Fast 'end-to-end' testing with GraphQL


End-to-end testing has always been painful, but GraphQL can help. The GraphQL-first paradigm allows a new way of testing that gives us the confidence of true end-to-end tests without needing both client and server running, and without heavy end-to-end testing tools.

The promise of GraphQL in testing

What if we could use GraphQL to tie together client and server tests to give us an “end-to-end” test that was fast and reliable? The same strengths that give us GraphQL-first development can grant us full-stack testing superpowers. You will see a way to test that is:

  • fast: like unit tests
  • cohesive: client and server tests can be proven via GraphQL to implement a full end-to-end process
  • independent: client and server tests can be run separately
  • end-to-end: able to run from client input through the back-end back to rendered component trees

This talk discusses an approach to mapping from stakeholder requirements to new features using a test-driven, GraphQL-first approach.
