Open source BrowserStack alternatives

Introducing React Storybook

“First impression : Storybook looks beautiful! Thank you for this. Developers like beautiful UIs as much as anyone. I'm currently working on a simple React.js commerce platform and even in it's early stages I'm already wrangling tens of thousands of lines of UI code. Anything to…”

Introducing React Storybook

“It looks like React Storybook uses a similar set of principles to what you're describing but organizes them for a different use case than Redux DevTools. You definitely could build something like React Storybook using Redux DevTools, but from what I understand React Storybook…”

Cypress: Fast, easy, and reliable testing for anything that runs in a browser

“I have been developing tests using Cypress for 6+ months. I have used multiple other variations of test frameworks that were built on the Selenium WebDriver protocol. The official documentation [1] states that Cypress differs fundamentally and architecturally as compared to…”

Cypress: Fast, easy, and reliable testing for anything that runs in a browser

“Not sure what you mean by "just uses your localhost". I recently set up Cypress for the app I'm working on, which is a legacy MEAN app that I've been modernizing (migrating to React+TS, etc). It already had a set of Express server API "unit tests" that were really more like…”

Bruno: Fast and Git-friendly open-source API client (Postman alternative)

“Bruno/Postman is basically curl + a filesystem + git + jq + make. If you're really comfortable with all those tools, you won't understand Postman because you'll say "why don't people just chain all these tools together?". It's like the famous hn comment on dropbox, "why don't…”

Bruno: Fast and Git-friendly open-source API client (Postman alternative)

“IDEs such as JetBrains Rider and Visual Studio offer a .http file feature for making HTTP requests, reducing the necessity of tools like Postman and Bruno, particularly for basic scenarios. Regardless, I'm happy to see Bruno as an alternative. I don't often need to test HTTP…”

The Locust Economy

“Look guys, this author just falls in love with his own analogies and leaves reality far behind. The Jefersonian Middle Class (as he calls them) isn't made up of a bunch of Groupon-client failures. They don't survive on business that has been aggregated by swarming platforms like…”

Locust – A modern load testing framework

“I used Locust for a good long time around a year back, and here are some observations. Locust is awesome to start with, and has master/slave for spawning multiple servers, great for testing real concurrency with large loads. Gatling doesn't have master/slave mode yet. Main…”

Support nested groups?

“Currently the test files support a flat list of tests, each sharing all `before` , `beforeEach`, `afterEach` & `after` hooks. I find it useful to declare nested groups with their own hooks, while inheriting context from the parent. For example I'm stubbing promise behavior and…”

Hurl 4.0.0

“That's fair, and k6 is not for everyone. JS was chosen as it's a popular language with a large web ecosystem, but the tool itself is written in Go. That said... > I got a CI-ready Hurl config working on some endpoints for work sorted within like, 5 minutes of downloading it. I'm…”

Hurl 4.0.0

“> Take a look at the docs Yeah, I did they start off with JS shenanigans, including importing packages, which immediately makes me concerned I’m going to have to deal with JS packaging dumpster-fire. There’s then one line of CLI args, followed by even more JS boilerplate. > in…”

Vitest Browser Mode Guide

“I used to do this with Karma test runner. The best part was how it didn't try to capture everything, so debugging with breakpoints was really easy. I like Vitest browser mode, but it's a pain to just "detach" for a specific frame and run that test in isolation, with my actual…”

Jest/Vitest interactive course (runs in the browser)

“100%. its a horrible code smell, and AI loves to jest.mock (or vi.mock()). (The most recent blog post on my site covers this as one of the things to look out for in AI generated tests...) in JS (with Jest/Vitest) it is far too easy to call mock()...”

Artemis II safely splashes down

“"Almost everything you said is false" and yet you could not name one thing. If my claims were wrong, you would correct them. You did not, because you can't. You claim the Artemis II review convinced skeptical experts.What actually happened was Isaacman ( or shoud I say Jared? )…”

Artemis II safely splashes down

“Do actual science. Send robots there, like Curiosity and Perseverance. And over all: start recognising that there is no point in sending humans to Mars other than "uh uh it's cool we sent someone there and they came back alive". I have nothing against the fact that it is cool.…”

E2E encrypted messaging on Instagram will no longer be supported after 8 May

“>Any e2e encryption provided by the same entity who fully controls both the blackbox clients, and the server in between, is just a security theatre that they can selectively bypass anytime with very little risk of detection. Not really much better than simple client to server…”

E2E encrypted messaging on Instagram will no longer be supported after 8 May

“Every e2e solution relies on trusting the application/tooling/crypto used. Open source is better than nothing, but is not a silver bullet for trust.”

