Very good advice, though it doesn't answer the question nor address the
actual post I made in any way.
I am very familiar with testing methodologies and technologies. Just
most of my recent experience was with Java, where it's relatively easy
to start a mock http server in a separate thread. Not as easy in PHP.
I'm asking about Mock HTTP servers. Not about testing.
Thanks,
Daniel.
