@bsideup AtomicJar apple/testcontainer wen?:)

Bei mir stand damals am Waldrand bestimmt 1 Jahr ein gestalteter "Testcontainer" - war nie geöffnet!

Jika pakai agentic AI untuk develop software, saya selalu wajibkan ada unit test, integration test, E2E test, API test, security test dan performance test. Tips: - integration test pakai Testcontainer biar gak ribet

#100DiasDeCodigo [139/200] Fiquei praticando alguns exercícios de algumas funcionalidades do ASP.NET Core e alguns serviços no lab do Azure. Também implementei TestContainer e teste de integração ao projeto.

writing e2e tests is hard. first setup the mock database using testcontainer, then setup the mock server and initialise all the routes and controllers, then fill the database with some dummy values. then create a request payload, serialize it and make the http call then deserialise the response body and match it against the expected response. testing the server using postman was fun honestly 😅. But anyways I think i can be done with e2e tests and then will try adding ci-cd pipeline and observaility stuffs tomorrow.

TIL : Testcontainers, when testing repository layers or any other layers which required external dependancies like postgres, mongodb, or kafka etc.. rather than spinning up a real docker container we can use testcontainer, bcz it comes with few advantages 1. Automatic clean up and restart, no manual input required 2. Fresh containers for every new functions specially if testing concurrency 3. No need to worry about ports and networking, everything gets handled out of the box 4. easy CI/CD testing as well.

Prompt saya di backend: ... Buatkan unit test dan integration test untuk test, verifikasi dan regresi meliputi positive, negative, edge cases. Convention naming : describe method -> describe positive/negative/edge case -> test. Negative test harus mencakup semua logic validasi. Jika ada logic terkait keuangan lakukan test precision loss dan rounding error. Unit test harus isolated aliran London school. Integration test harus ada full flow. Integration test gunakan : DB real, pihak ketiga semua mock, redis real, rabbitmq real. Gunakan Testcontainer untuk deploy stack-nya. Tanya saya lebih detail dan mendalam.

Ich werde son Testcontainer errichten. Machste Millionen an den Idioten.

おはようございます！！ 今日も ・3:55起床 ・3h個人開発 ・1h副業 でした！！ 昨日のTestContainer問題も解決し、テストコードも9割完了。 明日からフロントに着手する！！ 2月15日には公開したいけど、地道にコードリーディングしながらだと開発速度落ちる悩み…。 今日も一日頑張りましょう！！

おはようございます！！ 今日も ・3:55起床 ・10kmラン　 ・2h個人開発 しました！！ 個人開発の進捗； Controllerのテスト書いてたんだけど、DevContainerで作業してる中でさらにTestContainer使うとソケットやらデーモンやらで設定が必要でよくわからん〜状態。帰ってきてから続きやろう……

Emails are an external integration. They deserve real tests. In my latest blog post, I show how to test emails end-to-end in Spring Boot using Testcontainers and Mailpit. A real SMTP server. Zero manual setup. Same behavior locally and in CI. I've created a Mailpit Testcontainer module that you can drop into your tests and just use. 👉 Read the full post: martinelli.ch/testing-emails… #Java #SpringBoot #Testcontainers #Testing #Mailpit #KeepITsimple

(3/3) und auf den Spaziergängen zum Testcontainer habe ich nach und nach die Indubio-Podcasts gehört, so daß die Zeit nicht verloren war.

- PostgreSQL testcontainer with in-memory data volume - Run migrations, db init once - Make that initial db a template db - Each test that wants a db clones that template db - Use the `using` keyword in js/ts to make this very ergonomic blog.disintegrator.dev/posts…

With the database container ready, the next step is to instruct CDI to use a MongoDB container from Testcontainer during testing, rather than any production configuration. Read more 👉 lttr.ai/AlHCy #Java #Mongodb

ローカルでAIエージェント並列で回す時、テストDBが共通化されてるとバッティングするけど、TestContainerを使っていれば分離できる…かな

for point 3, I like using Verify to snapshot test HTTP responses / transactional emails with either an Aspire or TestContainer fixture that uses seed data live database. Hits all the layers and isn't brittle like a Playwright test. Doesn't work for UI / interactive tests tho☹️

It uses the same Spring Boot test context and the same Testcontainer. The tests are either creating their own test data or are isolated through separate prefilled tests data

OMG. Wir brauchen unbedingt nun an jeder zweiten Strassenecke ein paar dreckige und unhygienische Testcontainer, die von Haufen ex-Hartzern betrieben werden nach einer 30 Minuten Arbeitseinweisung

Não sei se não é de verdade, mas de fato testcontainer reproduz muito mais o ambiente e como será na prática, principalmente para teste de filas.
