I am looking at the source code of crystal/src/spec/example.cr and I would love to have access to the Example’s description field from my specs. People may be asking why would you want to do that ? The reason is that I have a lot of golang specs in the form of t = {text: "thing to be tested", erro…

Let say I want to test some math operation it "1 + 2" do expr = "1 + 2" mytest(expr) end I would like to do this it "1 + 2" do expr = get_description_of_this_spec() # expr should no hold "1 + 2" mytest(expr) end

Maybe the spec runner could yield the instance of Spec::Example to the block. This might even have been proposed before, I’m not sure. But it currently doesn’t work. A simple workaround would be to use a helper method to build the example: def it_exp(description, file = __FILE__, line = __LINE__, &…

But what do you want to do with the description? In your example you pass it to a method, but what does the method do? We need to know the exact use case. For example if you need the description to show it when the spec fails, that’s already being done by the spec runner. Then, there’s no eval in Cr…

Thanks, great, exactly what I need.

I guess a use case would be some kind of parser or anything that somehow handles a string. Then it would make sense to use the same string for both the description of the spec as well as the sample being tested. This use case is present in the compiler specs. it_parses from parser_spec.cr is pretty…

I need this. I need to use Spec::Item.description for the name of each test’s snapshot file. Otherwise each test will have 2 copies of the description text. bad: it "lists some JSON for user" do res = process_request req res.body.should match_snapshot "Http/Posts/List/lists some JSON for…

Sorry, I don’t follow what you need the description for. Can you show an actual example of what you want to do?
