Bug: Test Env fails when the output path does not have access to @eventual/core

[thantos]

When the ourDir does not have access to @eventual/core, the test env will fail to import the bundled service code.

The tests do not currently bundle the the @eventual/* packages in, intending to use the copy that the test is using to being closer to the test.

Looks like the test env should just bundle and let their be two copies for now.

Bundling all dependencies breaks mocking.

For example, if I try to mock sqs, it will mock the instance imported by the tests, and not the bundled one in the test service.

jest.mock("@aws-sdk/client-sqs", () => {
  return {
    ...(jest.requireActual("@aws-sdk/client-sqs") as any),
    SQSClient: jest
      .fn()
      .mockImplementation(() => ({ send: fakeSqsClientSend })),
  };
});

For now, the service file bundled by the tests MUST be able to find the node_modules of the test workflow.

  env = new TestEnvironment({
    entry: path.resolve(
      url.fileURLToPath(new URL(".", import.meta.url)),
      "./workflow.ts"
    ),
    outDir: path.resolve(
      url.fileURLToPath(new URL(".", import.meta.url)),
      ".eventual"
    ),
  });
