NAME

Test::Nginx::Socket::Lua::Stream - Subclass of Test::Nginx::Socket::Lua to test NGINX stream modules

SYNOPSIS

    === TEST 1: simple test for ngx_stream_echo_module
    --- stream_server_config
    echo "Hello, stream echo!";

    --- stream_response
    Hello, stream echo!

    --- no_error_log
    [error]
    [alert]

Description

This module subclasses Test::Nginx::Socket::Lua to provide handy abstractions for testing NGINX stream-typed modules like ngx_stream_echo_module.

By default, the stream server listens on the port number N + 1 where N is the value of the environment "TEST_NGINX_SERVER_PORT" or "TEST_NGINX_PORT" (both default to 1984). One can explicitly specify the default stream server's listening port via the "TEST_NGINX_STREAM_PORT" environment.

Sections supported

All the existing sections of Test::Nginx::Socket::Lua are automatically inherited.

The following new test sections are supported:

stream_config

Specifies custom content in the default "stream {}" configuration block.

stream_server_config

Specifies custom content in the default "server {}" configuration block (inside "stream {}") in nginx.conf.

For example,

    --- stream_server_config
    echo "hello";

will generate something like below in nginx.conf:

    stream {
        server {
            listen 1985;
            echo "Hello, stream echo!";
        }
    }

stream_server_config2

Specifies a second stream server which listens on the port used by the first default server plus one.

stream_server_config3

Specifies a third stream server which listens on the port used by the first default server plus two.

stream_request

Specifies the request data sent to the first default stream server (defined by "stream_server_config".

stream_request2

Specifies the request data sent to the second default stream server (defined by "stream_server_config2".

stream_request3

Specifies the request data sent to the third default stream server (defined by "stream_server_config3".

stream_response

Specifies expected response content sent from the default stream servers. For example,

    === TEST 1: simple echo
    --- stream_server_config
    echo "Hello, stream echo!";

    --- stream_response
    Hello, stream echo!

When multiple default stream servers are specified (i.e., via "stream_server_config2" and "stream_server_config3", the responses from all these stream servers are concatenated together in the order of their specifications.

stream_response_like

Specifies the regex pattern used to test the response data from the default stream servers.

log_stream_response

Print out the stream response to the nginx error log with the "info" level instead of sending it out to the stream client directly.
