chore: bump callstackincubator/react-native-harness from 1.4.1 to 1.5.0

[dependabot]

Bumps callstackincubator/react-native-harness from 1.4.1 to 1.5.0.

Release notes

Sourced from callstackincubator/react-native-harness's releases.

v1.5.0 (2026-09-14)

🚀 Features

• Add an injectable filesystem context and in-memory filesystem helper for hermetic Harness integrations and tests. (#169, #165)

• The react-native-harness CLI now exposes harness ci <subcommand> (#185) (load-config, plan-metro-restore, snapshot-metro, plan-metro-save), which the official GitHub Action uses to run its configuration and Metro caching steps through your project's own installed CLI instead of bundled scripts checked into the action. As a result, the action now requires a react-native-harness install that supports this interface — it checks this itself via a capability marker on the installed package rather than a version number, and fails clearly when the installed CLI predates it. Keep the action ref and the react-native-harness package version in sync, as already recommended.

• Platform packages can now adjust the Metro configuration Harness composes for (#190, #187) their runner, through a metroConfigEnhancer module they point at. The bundler wiring a platform's runtime needs — module resolution redirects, additional resolver platforms, its own core initialization — lives in the platform package instead of in the bundler. Nothing changes for platforms that do not set one.

🩹 Fixes

• Harness now bounds owned CLI processes so cancelled runs do not leave console, logcat, or XCTest children behind. (#181)
• Skipped tests now appear as skipped in Jest output and compatible result consumers. (#182)
• The harness now runs on a Windows host and recognizes React Native Windows as a device platform: ESM (rn-harness.config.mjs) configs load correctly when the harness process runs on Windows, and an app reporting Platform.OS === 'windows' completes the bridge handshake instead of failing with "Unsupported platform". (#187)
• The @react-native-harness/platform-windows package now supplies its own Metro wiring through the metroConfigEnhancer hook: the react-native -> react-native-windows resolver redirect, the windows and native resolver.platforms entries, and React Native Windows' InitializeCore. A windowsPlatform() runner no longer needs any of this hand-added to metro.config.js, and @react-native-harness/bundler-metro no longer reads @react-native-community/cli-config to detect out-of-tree platforms. iOS and Android runs are unaffected. (#187)
• New @react-native-harness/platform-windows package: run harness tests against a deployed React Native Windows app. Add windowsPlatform({ name, packageName }) to rn-harness.config.mjs — the runner resolves the package family name via Get-AppxPackage, shell-activates the app by its AUMID, and tracks it by process name. Requires the app to be deployed first (react-native run-windows). (#187)
• A resource-lock heartbeat refresh that fails to write (for example the owner file racing a concurrent release, or a transient filesystem error) is now swallowed instead of surfacing as an unhandled rejection — the lock simply goes stale and is reclaimed, as it already would if the refresh were missed. (#187)
• The resource lock a platform runner defines via getResourceLockKey is now honored. Concurrent Harness runs that target the same platform but different devices — two iOS simulators, or an emulator and a physical device — no longer queue behind each other; only runs that share a device wait. Previously the key was silently dropped by config validation and every run of a platform serialized on <platformId>:<runnerName>. (#187)
