Slides from the Feature Mapping workshop run at Agile Testing Days 2018 in Berlin. Feature Mapping helps teams collaboratively write higher quality executable specifications. Writing good acceptance criteria is one of the keys to effective software delivery. But it’s hard. In this workshop, you will learn about Feature Mapping, a simple but powerful technique that helps teams understand requirements at different levels and leads them naturally to write great executable specifications. Building on Jeff Patton’s Story Mapping, Matt Wynne’s Example Mapping, and other techniques, Feature Mapping is an excellent way to build a deep shared understanding of a story's requirements and to clear a path to a smooth implementation of automated acceptance tests. This workshop will be structured in two parts. The first will present the principles behind Feature Mapping, and the BDD requirements discovery process in general, and walk through an example of building a feature map. During the second half of the workshop, participants will work in groups of 6 to use Feature Mapping to go from a user story with a few high-level acceptance criteria, to executable specifications that could be implemented directly in Cucumber.

“Behaviour Driven Development”
Collaborate to

language to build
a shared

And automation
that provides
fast and relevant
feedback
To deliver

14. We question rules to find examples
We challenge examples to find counter-examples
We explain counter-examples with new rules
We start with the rules we know about

Four Principles

A Simple
Feature Map
“Sally is assigned a high priority review task for a
suspicious transaction. She knows she won’t be able to
complete it today, so she delegates it to her colleague
Doug. Doug sees the review task appear in his task list,
and Sally should see the task in her ‘Pending others’ list”
Delegate a review task
As a busy regulatory supervisor
I want to be able to delegate some of my review tasks
to other users
So that the tasks will be processed in a timely manner

17. Delegate a review task
As a busy regulatory supervisor
I want to be able to delegate some of my review tasks
to other users
So that the tasks will be processed in a timely manner
The one where Sally

task
Sally assigns the
task to Doug
=> The task should
not appear in Sally’s
task list

be visible in Doug’s

appear in Sally’s
Pending Others list
Start with a happy path
or a known rule

Feature Maps
and Gherkin
Feature Maps lead naturally to good
quality Gherkin

30. The supervisor is
warned if the
delegate is absent
The one where Doug
is on holidays
Sally is assigned a
Suspicious
International
Transfer review task
Sally tries to
assign the task to
Doug
=> Sally is warned
that Doug is on
holidays
Doug is on holidays
this week
Scenario: The one where Doug is on holidays
The supervisor is warned if the delegate is absent
Given Sally has been assigned a 'Suspicious International Transfer' review task
And Doug is on holidays until next week
When Sally tries to delegate the task
Then Sally is warned that Doug is on holidays

31. Let’s give it a try!

32. Key Take Aways

33. Feature Mapping
Collaborative Iterative Exploratory
A requirements discovery practice that is…

34. Feature Mapping
Breadth Depth Context

35. Feature Mapping
More precise than
free-form
acceptance
criteria
Faster than Gherkin Easy to automate
