* This file exists to allow overriding the various output-related functions

|
* in order to test what happens during the `Server::listen()` cycle.
|
|
*
|
|
* These functions include:
|
|
*
|
|
* - headers_sent(): we want to always return false so that headers will be
|
|
* emitted, and we can test to see their values.
|
|
* - header(): we want to aggregate calls to this function.
|
|
*
|
|
* The HeaderStack class then aggregates that information for us, and the test
|
|
* harness resets the values pre and post test.
