This document discusses test-driven development (TDD) and acceptance test-driven development (ATDD). It defines TDD as a process of first writing a test, then code to pass the test, and refactoring code while relying on tests. ATDD helps ensure correct external features by defining tests for customer requirements. The document outlines benefits like reduced bugs and increased confidence. It also discusses tools that support TDD/ATDD like unit testing frameworks, FitNesse for acceptance tests, continuous integration, and code coverage tools.

"Software architecture...Yes, on tests!" by Annarita De Biase, Miro Barsocchi, Camillo Quatrini
How many times have you thought it was unuseful to spend time in order to make tests as much usable, maintainable and automated as possible? This question is the nightmare of developers and testers. Here, we would like to introduce a new architecture that, potentially, is able to reach a general agreement, by using technologies you all know but strutctured in a different way, that is using microservices. We will talk about previous good and bad experiences, our current solution and a lot of kittens.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.

Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. Software Quality
• A definition in Steve McConnell's Code
Complete divides software into two pieces:
internal and external quality
characteristics.
• External quality characteristics are those
parts of a product that face its users,
where internal quality characteristics are
those that do not.
5. TDD in summary
A. First we write a test.
B. Then we write code to make the test
pass.
C. Then we find the best possible design for
what we have - refactoring (Relying on the
existing tests to keep us from breaking things
while we are at it)
6. TDD goals
•
TDD is a technique for improving the
software’s internal quality
Well-written code
• Good design
• A balanced division of responsibilities
• Without duplication (clones)
• Smooth evolution
• Maintainability
7. ATDD goals
• Acceptance TDD helps us keep our
product’s external quality on track by
giving it the correct features and
functionality.
• the system should meet what the
customer actually need.
8. Both sides of quality
************************************
• Then, we need to learn how to build the
thing right - TDD.
• Also, we need to learn how to build the
right thing - ATDD.
10. Meeting needs with acceptance
TDD
Traditional way of
adding features
• Requirements – doc
• Implementation – sc
• Test design – tc
• Developer Test – rep.
• Acceptance test
Acceptance TDD
• Requirements – doc
• Test design – tc
• Implementation – sc
• Developer Test – rep
• Acceptance test
11. What is the difference?
• With ATTD we translate a requirement into a set
of executable tests and then do the
implementation against the tests rather than
against the developer’s interpretation of a verbal
requirement.
• Rather than working off of arbitrary requirements
documents, in acceptance TDD we strive for
close collaboration and defining explicit,
unambiguous tests that tell us exactly what it
means when we say a feature is “done.”
12. Close relationship
• TDD and acceptance TDD often go hand
in hand. On the system level, we run our
development process with acceptance
TDD; and inside the implementation step
of each feature; we employ TDD.
13. Benefits?
• No more long debugging sessions
– Each test case corresponds to a feature of the
system
– Test cases support refactoring
• More time for other stuff
– Reduce time of debugging sessions
– Reduce time fixing bugs
– Reduce rework due to misunderstandings
regarding requirements
14. Benefits?
• Feeling confident with my work
– The better your test suite is, the better the
quality of your code and the more confident
you can be about any changes you make. The
more confident you are about the changes
you make, the more changes you dare to
make. The more changes you make, the
better your internal quality becomes, the
easier it is to write tests for your code, and so
on. (a virtuous cycle)
15. Build it right: TDD
• TDD is a development and design
technique that helps us build up the
system incrementally, knowing that we’re
never far from a working baseline.
• A test is our way of taking that next small
step.
17. Build it right: TDD
• Test-Code-Refactor
The term refactoring is used to better
communicate that the last step is about
transforming the current design toward a
better design.
18. First we write a test
• We are writing a test. Also, we are making
design decisions:
– We are designing the API—the interface for
accessing the functionality we’re testing.
– The test case that we design will be the first
“client” of the functionality that we are going
to implement.
