    Cuba takes help from a lot of other technologies to bring the best of everything. For example, the responses in Cuba are the optimized version of the Rack responses. The templates are integrated via Tilt and testing via Cutest and Capybara.

  • Building GitHub with Ruby on Rails
    11 projects | news.ycombinator.com | 7 Apr 2023
    Even as a much smaller team, building Heii On-Call [0] as a lightweight alerting/monitoring/on-call rotations SaaS based on Ruby on Rails has basically been a pleasure!

    And as the article highlights, perhaps the key reason for smooth deployments and upgrades is that the CI testing story is so, so good: RSpec [1] plus Capybara [2] for us. That means we have decently extensive tests of just about all behavior. The few small Rails and Ruby upgrades we've done have gone quite smoothly and confidently, with usually just a few non-Rails gem dependencies needing to be manually updated as well.

    The "microservices" story is where we've pulled in the Crystal programming language [3] to great effect. After dabbling with Go and Rust, we've found that Crystal is truly a breath of fresh air. Crystal powers the parts of Heii On-Call that need to be fast and low-RAM, specifically the inbound API https://api.heiioncall.com/ and the outbound HTTP(S) prober background processes. I've ported some shared utility classes from Ruby to Crystal almost completely by just copy-and-pasting ___.rb to ___.cr; porting the tests for those classes was far more onerous than porting the class code itself. (Perhaps another point of evidence toward the superiority of RoR's testing story...)

    The front-end story is nice but just a bit weaker. Using Hotwire / Turbo successfully, but I have an open PR to fix a fairly obvious stale cache bug in Turbo [4] that has been sitting unloved for nearly a month, despite other users reporting the same issue. I'm hopeful that it will get merged in the next release, but definitely less active than the backend side.

    For me, the key conclusion is that the excellent Ruby on Rails testing story is what enables everything to go a lot more smoothly and have such a strong foundation. I'd be curious if any GitHubbers can talk more about whether they too are using Rspec+Capybara or something else? Are there internal guidelines for test coverage?

  • Minitest vs. RSpec in Rails

    Since the Capybara library drives the underlying tests, Minitest also has the same syntax.

    11 projects | dev.to | 3 Jun 2022
    The nice thing about partial templates is that templates are unit-testable with View specs (or similarly in Minitest) and the rendered output can even be verified using Capybara matchers.

    To piggyback: This would be a type of browser test, so you would want to use something like Cypress (https://github.com/testdouble/cypress-rails) or Capybara (https://github.com/teamcapybara/capybara). RSpec has a good integration with Capybara. Cypress is JS-based so it will require some additional config.

    Grape is a REST-like microframework written in Ruby programming language. Grape is also considered among the best ruby frameworks and can be used to run on top of Rack or can be used to complement the existing web application frameworks such as Sinatra or Rails. The latter can be done through the DSL-based REST-API for communication. The Grape ruby web framework facilitates efficient and meaningful APIs working in the web application domain.
    6 projects | dev.to | 11 Mar 2024
    Grape’s support extends to standard conventions, multiple format support, content negotiation, versioning, etc. The complete guide to Grape to develop REST-APIs, test the API and analyze the performance metrics is available on its official GitHub page.
