Application unit tests are stored in test/apps/webapp/ and test/apps/webpeer/. Both the unit and browser tests remain outside src, because test-file ignores do not apply to the Community Review source boundary.

Each application has its own production-bundle smoke-test directory outside src:

test/browser-apps/webapp/ covers Vault selection, OPFS start-up, and isolation between optional P2P settings and the main remote.
test/browser-apps/webpeer/ covers start-up, settings persistence, and reload.
test/browser-apps/pages/ covers the final GitHub Pages layout, application subpaths, and relative assets.

Run both app-owned tests with:

npm run test:browser-apps

test/browser-apps/interop.test.ts is the only cross-application scenario. It configures the real WebApp and WebPeer interfaces, transfers a file from WebApp to WebPeer, then starts the built CLI as the final peer and verifies the file through the production CLI. The CLI is a test fixture in this scenario; the PoC test and its support code are not owned by the CLI package.

Run the isolated relay and TURN scenario in Compose with:

npm run test:e2e:browser-apps:interop

After assembling the GitHub Pages files in _site, run the package smoke test with:

npm run test:browser-apps:pages

Set PAGES_SITE_ROOT to test an assembled site in another directory.

The Deno dependency lock is shared only by these browser application tests.
