Create request tests

[cojoj]

Oi! 🇬🇧

I've created test suite for XcodeServerEndpoints with purpose of testing createRequest() but it looks like it's mostly tested (or at least covered in other tests), so I've only created test case for malformed URLs passed to this method.

We're missing code coverage for those lines:

catch {
    let error = error as NSError
    Log.error("Parsing error \(error.description)")
    return nil
}

but it's complicated as I can't invent any failable case for NSJSONSerialization.dataWithJSONObject() as earlier we make sure we pass NSDictionary and any valid dictionary will be a valid JSON in that case.

Still no update for guard statement bug and code put directly after guard is never marked in test coverage... 😭

Ignore Bitrise, I was testing it and it just doesn't work.

Anyway - to your PR, looks good. To your question - if we can always just use createRequest, then we shouldn't be testing a case that can never happen. So I think it's fine.

Do you want to add more tests to this PR (is this WIP?)

[cojoj]

Nah, it's ready to merge as there's nothing more to test ATM!

One more thing... Let me put some emoji

😏

Okey, now it's ready 😆👍
