Apollo Server Integration Testsuite

This package serves as a set of Jest tests for Apollo Server integration authors. Any Node package which functions as the HTTP (or HTTP framework) binding and Apollo Server can run these tests to ensure parity with the 1st party Express integration.

Note: this package is only intended for integration authors. If your project runs an Apollo Server instance, you probably shouldn't use this.

The version of this package will be published in lockstep with Apollo Server, so choose the same version of this package as the version of Apollo Server which you intend to support. The expected configuration for an integration should follow the pattern:

{
  "name": "my-server-integration",
  "devDependencies": {
    "@apollo/server": "4.1.0",
    "@apollo/server-integration-testsuite": "4.1.0"
  },
  "peerDependencies": {
    "@apollo/server": "^4.0.0"
  }
}

In the example above, the peerDependencies allow your configuration to be used with the full range of Apollo Server v4 packages. The devDependencies which your integration is built and tested against should stay up-to-date with the latest version of Apollo Server, and the server and testsuite packages should be in lockstep with each other.

This package imposes dependency requirements on your project, however it should only require they be installed as devDependencies:

• @apollo/server's version must match the version of the test suite.
• The test suite expects you to be running jest@28. It's possible that other versions of Jest may be compatible, but this use case is unsupported and might lead to unexpected behavior. It's fine for your project to use a testing framework other than Jest, but you'll still need to configure Jest in your project in order to run the test suite (so you'll have two test runners configured in your project). Because of this, we recommend using only Jest in your project for simplicity.
• graphql must be installed in your project in peerDependencies and your version range should match that of @apollo/server. The test suite package's graphql dependency will match that of Apollo Server's.
