The document discusses the importance of testing code through test-driven development (TDD) and behavior-driven development (BDD). It explains that TDD involves writing tests, watching them fail, making them pass, refactoring, and repeating. BDD is more complex and involves business analysts, developers, and stakeholders specifying desired behaviors as user stories. The document encourages writing unit tests because it allows for quick code changes with confidence, helps understand code design, and documents expected behavior, though it takes time initially.

Testing in a continuous delivery world - XP Days UkraineWouter Lagerweij
Hey, do you remember when everyone was asking what the role of the tester would be in an agile team? It’s happening again!
A team that takes on the challenge to release their every commit certainly will take testing seriously. It will need to evolve new ways of testing. It will have new dynamics of testers working with developers.
In this talk we’ll look at how continuous deployment changes the dynamics of an agile team. How quality moves even more to the center of the stage. How that changes the role of the tester once again. And of developers, too. How to put the customer center stage again. And how that, too, has testing competencies at its core. And we’ll not forget DevOps, and how monitoring can be a continuous testing strategy.
Shyam Sunder discusses how his team changed their testing approach to align with the overall Project Activation timeline and came up with the Lego Test method. Presentation at Test Leadership Congress 2018.

Lightening Talk I gave at Inaka in April 2014.
I was in charge of investigating test-driven development for our iOS mobile team. Since I realized it was such a big concept, after having gathered enough information and having played with it enough, I decided to introduce my fellows on the topic by presenting it in a formal talk with slides. The aim was teaching them a different way of developing, which, for us, at that moment, was completely new and controversial.

In his recent book, Clean Agile, Robert C "Uncle Bob" Martin chooses Extreme Programming (XP) for the basis of his explanation of Agile because "of all the Agile processes, XP is the best defined, the most complete, and the least muddled."
So why is it that in my professional life I only hear us speaking about Agile in terms of Scrum, Sprints, and possibly Kanban? Often I mention XP and people are not sure what I mean. Am I sure myself?
Coined in 1999 by Kent Beck and Ward Cunningham, XP has been with us for twenty years, but may of its practices have been with us for much longer. Many of them will be familar to you, but did you know they came from XP?
This talk aims to take us back to what XP is, how it fits in the Agile world, how it sits alongside other methodologies, and why, like Uncle Bob, I believe it is the best defined methodology, and what we should all be talking about.
The talk is based on a heavily refactored talk that Mike gave previously at Agile on the Beach conference, updated for 2020.

2. Understanding BDD and TDD
• Test Driven Development in simple form is :
Write your tests.
Watch them fail.
Make them pass.
Refactor.
Repeat.
3. BDD – Behavior Driven
Development
• BDD – Behavior Driven Development on the other hand is a
little more complex. It is more of a team work.
• It is more of how a desired behavior should be specified.
• In this concept, Business Analysts and Developers should
specify behaviors in terms of “User Stories”.
• Involving the stake holders in the implementation process
through outside-in Software Development.
• Now we have our own “Jasmine” which helps us test our
JavaScript code in a more TDD way of style.
• For more information on BDD learn here (Wiki is the
best!)http://en.wikipedia.org/wiki/Behavior-
driven_development
4. Real Code! Wohoo….
• If you're all into Rspec, you’ll see Jasmine Framework very
similar.
describe('JavaScript addition operator', function () {
it('adds two numbers together', function () { expect(1 +
2).toEqual(3);
}); });
• “Describe” and “it” functions – Take two parameters a string
and a function.
• Inside “it” block – Write setup code you need for your test.
• Ready to write the actual test – Start with the “expect”
function.
6. So why the Test??
• Unit tests and test-driven development (TDD) have so many
hidden and personal benefits as well as the obvious ones, you
just can't really explain to somebody until they're doing it
themselves.
• Unit tests allows you to make big changes to code quickly.
• You know it works now for sure (because you’ve run the
tests!)
• When you follow TDD no code is considered as
bad/buggy/annoying.
• Unit test helps you to understand the design of the code that
you’re working on.
7. • “One test is worth a thousand expert opinions”. Imagine you
writing the test and saying with confidence (that damn thing
works!)
8. • Good unit tests can help document and define what
something is supposed to do
• Unit tests help with code re-use. Migrate both your
code and your tests to your new project. Tweak the code till
the tests run again.
• Writing unit tests can consume a lot of time in the beginning
but it’s so much worth it.
Sold!
You know it’s good for you, then why not start testing your code.