– One of the fundamental lessons in designing
an interface is that we only evaluate a design
effectively and objectively when we try to use
it.
19. Then we write just enough code
• The second step of the TDD cycle is to
write just enough code to make the test
pass.
• You’re satisfying an explicit, unambiguous
requirement expressed by a test.
20. And then we refactor
• Take a step back, look at our design, and
figure out ways of making it better.
• It is all about keeping your software in
good health—at all times.
• Refactoring is about applying refactorings
on code in a controlled manner
21. Keeping code healthy with
refactoring
• “a disciplined technique for restructuring
an existing body of code, altering its
internal structure without changing its
external behavior” : Martin Fowler
22. Refactoring Example
• Replace Inheritance with Delegation
– Motivation: A subclass uses only part of a
superclass interface or does not want to
inherit data
– Summary: Create a field for the superclass,
adjust methods to delegate to the
superclass, and remove the subclassing.
24. Refactoring Example
•
Mechanics
1. Create a field in the subclass that refers to
an instance of the superclass. Initialize it to
this.
2. Change each method defined in the
subclass to use the delegate field.
3. Compile and test after changing each
method.
25. Refactoring Example
•
Mechanics
4. Remove the subclass declaration and
replace the delegate assignment with an
assignment to a new object.
5. For each superclass method used by a
client, add a simple delegating method.
6. Compile and test.
26. Refactorings alter internal
structure
• Many of the refactorings are very low-level
– rename method
– Rename variable
• Low-level refactorings are the fundamental
building blocks to achieving larger
refactorings
– Moving the responsibilities around in your
code
– Introducing or removing an inheritance
hierarchy
27. Refactorings preserve behavior
• whatever transformations you apply to the
existing code, those transformations
should only affect the code’s design and
structure—not its externally visible
behavior or functionality.
– Renaming a method that is part of a class’s
public interface - ???
– how can we be sure that our refactorings
haven’t changed the code’s external
behavior? - ???
30. Acceptance TDD
• Acceptance tests are indicators of the
completion of a requirement or feature.
• When all acceptance tests for a
requirement or feature are passing, you
know you’re done.
31. Advantages of ATDD
• Close collaboration
– Seeing concrete, working software
– Building trust and confidence
– Customer in control
– Evolving a shared language
• Tests as a shared language
– Tests as specification
– Specification by example
32. Tools for test-driven
development
• Unit-testing with xUnit
– Provides supporting code for writing unit tests,
running them, and reporting the test results.
• Test frameworks for acceptance TDD
– Tools for enhancing collaboration in software
development. (Fit and Fitnesse)
– They enable customers, testers, and programmers to
learn what their software should do, and to
automatically compare that to what it actually does
do.
– They compare customers' expectations to actual
results.
33. FitNesse
• FitNesse is a lightweight, open-source
framework that makes it easy for software
teams to:
– Collaboratively define Acceptance tests -- web
pages containing simple tables of inputs and
expected outputs.
– Run those tests and see the results
• http://fitnesse.org/
34. Tools for test-driven
development
• Continuous integration and builds
– On the one hand, running the full test suite
often takes too long (several minutes—even
hours) for a developer to wait for the green
bar.
– On the other hand, most of the tests are
unlikely to have been affected by the
developer’s recent changes
37. Continuous Integration references
• More about the philosophy behind
continuous integration and the associated
tools:
– http://www.martinfowler.com/articles/continuo
usIntegration.html.
– http://www.jamesshore.com.
38. Tools for test-driven
development
• Code coverage
– In short, code coverage is a measurement of
how thoroughly our automated tests exercise
the production code and its source code
statements, branches, and expressions.
– http://www.javaranch.com/newsletter/200401/Intro
39. Tools for test-driven
development
• Code coverage
– This can be especially helpful when a team is
just starting to write unit tests or adopting
TDD, because it helps pointing out areas of
the code base that are not getting tested as
thoroughly as other parts of the code.
