaps it started with a hash, and that was OK, but later on the team want to change the implementation to use something else, like a Struct class.

Error = Struct.new('ErrorStruct', :error, :context)

error = Error.new('Pusher error', 'oops!')

then `be_hash_including` might fail because it's not a hash, is an Struct. Image having 433 spec files :(

#rspec

Lately I've found some resistance to use collection-based #rspec matchers

Checking element by element is technically not wrong:

expect(failure[:error]).to eq('Pusher error')
expect(failure[:context]).to eq('notify_notification_started')

but using `match` & `include` has their advantages:

expect(failure).to match(
error: 'Pusher error'
context: 'notify_notification_started'
)

I can elaborate further if someone ask for it.

Perhaps a blog post about it is needed?
