Bug 134729 – WebKitTestRunner: centralize getting tests and sending results to a singleton

• Status: ASSIGNED
• Component: Tools / Tests

[David Farler]

WebKitTestRunner should be getting the next test path and sending results to a singleton that speaks the Layout Test Protocol. The singleton should be able to work with standard file descriptors or a single socket to allow layout test scripts to talk to iOS (over a wrapper on this host) without the FIFO hack.

Some possible abstract methods:
- nextPath() // reads from stdin or socket
- addRenderTree(...) // saves to ivar
- addImage(...) // saves to ivar
- addAudio(...) // saves to ivar
- addErrorText(...) // saves to ivar
- done() // sends results over stdout/stderr or socket
