Are there any tests written for these examples ?

I am looking for the sample tests to test the Mutations. I tried the sample provided on the react-relay website, but the MockEnvironment is not working in my case. I am not able find out what is the exact issue.

https://relay.dev/docs/en/testing-relay-components#relaymockenvironment-api-overview

Errors I am facing:

TypeError: Cannot read property 'createOperationDescriptor' of undefined

at commitRelayModernMutation (node_modules/react-relay/node_modules/relay-runtime/lib/commitRelayModernMutation.js:33:57)
at enableHealthCheck (src/common/mutations/EnableHealthCheck.tsx:52:5)
at Object. (src/common/mutations/EnableHealthCheck.test.tsx:27:9)

Extract from commitRelayModernMutations: commitRelayModernMutation()
var _environment$unstable = environment.unstable_internal,
createOperationDescriptor = _environment$unstable.createOperationDescriptor,
getRequest = _environment$unstable.getRequest;
var mutation = getRequest(config.mutation);

Line No 1 => environment.unstable_internal is undefined in this case.

If I run same mutation with react-relay environment, this issue does not appear. This is only coming at the time of testing.

here is my code for Testing Mutation:

const {
createMockEnvironment,
MockPayloadGenerator,
} = require('relay-test-utils');

let environment: createMockEnvironment();
enableHealthCheck(environment, healthCheckInput, onCompleted, onError);
const operation = environment.mock.getMostRecentOperation();

Error is thrown when I call my mutation, which calls commitMutation.
