I came up with this yesterday while running my agile acceptance testing workshop for a client.

The next meeting of the UK agile testing user group is on the 3rd of August in central London. Here are the details of the talk:

Dan Leong on Clean Acceptance Tests

This presentation discusses how our agile team renewed our focus and understanding of our acceptance tests when the team members changed. Our group found some core shared values in the context of acceptance testing which we expressed in the style of the agile manifesto. We then looked at our existing tests to find bad test smells that we could learn from. The whole exercise was a good experience and we encourage you to try something similar in your teams.

Dan Leong is a team lead at Sky Network Services, where they have been using agile/XP techniques for over 4 years to deliver the company’s broadband and voice provisioning system. He has over 10+ experience working in companies ranging from small .com start-ups to global advertising and media companies. Like the rest of us, he’s trying to figure out how to do things better.

There is a discussion on the UK agile testing mailing list on driving the development of an administrative application with BDD. It illustrates a problem that many teams have, so I’ll post my response here as well.

Although we have a long way to go things are going OK at the moment and we feel it is bringing some real focus to the development process. However a lot of the early stories are largely admin type CRUD – for
example functionaility to set up user defined entities and their user defined properties within the system and to provide a mechanism for relating these entities to each other
…
Does anyone have any advice about how to write tests for this sort of stuff or any experiences in starting out with BDD they can share.

CRUD is not a user story, it’s a screen. It’s not a business function, but implementation detail. Why do the business users need a particular CRUD screen? (I know it sounds as a stupid rhetorical question, but I’m serious) What does it allow them to do?

Often you don’t need to implement an entire CRUD screen and deliver them one by one. Sometimes there is value in releasing two screens that allow you to set a subset of properties but together they bring value. You can then automate these tests through the UI and use the CRUD screens, but that will be hidden in the automation layer. Say for example that we have a risk report that lists users and their card numbers:

Scenario: Only regular customers with a specific risk category and 
              card type show up in risk reports
Given the following users
|name| type| card type| card number| risk category|
|Mike |VIP | Mastercard |53111 11111 11111 1111|X|
|Tom |VIP| Visa |41111 11111 11111 1111|Y|
John |Regular |Mastercard |51111 11111 11111 1111|X|
|Steve |Regular |Mastercard |52111 11111 11111 1111|Y|
Then the risk report for Mastercard and category X contains the following data
|John | 51111 11111 11111 1111|

This could, for example, invoke the user CRUD to save a user name, type and risk category and a completely different CRUD to save card details for that user. Any other information that would go on that CRUD (addresses, card expiry dates etc) aren’t part of this story or criteria because they are not important for this particular report.

Start with the outputs, the reports that the system produces, instead of data entry operations. this ensures that you have the data you need to produce the reports at the end, and that you don’t have superfluous data that nobody really cares about. if you don’t do that, the resulting data schemas are often overcomplicated and contain many things that simply aren’t used at the end at all.

The Unite union (of the let’s screw BA travellers for several weeks every few months fame) created a
Facebook group to stop jobs in the technology department being outsourced and offshored at Guardian News Media Ltd, publisher of the Guardian, the Observer and guardian.co.uk. According to the group web site, the board of Guardian News Media is meeting tomorrow to make a decision on outsourcing a large part of their IT department.

Without taking a position on who’s right or wrong in this case, I’m very interested in how this whole thing is going to play out. A recent major rewrite of their flagship web site is one of the most publicised apparently successful IT projects in the UK. Continue Reading »

Creating an Executable Specification from existing manual test scripts might seem as a logical thing to do when starting out with Specification by Example and Agile Acceptance Testing. Such scripts already describe what the system does, and the testers are running them anyway, so automation will surely help. Not really — this is in fact one of the most common failure patterns.
