Katana Test is an Erlang library application containing modules useful for testing Erlang systems.
It currently contains the module ktn_meta_SUITE, which is a Common Test suite to be included among your tests. Read below for more information.
If you find any bugs or have a problem while using this library, please open an issue in this repo (or a pull request :)).
And you can check all of our open-source projects at inaka.github.io
The meta suite lets you check your code with dialyzer, xref and elvis.
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].ktn_meta_SUITE uses the following configuration parameters that you can add to the common_test config for your test suite:

xref_config |
