Mocking dependencies using vitest

[carlosmoliv]

Hello everyone, how's it going?

The following mock works when I use Jest, but it doesn't work with Vitest. I understand that Vitest operates differently in this scenario, but I haven't been able to find a solution yet.

Is AwsS3Adapter a function?

Hey, it's a class

@carlosmoliv did you ever find a solution? I'm facing a very similar issue trying to mock an entire module dependency

[carlosmoliv]

It's a project that I don't work on anymore, but I checked the code to refresh my memory. I used dynamic importing:

it('should returns 200 and the document added to the program', async () => {
   // Arrange
   const program = await programDSL.createProgram(
     makeFakeCreateProgramRequest(),
   );

   const awsS3Adapter = await import(
     '@infra/gateways/storage/aws-s3.adapter'
   );

   awsS3Adapter.AwsS3Adapter.prototype.uploadFile = vi
     .fn()
     .mockResolvedValue('any_file_path');

   // Rest of the code...
});

At the top of the test suite I called vi.mock

vi.mock('@infra/storage/s3-adapter/aws-s3.adapter');

describe('Program Routes', () => {

// Rest of the code
