Install libplack-test-anyevent-perl by entering the following commands in the terminal:
sudo apt update sudo apt install libplack-test-anyevent-perl
run Plack::Test on AnyEvent-based PSGI applications
Plack::Test::AnyEvent allows you to easily test your AnyEvent-based PSGI applications. Normally, Plack::Test::MockHTTP or Plack::Test::Server work fine for this, but this implementation comes in handy when you'd like to test your streaming results as they come in, or if your application uses long-polling. For non-streaming requests, you can use this module exactly like Plack::Test::MockHTTP; otherwise, you can set up a content handler and call $res->recv. The event loop will then run until the PSGI application closes its writer handle or until your test client calls send on the response.
