Testing GraphQL - From Zero To Hundred Percent

Dive into a comprehensive exploration of GraphQL testing methodologies in this 41-minute conference talk by Roy Derks at NDC Conferences. Learn why testing is crucial for all projects, especially when working with specific frameworks like GraphQL. Discover how to effectively test GraphQL schemas and queries beyond traditional JavaScript testing tools. Explore various testing approaches, including client-side testing, schema validation, resolver testing, and integration tests with server mocking. Gain insights into using Postman for GraphQL testing, implementing client-side tests, and conducting end-to-end testing. Understand the importance of test coverage while acknowledging that 100% coverage doesn't guarantee a bug-free application. Enhance your GraphQL development skills and improve overall code quality through comprehensive testing strategies.

Intro
Why write tests?
Check if errors and edge cases are handled correctly
Improves your code quality
Or test GraphQL client-side
Testing client-side
Test schemas
And for bigger schemas?
What about resolvers?
Integration tests?
With server mocking
Together with Postman
On the client-side
And end-to-end testing?
100% test coverage !== 0% bugs
