I'll fix it later.

For the DAP test, the fix is the same as: https://github.com/ruby/debug/pull/640/files#diff-edcbc39076c34506ea43bae159c4b26104156861edc7b84224e85cc4e980d355

Oh, I see.

Could you create the PR instead of me?

@ono-max Do you agree to drop the detach raw test? I think in this case it's unnecessary because the request test cover the exact same behavior. The rest of requests have also been tested in other parts of request tests.

Thank you for asking me. I think that more test cases are better than less test cases, though?

Although I wrote the raw test in https://github.com/ruby/debug/pull/705, I'll close it if you disagree with it.

That's true but we also need to consider the maintenance cost. If you look at #705, you can see that the test content may have been outdated for a while. And that makes me think:

• If we go stricter on matching the req/res, it'll need to be updated more frequently. But until now the missed changes don't seem to cause issues, so perhaps it's fine to keep it this way?
• If we decide that a rough behavior match like the current one is good enough, why don't we just maintain the request tests?

I of course appreciate your work on #705 so I don't think we should close it. But if the raw tests in the current form are worth maintaining is debatable imo.

How about this: if you can list one or more scenarios that a raw test case covers that its request counterpart doesn't, we keep it. In addition to that, we should also document it done in the file so it'll help us maintain it. If not, we remove it.
