`ktn_meta_SUITE`

Goals

The meta suite lets you check your code with dialyzer, xref and elvis.

Usage

To include the suite in your project, you only need to invoke its functions from a common_test suite. If you use mixer you can do…

-module(your_meta_SUITE).

-include_lib("mixer/include/mixer.hrl").
-mixin([ktn_meta_SUITE]).

-export([init_per_suite/1, end_per_suite/1]).

init_per_suite(Config) -> [{application, your_app} | Config].
end_per_suite(_) -> ok.

Of course, you can choose what functions to include, for example if you want dialyzer but not elvis nor xref you can do…

-mixin([{ ktn_meta_SUITE
        , [ dialyzer/1
          ]
        }]).

-export([all/0]).

all() -> [dialyzer].