Crash in DetoxSync

“I have an issue when running tests in parallel with `--workers 2` using `jest-circus` after upgrading to detox 18 The form tests that use the keyboard actions like `typeText` and `clearText` fail when they are running in parallel with another test. #### Reproduction 1. Have 2…”

Tests Fail Immediately

“**Describe the bug** After running the detox test command, the tests fail before doing any actions in a couple of seconds. The metro-bundler runs but the app doesn't launch past the splash screen. If I close the app and open it again the app is irresponsive. It moves past the…”

Nightwatch.js

“I'm curious why they didn't build on the "wd" implementation of the WebDriver protocol for Node.js: Personally I like just using "wd" along with a promise helper library or two. Here's an example using q-proxy ( ) and q-step ( ). The result is a pretty nice syntax (admittedly…”

Nightwatch.js

“pip install robotframework-selenium2library test.txt: *** Settings *** Library Selenium2Library *** Test Cases *** Google The Night Watch [Setup] Open Browser Title Should Be Google Input Text q nightwatch Click Button Google Search Wait Until Page Contains The Night Watch…”

Show HN: Loadjitsu – a modern load testing alternative to JMeter

“JMeter has literally hundreds more features than this. This tool (apart from the non-free licence) seems more similar to `ab` and the dozens other http benchmarking tools (like siege, wrk, httperf, and others I haven't tried), with an added basic GUI. The last time I used JMeter…”

Show HN: Loadjitsu – a modern load testing alternative to JMeter

“I can’t stand JMeter’s drag and drop test plan interface. Everything should be code. I actually prefer LoadRunner. But it’s way too expensive.”

Testcontainers

“A few examples of the difficulties I've had with testcontainers: - Testcontainers running in a DinD configuration is complex and harder to get right - Testcontainers needing to network or otherwise talk with other containers not orchestrated by testcontainers - general flakiness…”

Testcontainers

“> It may be common, but that doesn't mean it's warranted. Logical fallacies, for example, are also common (so are spelling and grammar mistakes), and yet personally I prefer to commit them less often rather than more often. You think the quotation is a fairly accurate depiction…”

Newman's Own faces mammoth tax bill after lawmakers fail to spare the foundation

“It's a plausible inference given the timing and Newman's politics while alive [1], and maybe it does apply to the other charities (I don't know one way or the other), but at least with respect to The Hole in the Wall Gang Camp (for seriously ill children), in my personal…”

Newman's Own faces mammoth tax bill after lawmakers fail to spare the foundation

“OK, so while everyone else is arguing about whether Newman's Own should be allowed to operate as it has or not, I'm curious about a different issue. What's a parliamentarian, and why can they unilaterally change bills? Or am I misunderstanding their role?”

Show HN: Doctest – C++ single-header testing framework

“no access to a linux machine - otherwise I might have tested with clang too. Also you may try the bench.py script yourself :) But this is not a benchmark of compilers but a benchmark between doctest and the other such library - and this comparison should be compiler-neutral And…”

Doctest.js: a humane Javascript test framework

“FWIW, doctest.js briefly supported CoffeeScript, back when the format was essentially language-neutral: $ makeRequest({ > url: ' > data: 'foo', > success: Spy('makeRequest', {wait: true}), > }); makeRequest(...) The example and output was parsed essentially by regexes. That was…”

Shortest-possible walking tour to 81,998 bars in South Korea

“>Our computation produced a tour together with a proof that it is a shortest-possible route [...] >These claims are provisional. Until someone produces a better tour or a valid counter-proof, this stands as the best-known solution. Are we looking at the same website? Because…”

The Shortest Papers Ever Published (2016)

“There's a related, typeset version from the Annals of Mathematics five months later, on page 9 of: While we're on the subject of brevity, page 23 has the shortest recommendation letter I've ever seen.”

Request for Review Molecule v2

“[Molecule v2]( is a huge rewrite and change. I am requesting review and feedback. ### Important changes * Addition of [Scenarios]( * Uses Ansible to manage instances vs handling internally. ### Breaking changes * Not compatible with Molecule v1 style config syntax. * Does not…”
