## Separating tests { #separating-tests }

In a real application, you probably would have your tests in a different file.

And your **FastAPI** application might also be composed of several files/modules, etc.

                .contentType("application/octet-stream")
                .build());
        minioClient.putObject(PutObjectArgs.builder()
                .bucket(bucketName)
                .object("dir1/file2.txt")
                .stream(new ByteArrayInputStream("file2".getBytes()), 5, -1)
                .contentType("application/octet-stream")
                .build());

It can be used by the frontend team (that can also be yourself).

It can be used by third party applications and systems.

And it can also be used by yourself, to debug, check and test the same application.

Now let's go back a bit and understand what is all that.
