Attendee notes that in React, component tests often rely on artificial supplied data that drifts from the real backend, and asks whether being in Rails makes it easier to test ViewComponents with real data. Answer: write a spec file with factory-built objects and regular RSpec assertions on what should/shouldn't be rendered, use snapshot testing to detect changes, and use Rails system tests for end-to-end flows that involve Turbo Stream or Turbo Frame requests. Asked which is better to test, Yaroslav says personally he prefers writing Ruby assertions for ViewComponents — easier for him as a Ruby developer.
