   PBT – A property-based testing library for Ruby▲196

   Hello HN, I introduce a property-based testing tool for Ruby. Ruby's ease of test-writing and rich ecosystem are widely acclaimed. However, property-based testing is not as widely used as in other languages such as Haskell or Elixir, and I think this is because there is no de facto testing tool. This gem currently not only has the basic functionality of stateless property-based testing but also has the following features: - Support verbose mode that allows you to see its shrinking procedure and algorithms. - Support several concurrency/parallel executions of each test. As of now,…

    I built a tool to get instant test results▲96

    I got sick of the old software development loop: Change code -> Run tests -> wait -> wait some more -> look at failures. I decided to build a tool that will enable you to: Change code -> look at failures. No wait time, no explicit test running. Under the hood: - Runs the whole test suite and collects code coverage per test. - For each auto file save, analyzes the changes on the tests. - Runs changed tests in the background. - Display results, the loop time from change to test results is approx 250ms. Instead of: code -> alt+tab -> arrow up -> rerun all the tests -> wait ... -> test results…
