✅ Create basePlugin tests

[BeltranBulbarellaDD]

Motivation

The plugin E2E test scenarios (Angular, Vue, React, Next.js) were duplicated across each framework's scenario file. Every plugin tested the same core router behaviors but each had its own copy.

Changes

• Extracted the 6 common plugin test scenarios into test/e2e/scenario/plugins/basePluginTests.ts:
  The base tests are:

  • Tracks initial View
  • Normalizes dynamic routes and has correct referrer.
  • View contains Loading_time
  • Do not create a view when query params change.
  • Should create a new view when the dynamic url changes.
  • Reports client side errors.

• Reorganized all plugin scenario files into a test/e2e/scenario/plugins/ subdirectory (angular, vue, react, nextjs, plugin).

• Replaced id-based element selectors (#error-button) with data-testid attributes across all test apps.

• Framework-specific tests that don't fit the shared suite remain in their own test.describe blocks (Angular nested routes / wildcard / error handler, React splat routes / vital events / error boundary details, Next.js parallel routes / server errors / global errors).

• Removed all unused code from the tests apps.

• Removed the firefox check on React tests.

Test instructions

# Build test apps first (required before running E2E)
yarn build:apps

# Run all plugin-related E2E scenarios
yarn test:e2e -g "angular|vue|react|nextjs"

# Or run each plugin file individually
yarn test:e2e --spec test/e2e/scenario/plugins/angularPlugin.scenario.ts
yarn test:e2e --spec test/e2e/scenario/plugins/vuePlugin.scenario.ts
yarn test:e2e --spec test/e2e/scenario/plugins/reactPlugin.scenario.ts
yarn test:e2e --spec test/e2e/scenario/plugins/nextjsPlugin.scenario.ts

Verify that all shared scenarios (initial load, dynamic route normalization, SPA loading time, hash-only nav, query-param-only nav, same-route different URLs, client error) pass for each framework.

Yeah nice! At first glance:

• We could decouple routing and error in BasePluginTests. It would simplify config and let us use it even if only routing is implemented.
• We could make sure the grouping of describe is more consistent (see screenshot).
