Scarpe, like Shoes before it, tried a variety of display technologies for the Shoes UI app library. Different attempts reached different levels of functionality and maturity.
But it's hard to describe how mature they were. "Shoes3 seemed the most mature, Shoes4 had a good DSL parser but not as good a display library". These are qualitative, very rough judgements. How would you tell? Are things defined by how close to Shoes3 they got? What about clear bugs in Shoes3? What counts as "really" Shoes?
The Shoes Spec, like the Ruby Spec before it, tries to try to spell out these differences and test Shoes implementations. The Shoes Spec isn't the definition -- nobody appointed me the Emperor of Shoes. Instead, it's a place to argue. If we think Shoes should do one thing or another, we can talk through it, write tests and see what current kinds of Shoes do.
Shoes-Spec uses Minitest as its primary testing language, with a Shoes-specific test API for things like finding widgets, clicking buttons and so on. Shoes-spec is also the project of specifying that test API. But each Shoes-compatible display service implements the API methods.
Normally you'll clone the shoes-spec repository in order to use it:
$ git clone https://github.com/scarpe-team/shoes-spec.gitIf you want to test an existing Shoes implementation, you'll find them in the "implementations" directory. Normally you can cd into the appropriate subdirectory and then run "bundle exec rake shoes-spec"
For known implementations, the Shoes-Spec repo does regular test runs to check compatibility.
Shoes-Spec works with a variety of display services. That means, for instance, that your test code and your Shoes application may be running in different processes, or even possibly on different computers. A display service that's designed for that (e.g. Scarpe-Wasm compiles your Shoes app to Wasm and tests with Capybara and a remote browser) will be able to make it work conveniently, for instance by creating proxy objects and shipping Ruby code back and forth.
But there are still some important limitations when writing test code. For instance:
Shoes-spec can work with a variety of display services. That's the whole reason it exists. But it needs to know how to run each one.
The basic unit of Shoes-Spec is a single test -- a Shoes application with a chunk of test code to run against it once it's running.
You can find test cases under "cases" in this repo.
For a single implementation, run "bundle exec rake shoes-spec" in its directory. Some implementations may have more than one way they can be run -- for instance, scarpe-webview can run with Calzini or Tiranti, and it's possible to run with packaged Shoes apps or dynamically.
The latest version of the Shoes-Spec API is found in the Scarpe repository and its classes are documented with Scarpe.
You can find the [top-level methods for Shoes-Spec code](TODO ADD ME HERE) and [parent classes for proxy objects](TODO ADD ME HERE) that will be returned from Shoes-Spec query methods.
