Add end-to-end test coverage for critical user flows #16
Description
User Story
As a fellow engineer, I want browser-level end-to-end tests for critical flows so that regressions in wallet connection and portfolio rendering are caught early.
Context
Unit tests are not enough for a wallet-driven app. This issue should define a lightweight E2E testing strategy for critical user paths.
Acceptance Criteria
- An E2E framework is configured and documented
- At least one critical happy path is covered end to end
- The chosen path should represent a real user workflow such as wallet connection or dashboard rendering
- Tests can run in CI in a stable way
- Test data or environment assumptions are documented clearly
Notes
- Keep the first scope intentionally small and reliable
- Avoid brittle tests that depend on many external services unless mocked intentionally
- This issue is about building confidence, not maximum test count
Out of Scope
- Full regression suite
- Cross-browser matrix in the first pass
