test: add automated build environment display to RC and production builds. by sleepytanya · Pull Request #29390 · MetaMask/metamask-mobile

sleepytanya · 2026-04-28T04:39:03Z

Description

Adds automated build environment display to RC and production builds. Captures actual environment values used during builds (METAMASK_ENVIRONMENT, METAMASK_BUILD_TYPE, API URLs, etc.) and displays them:

RC builds: In PR comment alongside build links
Prod builds: Extracted via new workflow (Slack notification in follow-up PR).

Changes:

scripts/apply-build-config.js: Add --write-build-env flag to generate build-env.json with actual env values
build.yml: Generate and upload build-env.json as artifact during builds (used by both RC and
prod)
build-rc-auto.yml: Download build-env artifacts in post-rc-build-comment job
scripts/build-announce/: Add env section to RC build PR comments
prod-build-env-notify.yml: New workflow triggered on prod build completion, extracts env values (Slack posting in follow-up PR)

Pre-merge author checklist

I've followed MetaMask Contributor Docs and MetaMask Mobile Coding Standards.
I've completed the PR template to the best of my ability
I've included tests if applicable
I've documented my code using JSDoc format if applicable
I've applied the right labels on the PR (see labeling guidelines). Not required for external contributors.

Performance checks (if applicable)

I've tested on Android
- Ideally on a mid-range device; emulator is acceptable
I've tested with a power user scenario
- Use these power-user SRPs to import wallets with many accounts and tokens
I've instrumented key operations with Sentry traces for production performance metrics
- See trace() for usage and addToken for an example

For performance guidelines and tooling, see the Performance Guide.

Pre-merge reviewer checklist

I've manually tested the PR (e.g. pull and build branch, run the app, test code being changed).
I confirm that this PR addresses all acceptance criteria described in the ticket it closes and includes the necessary testing evidence such as recordings and or screenshots.

Note

Medium Risk
Changes CI build workflows and the RC PR-comment pipeline to generate, upload, download, and parse a new build-env.json artifact; misconfiguration could break build jobs or PR comment posting. Risk is limited to CI/reporting paths and is largely non-blocking (continue-on-error/|| true) but still touches release build automation.

Overview
Adds generation of a build-env.json file during CI builds (via scripts/apply-build-config.js --write-build-env) and uploads it as a build artifact for each platform.

Updates RC automation to download these artifacts and extends scripts/build-announce to parse them and include a Build Environment section (env/build type, remote FF mapping, key API URLs/flags) in the RC PR comment, with a fallback “not available” section on extraction failure.

Introduces a new Prod Build Env Notify workflow that triggers on successful production workflow runs, downloads the build-env artifact, extracts key values with jq, and currently prints a placeholder for a future Slack notification; also ignores local build-env.json via .gitignore.

E2E Test Selection:
All 9 changed files are exclusively CI/build infrastructure and scripting changes with zero impact on app source code or test infrastructure:

GitHub Workflows (build.yml, build-rc-auto.yml, prod-build-env-notify.yml): Changes add build environment artifact generation/upload/download steps and a new notification workflow. All new steps have error-tolerant fallbacks (continue-on-error: true, || true). No changes to existing build steps, test execution, or app compilation logic.
scripts/apply-build-config.js: Adds a new --write-build-env CLI mode that writes build environment values to build-env.json. Existing --export and --export-github-env modes are completely unchanged. No impact on how the app is built or configured.
scripts/build-announce/: New TypeScript files for displaying build environment info in RC PR comments. This is purely a developer tooling/notification feature with no connection to app functionality or E2E tests.
.gitignore: Adds build-env.json to gitignore - trivial change.

None of these changes affect:

Any React Native app components or screens
Any controllers, reducers, or state management
Any navigation or routing logic
Any E2E test infrastructure (tests/, page-objects/, fixtures/, .detoxrc.js)
Any app build configuration that would change app behavior

Running E2E tests would provide zero validation value for these changes. No performance tests are needed either as no performance-sensitive code paths are touched.

Performance Test Selection:
No performance-sensitive code changes. All changes are CI/build tooling scripts and workflow files that have no impact on app rendering, data loading, state management, or any user-facing performance characteristics.
