Test::Nginx::Socket::Lua::Dgram(3) User Contributed Perl Documentation Test::Nginx::Socket::Lua::Dgram(3)

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

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

    --- dgram_response
    Hello, stream echo!

    --- no_error_log
    [error]
    [alert]

This module subclasses Test::Nginx::Socket::Lua to provide handy abstractions for testing NGINX UDP 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_DGRAM_PORT" environment.

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

The following new test sections are supported:

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

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

For example,

    --- dgram_server_config
    echo "hello";

will generate something like below in nginx.conf:

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

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

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

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

Specifies the request data sent to the second default stream server (defined by "dgram_server_config2".

Specifies the request data sent to the third default stream server (defined by "dgram_server_config3".

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

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

    --- dgram_response
    Hello, stream echo!

When multiple default stream servers are specified (i.e., via "dgram_server_config2" and "dgram_server_config3", the responses from all these stream servers are concatenated together in the order of their specifications.

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

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