There is no end, write methods. The Readme end is not fixed yet
[#8] Revert changes to test suite

- No need to test for the absence of methods; doing so would be confusing for
  those maintaining the library.
[#8] Remove all remaining references to obsolete functionality

- Removed references to response `write()`, `end()`, and `isComplete()`
  methods, and all references to `Phly\Http\ResponseInterface`.
- Fixed descriptions of usage of response and server instances to refer
  to actual methods and/or class types.
- Updated composer instructions to refer to psr/http-message `~0.2.0@dev`
Merge branch 'hotfix/8'
