Any hints on how to implement resource sharing in ExUnit tests? For phoenix_test_playwright, I want shared browser instances. Browser pool, each test module has to wait for available browser in `setup_all`. github.com/ftes/phoenix... Have you seen/implemented something similar before? #elixirlang

We asked two questions at our talk "Let it Crash - Designing Robust Systems". What are your building blocks for robust systems? How do you find a misbehaving part of your software? Great answers in thread👇 My takeaway: The BEAM provides. Little need for other tools. #elixirlang #devconnectowl

PhoenixTestPlaywright 0.8 released 🎉 - ⚡️ speed up refute_has - ✅ support bunx - ✅ support phoenix_test 0.8 And other quality of dev-life improvements. #elixirlang

learndmarc.com Nice fresh semi-interactive take on both checking and explaining Email security.

Sharing this with a big recommendation. You'll have a hard time finding someone as knowledgeable as @hauleth.dev

phoenix_test_playwright user base has grown to 50% of phoenix_test (judging by number of downloads in past 7 days). Surprises: 1. High number of users. Metric skewed by few power users? 2. Low support effort. Lib is 90% undocumented playwright internals. Playwright js frequently updated. #elixirlang

Local code review = more collaboration (everybody edits/shares/reviews) This really resonates with me, I have often wished for that. youtu.be/MUqvXHEjmus?...

LiveView colocated hooks: Skip for now due to lack of tooling support? 1. Code highlighting 2. JS Intellisense (language server features) 3. Formatting 4. Unit testing Any thoughts? Some of mine in thread 👇 #elixirlang

Can ExUnit.CaseTemplate `setup` order be influenced? I'd like my CaseTemplate `setup` callback to receive context values from my use-ing Test `setup` callback. Use case: Override Playwright browser options when opening new page. github.com/ftes/phoenix... #elixirlang

Common phoenix pitfalls when upgrading to LiveView 1.1 Tests may break in several ways. - HTML boolean attrs like 'checked' rendered differently - stricter CSS selectors due to lazy_html - phoenix_test needs fix #45 (unreleased) #elixirlang

"Now you can use any [Tailwind combobox] in any project you're working on — no JavaScript framework required." tailwindcss.com/plus/ui-bloc... This is going to make LiveView even more fun. I guess this makes waiting for vanilla-js headlessui obsolete. #elixirlang

Essential trick for cross-platform #elixirlang release via docker: ENV ERL_AFLAGS "+JMsingle true" Apple Silicon -> linux/amd64 Without this, no luck (core dump, memory alloc, ... you name it). For both Docker VMM and Apple Virt Framework (no Rosetta).

"LiveView does the same thing as Eclipse RAP 15 years ago" "Unusable as soon as there is network latency" Great comment I heard yesterday at #jugpb talk on #elixirlang Offline mode? Latency >500ms -> Don't use LiveView Most business SaaS incl. mobile -> Use LiveView Let's dig deeper 👇

Elixir list op associativity gone wrong: I wrote a -- b -- c and meant (a -- b) -- c but got a -- (b -- c) mix format made that more obvious by adding brackets - in the "wrong" place. But I still missed it. Code review and tests to the rescue. #elixirlang

"The Future of Feature Tests" Should I submit that talk for #codebeam Berlin 2025? - AI assisted writing + maintaining (playwright MCP + Tidewave) - faster execution: Lightpanda - status update: phoenix_test + playwright Interesting? What should I focus on? Would ❤️ your feedback! #elixirlang

Introducing Tidewave: tidewave.ai While working on our web apps, we run code, query the database, read logs, search docs… but our AI tools are limited to reading code. Tidewave closes this gap by introducing Runtime Intelligence, for Phoenix and Rails. More coming soon, check out the website!

lightpanda.io Lightpanda (WIP headless browser from scratch) explicitly mentions playwright as use case now. Should be able to benefit in phoenix_test_playwright soon if we add websocket support. #elixirlang

I wrote about something very close to my heart: how to make ALL the tests async in @elixir-lang.org. Enjoy! 🏎️ andrealeopardi.com/posts/async-...
