Agile Testing, Quality Culture, and the Future of QA

What happens when your CI/CD pipeline can’t give you a simple yes or no? Tarek Ziadé, who leads CI/CD on Hugging Face’s Transformers library (and previously built CI at Mozilla), joins David Burns to talk about testing software where the maths changes every time you run it.In this episode:Why green doesn’t mean working: non-determinism, GPU variance and out-of-memory leaks across 500+ model architecturesLiving with 0–500 daily failures out of 13,000 GPU tests, and triaging them with Grafana trends instead of by handSerge, the overnight agent that reproduces failures, builds patches and opens PRs (170 runs, 19 PRs in two months)Catching reward hacking when the agent “fixes” a test by changing the assertionCutting agent costs from $1.50 to under 50 cents a review by moving logic out of prompts and into deterministic PythonA Ruff-style model linter with 58 rules, tiny overfitted models for CPU-only end-to-end checks, and the Model Integration ContractSandboxing agents: separating instructions from data, Bubblewrap, network proxies and a human on the merge buttonPlus the quickfire round: time-to-signal as the most underrated CI metric, why Tarek’s dream job is running coach, and whether AI will ever replace testing.Follow Tarek’s writing on the Hugging Face blog.Subscribe to BrowserStack Talks on Spotify, Apple Podcasts or YouTube so you don’t miss future episodes.

Agile Testing, Whole-Team Quality and AI with Lisa CrispinHow has our understanding of quality changed from the early days of extreme programming, through DevOps, and into the age of AI?In this episode of BrowserStack Talks, David sits down with Lisa Crispin, co-author of the Agile Testing books with Janet Gregory, to talk about whole-team quality and what testers need to thrive next.They cover why DevOps is really just good software development, why small batches still beat big releases, what shift left should actually mean, and how to prioritize risks instead of testing every permutation. Lisa also shares how AI tools can free teams up for more human conversations, how to build a quality culture in remote and hybrid teams, and why communication is the most underrated skill in testing.What you'll learn:- Why continuous integration and small batches are still the biggest hurdles for teams- How to focus on the handful of risks that matter most, and decide whether to test, prevent or monitor them- Where AI adds real value for testing teams, and the trap of forgetting to talk to humans- How feature flags and release strategies make room for exploratory testing- The mindset and skills testers will need over the next five to ten yearsChapters0:00 Welcome to BrowserStack Talks with Lisa Crispin2:30 Whole-team quality: from extreme programming to DevOps5:45 The biggest hurdles: continuous integration and small batches8:11 "I don't have time to test"10:26 What shift left should really mean13:48 Streamlining pipelines and risk-based testing19:09 AI, continuous delivery and the future of testing23:00 Where AI provides genuine value for testing teams27:21 Balancing continuous deployment and exploratory testing30:10 Observability and testing31:17 Quality culture in remote and hybrid teams36:10 Core competencies for testers in the next 5-10 years40:24 Quickfire round49:08 Where to find LisaMentioned in this episode:- Agile Testing, More Agile Testing and Agile Testing Condensed by Lisa Crispin and Janet Gregory- Continuous Delivery by Jez Humble and Dave Farley- Fearless Change and More Fearless Change by Linda Rising and Mary Lynn Manns- DORA (DevOps Research and Assessment) metricsFind Lisa:Website: https://lisacrispin.comLinkedIn: search for Lisa CrispinFollow or subscribe to BrowserStack Talks on your favorite platform so you never miss an episode.

A green build tells you a lot less than you think. Gil Zilberfeld of TestinGil,  trainer and consultant on unit testing, TDD, clean code and API testing,  joins David to unpack what actually makes quality build into software from day one. We cover getting TDD into a ten-year-old codebase that actively resists it, why refactoring is the step everyone quietly drops, what an "80% coverage" target really buys you, and why APIs deserve far more respect than "send a request, check the status code". Then AI: why Gil can't get his coding agent to honour the red step without external scripts and git checks, what self-healing tests really are underneath the magic, and the new ground testers now have to cover — prompt injection, history poisoning, performance, and the token bill. Chapters 00:00 Welcome to BrowserStack Talks 00:31 Meet Gil Zilberfeld, TestinGil 01:06 Video games, flaky tests and testing hype 02:34 Teaching TDD in a legacy codebase that resists it 05:34 Why teams skip the refactor step 11:21 Why TDD matters more in the age of AI agents 16:12 Coverage targets, mutation testing and what really matters 21:03 Good beats perfect: the cost of maintenance 22:30 Giving APIs the respect they deserve 26:59 Complex systems, flaky tests and the elevator analogy 29:27 Breaking flakiness down into something manageable 33:16 Observability and tests as executable documentation 34:57 What do your test results actually mean? 37:09 Self-healing tests: magic, or method? 40:45 Hallucinated edge cases and AI bias in test suites 41:38 Security, performance and tokens: the tester's new remit 44:32 "We don't need QA" and the AI reckoning 48:17 Quick fire round Where to find Guest: Gil Zilberfeld — https://testingil.com Host: David Burns, BrowserStack New episode of BrowserStack Talks every two weeks, where we turn testing pain points into playbooks.

Writing reliable locators is often treated as a rite of passage for automation engineers, and it's just as often the reason pipelines break. In this episode of BrowserStack Talks, host David Burns sits down with Sanjay Kumar, creator of SelectorsHub and TestCase Studio and founder of the SelectorsHub community, to turn testing pain points into playbooks.Sanjay's tools are used by testers around the world every day to save time and cut frustration. We dig into what actually makes element locators fragile, how modern web complexity, Shadow DOMs, nested iframes, and dynamic elements, breaks scripts, and why a clean locator strategy upfront is the difference between scaling your tests and scaling your failures.In this conversation:- The "aha" moment behind SelectorsHub and why beginners had no smart editor for XPath and selectors- Why SelectorsHub generates from the nearest stable element instead of from the top of the DOM- Handling Shadow DOM and iframes that used to cost testers hours of wasted debugging- How TestCase Studio turns recorded actions into plain-English steps — bridging manual testers, analysts, and automation engineers- Self-healing locators and AI hype vs. the discipline of getting the selector right the first time, and why determinism matters- One-click tools for exploratory checks, accessibility, screenshots with URLs, and broken-link scanning- Why development was never the real bottleneck — adoption, maintenance, and human judgment are- A quick-fire round on frameworks, entrepreneurship, and why the world still needs human ingenuity in an AI-driven eraWhether you're a seasoned automation architect or a manual tester moving into low-code automation, this episode is packed with practical takeaways.Explore Sanjay's suite of tools at https://selectorshub.com — and follow Sanjay on LinkedIn and via Testing Daily for the latest from the testing community.Run your scripts across real devices and browsers with BrowserStack to guarantee seamless user experiences.Subscribe to BrowserStack Talks for more conversations that turn testing pain points into playbooks.
