Direção de pesquisa

Comece por scripts/objc-test.sh, por volta das linhas 54–70 e 132–135. Em seguida, inspecione os testes de integração do RNTester e a exclusão vinculada no PR #59433. Confirme se algum teste restante precisa do servidor WebSocket na porta 5555 e atualize o script de teste para corresponder aos testes atuais. O trabalho estará concluído quando yarn test-ios passar pela inicialização do servidor e prosseguir para o packager e a compilação do RNTester.

Descrição

Description

yarn test-ios (scripts/objc-test.sh test) starts the WebSocket test server with sh "./IntegrationTests/launchWebSocketServer.sh" & from packages/rn-tester, then waits for localhost:5555 to answer (L132-L135). https://github.com/react/react-native/pull/59433 deleted packages/rn-tester/IntegrationTests/, that script and websocket_integration_test_server.js among it, so waitForWebSocketServer polls sixty times and exits 1: on main the command stops before it builds RNTester or runs a test. No test left on main connects to port 5555.

No GitHub job runs yarn test-ios (#59596), and #59666, which turns it on in test_ios_rntester, counts on the script starting that server.

Steps to reproduce
  1. On macOS, in a checkout of main (0e4af152b8), run yarn test-ios; or run bash repro.sh from the reproducer below, which runs scripts/objc-test.sh test in a sparse clone of main with lsof stubbed, so the script's cleanup kills nothing listening on 8081 or 5555.

Expected: the script gets past the WebSocket server step to the packager and builds RNTester for testing.
Actual: it prints sh: ./IntegrationTests/launchWebSocketServer.sh: No such file or directory, retries localhost:5555 for a minute and exits 1 with WebSocket Server did not respond in time. No more attempts left.

SUMMARY: yarn test-ios stops before building RNTester: it launches packages/rn-tester/IntegrationTests/launchWebSocketServer.sh, which is missing, and exits 1 when nothing answers on localhost:5555
MANDATORY Reproducer

https://gist.github.com/YevheniiKotyrlo/6235683cdbbb2507855f997fa6023f79 — bash repro.sh exits 1 while yarn test-ios stops at the WebSocket server and 0 once it gets past it to the packager.
