Let's understand in simple flow - 𝐇𝐨𝐰 𝐓𝐃𝐃 𝐖𝐨𝐫𝐤𝐬: 𝟏. 𝐖𝐫𝐢𝐭𝐞 𝐚 𝐓𝐞𝐬𝐭: Start by writing a test for a small piece of functionality. 𝟐. 𝐑𝐮𝐧 𝐭𝐡𝐞 𝐓𝐞𝐬𝐭: It should fail because the feature isn’t implemented yet. 𝟑. 𝐖𝐫𝐢𝐭𝐞 𝐂𝐨𝐝𝐞: Implement just enough code to make the test pass. 𝟒. 𝐑𝐮𝐧 𝐓𝐞𝐬𝐭𝐬 𝐀𝐠𝐚𝐢𝐧: Ensure all tests pass. 𝟓. 𝐑𝐞𝐟𝐚𝐜𝐭𝐨𝐫: Clean up the code while ensuring tests still pass. 𝐖𝐞𝐥𝐜𝐨𝐦𝐢𝐧𝐠 𝐗𝐏 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞𝐬 𝐢𝐧 𝐒𝐜𝐫𝐮𝐦: 𝟏. 𝐄𝐧𝐡𝐚𝐧𝐜𝐞𝐝 𝐐𝐮𝐚𝐥𝐢𝐭𝐲: TDD ensures higher code quality and fewer bugs. 𝟐. 𝐂𝐨𝐧𝐭𝐢𝐧𝐮𝐨𝐮𝐬 𝐅𝐞𝐞𝐝𝐛𝐚𝐜𝐤: Frequent testing provides immediate feedback. 𝟑. 𝐒𝐮𝐬𝐭𝐚𝐢𝐧𝐚𝐛𝐥𝐞 𝐏𝐚𝐜𝐞: Regular testing and refactoring prevent technical debt Integrating TDD from XP into Scrum brings the best of both worlds, leading to robust, maintainable code and a collaborative, efficient team. 𝐄𝐱𝐚𝐦𝐩𝐥𝐞: 𝐈𝐦𝐩𝐥𝐞𝐦𝐞𝐧𝐭𝐢𝐧𝐠 𝐚 𝐒𝐢𝐦𝐩𝐥𝐞 𝐂𝐚𝐥𝐜𝐮𝐥𝐚𝐭𝐨𝐫 1. Write a Test: def test_addition():   result = add(2, 3)   assert result == 5 2. Run the Test: It fails because add function isn’t implemented. 3. Write Code: def add(a, b):   return a + b 4. Run Tests Again: The test passes. 5. Refactor: In this simple example, there's no need for refactoring, but in more complex cases, you might clean up or optimize the code.  𝐏.𝐒 𝐋𝐢𝐤𝐞 & 𝐑𝐞𝐩𝐨𝐬𝐭 𝐂𝐡𝐞𝐜𝐤𝐨𝐮𝐭 𝐭𝐡𝐞 𝐝𝐞𝐭𝐚𝐢𝐥𝐞𝐝 𝐓𝐃𝐃 & 𝐁𝐃𝐃 𝐠𝐮𝐢𝐝𝐞 𝐡𝐞𝐫𝐞 https://lnkd.in/gUFsSFvR #Scrum #agile #scrummaster #agilecoach

𝐇𝐞𝐲 𝐒𝐜𝐫𝐮𝐦 𝐌𝐚𝐬𝐭𝐞𝐫𝐬! 𝐂𝐮𝐫𝐢𝐨𝐮𝐬 𝐚𝐛𝐨𝐮𝐭 "𝐓𝐃𝐃" 𝐰𝐡𝐚𝐭 𝐢𝐬 𝐓𝐃𝐃 ? Let's break down this key concept to enhance our development and testing strategies! ◾ 𝐓𝐃𝐃 (𝐓𝐞𝐬𝐭-𝐃𝐫𝐢𝐯𝐞𝐧 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭): TDD is a software development approach where tests are written before the code that needs to be tested. It promotes better design and maintainability of code by emphasizing a clear, understandable process. ◾ 𝐏𝐫𝐨𝐜𝐞𝐬𝐬: ▪ Write a Test: Start with writing a small test for a new function or improvement. ▪ Run the Test: Run the test, which should fail since the feature isn't implemented yet. ▪ Write Code: Write the minimal amount of code required to pass the test. ▪ Run Tests Again: Run the test again, this time it should pass. ▪ Refactor: Clean up the code, ensuring it adheres to standards. ◾ 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬 𝐨𝐟 𝐓𝐃𝐃: ✅ Ensures code quality and reliability. ✅ Facilitates change and simplifies integration. ✅ Reduces bugs in new features. ✅ Improves design and promotes modular code. Let’s integrate TDD into our Agile processes to elevate our code quality and team collaboration! 🚀 𝐂𝐡𝐞𝐜𝐤 𝐎𝐮𝐭 𝐂𝐨𝐦𝐩𝐥𝐞𝐭𝐞 𝐒𝐜𝐫𝐮𝐦 𝐌𝐚𝐬𝐭𝐞𝐫 𝐓𝐨𝐨𝐥𝐤𝐢𝐭- https://lnkd.in/dABbRxSc #scrum #scrummaster #agilecoach #agile #TDD

