The Given, When, Then framework

Testing RSpec

Hi,

Is the Given, When, Then framework, the user story, the acceptance
criteria or both?

From my talk at railsconf:
http://en.oreilly.com/rails2008/public/schedule/detail/2055

=============================================
Story: measure progress towards registration goals
As a conference organizer
I want to see a report of registrations
So that I can measure progress towards registration goals

Scenario: one registration shows as 1%
Given a goal of 200 registrations
When 1 attendee registers
Then the goal should be 1% achieved

Scenario: one registration less than the goal shows as 99%
Given a goal of 200 registrations
When 199 attendees register
Then the goal should be 99% achieved

The story and the text before the first scenario is the User Story as
we’ve always known it in XP.

The Scenarios are automated, and represent acceptance criteria.

Make sense?

Cheers,
David

Certainly does. I am automating the tests (only tester on my project),
but I have asked the BA’s not only to write the story then, but also
give the scenarios. I do a lot of re-work on the story though.

Should I just be asking just for the story and for me to add the tests
(Given, When, Then)

I also asked them for negative scenarios.

The ideal situation is that you and the BA’s sit down together to work
this out. The goal here is group communication rather than one role
owning part of the communication.

Short of that, there is no one right way to do this. Perhaps they
provide stories, you add scenarios as demonstration, they add more
scenarios for thoroughness, etc.

What is a “negative scenario”?

Thanks for getting back.

I have been asked that twice in 2 days!

In the use-case world they have negative or mis-use cases.

These cases desribe forbidden or wrong input into the system
that has not been specified.

…
When the user enters alpha characters into the DoB field
Then an error message appears informing him of this
And gives an example of a correct input.

Got it. For me, that is positive :slight_smile: But I get the idea.

Thanks
