Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/52777 Changelog: [internal] This significantly speeds up test execution in Fantom (around 2x in OSS and 6x at Meta) by starting a Metro server before all tests runs and reusing it across all tests to build test bundles, instead of spinning up a new Metro instance every time we run each test. The architecture change (also considering the previous change in buck prebuilds) looks like this: {F1980689532} This is how is impacts execution times (compared to the baseline): * OSS * Before: 62s {F1980564286} * After: 30s (**2x faster**) {F1980564265} Reviewed By: andrewdacenko Differential Revision: D78741903 fbshipit-source-id: b209f88925e49cc2a2067e8df9b7fa9a29b4c8d2