Integrating TDD and BDD into Agile development can indeed enhance teamwork and output by ensuring code quality, aligning with business needs, and improving communication among team members. Deep diving into these methodologies can provide valuable insights for teams looking to optimize their development processes further.

Hey Scrum Masters ! Curious about "TDD" and "BDD" in your DevOps talks? Let's simplify these terms! TDD (Test-Driven Development): Developers first write a test for a new function, then the code to pass the test, and refactor as needed.  Repeat for perfection. Benefits of TDD: ✅ Guarantees code quality.   ✅ Serves as live documentation.   ✅ Facilitates easy updates.   ✅ Promotes clean, modular design. BDD (Behavior-Driven Development): Starts with defining expected behavior in simple language, followed by tests, then coding.  Involves everyone from developers to business folks. Benefits of BDD: ✅ Enhances team communication.   ✅ Aligns development with business needs.   ✅ Clears up any confusion. Let’s integrate TDD and BDD into our Agile development to level up our teamwork and output! 📈 Want to deep dive?

Specifically, this means dedicating: 🎯 15% of a team’s capacity to technical debt and refactoring, 🎯 10% of a team’s capacity to bugs, and 🎯 5% of a team’s capacity to explorative spikes (when potentially helpful). A Development Team may, of course, deviate from this rule of thumb depending on the context. Generally, consistently making these allocations will satisfy both the code quality and maintenance requirements of most software applications and build trust among stakeholders regarding the Scrum Team’s capability to deliver valuable product Increments.

Every now and then I stumble upon code or service with limited tests and need to make changes without changing the existing behaviour. In such cases snapshot tests can offer some help to increase the confidence towards the changes. Here's how: 1. Add logs to the code you are changing, focus on outgoing commands and their props and on the return values of your function 2. Run your code with different props and save the logs in file (might need to do it a lot, with different props) 3. Make your changes 4. Compare your logs to the step 1; they should be same, otherwise you have introduced bugs (or found them and fixed 'em!) 5. Remove the unnecessary logs and related files Knowing different approaches to implement refactoring can save you a lot of time. It's like turning from a pigeon to an owl. When you are able to see in the dark you can avoid the obstacles and unpleasant situations. 🐧 Talking about birds; our Technical Agile master class' Early Bird campaign lasts 'til the end of May! There you'll learn different approaches to testing, refactoring and even to code in the dark 🐧 Check it out https://lnkd.in/d4Nqi_5j

#myconf this week got me thinking, and I've decided to use labels like Agile or CI less because most of their meanings have been lost. The #Agile Manifesto is still mostly valid, but it is over 20 years old, and we have access to techniques and technology that weren't available back then. Agile has also been hijacked by companies and frameworks pushing methods that are anything but agile, so when someone talks about Agile, it's impossible to know what they mean. I've been using the term to refer to "mostly what's in the Agile Manifesto, but with modern tools and technologies where that's better", which isn't any better. I will talk about specific techniques and practices instead to avoid confusion. #ContinuousIntegration and #ContinousDeployment have become synonymous with having a pipeline that runs the tests before a PR can be merged. Everyone is doing _that_, but almost no one is doing CI or CD. I've been guilty of conflating them myself, so I'm just going to stop using them - constantly stating that I mean "real" or "proper" CI when discussing development flow just makes me sound like an ass. Many people think you are practising #TDD as long as you write tests. I've also seen comments that indicate the person writing them believes that TDD is only about writing tests and almost no implementation. TDD uses tests to drive implementation; it's as much about the quality of the code and resulting architecture as it is about the tests. I will talk about test-first and incremental development instead. You will probably still catch me using these terms, but I will try to avoid them. -- Dušan veverkolog over at Unsplash thought this was an agile squirrel.
