What's new in Playwright 1.62: MCP in the box, isolated retries, and a patch you should not skip tldr: The MCP server and a CLI now ship inside the Playwright package, so npx playwright mcp runs with nothing else installed. Retries get an 'isolated' strategy that separates a flaky test from a tes Sandeep Panda July 31, 2026 · 12 min read Smoke testing in 2026: what it is, examples, and when to automate it tldr: A smoke test is a fast, shallow check that a build's most important paths work at all. If the smoke test fails, the build is rejected on the spot, before anyone spends time on deeper testing. Th Syed Fazle Rahman July 13, 2026 · 8 min read Spec-driven development needs a testing layer. Here's what most teams skip. tldr: Spec-driven development (SDD) has you write a detailed spec, then an AI agent turns that spec into code. It is the serious answer to vibe coding.

It is the final check before release, where the people who will actually use the software confirm it does what they need, not just what the spec said.

Here's the part I didn't go deep enough on: the FDE pod is our best product researcher. Every day, our Forward-Deployed Engineers run tests against real customer applications. They see what the AI gets right. They see where it struggles. They see the gap between "test passed" and "this actually works." That gap is where the product Syed Fazle Rahman February 19, 2026 ShortThe testing industry spent fifteen years solving the wrong problem. CSS selectors break? Use data-testid. Data-testid is too coupled? Use aria-labels. Aria-labels change? Try XPath. XPath is fragile? Add a custom attribute. Custom attribute got refactored? Write a more resilient selector strategy. More layers. More conventions. More things to maintain. Nobody stopped to ask: why are we pointing Syed Fazle Rahman February 19, 2026 ShortSomeone asked me last week: "Can I export my Bug0 tests as Playwright scripts?" No. And we're not building that. Not because of lock-in. Because exporting a script misses the point entirely. A Playwright script is a snapshot. It captures what worked at that exact moment — those selectors, that layout, that flow. The second your UI changes, it's stale.

Your team ships 3x faster. QA didn't keep up. Cursor, Copilot, and Claude Code made development 3x faster. QA is still where it was two years ago. Every sprint, the gap grows. Testing becomes the reason you can't release on Friday. Your test scripts break faster than you can fix them. You tried. You wrote tests. They broke when design changed a button. Your engineers spent a week fixing selectors instead of building features. That's not a testing strategy. That's a tax. Hiring a QA engineer costs $150K. And takes 3 months. By the time you find someone, onboard them, and get coverage, you've shipped 30 releases untested. Most teams just ship and hope. You know how that ends. An engineer builds the tests. AI keeps them working. Nothing slips through. Full end-to-end test coverage without writing a single script. Every failure reviewed by a real person. AI test generation. Give us access to your staging environment. That's it. Your FDE analyzes your app, plans coverage, and generates Passmark-based test scripts. Real Playwright and TypeScript. You do nothing. Self-healing execution. Tests adapt when your UI changes. 0% flake rate. Every run produces video, logs, and AI analysis. Runs in the cloud, on every PR. Human-verified results.

Book a Demo What engineering leaders say. “Bug0 is the AI QA platform behind Prospyr, the practice management software for aesthetics clinics. It tests our web app continuously and points us to exactly where the app broke when something fails. We catch issues early instead of in production, which keeps a HIPAA-compliant product stable.” Greg KopyltsovCo-founder and CTO, Prospyr “Bug0 is the closest thing to plug-and-play QA testing at scale. It's helped us catch multiple bugs before they made it to prod.” Steven TeyFounder, Dub “We build healthcare compliance software, so accuracy and reliability are non-negotiable. Bug0 provided us with an AI-based QA layer without adding headcount or another tool for my team to learn and manage. The tests run against all of our QA instances on a regular basis, providing us with a level of coverage and confidence that previously required many resources. We can focus our team on new development and real issues, and that's the part I care most about.” Derek WalkerCompliance Products and Solutions Manager, Genzeon “We plugged Bug0 into our CI and had our critical flows covered within a week. Like having a proactive QA engineer reviewing every deploy.” Karim VarelaCTO, Space Runners “Bug0 is the AI QA platform behind Ferra, AI estimating software for steel construction. AI-based testing and execution with a forward deployed engineer who verifies every result, so we catch real bugs before production instead of chasing false positives. We see exactly where things broke, and we ship with confidence.” Michael GuCo-founder, Ferra “Bug0 gives us the speed of AI-native automation with the accuracy of human QA. We stopped worrying about flaky tests entirely.” Jacob LauritzenHead of Engineering, Legora “We'd been putting off test coverage for months. Bug0 had our critical flows covered in under a week. No scripts, no maintenance burden.” Tomer BarneaCo-Founder, Novu “We used to skip regression tests before releases because they took too long to maintain. Bug0 runs them on every PR now. We haven't shipped a regression in three months.” Mohak SinghDirector of Engineering, Bridgetown Join these teams How your FDE gets you to full coverage.
