DESCRIPTION

This module provides a test scaffold based on LWP::UserAgent for automated testing in Nginx C module development.

This class inherits from Test::Base, thus bringing all its declarative power to the Nginx C module testing practices.

You need to terminate or kill any Nginx processes before running the test suite if you have changed the Nginx server binary. Normally it's as simple as

  killall nginx
  PATH=/path/to/your/nginx-with-memc-module:$PATH prove -r t

This module will create a temporary server root under t/servroot/ of the current working directory and starts and uses the nginx executable in the PATH environment.

You will often want to look into t/servroot/logs/error.log when things go wrong ;)

Sections supported

The following sections are supported:

config
http_config
request
request_headers
more_headers
response_body
response_body_like
response_headers
response_headers_like
error_code
chunked_body
middle_chunk_delay
start_chunk_delay
