Feature Example - Testing

This project demonstrates how to write tests against the GraphQL API to your Keystone system. It builds on the withAuth() example project.

Instructions

To run this project, clone the Keystone repository locally, run pnpm at the root of the repository then navigate to this directory and run:

pnpm dev

This will start the Admin UI at localhost:3000. You can use the Admin UI to create items in your database.

You can also access a GraphQL Playground at localhost:3000/api/graphql, which allows you to directly run GraphQL queries and mutations.

Features

Keystone provides a testing library in @keystone-6/core/testing which helps you write tests using Jest. This example project uses this library to add tests to the withAuth() example project. The tests can be found in example.test.ts

Running tests

The project's package.json includes a script:

    "test": "jest"

We can run the tests by running the command

pnpm test

which should give output ending with:

 PASS  ./example.test.ts
  ✓ Create a Person using the Query API (183 ms)
  ✓ Check that trying to create user with no name (required field) fails (116 ms)
  ✓ Check access control by running updateTask as a specific user via context.withSession() (198 ms)
