failing tests about bybit

maybe checking the return code and return message will suffice and will make the tests more robust?

As a matter of fact, I didn't think much about it.

To begin with, I prepared the tests to understand the change in response.

But, I agree with you in terms of testing for CI.

On the other hand, in order to understand the change in response, it may be a good idea to separate the directory as shown below so that we can check it easily.
