Also covered: Playwright-based mobile testing tool Tap-in hitting 1.0, an open-source Agentic Playwright scaffolding template for AI coding agents, a critique of performance testing maturity from James Pulley, Blacksmith's $45M raise for CI validation and its Codesmith agent, an open-source Playwright learning platform called Play Sensei, upcoming TestMu 2026 conference, and a webinar on agentic QA validation layers. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What changed in Selenium 4.47 regarding Firefox and CDP? Selenium 4.47 makes Firefox block CDP (Chrome DevTools Protocol) access for the .NET, Python, and Ruby bindings, reinforcing WebDriver BiDi as the standard cross-browser protocol going forward. The release also unifies the BiDi layer across bindings using a shared binding-neutral schema, with Ruby now generating BiDi type accessors, union variant factories, and type errors from that schema, matching JavaScript's existing implementation. _Track Selenium version changes like this on daily.dev before a CDP dependency breaks your suite._ ### What is Agentic Playwright and how do I set it up? Agentic Playwright is an open-source Playwright and TypeScript scaffolding template built for teams that let AI coding agents write their tests, released under the MIT license on GitHub. Running the command npm create agentic-playwright with a demo flag scaffolds the framework, installs dependencies and a browser, and runs a smoke test against a live demo app in under five minutes, including page objects, dependency injection fixtures, Zod-based API testing, stored-state authentication, and a constitution file with 17 skills for governing agent behavior across Claude Code, Cursor, and Copilot. _Developers wiring AI agents into test suites can follow tools like this via daily.dev._ ### How much did Blacksmith raise and what does its Codesmith product do? Blacksmith, a cloud platform for validating code, raised $45 million, announced in mid-August. CI jobs running on Blacksmith have grown 5-10% week over week since the start of the year, with customers including Supabase and Clerk. Its Codesmith product is a cloud coding agent that diagnoses CI failures, autofixes them, and keeps pull requests green, and it also underpins the upcoming Codesmith QA for autonomous pre-merge testing. _Anyone evaluating AI-driven CI validation tools can follow funding and product moves like this on daily.dev._ ## Similar posts on daily.dev - [Selenium vs Cypress vs Playwright: Choosing Your Test Automation Framework](https://daily.dev/posts/selenium-vs-cypress-vs-playwright-choosing-your-test-automation-framework-3uxew2qph) · Stack Overflow Blog · 4 upvotes · 0 comments - [The AI-augmented tester is here.
