🚨 NEWS: Jest testing JavaScript e TypeScript completo: guida operativa
Ecco i punti chiave in breve:
💡 Hai scritto una funzione, l'hai testata a mano in console.log, sembra funzionare, la mandi in produzione e dopo due giorni arriva la segnalazione: “non funziona quando l'input è negativo”. Lo vediamo...

Вы неправильно тестируете асинхронный код: тест проходит раньше, чем выполняется проверка
В статье разберём, как именно раннер решает, что тест прошёл, почему .then без return выполняется уже после теста, почему try/catch в async‑тесте — частый источник ложного зелёного, что не так с forEach и setTimeout внутри тестов и какие инструменты не дают тесту соврать. Примеры на Jest, но контракт у Mocha, vitest и прочих тот же.

A quotation from Samuel Johnson
Merriment is always the effect of a sudden impression. The jest which is expected is already destroyed.Samuel Johnson (1709-1784) English writer, lexicographer, critic

Narasimha is the fourth incarnation of the #Hindu god Wishnu. For reasons, rage is a key trait of Narasimha, especially early in the incarnation. #trivia
Yesterday (Thursday) was "Narasimha Jayanthi", the birthday of Narasimha. The occasion is observed with pomp in Waisnavite locations across #India.
I of course attended the Narasimha Jayanthi festivities in #Udupi. Of the many people I encountered, two were rather rude and directed some anger at me, which I thought I didn't deserve. Still, I handled one of them right, which is by ignoring them; but I think I responded a wee bit in kind to the second. 😳
Needless to say, those two interactions left a bitter taste in me, but I later consoled myself that maybe it was just that Narasimha cast his shadow on some people that day, what with him having just been born. 😀
PS: Anyway, enjoy this presentation of Udupi Krishna on the special day:
Thanks, white boy!
... but my dick ain't THAT big.
Making Our Frontend Unit Tests Much Faster With @ swc/jest, by (not on Mastodon or Bluesky):

We were annoyed with the slow performance of our frontend unit tests, so we made them much faster! It turned out that swapping out the test runner is an easy and efficient way to keep the migration effort low, while reaping the benefits of much faster execution times.

QA в CI/CD: как перестать гонять тесты руками и настроить это один раз
Разбираю как выглядит нормальный QA-пайплайн в GitHub Actions: от линтинга до E2E тестов на Playwright. С рабочими конфигами, кэшированием и уведомлениями о падениях.
