3. What we used to do
Develop
Test

4. What we did for a while

5. What we are doing

6. What they tell us to do
TDEESVT

7. What some are doing Test Develop Test Test Develop Test

8. For each Acceptance Criteria Create a failing integration test
Create a Requirement
Refactor
Create a failing
unit test
Make the unit test pass
TDD
Define Acceptance Criteria
For each Acceptance Criteria
Create a failing
integration test
Make the
integration test pass
Demonstrate
Working Software

9. Expressing Desirements
User Stories represent needed conversations
As a <application role>
I want <some feature or behavior>
So that <I get some benefit>
Scenarios document the conversation took place
Given <some initial context>
When <this happens>
Then <this should be the result>
Desirements
Things we wish software did.
But it doesn’t. Yet.

10. 1, 2, 3 [TestMethod] public void
Total_Should_Be_1_When_1_Product_Added() {
var cart = new ShoppingCart("TEST");
cart.AddItem(new Product("SKU"));
Assert.AreEqual(1, cart.TotalItems); }
Given
When
Then

11. Early attempts at cleaner test code.
Code Now
Basic AAA and GWT
Early attempts at cleaner test code.

12. Gherkin Domain Specific Language Business Readable
Interpreted by machines
A model for software requirements
2 Purposes
Feature documentation
Automated test harness
pic by me

13. Steps Feature: Some terse yet descriptive text
In order to realize a named business value
As an explicit system actor
I want to gain some beneficial outcome
Scenario: Some business situation
Given some precondition
And some other precondition
When some action by the actor
And some other action
Then some testable outcome is achieved
And something else we can check
# language: no
Egenskap: Summering
For å unngå at firmaet går konkurs
Må regnskapsførerere bruke en regnemaskin
for å legge sammen tall
Scenario: to tall
Gitt at jeg har tastet inn 5
Og at jeg har tastet inn 7
Når jeg summerer
Så skal resultatet være 12
Steps

14. ATDD from the outside in
Code Now
ATDD from the outside in
The new look of software testing

15. How these tests look in a Sprint
Other validation techniques start about here
Pass

16. Some gross generalizations
mostly unnecessary UI
brittle, but possible
View
Model
requirement specs here
Controller / Presenter
mostly unit
Domain
Entities
and some here, too
Commands
Value Objects
Repositories
Services
Data Access (EF)
hopefully minimal
mythical

17. Developer Tests focusing on behavior
Code Now
1, 2, 3 a little lower down
Developer Tests focusing on behavior

18. Another pyramid GUI Behavioral Acceptance Tests Unit Tests
As little as possible As much as necessary
At least one per requirement
At least one per class or module
