a small working example

[mulderp]

Hi,

just as an idea to use a working example in the README

It's maybe easier to see that such things as headers, etc. can be tested.

Well... this commit is not rocket science, but maybe would be interesting for some or the other. Actually in combination with Capybara this might open up new ways for testing.

Thanks, Patrick. Why do you prefer this example to the previous one?

[mulderp]

Yes, I was just starting on learning about Rack in general. From my understanding, there are 3 types of rack app's used:

• lambda function with one static response
• Sinatra apps
• Rails apps

When learning on Rack, the lambda function seems to be the standard use case, which I was thinking that showing this in an example might be nice.
After some weeks, I see that the config.ru parsing also provides enough hints, on how to test apps with Rack test.
Not sure, if my explanation makes sense. Thanks for you feedback/interest in any case.

As a reference, there is another PR to add require "test/unit".
#74

@junaruga I would actually like the improved example as well.
@mulderp are you still available and could you rebase your PR on the latest master to fix the merge issue?

[junaruga]

@scepticulous I would prefer the improved example as well. I agree with you. If some people like other use cases (types)' examples in the future, I want to split the example section from README, and link from the README to sample/*.rb.

[mulderp]

@scepticulous thanks for the ping - unfortunately, I am not working with Ruby anymore for some years.
I think it makes sense that I close the PR and you can go ahead and open an updated one.
