Integration Tests Not Properly Mocked

まずネットワークを無効にして統合テストを実行し、launchAPI.get を割り当てている例を調べてから、打ち上げの検索を処理する RESTDataSource メソッドを追跡します。issue ではファイル名もテストコマンドも指定されていません。統合テストがオフラインで、api.spacexdata.com にリクエストせずに成功し、期待されるロケットデータを引き続き返せれば完了です。

I followed the integration tests example pattern in my own app.

   // mock the datasources' underlying fetch methods, whether that's a REST
    // lookup in the RESTDataSource or the store query in the Sequelize datasource
    launchAPI.get = jest.fn(() => [mockLaunchResponse]);

However I noticed it was still making api calls to the rest endpoint. I then cloned this repo turned off my wifi and ran the integration tests and sure enough I got an error.

    +           "type": "system",
    +         },
            },
    -       "rocket": Object {
    -         "type": "FT",

    +       "locations": Array [
    +         Object {
    +           "column": 3,

    +         },
    +       ],
    +       "message": "request to https://api.spacexdata.com/v2/launches?flight_number=30 failed, reason: getaddrinfo ENOTFOUND api.spacexdata.com api.spacexdata.com:443",
    +       "path": Array [
    +         "launch",
    +       ],

This tells me that launchAPI.get is not being properly mocked. Which I think would make sense as there is no launchAPI.get however there is a launchAPI.prototype.get however that doesn't seem to work when I change the tests to that.

Any ideas?
