Testkit fails to execute query

[Brian-McBride]

Testkit not executing query (or mutations) using testkit.execute()

Problem

I'm having issues with testkit even running resolvers. Like a todo app:

    const app = testkit.testModule(todosGraphqlModule);
    expect(app.schema.getQueryType()).toBeDefined();
    expect(app.schema.getMutationType()).toBeDefined();

    const graphResult = await testkit.execute(app, {
      document: gql`
        query getTodo($id: ID!) {
          id
          title
        }
      `,
      variableValues: {
        id: 'someId',
      },
    });

    console.log(graphResult);  // output is:  { data {} }

Seems pretty simple. If I run the code in my app, the resolvers run as expected. But running this in Jest I always get { data {} } as a result, and the resolvers are never executed.

Expected behavior

The response from the test should run the query and return its value.

Environment:
